Treating your Clothes with Permethrin

Sawyer Permethrin - Kills Ticks on Contact

Sawyer Permethrin – Kills Ticks on Contact

Permethrin is a contact pesticide that kills black flies, ticks, and mosquitoes on contact but has no harmful side effects on humans if used properly. It is the active ingredient used in Insect Shield and Buzz Off clothing and kills bugs when they land on your clothing by overloading their nervous system. You can buy Permethrin in liquid form and spray it on your own clothes to the same effect. This self-applied form lasts for 4-6 washings. Permethrin was developed by the U.S. military to protect soldiers from insects in the jungle.

You can buy Permethrin on Amazon. A big bottle comes with a spray adapter and will cover 4 complete sets of clothing, including shirts, pants, and socks. You’ll want to read the directions carefully before applying it, but it’s not difficult to do. You need to spray it on the clothes you plan to wear hiking or for any outdoor activity in a windless but well ventilated place like a garage. Let them dry for a few hours and you’re all set.

I’ve been spraying Permethrin on the clothes that I wear for spring and summer hiking in New Hampshire and Vermont for over 4 years. This has included long sleeve shirts, convertible hiking pants, short gaiters, underwear, gaiters, and hiking socks. When you spray the Permethrin on, you want to position the sprayer 6 to 8 inches away from the clothing you plan to treat. Pay particular attention to the cuffs of long pants and shirt sleeves where the bugs will try to attack you. It’s also a good idea to spray it on your hat or to buy one that’s already been treated with Permethrin like the Outdoor Research Sentinel Brim Hat. which is what I wear.

I can attest to the effectiveness of Permethrin particularly against mosquitos and ticks. I rarely ever get bitten, maybe one or two bites per year, as long as I wear long-sleeved shirt and pants when I go hiking in the forest. I love having the sun on my arms and legs as much as the next guy, but I’d rather cover up than catch Lyme disease, which the CDC believes is now 10 times more prevalent than previously reported.

More about Permethrin

As a treatment for clothing, Permethrin clothing insect repellent does not harm fabrics and is odorless after dried. Use Permethrin on clothing by itself or with skin-applied repellents to create the ultimate protective, armor-like insect barrier. Permethrin-treatments on clothing are non-toxic to humans and are registered for use by the U.S. EPA.

The active ingredient, Permethrin, is a synthetic molecule similar to those found in natural pyrethrum, which is taken from the chrysanthemum flower. Not only does this product repel insects, but will actually kill ticks, mosquitoes, chiggers, mites and more than 55 other kinds of insects.

Permethrin insect repellents are for use with clothing, tents, and other gear. During the drying process, it tightly bonds with the fibers of the treated garment. It will not stain or damage clothing, fabrics, plastics, finished surfaces, or any of your outdoor gear.

Permethrinis a contact insecticide. It kills ticks or other insects when it comes in contact with them. It uses the same active ingredient used in hair shampoos for head lice. When applied to clothing, the Permethrin binds to the fabric eliminating the risk of over-exposure to the skin. As a clothing, tent, chairs, or sleeping bag application, Permethrin is very effective at keeping ticks from attaching to you and at reducing the mosquito population in your camping area. While ticks usually find you at the ankle level (be sure to treat the socks and pants) they can also climb bushes and find you at a higher level so be sure to treat your shirt as well if you are around bushes and concerned about ticks.

Sweating and exposure to water do not significantly deteriorate the application. It is primarily the agitation of a washing machine, which deteriorates the Permethrin application as it knocks the molecules loose from the fabric. For best results, Sawyer recommends hand washing and air-drying. When using a conventional washer and dryer, use the gentle wash and dry cycles. Loss due to the dryer is limited compared to the detergent and washer agitation. Dry cleaning removes the Permethrin from the fabric.

Permethrin can last up to six weeks including through six weekly washings. All treatments are non-staining and not greasy. Always follow the directions for use on the package label.

    Orin, I got one bug bite on my entire Long Trail hike. I attribute this in large part to the Permethrin and the fact that I wore long pants and a long sleeved shirt for most of my hike. I just treated my clothes again today, in preparation for another 45 mile hike that I plan to take in Vermont next weekend.

  2. J Nagle July 7, 2009 at 12:13 pm #

    I have used permethrin on rare occassions to kill larval and nymph tick infestations upon my clothes while wearing

  3. J Nagle July 7, 2009 at 12:16 pm #

    Don't recommend this, permethrin, affects your nervous system with tingling sensation like your foot is asleep. Be Careful with this stuff, but it is a good precaution against ticks. Also very persistent lasts like fifteen washes through the laundry.

