How are pheromones used to control insect pests?

By serving as bait by which the affected insects are trapped is the way in which pheromones can be used as insecticides. Insecticides are used to control insect populations. Pheromones are excretions or secretions by which insects of a certain kind communicate information to other members of that same kind. The information may range from threats, sexual rendezvous, mass meeting places and times, food trails, and more. So for example, a pheromone may be released to guide insects to what they think will be willing food sources. Instead, it leaves them in a sticky trap.
