Correct answer: B — Drum emptying, daytime personal protection and focal adult control

The best answer is “Drum emptying, daytime personal protection and focal adult control”. Aedes vectors are predominantly day-biting and exploit small peri-domestic containers. Source reduction or secure covering of productive drums, personal daytime protection and proportionate targeted adult control during an outbreak address both immature and adult stages. Bed nets alone miss the main biting period.
