How Do Mosquito Coils Work?

Mosquito coils work in one of two ways to help get rid of mosquitoes. Coils that contain insecticides will kill mosquitoes, while those that contain aromatic substances, like citronella, will repel mosquitoes or reduce the likelihood that they’ll bite. When a mosquito coil is burned, the coil’s active ingredient will evaporate with the smoke and help to repel or kill mosquitoes.

Are Mosquito Repellent Coils Effective?

When used according to the label, scientific data shows that mosquito coils can repel and get rid of mosquitoes, and can also reduce the ability of mosquitoes to feed on humans or pets. Burning mosquito coils that contain pyrethrum can also significantly reduce mosquito biting rates outdoors. Mosquito coils are most effective in areas such as porches and patios where the wind is usually minimal.

Are Mosquito Coils Safe for Humans and Pets?

Mosquito coils are considered safe for humans and other mammals, although some studies highlight adverse health concerns when coils are used in closed rooms. Other safety studies have shown that a mosquito coil poses the greatest safety risk when it’s burnt inside as it generates smoke that can control mosquitoes effectively, but may also contain pollutants of concern. Mosquito coils are safe when used in strict accordance with the registered product label. However, to maximize mosquito coil safety:

  • Do not use indoors.

  • Use with caution to avoid fire hazards. Do not place in direct contact with flammable objects or surfaces.

  • Keep out of reach from children and pets.

  • Cover exposed food to avoid contamination.
