Which practice reduces mosquito breeding by removing standing water and other breeding sites?

• A. Sanitation
• B. Cultural
• C. Chemical
• D. Biological

Answer: (A)

Removing standing water and other breeding sites targets the source of mosquito production. This environmental management approach—sanitation—focuses on eliminating the places where mosquitoes lay eggs and their larvae develop. By draining or covering containers, fixing leaky infrastructure, cleaning gutters, and removing discarded items that collect water, you cut off the larval habitat and prevent new mosquitoes from reaching adulthood. Other methods, like chemical or biological controls, reduce mosquitoes after they hatch or are adults, and cultural practices rely on behavior changes to lower breeding opportunities. Sanitation directly reduces breeding by removing the habitats mosquitoes need, making it the best fit for this goal.
