The low odor and non-corrosive formula of CSI 4-4, a synthetic pyrethroid vector control insecticide, is effective against adult mosquitoes, flies and gnats. The formula contains 4.6% permethrin, which attacks the nervous system, and 4.6% piperonyl butoxide, a synergist, gives CSI 4-4 its quick knockdown power. CSI 4-4 also controls other biting and non-biting, flying insects. Designed for ultra low-volume (ULV) and thermal fogging applications, the product is available in 2.5-gal. containers and 55-gal. drums.
