Natural insecticides are substances derived from natural sources, such as plants, minerals, or microorganisms, that help control pest populations. Unlike synthetic chemicals, these insecticides are often considered safer for humans, pets, and the environment. Common examples include neem oil, pyrethrin from chrysanthemum flowers, and diatomaceous earth, which disrupts the exoskeletons of insects. These products work through various mechanisms, such as repelling pests, disrupting their life cycles, or causing physical harm. Many gardeners and farmers prefer natural insecticides for sustainable agriculture, as they can effectively manage pests while minimizing chemical exposure and promoting ecological balance.
