Malathion is a pesticide that is widely used in agriculture, residential landscaping, public recreation areas, and in public health pest control programs such as mosquito eradication. it is the most commonly used organophosphate insecticide.

Malathion kills insects by preventing their nervous system from working properly. When healthy nerves send signals to each other, a special chemical messenger travels from one nerve to another to continue the message. The nerve signal stops when an enzyme is released into the space between the nerves. Malathion binds to the enzyme and prevents the nerve signal from stopping. This causes the nerves to signal each other without stopping. The constant nerve signals make it so the insects can't move or breathe normally and they die.

Except for agricultural production, malathion is often used: 1) by home gardeners for outdoor residential uses including vegetable gardens, fruit trees, and a variety of ornamentals; 2) in public health pest control programs for controlling mosquito-borne illnesses.