  4. Earlylite July 7, 2009 at 5:16 pm #

    Don't spray permethrin on clothes that you are wearing. You don't want to inhale it. But the stuff works – I just bought another bottle at REI this evening. We have been overrun this year by mosquitoes due to the high rainfall in New England in June, and I'm going to reapply it to my hiking clothes. It only lasts about 5 washes, by the way, if you spray it on your own stuff.

  5. antimosquito January 2, 2010 at 9:27 pm #

    how much is this bottle of permethrin?

  6. Earlylite January 3, 2010 at 2:24 pm #

    $15.50

  7. LGA May 22, 2010 at 7:43 am #

    This is available for about half that price on the llbean web site. Or run the product name thru froogle.com to find the price/amount combo that suits you.

  8. Helen W May 22, 2010 at 7:05 pm #

    Got my jug. I sure hope it works on ticks.

  9. Microzen May 23, 2010 at 6:18 am #

    Take a look at the EPA site on this product. I would wear a respirator and gloves when applying it.

    If you care about BPA-free bottles, then you will probably want to read about permethrin.

  10. pierre December 22, 2010 at 9:09 am #

    I got myself one of those. I need to treat my kit for a trip in Burma.

    I have the spray bottle as pictured above, but I was wondering if I could not just empty the bottle in a bucket and soak my clothes in there.

    you input is welcome :)

  11. sehsuan January 6, 2011 at 4:53 am #

    Pierre, we did that soaking methodology before I went for an outdoor field camp… surprisingly it works!

    But take note of the toxicity ESPECIALLY to cats and fish. And no, don't add this into your drinks…

  12. lostalot January 6, 2011 at 6:44 am #

    Check the concentrations of permethrin in the different products. It used to vary a lot and some required the consumer to dilute it with water.

  13. Earlylite January 6, 2011 at 6:47 am #

    You can use the Sawyer spray-on stuff they sell at REI right from the bottle with minimal contact to your hands. Just pull on thick plastic sandwich bag as a makeshift glove and spray away. I do it in the garage.

  14. David January 6, 2011 at 9:29 am #

    I checked the labels and got some Permethrin from Home Depot. I mixed it with water to the concentration on the Sawyer bottle and soaked my hiking clothes. Other than having to get custom sunglasses for that third eyeball now growing out of my forehead, I haven't noticed any effects on me from the treatment. I haven't been chewed up by bugs, either.

  15. lostalot January 6, 2011 at 10:02 am #

    Those eye-gnats are just going to love you now.

  16. dougb May 29, 2011 at 11:04 pm #

    You can get 10% permethrin and dilute it. It's sold by duravet and is safe for use on animals so that's the brand I use. Dilute 12-1 (to .83%)and soak your clothing in it for at least 3 hours and it's essentially permanent. It's the same method used by the U.S. Army for treating uniforms and it's a lot cheaper than the sawyer method. you can also spray it on, just make sure the garments or tent or mosquito nets or whatever are throroughly wet and put them in a plastic bag afterwards to make sure they stay wet for several hours. Then air dry. Army testing found this method lasts for at least 50 washings.

    • borneo diver March 28, 2012 at 5:43 pm #

      I liked your suggestion, so just checked the Duravet bottle of 10% permethrin and it said not for clothing–in fact said to remove clothes if you get this on it and contact poison control. Am I looking at the wrong stuff?? Thanks for your help

      • dougb June 4, 2012 at 5:05 am #

        It’s the same stuff, it will work, it’s just not registered with the epa for use on clothing so it cannot legally be used for that purpose. There currently is no product registered for use on clothing in this manner, it’s only available for military use. But if you’re not worried about black helicopters and such, it will work just the same. If you are worried about black helicopters, buy buzz-off treated clothing like ex-officio sells, it comes with permanent permethrin treatment.

    • Bruce September 30, 2012 at 10:59 pm #

      that is good information, thanks. I have sprayed it on in a ..05% (1/2 of 1 %) SOLUTION and it works incredibly well. I am so happy with it.

  17. pierre May 30, 2011 at 1:13 pm #

    thanks a lot for the solution dougb and others. I'll do just that when I return to Burma or others malaria zones. safe travels to you guys !

  18. Orin Keplinger May 30, 2011 at 2:38 pm #

    Hi, Pierre:

    You must be the spitting image of my neighbor’s dead son, Peter. He was an athletic child with lots of macho attitudes, as is his father. He, and my son loved to play in the woods, river, and fields near our home with their dogs.

