Rat and Mouse Nests

Norway rats, roof rats, and house mice all live in groups with a dominant male, a few females, and their offspring. These families may build nests for food storage, sleeping, and raising young.

A rodent nest resembles a loosely woven ball and typically measures four to six inches in diameter.

Norway Rat Nests

Outdoors, Norway rats may dig burrows or build nests beneath rock piles, foundations, and concrete slabs. Inside homes, these rodents nest on lower floors of the house, particularly in basements or crawl spaces.

Roof Rat Nests

These rodents prefer higher ground and often build their nests in trees. In urban settings, roof rats travel along power lines, which lead them onto roofs and into attics. Once inside a home, ripped insulation torn from attic walls often lines a roof rat nest.

House Mouse Nests

In the wild, house mice will nest just about anywhere, including among weeds and rocks or in burrows. Indoors, house mice build nests in hidden areas near food sources and will shred fabric, paper, and other soft materials to use as padding.

Rodent Nest Dangers

Nests tend to be filthy places covered in waste and hair. They can also be a good spot for fleas and ticks to live. Because of the diseases associated with rodent droppings and parasites, homeowners should not remove rodent nests on their own.

Homes with rodent nests likely have a full infestation already underway. For the most efficient means of mice or rat removal, contact the wildlife professionals at Critter Control.
