![]() ExOfficio Baja Shirt with Insect Shield |
Insect Shield technology converts clothing and gear into convenient, effective insect protection.
Insect Shield products are proven to repel mosquitoes, ticks, ants, flies, chiggers and midges (no-see-ums).
The Insect Shield Protective Barrier
Insect Shield Repellent Apparel and Gear is the most effective new tool in over 50 years in the battle against insects and insect-borne disease—a completely new way to protect against annoying and potentially dangerous insects. With its odorless and invisible insect protection, the only way to tell it’s there is that the bugs aren’t biting.
The built-in insect repellent provides a carefree outdoor experience, letting you focus on your adventures—not the bugs.
The Insect Shield Advantage
EPA Registered
Insect Shield is registered by the Environmental Protection Agency. The EPA registration process is designed to evaluate a proposed product to ensure it will not have adverse effects on humans or the environment. Insect Shield has been evaluated at multiple levels—the chemistry, the application process and the final consumer product. The end result was Insect Shield receiving the first-ever EPA registrations for insect-repellent clothing and gear.
Effective
Insect Shield products are proven to repel numerous varieties and species of mosquitoes, ticks, ants, flies, chiggers and midges (no-see-ums). This includes insects with the potential to carry dangerous diseases such as Malaria, West Nile virus, Dengue fever and Lyme disease.
Tested and Proven
Insect Shield technology is the result of years of research and field study. Numerous studies have confirmed the effectiveness of permethrin-treated clothing as an insect repellent. Insect Shield’s own testing methods follow USDA guidelines, and the results prove our unique, long-lasting properties.
Convenient
Insect Shield’s protection is invisible, odorless and as easy as putting on your clothes. Unlike traditional repellents, Insect Shield products cannot be misused or over applied and do not require re-application.
Comfortable
Insect Shield has no unpleasant smell or feel. The active ingredient, permethrin, is a man-made version of a natural insect repellent found in certain chrysanthemums. It is bonded to the fibers using Insect Shield’s patent-pending process that transforms ordinary clothing into comfortable insect protection for the whole family.
Durable
The repellency of Insect Shield is EPA registered to last through 70 launderings which is more than double the average life expectancy of a garment as listed by the International Fabricare Institute. This is also well beyond the life of most performance finishes commonly used in the technical-apparel industry.
Easy Care
Normal home laundering is recommended. Insect Shield products can be bleached, starched, pressed, etc., without effect on the repellent quality; however, they should not be dry cleaned because that removes the active ingredient.
Tested for Effectiveness and Durability

Positive Impact on World Health
One of the founders’ original intentions for developing Insect Shield was to help protect children from insect-borne diseases. We at Insect Shield realize the potential to greatly impact worldwide health and continue to support many global initiatives. Permethrin-treated clothing is now recommended by the following international agencies:
