Mosquito Repellent Coils

Mosquito Coils are a form of mosquito-repelling incense, usually shaped   into  a  spiral, and typically made from a dried pyrethrum (a flower). The chemical pyrethrin is an insecticide. In  recent  years  another chemical, d-Allethrin is also being used. The coil is usually held  at the centre    of   the    spiral   suspending it in the air to allow continuous smouldering, producing a mosquito repellent  smoke. A typical mosquito coil can measure  up  to  15  cms  in diameter  or more and  can last from 8 hrs to 10 or 12 hrs. The advantages are that the coils need no power supply; therefore highly preferred in rural areas, areas with frequent power     shedding, by pavement dwellers, construction workers. They are cheap and need  no special equipment. They are portable and fit into  normal  household  practices of lighting candles and incense. The disadvantages are that the smoke that  emanates might  cause  allergy by burning  of  these  coils. Keeping the windows partially open however, drives the smoke away. Now-a-days no smoke or less smoke emitting coils are also being   manufactured and marketed.
