What is the cornerstone of effective mosquito control?

• A. Public education
• B. Surveillance of mosquito larvae and adults
• C. Eliminating standing water only
• D. Using insecticides exclusively

Answer: (B)

The most important factor in effective mosquito control is having solid information about the mosquito populations you’re dealing with. Surveillance of both larvae and adults gives you data on where mosquitoes are breeding, how many there are, what species are present, and when they peak. This information guides every other action—where to target control, whether to use larvicides or adulticides, and when to apply interventions for the best impact. It also helps you detect invasive species, monitor resistance patterns, and measure whether your control efforts are reducing risk over time.

Public education, eliminating standing water, and using pesticides all matter, but they can’t stand alone without data to steer them. Public education helps behavior change but won’t reduce numbers unless you know where and when to act; eliminating standing water helps but isn’t feasible for all breeding sites or timing; relying solely on insecticides can lead to resistance and environmental concerns without surveillance to inform proper use.
