The fragrant fume from the burning incense stick kills the mosquitoes effectively and keeps the ambiance free from mosquitoes for about an hour after the stick extinguishes. The fume also disturbs ants and makes them ineffective. Each incense stick lasts for about an hour. Mosquito sticks contain insecticides, which are expected to vaporize slowly once the coil is lit, to provide protection against the mosquito.

Mosquito sticks 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. It is effective against malaria, dengue, and chikungunya-carrying mosquitoes.
