Destroying their breeding places

Depending on the breed of mosquitoes, water sources should be treated, covered up or drained. This is the most effective method.

Chemical control

Pouring oils such as diesel, kerosene or mosquito larval oil on the surface of stagnant water cuts off air supply to pupae and kills them. But this can't be done to large water bodies as it will render water unfit for drinking and kill fish. Paris green (Copper acetoarsenite) and larvicides such as Fenthion are also used.

Spraying

Spraying DDT on surfaces where mosquitoes rest is effective for over six months. This can be tried in residential areas. Pyrethrum flower extract can also be sprayed. It is a nerve poison and kills mosquitoes instantly. But it cannot prevent mosquitoes flying in from other places and breeding.

Protection

Mosquito nets

If you have a little patience and if you do not have the habit of getting up frequently at night, this is the best option. A rectangular net, made of white cotton with fine holes is the best kind. White colour helps easy detection. Cotton fabric is cooling (Unlike nylon nets). But if you forget to tuck in tight, the mites will have a midnight feast.

Screens

Fine meshes such as netlon keep out mosquitoes effectively. But this means closing windows, compromising on natural illumination and ventilation.

Repellents

Mosquito mats, creams and coils have been found to be pretty effective against mosquitoes.
