Which of the following strategies helps reduce mosquito breeding near buildings?

• A. Keep standing water and decorative water features.
• B. Increase outdoor lighting and leave drains open.
• C. Eliminate standing water, screen openings with fine mesh, maintain proper drainage, and avoid decorative water features that stagnate.
• D. Use open water features to attract predators.

Answer: (C)

Preventing mosquito breeding near buildings comes down to removing standing water and limiting opportunities for larvae to develop. Mosquitoes lay eggs in still water, and even small accumulations can become thriving habitats, so eliminating that water, ensuring proper drainage away from foundations, and keeping gutters and containers from pooling water reduces the places where larvae can grow. Screening openings with a fine mesh helps keep adult mosquitoes from entering living spaces and from using small adjacent water sources to feed, while avoiding decorative water features that stagnate removes potential larval habitats altogether. When these steps are followed, the overall environment around the building becomes much less hospitable to mosquitoes.

Keeping standing water around or leaving drains open creates and preserves breeding sites, so those choices tend to increase mosquito presence. Adding outdoor lighting or relying on open drainage does not address the core breeding issue and can even attract more mosquitoes. Creating open water features to attract predators is not a reliable or direct method for reducing breeding near buildings and can still allow larvae to develop if the water stagnates.