    For several years, we had been treating our own family clothing with permethrin product as suggested by many sources. It is true that it is an effective mosquito repellant. BUT its main use for us, here in the United States – an almost, but not totally, malaria-free zone, has been to kill, not repel, the many ticks found to inhabit our north american woods and fields.

    Peter died two years ago of Lyme disease – usually transmitted by tick bites. Even our dogs picked up occasional ticks – just in our back yard.

    All the best, Pierre. I hope you and yours live long enough to visit malaria zones like Burma.

  19. Elizabeth June 18, 2011 at 2:24 pm #

    I'm traveling to Tanzania and trying to decide how much of my clothing to treat. Do you guys also sleep in permethrin-treated clothing? It makes me a bit nervous to wear chemicals 24 hours a day…

  20. Earlylite June 18, 2011 at 3:17 pm #

    If it bothers you don't do it, but I doubt it's really an issue. When I was in Tanzania, I took some sort of daily pill to prevent malaria and that worked fine.

  21. mom21 July 22, 2011 at 1:06 pm #

    I noticed in the photo that the gentleman was spraying his convertible hiking pants which is my intention as well. However, the bottle says not to use on synthetic fibers. Nylon is a synthetic fiber so I'm just trying to get confirmation from others that the spray won't eat through the pants. I have Northface convertible hikers. Leaving in 72 hrs and am a novice at this. I had to order the pants so if I mess it up I'm pretty much up the creek. Any advice would be much appreciated.

  22. Earlylite July 22, 2011 at 1:13 pm #

    That's me. I've been spraying Permethrin on synthetic hiking pants for years without any issues. It;s DEET mosquito repellent you want to avoid getting on plastic or gore-tex. Different substance entirely.

  23. mom21 July 22, 2011 at 1:21 pm #

    Thank you, sir:) I'm a novice trying to make a 40th b-day trip to Yellowstone. Keep hearing that there are a huge amount of bugs this year and I'm totally freaked. Just had the spray overnighted so we can use it on our hiking clothes and didn't want to destroy anything in the process. I do have another question, on the REI Jungle Juice and Ultrathon repellents they both say don't wear them under clothing. Really hadn't intended to since I'm going to spray the clothes but I'm curious as to why you shouldn't. Any thoughts?

  24. Earlylite July 22, 2011 at 2:10 pm #

    I really don't have a clue….anyone else know?

    My solution is to walk fast and stay covered up.

  25. untamed_wolf August 19, 2011 at 6:04 am #

    Jungle Juice is 98% DEET, so I'm thinking that they likely advise against wearing it under clothes and only on exposed skin because if a synthetic material comes in contact with it, it will begin to react.

  26. Judy Horowitz February 26, 2012 at 12:54 pm #

    Can I iron the clothes the clothes after they have been treated?

  27. Earlylite February 26, 2012 at 4:13 pm #

    I don’t know. I suggest you call REI customer service and ask.

  28. T Vilberg April 9, 2012 at 2:31 pm #

    I read that you want to dilute the 10% stuff down to 0.5% before use. Maybe that’s why the higher concentrations have that warning.

    Also, you can get the 10% concentrate WAY cheaper at a farm store. It’s in the horse-medicine area.

  29. J. M. Hayes April 30, 2012 at 12:55 pm #

    If I decide to soak the clothes in diluted Permethrin (0.5%) how do I dispose of the permethrin solution?

    • Earlylite May 1, 2012 at 9:05 pm #

      No idea. Suggest you read the directions on the box or call REI/Sawyer and ask.

    • dougb June 4, 2012 at 5:07 am #

      You don’t, you use only enough to soak the clothes and let them dry.

  30. Gentleman Antiquarian April 30, 2012 at 1:55 pm #

    When we went to Ecuador two years ago, my wife, son and I used Permethrin treatment on our clothes and we received very few bites even in the jungle. My son has recently returned from 10 weeks on the Osa Peninsula in Costa Rica and, again his Permethrin treated clothes worked a treat. We also slept uner Permethrin treated mosquito nets which seemed to repel most things apart from the cockroaches…

    Couldn’t recommend it highly enough

  31. Sati Houston June 3, 2012 at 11:08 pm #

    Is there any advice on whether the spray solution can be used to soak clothes rather than buying the soak solution? It seems that the soak solution is just diluted down to the 0.5% concentration (of the spray) and then the clothing is saturated with that 0.5% solution; saturation can just be done through soaking rather than spraying right? I’m on a time crunch, so if the spray solution can be used instead I’d love know. Thank you!

    • Earlylite June 3, 2012 at 11:09 pm #

      I’ve always just used the spray – works fine.

