Squirrels nest in trees or on the ground, using materials like twigs, leaves, moss, and fur to build their nests.
Squirrels usually reside in the trees and rarely nest on the ground but chipmunks often times burrow and nest in holes in the ground rather than holes in the trees. Chipmunks like to live in the insulation of the walls of your house if there is easy access into a wall near or below ground level as well.
