- Actellex 500 EC is an organophosphate insecticide containing pirimiphos-methyl 50% (w/v). It acts by contact and ingestion, inhibiting the cholinesterase enzyme in the insect nervous system, which leads to paralysis and death. It works fast and is effective against flying insects such as flies and mosquitoes, and is also used efficiently to control mosquito larvae in stagnant water. It is one of the strong products in public health programmes when used correctly, giving effective results when the product is spread evenly over the target surfaces or water; its success depends largely on accurately locating the infestation and correct application.
