The Insect Shield bug repellent technology we use converts clothing and gear into long-lasting, effective, and convenient insect protection. Insect Shield technology repels fleas, ticks, flies, and other insects. Repels insects including those that can carry Zika virus, Lyme disease, West Nile virus, malaria and others.  

The active ingredient in Insect Shield, permethrin, is so tightly bonded to the fabric fibers that it retains effective protection through the expected life of the product. Permethrin is in the pyrethroid family. Pyrethroids are synthetic copies of natural extracts found in plants such as the chrysanthemum flower. 

Insect Shield is registered by the Environmental Protection Agency (EPA). The EPA registration process is designed to evaluate a proposed product to ensure it is effective and will not have adverse effects on people or the environment. Insect Shield products have been rigorously evaluated on multiple levels: the chemistry, the application process and the final consumer product.
