Bifenthrin is a pyrethroid insecticide that affects the nervous system of insects. Products containing bifenthrin include Talstar, Capture, Brigade, Bifenthrine, and Ortho Home Defense Max.

The Bifenthrin Molecule was discovered and developed by FMC Corporation Pty Ltd it: Is a 4th generation pyrethroid insecticide. Is insoluble in water. Is non-volatile Is immobile in the soil. Has the longest residual of any currently registered termiticide product.

The material safety data sheet (MSDS) for FMC Corp.'s Biflex (Bifenthrin's trade name) shows carcinogenic qualities to be virtually zero. It is highly toxic to fish, since it, like most pyrethroids, is also an ATPase inhibitor. Aquatic vertebrates are much more sensitive to ATPase inhibitors than terrestrial vertebrates due to their high dependence on ATP synthesis in the gills to maintain osmotic balance.

The United States Environmental Protection Agency (EPA) once classified bifenthrin in the past as a class C, although it no longer does so. It is probable that a one-time class "C" carcinogen (possible human carcinogen)designation was based on older data and lack of studies.

Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general population, and to infants and children from aggregate exposure to bifenthrin residues.

Based on the above findings, the "class C Carcinogen" designation was likely pre-2002, the date of this document.

Bifenthrins do have possible health impacts, however, and these should be understood.
