What is it?
IR3535 is an active ingredient in personal insect repellents. CDC lists it among ingredients to look for in EPA-registered mosquito repellents.
Where does it fit?
Repellents help prevent bites. They do not eliminate larval habitats or treat an infestation in a home or yard. Protection claims, permitted pests and duration depend on the exact product label.
What cautions matter?
Follow the product label for age restrictions, application sites and reapplication. Keep repellent out of eyes and mouths and off cuts or irritated skin. Natural origin does not establish that a product is harmless. Do not use a human repellent as a pet treatment or household pesticide. Permethrin clothing treatments are a different use category and are not for direct use on skin.
What governs use?
The current product label controls permitted pests, sites, placement, protective equipment and restrictions. This is an educational ingredient reference, not a recipe, product endorsement or statement of Texas registration.
