EPA evaluation and regulation of pet flea-and-tick collar products (risk assessment, 15-year review, enhanced incident/sales reporting)

The US EPA evaluates pet collar products that protect pets from fleas and ticks. As with other topical pesticide products, Before a pet collar product is registered, EPA conducts a human health risk assessment and an ecological risk assessment, and EPA also reviews companion animal safety data to determine potential harm to the treated animal.

Registered active ingredients are kept current: EPA reviews the active ingredients used in pet collars at least every 15 years (the registration-review program; see epa_reg_flea_tick_products for the shared EPA/FDA oversight split and the February 2023 joint whitepaper on transferring oversight of flea-and-tick pet products from EPA to FDA).

For collar products specifically, EPA aims to improve the quality of pet collar incident reporting data and sales data it receives from pesticide registrants. Enhanced reporting requirements for pet collars would align with requirements for most spot-on products, letting the Agency review pet incidents across the most-used registered pet products and decide whether registration or label changes are needed. As EPA re-evaluates collar active ingredients, it is considering efficient ways for registrants to provide these data and the analyses that could expedite the Agency's assessment.
