DIY Permethrin Spray: How to Treat Your Own Clothes

🎯 Key Fact: You already own regular outdoor gear—hiking boots, pants, jackets. These don't have factory permethrin treatment. But they can.

With a permethrin spray, you can treat your existing clothes to provide tick protection comparable to specialty permethrin-treated apparel. This guide shows you exactly how to DIY-treat your clothes, plus answers to common questions about safety and effectiveness.

Why Treat Your Own Clothes?

Cost-effective: Treat existing clothes instead of buying new ones
Versatile: Apply to any fabric—jeans, hiking pants, boots, hats, even backpacks
Effective: Same active ingredient as factory-treated clothing
Flexible: Treat clothes seasonally as needed

How Permethrin Spray Works

Permethrin spray works exactly like factory treatment. When sprayed on fabrics, it dries and bonds to the fibers. It kills ticks on contact and lasts through multiple washings (typically 5-6 washings depending on the product).

Step-by-Step: How to Treat Clothes with Permethrin

What You'll Need

Permethrin spray (Sawyer or similar brand)
Outdoor space (garage, deck, yard)
Clothes or gear to treat
Hanger or laid flat
30 minutes drying time

Step 1: Choose Your Location

Spray outside—garage, deck, or yard. You want good ventilation. Do not spray indoors.

Step 2: Hang or Lay Out Clothes

Hang items on a hanger or lay flat on a table. Make sure all surfaces are accessible.

Step 3: Spray Evenly

Following the bottle instructions, spray until the fabric is slightly wet but not soaking. Cover:

Pants legs and waistband
Shirt sleeves and front/back
Socks and shoe uppers
Hat brims and band

Step 4: Let Dry Completely

Wait at least 4-6 hours (preferably overnight) before wearing. Full effectiveness requires drying time.

Step 5: Wait Before Washing

Don't wash treated clothes for at least 24 hours. This allows the permethrin to fully bond to the fibers.

            💡 Pro Tip: Treat clothes the day before a hiking trip. That way they're dry and ready when you head out.
        

Safety: Is Permethrin Spray Safe?

For Humans

EPA-registered and safe when used as directed
Breaks down on human skin
Does not absorb through treated clothing
Safe to wear treated clothing against your skin once dry

For Pets

Safe for treated clothing around pets
Do not spray directly on animals
Let clothes dry completely before allowing pets near them
Some pets (especially cats) are more sensitive—use caution

Storage and Handling

Keep out of reach of children and pets
Store in cool, dry place
Don't inhale fumes—spray outdoors
Wash hands after applying

⚠️ Important: Never spray permethrin directly on your skin or as a body repellent. It's designed for fabric, not skin. Use skin repellents (Picaridan, DEET) on exposed skin instead.

Best Products to Treat

Socks: Very important (ticks crawl up)
Boots: Important for ankle protection
Hats and caps: Good idea for head/neck protection
Backpack exterior: Helpful as additional barrier
