Permethrin is an insecticide used to treat clothing, gear, and certain surfaces. When used exactly as the product label directs, exposure can be limited.

• Follow the label: Each product has specific directions and safety statements.
• Avoid skin contact: Don’t apply clothing treatments directly to skin.
• Apply with ventilation: Use outdoors or in a well‑ventilated area and avoid breathing spray.
• Let it dry: Keep people and pets away until treated items are fully dry.
• Handle carefully: Wear gloves if recommended and wash hands after use.
• If there’s accidental exposure: Follow first‑aid guidance on the label and consider contacting a medical professional with questions.

Sensitivity can vary by person, so choosing and using products as directed is important.

Most permethrin sprays on this page are formulated to treat fabrics and gear, not bare skin.

• For fabrics: Treat outerwear, socks, packs, tents, and similar items as directed, then let them dry completely.
• Not for direct skin use: Clothing treatments aren’t intended to be sprayed on skin.
• Using a skin repellent: If you want something for exposed skin, choose a repellent specifically labeled for skin use and follow that label’s directions.
• Read before you buy: Product titles and labels indicate whether they’re for clothing/gear, premises, or animals. Pick the category that matches your need.

Always review the label to confirm the intended use and any precautions before applying.

Application steps can vary by product, but these general tips can help:

1. Check the label: Confirm it’s for clothing/gear and note dry times.
2. Work in fresh air: Apply outdoors or in a well‑ventilated space.
3. Prep items: Hang or lay garments and gear clean and dry.
4. Spray lightly: Apply to outer surfaces until damp, not dripping. Focus on cuffs, socks, and lower legs as directed.
5. Avoid contact: Don’t spray while wearing the clothes; avoid skin and breathing mist.
6. Let it dry: Keep items undisturbed until fully dry before wearing or packing.
7. Aftercare: Wash hands and store the product safely; re-treat only as the label recommends.

Results can vary based on item materials and conditions.

It depends on the product type. Clothing and gear treatments are typically best applied outdoors or in a very well‑ventilated area.

• Clothing/gear sprays: Treat items outside when possible, avoid wind, and let everything dry fully.
• Premise or yard products: Some concentrates and ready‑to‑use sprays are labeled for indoor and/or outdoor surfaces. Only use them where the label allows.
• Protect people and pets: Keep others away from the area during application and until treated surfaces are dry.
• Prep the space: Cover nearby items you don’t want treated and avoid spraying near food prep areas.

Always follow the label for allowed locations, ventilation needs, and re‑entry guidance.

Yes—formulations and directions vary by use case.

• Clothing & gear treatments: Ready‑to‑use sprays designed to bond to fabrics and equipment. Applied to items off‑body and allowed to dry.
• Premise/yard treatments: Concentrates or ready‑to‑use sprays for lawns, building exteriors, or indoor surfaces as labeled. Dilution and application tools may differ.
• Animal/livestock products: Some items are labeled for use on or around animals; only use as specified.
• Choosing on Walmart.com: Filter by category (e.g., clothing and gear, insect sprays and foggers, or outdoor concentrates) and read the product label to match your need.

Select the formulation intended for your application and follow all directions for safe, effective use.
