Which of the following best describes a comprehensive approach to reducing mosquito habitat?

• A. Regularly empty water from containers, remove debris blocking drains and gutters, adding mesh screens to rainwater barrels, or adding fountains or bubblers to keep water moving in ponds or bird baths.
• B. Use broad-spectrum foggers daily.
• C. Let standing water remain in containers.
• D. Apply insecticide to soil.

Answer: (C)

Reducing mosquito habitat works best when you remove the places where mosquitoes can lay eggs and larvae. Since mosquitoes breed in still water, the most effective approach is to minimize and manage any standing water across the environment. Regularly emptying water from containers prevents larvae from having a place to develop. Clearing debris that blocks drains and gutters helps keep rainwater from pooling. Adding mesh screens to rainwater barrels stops mosquitoes from accessing water inside to lay eggs. Keeping ponds, bird baths, and other water features with moving water—using fountains or bubblers—prevents the surface from staying still long enough for mosquitoes to breed. Other options miss the mark because they don’t address the breeding sites: using foggers broadly doesn’t reduce habitat and can cause other problems; leaving standing water in containers creates more breeding sites; and applying insecticide to soil won’t affect mosquito larvae living in water. The comprehensive approach is to eliminate standing water and keep water from stagnating, which directly reduces mosquito habitat.
