Where It Comes From
Synthetic repellent active used in some sprays, treated gear, outdoor area products, and flea/tick pet collars [1][2].
How You Are Exposed
Skin contact when applying, breathing mists indoors/outdoors, touching treated pets or gear, and workplace handling [1][2].
Why It Matters
Can cause mild skin/eye irritation; overall acute toxicity is low in studies. Human long‑term data are limited, and there are no major cancer classifications [1][2].
Who Is at Risk
Workers and frequent users; young children who touch treated items and mouth hands; people with sensitive skin [1][3].
How to Lower Your Exposure
Use EPA‑registered products as directed; apply with ventilation; avoid eyes and broken skin; wash hands/skin after use; for pet collars, fit and handle per label and keep infants from chewing/handling; store out of reach [1][3].
