Which pesticide classification is primarily used to control insects?

Insecticides are specifically designed to target and control insect populations. They work through various modes of action, such as disrupting the nervous system of insects, affecting their growth and development, or interfering with their reproductive capabilities. The primary purpose of insecticides is to reduce pest populations that can harm crops, structures, or human health.

Fungicides, on the other hand, are formulated to fight fungal diseases, while herbicides are intended to control unwanted plants or weeds. Bactericides are used to eliminate bacteria that can cause disease in plants or animals. Each of these classifications targets different types of pests, which is why insecticides are the appropriate choice for controlling insects specifically.
