What form of mosquito control is most commonly used?

• A. Chemical
• B. Biological
• C. Mechanical traps
• D. Genetic modification

Answer: (A)

Chemical control is the most commonly used form of mosquito control because it can quickly reduce large mosquito populations across wide areas and fits well with established public health operations. This approach includes practices like insecticide spraying to kill adults and larvicides applied to breeding sites, which allow programs to cover extensive areas and achieve rapid population declines. Other methods, such as biological controls, mechanical traps, or genetic modification, are used in more specific contexts or are still being developed and tested, but they don’t match the broad, standardized deployment and immediate impact that chemical control offers.
