What is a common synthetic insecticide used in mosquito control?

Permethrin is a widely used synthetic insecticide specifically noted for its effectiveness in mosquito control. It belongs to the pyrethroid class, which are designed to mimic the natural insecticidal properties of pyrethrins derived from chrysanthemum flowers. Permethrin works by attacking the nervous system of insects, leading to paralysis and death. Its use in various applications, such as mosquito control in outdoor settings and for treating clothing and gear to repel and kill mosquitoes, highlights its practicality and effectiveness.

The focus on synthetic insecticides in mosquito control has become essential due to their prolonged efficacy and ability to target specific pests with less environmental impact compared to some older chemicals. Permethrin is favored for its residual activity and is often formulated into sprays, fogs, and other treatments.

While pyrethrin is a naturally occurring compound, permethrin is synthetically produced and thus distinct in its application and effectiveness. Malathion and chlorpyrifos, though also used in pest control, have different modes of action and safety profiles that may make them less preferred for mosquito-specific control.
