Yes, flumethrin is a pesticide. It belongs to a class of insect repellents called pyrethroids and is used to kill and repel insects in agricultural and residential settings.
Flumethrin works by disrupting the normal functioning of an insect’s nerve cells, causing paralysis or death. It can be applied topically directly onto the skin or clothes, or it can be used as a fogger or spray indoors or outdoors. It is most commonly used to control fleas, ticks and bed bugs in homes, as well as on farms for agricultural pest control. Additionally, flumethrin may also be combined with other active ingredients for use against mosquitoes and other flying insects.