    • Sati Houston June 3, 2012 at 11:21 pm #

      Clarification: I’ll be spending 9 weeks in southeast asia, so (from all that I’ve read) the soaking method seems to last longer: 6 weeks instead of 2 weeks. I would rather soak my clothing now and not have to worry for a while rather than need to re-apply every 2 weeks.

  32. Grandpa June 4, 2012 at 12:21 am #

    I bought some pretty concentrated stuff from a local feed store and diluted it to .5%, put it in a bucket and soaked my clothes, tent, etc. I wore nitrile gloves, wrung it out and hung it up in the shop to dry and then stuck it in the dryer to finish up. I don’t have a long term durability report to give at this time. I just bought a hammock with mosquito net and will give it the soak treatment before we leave on a trip to New England, where I’m sure the skeeters, ticks, and black flies will give it a workout.

    • Onestep June 15, 2012 at 10:12 pm #

      Grandpa, I do the same as you. I buy an insecticide from K-Mart that has 100% permethrin as its only active ingredient and dilute it to 1/2%. Soak my clothes in it, hang ‘em to dry, good to go!

  33. Daywriter July 2, 2012 at 11:58 pm #

    answer to mom21 and Earlylite: Why does it say NOT to put Deet underclothes?

    Deet works by evaporation: the smell/Deet-a-cules hover over your skin in the evaporation process and discourage the bugs from biting. Undermeath your clothes — it just fumes next to/into your skin and does NOTHING as far as bugs are concerned. Since Deet does have some toxic or neurological effects on some samll %age of people (especially when used over long periods) it’s just safer and healthier not to use it where it won’t do any good anyway. Hence — USE ON EXPOSED SKIN ONLY.

  34. Trent Whittaker July 25, 2012 at 4:22 pm #

    When using the permethrin spray,
    do you spray both inside and outside
    the clothing?
    Thanks

    • Earlylite July 25, 2012 at 5:53 pm #

      I usually just spray the outside. Suppose you could do both – although it probably soaks through thinner fabrics anyway.

  35. Don Harmening September 7, 2012 at 6:46 pm #

    Does anyone know if heat from a clothes dryer can impair permethrin’s effectiveness? Thanks for any answers.

    • Earlylite September 10, 2012 at 2:50 pm #

      I haven’t had any issues, but I suggest you contact someone like Railriders which applies it to clothing and ask them.

    • lori December 1, 2012 at 8:42 pm #

      I think you were misled if anyone told you it was organic – I’ve never seen it labeled as such.

      I have not had issues, nor has anyone else I know, including my cat (tho I am careful to never apply it to anything while inside the house, she comes into contact with the treated, dry clothing frequently). It wears out after 6 – 8 washings and needs to be reapplied.

      Since you are not supposed to use it on live people using it on children probably won’t happen to anyone following the directions.

      I’ll keep using it. I think Lyme and other tick borne diseases are likely to cause permanent damage faster than the permethrin will, since I’m not sensitive to it (thank goodness, since it’s the only thing that keeps the ticks off reliably, they walk across DEET treated clothing). I dry my clothes in the dryer after washing treated clothing, but let it air dry when applying the treatment. It’s bonded to the fabric after it’s dried into the fibers.

  36. Chuck September 29, 2012 at 11:42 am #

    Used properly (e.g applied. dried completely (preferably OUTSIDE LINE dried) the active ingredient remains in cloth for multiple wash dry cycles.

    DO NOT GET THE SOLUTION ON LIVE ANIMALS OR PEOPLE. THE LIQUID IS TOXIC.

    Dried it attaches to the fabric and has few reported problems. Most problems come when people apply it to themselves, or clothing they are wearing.

    It’s mislabeled as a ‘repellant’ it is an insecticide which kills insects on contact.

    Avoid use around beneficial insects and food plants.

  37. Deb November 22, 2012 at 1:58 pm #

    You might want to get your facts right about the toxicity of pemethrin.

    Q. Is Permethrin dangerous to my skin?
    A. The warning labels on the cans or bottles are often misunderstood. Your skin metabolizes, or breaks down Permethrin within fifteen minutes of contact with skin. Therefore, it is of no value to you as a personal protection insect repellent when applied to the skin. In addition, the EPA precautionary statement, “Do Not Apply to Skin” indicates that Permethrin is ineffective when applied to skin; therefore, do not apply to skin.

  38. Jollygreen November 30, 2012 at 6:28 pm #

    Can this stuff be used to spray on furniture and carpets to kill and repel scabies? If so, what is your reccomendation on how to go about doing that? Thanks!

