Most mosquito vectors are active during which times of day?

• A. At Sunset and Dawn
• B. Midday hours
• C. Around Noon
• D. At Night

Answer: (A)

Mosquito feeding activity is strongly influenced by light and humidity, and many species hunt most actively during low-light periods. The times around sunset and around sunrise are when conditions are typically ideal—cooler temperatures, higher humidity, and less direct glare—making it easier for mosquitoes to fly and locate a host. This crepuscular pattern is common across many vector species, which is why feeding peaks tend to occur at these times. Keep in mind there are exceptions: some species bite mainly during the day and others mainly at night, but the majority of mosquito vectors show heightened activity at dawn and dusk. This understanding helps explain why protective measures and monitoring are often emphasized for these crepuscular windows.
