The use of mosquito coils has gained widespread patronage in malaria-endemic countries, even though it is not a recommended preventive measure for avoiding mosquitoes. Mosquito coils contain insecticides, which are expected to vaporize slowly once the coil is lit, to provide protection against the mosquito.

Mosquito coils are considered to be safe insecticides for humans and mammals, although some studies highlight concerns when they are used in closed rooms. Mortein coil releases a power booster at each corner that gives protection throughout the night for 12 hours. It is effective against malaria, dengue, and chikungunya-carrying mosquitoes.
