To get rid of mosquito we use many mosquito repellents . One of the method is using coil
which is made up of dried paste of pyrethrum powder. The smoke that is left out after burning is harmful for health, the continuous inhalation of this gas cause irritation in throat.
It has a strong smell and a typical odor which sometimes can cause you a head-ace. they can be fire hazards if the coils are left unattended. the effect of this coil lasts only till the coil is active.
use liquids rather than coils they give you a good effect without a irritating smell and lasts longer than the coils without any adverse effects.
thou this coil is not environment friendly even if its easy to use
