What is the purpose of harborage areas in mosquito control?

• A. They provide concentrated daytime resting areas where adult mosquito control can be applied.
• B. They are used to trap mosquitoes.
• C. They attract natural predators to reduce populations.
• D. They are breeding sites for larvae.

Answer: (C)

Harborage areas are used to invite natural predators to the scene by providing shelter where they can rest and hunt. By giving predators—such as dragonflies, birds, bats, and other beneficial insects safe places to perch and take up residence, you bolster their ability to prey on mosquitoes. This supports a natural, long-term reduction in mosquito numbers without relying solely on chemicals. It’s different from creating sites to trap mosquitoes or providing breeding habitats for larvae; those approaches don’t leverage natural enemies in the same way. Harborage areas can include dense vegetation, brush piles, or bat houses—things that make the area more attractive and safer for predators to operate.