    • Earlylite December 1, 2012 at 12:26 pm #

      No idea, but I can’t see why not. It is toxic to cats, so beware. Perhaps you should try it on a sample of fabric and see.

      • tvilberg December 1, 2012 at 4:46 pm #

        It IS toxic to cats, but only when it is wet. Once it has dried they have no ill effects. Trust me, I treat a sheet with the stuff and let it dry completely. Then I put it over the covers on my bed on which my dog and cats sleep. None of the animals have shown ill effects (and two of the cats spend a great deal of their day on the sheet, sleeping on the down comforter. Last week, when I washed the treated sheet-cover, I discovered a tick — a very dead tick. So the stuff works, and has no effects on cats (or dogs and humans, for that matter) so long as it’s dry. One more thing. I’d dry it on plastic bags, not on a close line. A close line will allow some to drip off and you may as well have it all dry and attach to the fabric.

    • Norine March 21, 2014 at 2:40 pm #

      Our son got scabies from sleeping over at a friend’s (apparently dirty) house once. The doctor’s medicine I noticed was a permithrin cream. I had used permethrin from the feed store for my pig and compared the two. The feed store liquid was higher concentration–so I diluted it and treated the whole family with a spray down standing in the shower. Waited about 15 minutes and showered. I also used it, diluted with water, in a spray bottle on bedding, couches, cars, etc. to be sure everything was done at the same time. Worked for our family. Scabies were gone and nobody else got infected with them.

      • Norine March 21, 2014 at 2:42 pm #

        P.S. ~ This was also a MUCH cheaper way to treat it than paying for individual doctor appointments for each person in order to get the prescription.

      • Philip Werner March 21, 2014 at 2:42 pm #

        This isn’t for topical use on skin. Just clothing. You’re probably thinking of something else.

  39. Barrett December 1, 2012 at 6:52 pm #

    I have been using permetherin for two seasons now with no I’ll effects. Although I do not buy the stuff from the hiking stores. It is too expensive in that form. I buy it at mclendons hardware here in Washington. I can buy a bigger bottle for half the cost of the hiking brands. It is in the insecticide catagOry under bedbug killer. I travel to Central America and also hike/backpack. In trave I spray my luggage in and out plus most of my clothes. This way i keep unwanted travelers from coming home with me. I also spray my sleeping bag liner of which I sleep in on the bed of the hotels I stay at. Bedbugs, spiders,mosquitoes and other little biting critters are all part of the game when traveling and I have used this successfully in this approach.
    In hike/backpacking I spray all my clothes, sleeping bag, bag liner, tent and backpack with diet on my exposed skin areas. The permetherin on the tent is a source of entertainment in the evening as I watch bugs land on the mesh trying to get to me, then fall over and off the tent.
    The military has been using it for years and I know you can buy it at feed and tack stores for horses and other animal washings.. I do know it is not good for cats or fish in liquid form.
    Read the instructions, wear Gloves, have ventilation,dry thoroughly, life is better on the trail and abroad

    • Manny August 26, 2013 at 10:33 pm #

      Hey Barrett. Thanks for the information. I’m traveling to the Philippines. I always get eaten alive by mosquitos so I decided to be on the offensive for this trip. After reading up online about Permethrin, I took your advice and bought the product you recommended. Yes, it’s a lot cheaper. Do you dilute it before spraying? And did you have any problems with synthetic materials, like basketball/athletic shorts? How wet do you get the clothing? I’m traveling for a month so I can’t imagine my clothes will get washed more than once a week (4 washes). So, I’m thinking I’d be safe to do one wash at home, after spraying, to take care of any chemical build up. Any help you could provide would be awesome. Any other tips? I bought a respirator and some safety gloves.

      Thanks!

  40. Barrett December 1, 2012 at 7:56 pm #

    I don’t know about scabies, but Bonide sells it as a bedbug killer. On the back label it says it controls; bedbugs, lice, carpet beetles,flees, ticks,clothes moths, cockroaches,water bugs,palmetto bugs,millipedes, centipedes, sow bugs, pill bugs,ants,silverfish,firebrats, spiders, crickets, clover mites, cheese mites, granary weevils, rice weevils, confused flour beetles, rust red beetles, drugstore beetles,mealworms , grain mites and cadelles. I buy it at Mclendons hardware here in Washington, it is much cheaper than what you buy at the hiking stores(brick and mortar or internet )

  41. Grandpa December 1, 2012 at 9:44 pm #

    I was going to purchase a concentrated form online and then found out a local feed store had it, although at a slightly higher price than over the internet. I opted to spend my money locally and help out a pretty nice store owner. I know the few bucks I spent with him don’t make much of a difference in the long run but I also got personal attention and benefited from the knowledge of a wise and experienced man.

