The reason is that squirrels are classic hoarders, spending most of their time storing food. They like to live near trees that bear nuts such as acorns and walnuts, which are suitable for storing over winter. Many squirrels will bury the nuts and then use their good memory and sense of smell to find the stash in winter, when snow covers the ground. In fall, squirrels eat so many nuts that they grow a thick layer of fat in their bodies. They also grow thick, warm fur on their ears and the soles of their feet.
Squirrels can thrive in both forests and cities.
They have been known to nest in chimneys, roofs, garages and attics, using whatever materials are available, including cardboard, newspaper, cloth and attic insulation. Dreys are nests made of interwoven twigs and leaves and lined with moss, feathers, fur or other soft materials. Dens are holes in tree trunks, which are also lined with soft material. Squirrels often use dens in winter and dreys in summer. Ladybugs Don t be surprised if you find a lot of ladybugs in your house during the fall.
