Fox Squirrel

The fox squirrel (Sciurus niger), found throughout the state, is the largest of the four tree squirrel species in Indiana.

The other tree squirrels are:

General characteristics


  • Total body length of 17 to 28 inches.
  • Tail length 8 to 13 inches.
  • Weight ranges from 1 to 2.2 lbs.
  • Coloration: Upper body is a grizzled black-brown-orange combination with brown under parts; occasionally will be colored black above, white below; may have white ears and nose, or have a white tail.
  • Sharp claws for climbing.
  • Fox squirrels can live six years in the wild and longer in captivity.


  • Agile climbers that spend more time on the ground than other tree squirrel species.
  • They rise and feed later than other squirrels and are more active throughout the day.
  • Large vocabulary of barks and clucking sounds.
  • Capable of jumping up to 15 feet in horizontal leaps and free-falling 20 feet or more to land on a limb or tree trunk.


Tree holes and cavities are remodeled for winter dens and often serve as nurseries for late winter litters. If existing trees lack cavities, leaf nests, known as dreys, are built by cutting twigs with leaves attached and weaving them into warm waterproof shelters. Dreys enable fox squirrels to live in less mature trees. Similar leafy platforms are built for summer loafing.

Fox squirrels breed twice a year if conditions are right, in December/January and again in early summer.

Fox squirrels  average  three 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 12 weeks, young are weaned and begin to fend for themselves. Squirrels produce fewer offspring than other mammals but are more successful in rearing them.

Food habits

Fox squirrels eat much the same foods as other tree squirrels:

  • White oak acorns
  • Hickory nuts and beechnuts
  • A wide variety of seeds
  • Berries and wild fruits.

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.

Squirrels don’t hibernate, so they must depend upon buried acorns and nuts, or bird feeders for winter fare. Many acorns buried in the fall are never found and later sprout to become trees. In addition to burying nuts, squirrel carry seeds and berries to new areas and are known as important dispersers of plants seeds.


In pre-settlement times, fox squirrels only occupied the savannah habitat found along the fringes of the prairie in what would later be northwest Indiana. As settlements developed and deforestation occurred, the fox squirrel expanded its range. It has been less than a century since this species moved into central and southern counties. This timber removal, which nearly spelled the end for gray squirrels, allowed fox squirrels to move into every corner of the state. Somewhere between solid virgin forests and total timber destruction, a favorable balance of cover enables fox squirrels to achieve optimal population levels. Recently, losses of large mature trees and fencerow or hedgerow habitat for increased crop production or urban development have caused fox squirrel numbers to diminish in some parts of the state.


Fox squirrels and gray squirrels can be harvested legally during the squirrel hunting season. They may be taken with any equipment and ammunition during squirrel hunting season, though a .22-caliber rifle or 410-gauge shotgun is recommended. Hunters must meet fluorescent orange clothing requirements while hunting squirrels from the first Friday in November after Nov. 3 through the end of the season. Hoosier hunters harvest approximately 300,000 fox squirrels annually. Buy an Indiana Hunting License.

It is legal to hunt squirrels from a boat that is not under power from a motor. Fluorescent orange clothing is not required while hunting squirrels from a boat. Shooting into or disturbing leaf nests or squirrel dens is illegal at all times.

Living with squirrels

Fox squirrels are notorious for raiding birdfeeders and gorging themselves. “Squirrel-proof” feeders are available, and some are affective.

Because birdfeeders have provided a food source in areas that may lack adequate den or nest trees, squirrels are increasingly invading homes, particularly attics.

Resident landowners and tenants can live-trap a fox squirrel that is causing damage on their own property without a permit from the DNR. The fox squirrel must be euthanized or released within the county of capture on property in which you have permission. In order to prevent the spread of disease, the DNR encourages homeowners to safely and humanely euthanize the fox squirrels, if possible. Live-traps can be purchased from hardware stores and garden centers. If you do not want to trap the squirrel yourself, contact a licensed nuisance wild animal control operator.

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. 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 addition to these commercial products, homeowners could try natural repellents like chili or cayenne pepper in the attic or outside the home, or even use a strobe light in the attic. The most effective way to remove squirrels from buildings is to find out how they are getting in and out, and trap them at the source. It is best to set traps, live or kill, to catch them as they exit the building. Again, homeowners may want to contact a licensed nuisance wild animal control operator to conduct or assist in this effort. Once all the squirrels have been removed, permanently seal the entry point; tightly woven wire mesh (not chicken wire) will do the trick if covering a vent or chimney. Trim overhanging tree limbs to prevent easy access to your roof and attic.

Fox squirrels have been known to strip the bark from the upper branches of trees. This behavior typically occurs in early spring and early fall in response to their increased need for sodium. Sap, flowing up from the roots into the branches of trees in the spring and energy rich sap being produced in the fall, contain higher concentrations of sodium. Squirrels will peel back the thinner, more pliable bark, on the younger tree branches to get at the sodium-rich sap. Certain glues used in making plywood, as well as chemicals found in electric wire insulation, may also contain sodium and lead to squirrels chewing on these objects. Since the damage is directly related to squirrels needing more sodium (salt), the problem can often be mitigated by making alternative sources of salt more readily available. Small mineral/salt blocks or rings can be purchased from local pet supply stores and placed at the base of the trees being damaged or in the crooks of easily-accessible branches. Soak wooden stakes in salt water for 24 hours and then either place the stakes in the ground around the affected trees or wire them to the tree trunks.

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.
