  • Q: ViewWill Permethrin ruin my clothes or equipment?

    No. Permethrin will 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, plus all synthetics and waterproof membrane fabrics. Permethrin will not affect plastics or finishes. IF IN DOUBT, try a sample on an obscure surface area, especially on delicates and check it after 24 hours of exposure.

    Sawyer® Permethrin Insect Repellent is odorless, non-greasy and non-staining after it dries. Permethrin can be harmful to aquatic creatures such as fish, so do not spray Permethrin around fish aquariums.

  • Q: ViewIs Permethrin dangerous to my skin?

    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.

  • Q: ViewHow harmful are Permethrin fumes while treating clothing?

    It is recommended that treating clothing with the permethrin aerosol be performed outdoors. If the treatment is accidentally carried out indoors, no adverse health effects are expected based upon calculations of inhaled dose. However, individuals with breathing problems, such as asthma, may be at greater risk. The odor arising from treating fabric with permethrin is mostly from the aerosol propellants rather than from the insect repellent itself.

  • Q: ViewCan I use Permethrin on my cat or dog?

    Sawyer Permethrin can be used on dogs but is toxic around cats until it has dried. Permethrin can last up to two weeks on your dog depending on the hair type and length.
