Insecticide is an agent that kills pests, such as beetles, flies, cockroaches, larvae, hoppers, and nearly 10,000 other pests. The use of insecticides has gone through several stages: the first to discover natural insecticides and inorganic compounds, but they have a single effect, a large amount, a short duration; organic synthesis of organochlorine, organophosphorus and carbamate.
Insecticides, which are characterized by high-efficiency, high-residue or low-residue, many of which have high acute toxicity to mammals.
