The Spraying Procedure:
1. Find a well ventilated shady spot away from kids, animals, food and water supplies.
2. I recommend wearing protective gloves any time you’re handling chemicals and a mask is understood as optional, but I recommend wearing one especially while spraying. When you can avoid breathing in chemicals, you should.
3. Hang all of your items inside out (or with camping gear, spray the inside first) Hold the bottle 6-8 inches away and spray the entire surface area paying close attention to cuffs and seams and areas that fit tighter against your skin (the buggos favorite spot.)
4. Flip right side out and spray the entire surface area again paying close attention to cuffs and seams. (or with camping gear, spray the outside paying close attention to any portion that will make contact with the ground or a tree)
5. Leave to dry in a shaded area.
6. Once everything is completely dry it is ready for use! No need to wash or dry the items directly after the treatment.
7. Repeat in 6 weeks or after 6 washings.
Your treatment will break down quicker in the machine washer and dryer with regular strength detergents. If you need to wash your clothes it's best to hand wash your items with a small amount of baby Dreft detergent or sensitive/gentle laundry detergent and hang to dry.
Oxygen and sunlight also break down the Permethrin treatment quickly. To extend the life of your treatment, store everything in airtight bags/storage in a dark room or closet in between uses.
When it comes to camping gear, remember to treat anything that will make direct contact with the ground or trees. Lines and suspension are great roadways for little critters.
3. Send Away
Insect Shield is a company that will treat your clothing for you. Insect Shield developed a proprietary Permethrin treatment process that will last up to 70 washings vs. 6 washings if you treat your items yourself.
This is a popular choice if you want a hands off approach and do not mind spending the money and waiting the extra time the send away process takes. No mess, no hassle, no measuring or mixing or taking your own time.
If you choose this route, you can get started with this Insect Shield order form. The prices are listed on the form.
Insect Shield will not typically treat any clothing that reads “dry clean only”, “do not tumble dry”, “hang to dry”, or “water resistant”.
- The send away treatment forms are for clothing only. (You may be able to work out something with them for treating your gear. But that would be handled in correspondence between you and them)
- They sell spray bottles as well.
There are many companies that sell Permethrin treated clothing. You can find them on Amazon, outdoor recreation stores, and InsectShield.com. This is a great option if you are already in the market for new hiking/camping clothes. Just keep in mind that eventually these will need to be re-treated.
How to Dispose of Permethrin After Treatment
🚫 Never pour Permethrin down the drain. It is harmful to the environment and deadly to fish.
🚫 Don't pour it back into the original solution, better to keep that pure.
👍 You can pour excess solution into a clean, empty plastic jug or bottle to save for next time. Just make sure the jug or bottle is properly labeled, tightly sealed, and stored in a safe, cool, dry place.
👍 If you must dispose of it, it is best to leave it open/uncovered in a safe, ventilated, or sunny spot to evaporate on its own before throwing away. This also goes for the bags and buckets you’ve used. It is best to let them air dry after use rather than rising the left over Permethrin with water.
🚫 Never leave evaporating Permethrin in an area accessible to children or animals.
