Insecticides can be classified into two categories:
- Contact insecticides - Have no residual activity
- Systematic insecticides - Have long-term or residual activity
Moreover, an insecticide can be organic, inorganic, or natural. Organic insecticides contain organic chemical compounds and normally act upon contact. Inorganic insecticides contain metals. Natural insecticides such as neem, pyrethrum, and nicotine are made by plants as defense mechanisms against insects.
An insecticide can be packaged in various forms such as baits, sprays, or slow-release diffusion.
Because of their toxic properties, insecticides can pose a great danger to non-target insects, pets, people, and the environment. Nearly all insecticides have a potential to considerably alter ecosystems and some concentrate along the food chain.
