Fox Squirrels

The fox squirrel is the largest of the 4 most common tree squirrels. The other tree squirrels are the gray squirrel, red squirrel, and southern flying squirrel.

Although fox squirrels are often seen on the ground, they climb well and are seldom found far from trees. They rise and feed later than other squirrels and are more active throughout the day. Their conspicuous barking and squalls often betray their presence.

Fox squirrels breed in December and January and again in early summer, if well nourished, and produce about 3 pups per litter. Young are born in every month but December and January, and squirrels born in early litters may breed and produce young of their own in their first year of life. In eight to twelve weeks, young are weaned and begin to fend for themselves. Squirrels produce fewer offspring than other mammals but are more successful in rearing them. Fox squirrels may live six years in the wild and longer in captivity.

Fox squirrels eat much the same foods as other tree squirrels. White oak acorns, hickory nuts and beechnuts are preferred, but a wide variety of seeds, berries and wild fruits are consumed when choice items fall. When frost, insects, droughts and other unfavorable conditions cause wild foods to fail, squirrel population can decline. However, fox squirrels have adapted to human provided food sources. Since they typically live closer to cropland than other squirrel species, corn can become a main part of their diet. Additionally, many have taken advantage of the boom in popularity of bird feeding.

To the dismay of many homeowners and birdwatchers, fox squirrels are notorious for raiding bird feeders and gorging themselves. “Squirrel-proof” feeders are available, and some are quite effective. Because bird feeders have provided a food source in areas that may lack adequate den or nest trees, squirrels are increasingly invading homes, particularly attics. Squirrels will need to be removed from buildings before entry points can be sealed. Numerous products are specifically labeled for use as squirrel repellents. Do not use products with noxious chemicals if they are not labeled for use on squirrels, such as mothballs. However, no commercial product is completely effective in repelling squirrels from buildings.

In urban areas, fox squirrels become used to people and would appear to make good pets, but fox squirrels are wild animals that will bite and can carry disease. Do not try to pick up squirrels. Occasionally, squirrels may enter a house through a pet door. Quietly open windows and a door through which the animal may exit and close the doors that provide access to other parts of the house before leaving the room. Wait quietly for the animal to escape. If a squirrel is already in your chimney or attic, they will need to be removed from the building before entry points can be sealed. Trim overhanging tree limbs to prevent easy access to your roof and attic.