    I diluted the mixture to the concentration I wanted, and stuffed the clothes in a bucket with the mix and let them stew a few hours. I then hung them up over a plastic work table and squeegeed the runoff back into the bucket. The excess bucket contents got fed to the neighbor’s cat–NO! I put it into a plastic bottle and keep it stored for later use.

  42. Don Harmening December 1, 2012 at 11:28 pm #

    Well, I started this thread and I am so pleased to be learning so much about permethrin from so many people. I treated some socks today and had some extra left over so I re-treated some pants I had treated 2 months ago with it. I don’t think I can overdose my pants, can I?

  43. Walter Carrington June 9, 2013 at 11:39 am #

    Insect shield now will treat your clothing for $10/item, plus (I think) $10 shipping. This treatment lasts 70 washes, like the pretreated clothing. This would be more convenient for a long hike or trip.

    • Earlylite June 9, 2013 at 11:43 am #

      Cool! Expensive for small items, but this would be great for gaiters, pants, and shirts.

  44. Cherry Bomb June 10, 2013 at 7:38 am #

    Thanks for bringing this one out again, makes my job easier! After a 2010 section hike of the PCT, I got really sick, and then sicker. It turned out to be Lyme Disease. Since then, I have been giving Lyme Awareness talks at ADZPCTKO (yes, Lyme and other tick borne diseases are quite prevalent on the west coast!). I will add two things and I am not sure if they were covered in earlier comments, so I apologize if I am repeating information.

    First is toxicity: in wet form is it very toxic (to humans and pets. Once dried however, it is not. Sawyer has a great page explaining how Permethrin works on a more scientific (but for lay people) level. I am happy to link to that page once I find it later.

    Second is treating gear: so obviously I am a little gun-shy about ticks. I actually treat ALL my gear: tent, sleeping bag, pack, gaiters, clothes…I even treated my tyvek ground sheet, ha! So far, this has not affected my gear negatively.

    After going from lots of fun backpacking trips to needing a walker to get down the driveway in order to get the mail, I promote Permethrin like no tomorrow. Especially since we don’t see (or feel) all attached ticks.

    It truly is a safe incredibly effective product and in my opinion should be a part of everyone’s gear routine.

    • Jeff June 10, 2013 at 8:30 pm #

      Wow that sounds terrible. One major fear I have when backpacking is Lymes disease. Is it at a state where you will be using a walking your entire life? What’s the long term prognosis? Sorry to get off track but I live in Northern California and hike sections of the PCT often so this hits close to home for me.

        I fortunately have made progress after three years of intensive treatment (I had to have a port placed, home nurses, hospitals visits, etc). I no longer need my walker and am planning a hike of the PCT next year (2014) yay!. We are not sure if the brain damage is permanent, but it looks like it.

        Clearly, I’m very frank about my illness and the hell I went through for years. It is not to gain sympathy or pity but hopefully I can impart how important tick born disease awareness is here on the west coast. Nobody really considers it a real threat out here, but it actually is. Permethrin is such an easy and effective step!

        To further protect yourself, think like a tick. They crawl until they reach skin. They come from the ground, not falling out of trees like some think. So in addition to treating clothing and using DEET (I hate that stuff) make sure that the tick wont have an entry point -> tuck shirt into pants, pants into socks or gaiters, etc.. You will look like a huge dork but to me it’s worth it :-)

        I really recommend watching “Under our Skin” which is available on Netflix and Hulu. I know it’s been airing on PBS too.

        Here is a link to the risk map of California http://www.lymedisease.org/california/california_map.html

        http://www.lymedisease.org is a great resource in itself. I am currently working with a Board Member to train Dr’s that are near the trail to identify and properly treat TBD.

        Knowledge and awareness is power and with the proper precautions, you can have an awesome hike without fear of getting sick. :-)

    Soaking is a method of providing longer term treatment, as every fiber of cloth is saturated & treated. As the active ingredients wear off of the surface, the underlying fibers emit their reserve.

    Safe for prolong direct skin contact.

    I’ve been doing this for 30 years with no harmful effects (except my skin glows in the dark, I have no hair, my snot is Shrek green and i have a burning sensation when I urinate). JUST KIDDING!

    Hey Jollygreen! Did you ever find out if Permethrin spray worked to rid your house of scabies?
    I just bought some and am awaiting the results.

    Praying those buggers are dead!!

