Does permethrin ruin clothing?

Permethrin is a commonly used insect repellent and insecticide that provides effective protection against a wide range of pests. It is widely used to treat clothing and equipment for outdoor activities such as camping, hiking, and fishing. One common concern among users is whether permethrin can damage clothing. In this blog post, we will delve into this question and explore the effects of permethrin on clothing and other materials.

Permethrin and its effects on clothing

Contrary to popular belief, permethrin does not damage clothes or equipment. Unlike DEET, which may harm some fabrics and materials, permethrin is compatible for use even on fragile fabrics such as silk, as well as all synthetics and waterproof membrane fabrics. This makes it a versatile choice for treating various types of clothing.

When properly applied, permethrin bonds to the fibers of the fabric, creating a protective barrier that repels insects. This barrier does not affect the appearance or texture of the clothing in any way.

Compatibility with various fabrics

Permethrin is compatible with a wide range of fabrics, providing effective protection without compromising the integrity of the material. Here are some examples:


Silk is a delicate fabric that requires special care. Fortunately, permethrin is safe to use on silk without causing any damage or discoloration.

Synthetic materials

Synthetic materials like polyester, nylon, and spandex are commonly used in outdoor clothing due to their durability and moisture-wicking properties. Permethrin can be applied to these fabrics without any adverse effects.

Waterproof membrane fabrics

Waterproof membrane fabrics, such as Gore-Tex and eVent, are commonly used in outdoor jackets and pants to provide protection against rain while allowing breathability. Permethrin does not compromise the functionality of these fabrics, allowing users to enjoy both insect protection and weather resistance.

Permethrin and its effects on other materials

In addition to clothing, permethrin is also compatible with other materials commonly found in outdoor equipment.

Compatibility with plastics

Plastic materials, such as zippers and buckles on backpacks and camping gear, are not affected by permethrin. Users can treat their gear without worrying about any damage to these components.

Compatibility with finishes

Permethrin does not interact with or ruin surface finishes, such as water repellent finishes or DWR (Durable Water Repellent) coatings, on outdoor clothing or equipment. It can be safely used on treated items without compromising their functionality.

Benefits of using permethrin on clothing

Now that we understand that permethrin does not damage clothing or equipment, let’s explore the benefits of using permethrin-treated clothing:

1. Protection against insects

The primary reason for treating clothing with permethrin is to provide effective protection against insects, including mosquitoes, ticks, fleas, and ants. Permethrin repels these pests, reducing the risk of bites and potential transmission of diseases such as Lyme disease and malaria.

2. Extended lifespan of clothing

By repelling insects, permethrin-treated clothing reduces the likelihood of damage caused by bug bites and stains. This can significantly extend the lifespan of outdoor clothing, saving you money in the long run.

3. Versatility for different outdoor activities

Whether you’re hiking in the woods, fishing by the lake, or camping in the wilderness, permethrin-treated clothing provides a versatile solution for insect protection. You can wear the same clothing for various outdoor activities without the need for additional insect repellents.

Proper application of permethrin on clothing

To ensure maximum effectiveness and safety, it is important to follow the proper application process when treating clothing with permethrin:

1. Follow manufacturer’s instructions

Always read and follow the instructions provided by the manufacturer of the permethrin product. Each product may have specific guidelines for application and drying time.

2. Wear protective gloves and clothing during application

When applying permethrin, it is advisable to wear protective gloves and clothing to minimize direct contact with the skin. This is a precautionary measure, as permethrin is generally safe for use on clothing.

3. Allow sufficient drying time

After treating the clothing with permethrin, it is important to allow sufficient drying time before wearing or storing the items. This ensures that the permethrin has bonded properly to the fabric and is fully effective.

Safety considerations when using permethrin on clothing

While permethrin is generally safe for use on clothing, it is important to take some precautions to minimize the risk of exposure:

1. Avoid direct contact with skin

Although permethrin is safe to use on clothing, it is best to avoid direct contact with the skin. This can be achieved by wearing long sleeves, pants, and footwear for added protection.

2. Keep away from eyes, mouth, and nose

When using permethrin-treated clothing, be cautious not to touch your eyes, mouth, or nose with your hands or clothing. Wash your hands thoroughly after handling permethrin-treated items.

3. Store permethrin-treated clothing properly to prevent exposure

When not in use, store permethrin-treated clothing in a sealed plastic bag to prevent potential exposure to children or pets. This will ensure that the treated clothing remains effective while reducing the risk of accidental contact.


Permethrin is a highly effective insect repellent and insecticide that poses no harm to clothing or equipment. When properly applied, permethrin does not damage or affect the appearance or functionality of clothing materials such as silk, synthetic fabrics, or waterproof membrane fabrics. It is also compatible with plastics and finishes commonly found in outdoor gear. By treating clothing with permethrin, users can enjoy the benefits of enhanced insect protection, extended clothing lifespan, and versatility for different outdoor activities. Taking proper precautions and following manufacturer guidelines ensure safe and effective use of permethrin-treated clothing.
