Hey friends I am telling you about the very harmful coil i.e mortein. It contains harmful chemical which produces more smoke it is only infecting the humans and it is less effective. Not many people know about it, but the damage done to your lungs by one mosquito coil is equivalent to the damage done by 100 cigarettes. A normal person can have fever or headache due to its smoke. Electric mosquito machine should be used instead of the coil. So I recommend for stoppage of these coils.