  49. windsurfgal June 25, 2013 at 2:02 pm #

    Samouel – can you give me a recipe for the soak? ie – 1 cup permethrin for ___ water.

    I’m going to do the soak method on my kid’s stuff for camp.

    Thanks

    The usual concentration I’ve seen is .5% permethrin. If you find 10% permethrin, you’d mix 1 part of permethrin to 20 parts water.

    You can google “permethrin 10%” and you will get multiple hits for quart size bottles that cost about the same as the Sawyer brand .5% and you get something 20 times more concentrated.

    I was about to order some online and then decided to check a local feed store that supplies items for horse owners. He had a quart in stock for about the same price as I could buy online.

    I mixed up about a half gallon (approx. 3 oz. of permethrin concentrate to two quarts of water), soaked my clothes in it until they were saturated, wrung them out back into the bucket (I used rubber gloves when doing this) and hung the clothes in the garage over a sheet of plastic. The excess that dripped off went back in the bucket later. When the clothes were pretty much dry, I tossed them in the dryer to finish the job.

    The excess permethrin went into some clearly labeled bottles for use later.

    Recently, we car camped with the grandkids in an area at prime tick season. I put some of the bottled permethrin into a hand sprayer and sprayed the ground around the entrance to the tent to try to keep them at bay.

  51. Grandpa June 25, 2013 at 2:45 pm #

    One small correction: .5% would be 1 part permethrin to 19 parts water, not 20. I doubt the difference would matter.

    • lisa July 4, 2013 at 11:20 am #

      Yeah, that gave me pause: wouldn’t .5% in half a gallon (64 oz) be .3 oz, not 3 oz? That’s almost 10X more.

      • Grandpa July 16, 2013 at 1:53 pm #

        .5% would be 3 oz. of the 10% permethrin solution. It’s true that there would only be a total of .3 oz. of actual permethrin in it. I was just giving the formula for mixing up about a half gallon of .5% solution starting from a 10% solution purchased at a feed store. Feed store… hmmmmm… feed this to the little biting bugs!

    Spent 10 years in Cameroon, West Africa. Nigeria and France make a pad treated with Permethrin that we set on lamps or other low (5-10 W) heat source to distribute it through the air in our bedrooms and other areas for evening times. Killed mosquitoes mostly. We have had no respiratory ailments or other toxicity results from this exposure. North America is crazy in their fear of these things just because a few people have overdone it in some cases. Am looking to make my own mosquito pads to try here in Canada.

  53. aps July 1, 2013 at 9:53 pm #

    permethrin is a chemical that naturally occurs in chrysanthemums it can now be chemically copied beware being over scared by the epa sites sayings as they tend to lean toward overkill on safety (not that this is a bad thing but you need to use a grain of salt) as a example of this next time you are in a garden center read the product label for neem oil (which is considered as organic) the label is printed w/ the requirements of the epa. it looks like this is a very dangerous chemical. however next time you are shopping for skin or nail care items even some shampoos look for the neem oil it is a prevalent ingredient in many quite good products as it is great for the skin as has been known for centuries. but the epa when classisfing it as a insecticide decided you need all but hasmat gear to apply what you just showered with just saying scare tactics are prevelant

  54. Kevin July 16, 2013 at 1:29 pm #

    Does anyone have an idea how long the treatment would remain effective if I treated, say, a tent, then dried it, then put it in storage for later use?

    Basically, what would be the “shelf-Life” of treated articles? I’ve seen a lot of responses regarding how many washes or how long out on the trail, but nothing yet on this.

    Thanks!

  55. lisa July 16, 2013 at 1:44 pm #

    Here’s a link to some VERY useful information, explains a lot about regulatory phrases, etc.

    From Cornell University’s extension program.
    http://pmep.cce.cornell.edu/profiles/extoxnet/metiram-propoxur/permethrin-ext.html

    Now I understand things like “do not apply to skin” which actually means, “don’t bother, it won’t help, your skin breaks it down in about 15 minutes anyway”.

  56. Hiker July 19, 2013 at 3:32 pm #

    I like to think that permethrin-treated clothing works, but when I soaked a piece of cotton fabric with it, I didn’t see any effect on insects or flies that contacted it (after it had dried). A spider 20 feet downwind died instantly while I was spraying though.

    • lisa July 19, 2013 at 4:32 pm #

      @Hiker, the length of time the insect is in contact with it matters (and, I’m sure, what particular species of insect).

