What Is Bifenthrin?
Bifenthrin is a synthetic pyrethroid insecticide widely used in professional and consumer pest control products. It works by disrupting the nervous system of insects, causing paralysis and death. It's effective against a broad range of pests including cockroaches, ants, spiders, and termites.
Is Bifenthrin Safe for Humans?
Bifenthrin is classified as a possible human carcinogen (Group C) by the US EPA. At typical household application levels, acute toxicity to humans is low. However:
- It is a skin and eye irritant — direct contact requires washing immediately
- Inhalation during application can cause respiratory irritation
- Residues persist on surfaces for weeks to months
- Children and pets are at higher risk due to surface contact and lower body weight
Most manufacturers recommend vacating treated areas for several hours after application and ventilating thoroughly.
Is Bifenthrin Safe for Pets?
Bifenthrin is highly toxic to cats — cats lack the liver enzyme to metabolize pyrethroids and can suffer severe neurological effects from even small exposures. It is also toxic to fish and aquatic organisms. Dogs are more tolerant but can still be affected by large exposures.
