Indoor rat nests are commonly located in which set of areas?

• A. In walls, between floors and ceilings, under equipment, between and under pallets, and in crawl spaces
• B. In attics only
• C. In kitchen cupboards only
• D. In water pipes

Answer: (A)

Rats choose protected, dry, and quiet spaces inside a structure that stay close to food sources. The usual indoor nesting spots—inside walls, between floors and ceilings, under equipment, between and under pallets, and in crawl spaces—provide continuous shelter, stable temperatures, and minimal disturbance. These voids also offer ready access to pathways through the building, making it easy to move around while remaining hidden.

Attics can be used, but interior voids are more consistently used for indoor nests because they offer more reliable shelter near daily food sources. Kitchen cupboards are exposed and frequently disturbed, so they’re less suitable as nest sites. Water pipes aren’t ideal either since they’re often damp and cramped, offering poor conditions for a nesting pair or litter.