      By the time a tick has landed on you and started crawling around to find a way in, it’s been minutes…the first time I treated my clothes with it I walked in brush ON PURPOSE to get ticks on me so I could watch. From shin-height, one started crawling up. By the time it got to my knee it was walking funny, then it just stumbled around in one place, and finally stopped moving. I’d say that was a total of less than 10 minutes.

      I just left it there and hiked for a while. It hung on, but when I poked it, it was dead and fell off.

      The link above from Cornell University about permethrin really explains things well.

    Thanks to all of you that posted above. Now that I understand a lot more about Permethrin. We live in Central Mass and deal with ticks every year . This will enable me to Treat clothes that I only use for feeding the wood stove with and that way can leave them in the garage away from our cat.

    • Ray May 30, 2014 at 8:19 pm #

      Just an FYI. . . I have been using “Sawyer Premium Insect Repellent 20% Picaridin” in pump spray 4 fl/oz as well as “Natrapel Insect Repellant 8 Hour Wipes” as an addendum to my Rail Riders Insect Shield clothing. BOTH of these products are applied directly to skin per instruction. Both work wonderfully here in the Florida panhandle/rainforest. I have experienced no negative effects from these products. I do find the wipes easier/neater to use than the spray however.

      • Ray May 30, 2014 at 8:24 pm #

        Should note the spray is only effective for 8 hours as well. Not as long lasting as Permethrin but can be applied directly to skin if needed.

    • ken w June 22, 2014 at 4:36 pm #

      Once treated and dry, clothes are no threat to cats, but do keep kitties away from the liquid and the spray mist. I’m in eastern MA and a co-worker contracted Lyme disease in Ipswitch, apparently a couple years ago and just got it diagnosed. It requires a heavy antibiotic regimen with no guarantee of success; much easier to avoid than treat!!

      • Paula Plett Dimattio June 23, 2014 at 7:52 am #

        Thanks for the heads up Ken. the number of Lyme disease cases are on the rise in the us as we venture outside more than ever before. Unfortunately sometimes the antibiotics aren’t enough to stop all of it. Read a great article in the May issue of prevention. Also on a rather sad note. most MD’s for along time ,don’t look for Lyme to start off with unless you walk in and tell them you have had a bite. A dear sweet friend had been bitten by ticks several years in a row , his house bordering the state forest in CT.Each time he went to the doctors, a barrage of tests followed and three months later was when the doctor checked him for it ,and then treated him. after that followed again the next few years with another bite, after bite, antibiotics ,and then Lyme took its toll on his body and he passed away last year.My own sister said no one dies from it , Well maybe this is an extreme case, but they do is the point and the better equipped you are not to get a bite from a tick the far better off you are .I
        am in central Ma. and we border Fort Deven’s which is all wooded . Our property is at the fence line so we have deer’s, bears’ and what ever wild animals coming through and a wood pile that ticks like to house in.

    Thanks for this article, it eased some of my concerns about using Permethrin. I just treated a couple sets of clothing and I have a question/possible issue regarding application:

    The sprayer that came with the bottle didn’t spray at all. Instead, it only emitted a heavy stream of liquid, which resulted in blotches of Permethrin on the clothing rather than an even application across all of the material. I assumed the sprayer nozzle would emit a mist rather than a stream. Is my experience normal? In order to coat all of the material I ended up using the entire bottle (24 Fl. Oz. Sawyer) on 2.5 outfits. I could not ‘lightly moisten’ the material with this particular sprayer.

    Please let me know if you think my application will be effective. I’m headed out on the Superior Hiking Trail in 48 hours and the bugs are going to be wicked. Thanks for any help!

    • paul g August 7, 2014 at 11:47 am #

      Just to follow up in case anyone else has the problem I did:

      I ended up buying another bottle of the Sawyer Permethrin, but it was the smaller 12 Fl. Oz. version. It came with a sprayer that could be set to either stream or mist. The 24 Fl. Oz. bottle didn’t have this option, only stream. Anyway, I misted the remainder of my clothing/gear. It was much easier and I feel better about the application this time around.

      Thanks again to the author and to all who have commented here.

    Another use I’ve heard of is to soak cotton wadding with permethrin, stuff it in toilet paper tubes, and scatter them in dry places around a tick infested area. Mice will find the cotton and take it to line their nests. Your local mice then become instant exterminators, reducing the local tick population for you.

  60. Dale Hughes September 5, 2014 at 12:30 am #

    The cheapest way to buy this stuff is on Amazon. I bought a bottle of Permethrin 32 that dilutes to 80 gallons of .5% solution.
    I soak all my hiking clothes and haven’t had any tick issues since. Buying the super diluted Sawyer products are way too expensive for what you get.
