What is the primary purpose of using insecticides?

The primary purpose of using insecticides is specifically to target and kill insects that may be harmful to crops, structures, or human health. Insecticides contain active ingredients formulated to interfere with the vital processes of insects, leading to their death. This includes disrupting their nervous system or inhibiting their ability to feed, breed, or develop.

Other substances aimed at different organisms have distinct classifications and purposes. Herbicides, for example, are designed to kill weeds, while fungicides target fungal infections. Repellents are formulated to deter animals but do not necessarily kill them. Therefore, the use of insecticides is clearly focused on managing insect populations effectively, differentiating them from products intended for other types of pests or plants.
