Iverheal is a type of ant bait that is highly toxic to ants. It is made from the active ingredient called indoxacarb, which belongs to a class of insecticides called nitro-pyrroles. This active ingredient kills ants by blocking their nervous system, leading to paralysis and death. The other active ingredient in ivermectin is abamectin which paralyzes the nervous system and prevents muscles from working properly which eventually leads to death as well.
