The main component of mosquito coils is pyrofreud. It is found in natural compound pyrograms. Also found in homologous compounds such as alatrin. Matte also has a similar pyrufroid , but requires constant application of a certain temperature. When heated, the pyrofreud of the mat evaporates. The mat has to be placed in the heatpaste of the matheater to apply a certain temperature. Its main active ingredients are chlorinated hydrocarbons like the pesticide DDT or pinden , arpano phosphorus compounds like paraffin and carbon. Allergens are found in almost all mosquito coils.
