I dont like this its make lot of smkoe which makes me sufogated due to that I feel problem in proper respiration its smkoke is so hard as it kill the mosquitos but unhealthy for humans also. A mosquito coil is a mosquito repelling incense, usually shaped into a spiral, and typically made from a dried paste, so frnds I dont suggest u to use it its so harmful causing headache n sneazing all that.
