Bird mites in the house are typically caused by migration from nests in which location?

• A. Basements
• B. Eaves or rafters
• C. Attics
• D. Inside closets

Answer: (B)

Bird mites live in bird nests and will move into nearby buildings when birds nest on or near a home. The most common source is nests built in outdoor parts of the house, especially under the eaves or in the rafters along the roofline. From there, mites can slip through small gaps in soffits, vents, or cracks and creep into living spaces, where they may feed on people or pets. While attics can harbor nests and basements or closets might harbor related mites in some cases, the usual entry point and migration path into the home is from nests in the eaves or rafters because those sites are directly adjacent to the interior and provide the easiest route inside.
