To further its understanding of the issue, the EPA required enhanced reporting for the year 2008 from all manufacturers of EPA registered topical pesticide products, which encompassed all classes of pesticide active ingredients,
including cyphenothrin, phenothrin, permethrin, imidacloprid, dinotefuran, fipronil, amitraz, etofenprox, S - methoprene, pyriproxyfen, and metaflumizone.
Additionally, a fipronil treatment may
include the fleas killing products of permethrin, as in Effitix, or
cyphenothrin as in Frontline Tritak for dogs.
