ActivityThe products containing bifenthrin are effective in controlling over 75 different pests including spiders, mosquitoes, cockroaches, ticks and fleas, pillbugs, chinch bugs, earwigs, millipedes, and termites. Like many other insecticides, bifenthrin manages insects by paralyzing the central nervous system upon contact and ingestion.
