Some of the strategies below are appropriate for individuals, while others are very useful on an area-wide or country wide basis. Screening of Dwellings to Prevent Malaria Mosquitoes from Entering and Biting the People Inside is a positive development measure. Screening of buildings also improves people's lives in other ways, i.e. by keeping flies out of homes. Screening is a useful adjunct to use of a treated bednet or residual treatment of walls because it reduces the number of malaria mosquitoes entering and leaving the building.
Mosquito fish are often particularly effective in small ponds, water tanks etc.
There are several species of malaria vectors, and these species breed in many different locations. If the vector mosquitoes are breeding in water tanks, for example, it is possible to screen the tanks. However, if the malaria mosquitoes are breeding in a swamp, it is not always possible nore wise to attempt to drain the swamp. Thus, other strategies for breaking transmission may need to be used. If they are treated with appropriate drugs, the parasites disappear from their blood and are not available to the mosquitoes.
