The use of mosquito coil

A mosquito coil offers protection against mosquitos, flies, and other insects, and thus against the diseases they may carry. Examples include malaria, dengue fever, yellow fever, and various forms of encephalitis, including the West Nile virus. To be effective the mesh of a mosquito coil must be fine enough to exclude such insects without reducing visibility or air flow to unacceptable levels. Longer’s Mosquito Coil Product Line can produce the high quality mosquito coil. It is possible to increase the effectiveness of a mosquito coil greatly by treating it with an appropriate insecticide or mosquito repellant.

Mosquito coils are often used where malaria or other insect-borne diseases are common, especially as a tent-like covering over a bed. For effectiveness, it is important that the coilting does not have holes or gaps large enough to allow insects to enter. It is also important to 'seal' the coil properly because mosquitos are able to 'squeeze' through improperly secured coils. Because an insect can bite a person through the coil, the coil must not rest directly on the skin.
Mosquito coilting can be hung over beds from the ceiling or a frame, built into tents, or installed in windows and doors. When hung over beds, rectangular coils provide more room for sleeping without the danger of coilting contacting skin, at which point mosquitos may bite through untreated coilting.

Where mosquito coils are freely or cheaply distributed, local residents sometimes opportunistically use them inappropriately, for example as fishing coils. When used for fishing, mosquito coils have harmful ecological consequences because the fine mesh of a mosquito coil retains almost all fishes, including bycatch such as immature or small fish and fish species that are not suitable for consumption.In addition, insecticides with which the mesh has been treated, such as permethrin, may be harmful to the fish and other aquatic fauna.
