What will the draining of a pond in mosquito infested area prevent?

Draining a pond in a mosquito infested area can help prevent the spread of mosquito-borne diseases, such as malaria, dengue fever, and West Nile virus. Mosquitoes lay their eggs in standing water, so draining ponds and other bodies of standing water can help reduce the number of mosquitoes in the area. This can make it less likely that people will be bitten by mosquitoes and contract a disease.
