Which action is part of basic household source reduction to reduce Aedes breeding?

• A. Use insecticide sprays indoors weekly
• B. Eliminate standing water in containers
• C. Install mosquito repellent devices
• D. Release fish into streams

Answer: (B)

Eliminating standing water in containers is the key idea here because Aedes mosquitoes breed in small amounts of still water found around the home. Their eggs hatch and larvae develop directly in these tiny, often everyday containers—flower pot trays, buckets, pet dishes, gutters, discarded tires, and similar places. By regularly emptying, cleaning, covering, or turning over these containers, you remove the aquatic habitat they need, interrupting the life cycle before adults can emerge.

Other options don’t target this breeding habitat: indoor insecticide sprays and personal protective devices address mosquitoes after they emerge as adults rather than removing their larval sites, and releasing fish into streams doesn’t address the common household containers where Aedes commonly breed.
