Side effects of mosquito coil

Mosquito Coil Side Effects

Is mosquito coil harmful to health? To find the answer to this question, you should be aware of the side effects associated with mosquito coils. Below are some of the side effects:


The smoke from burning mosquito coils contains various chemicals, including particulate matter, benzene, and formaldehyde. These can irritate the lungs and airways, causing coughing, sneezing, and difficulty breathing.

Asthma and allergies

If you have asthma or allergies, the smoke from mosquito coils can trigger symptoms like wheezing, chest tightness, and runny nose.

Increased risk of lung infections

Prolonged exposure to smoke from mosquito coils may increase the risk of lung infections, particularly in children and older adults.

Children and pregnant women

These groups are more susceptible to the harmful effects of smoke due to their developing lungs and bodies. It's best to avoid using mosquito coils around them.


Using coils in poorly ventilated areas significantly increases the risk of inhaling harmful smoke. Always use them outdoors or in large, well-ventilated areas.

What kind of mosquito coils are harmful to health?

Mosquito coils, while effective at repelling mosquitoes, can be potentially harmful to health due to the chemicals used in their composition. Mosquito coils that may pose health risks include certain synthetic chemicals. Here are some key ingredients found in mosquito coils that can be harmful:


Many traditional mosquito coils use pyrethroids as their active ingredient. Pyrethroids are synthetic insecticides designed to mimic the natural insect-repellent properties of pyrethrins, which are derived from chrysanthemum flowers. Although pyrethroids are generally considered safe when used as directed, prolonged exposure may cause skin irritation and respiratory or allergic reactions in some individuals.


Benzene is a chemical compound found in some mosquito coils, and prolonged exposure to benzene has been linked to various health problems, including an increased risk of cancer.


Formaldehyde in certain mosquito coils is another potential concern. This chemical can irritate the eyes, nose, and throat and have long-term health effects, including respiratory problems and cancer risk.

Piperonyl Butoxide (PBO)

PBO is often used in combination with pyrethroids to improve their insecticidal effect. Although PBO by itself has low toxicity, its use with other chemicals can contribute to the overall health risks associated with mosquito coils.
