Squirrels in the attic? Squirrels in your crawl space or eaves? Those scurrying sounds in the attic may well be Gray, Fox, Flying or Pine squirrels - which love to invade attics, and occasionally walls of structures. Call today for removal solutions to rid your home of squirrel problems!


In the US, there are at least 12 species of tree squirrels, 23 species of ground squirrels, and 2 species of flying squirrels! These squirrels can be found in many regions of the country and are classified as game animals in some states. Squirrels however, are unprotected and considered little more than nuisances.


Tree Squirrels:

  • 1 to 2 ft. long, including their bushy tails
  • Grizzled coats are usually shades of gray, brown, or black, and they have lightly colored underbellies

Ground Squirrels:

  • Shorter tails and fur
  • Generally smaller
  • Range in appearance from reddish-gray to smoky brown and may have black spots or stripes

Flying Squirrels

  • Flying squirrels are the smallest of all three types
  • Have webs of skin between their fore and hind limbs used for gliding
  • Typically light brown or gray, flying squirrels are primarily nocturnal and have large eyes to help them see at night.


All types of tree squirrels prefer to live among hardwood or coniferous forests where ground cover is plentiful! Their nests are mostly made of twigs and leaves. Ground squirrels love open grasslands where they dig deep, long burrows with many exits. Flying squirrels make their homes in the crevices of trees or abandoned bird's nests. These small, nocturnal creatures prefer to live in wooded areas where they can glide from treetop to treetop without having to descend to the ground.



Squirrels are commonly seen when walking outside. As opportunistic omnivores, they feed off human food and garbage as much as possible! Although they do love their acorns. Tree squirrels and flying squirrels have been known to enter unsecured attic spaces to nest, and ground squirrels often burrow in yards or farmers' fields in search of food or shelter.


Taking advantage of any available food source, squirrels damage yards and fields by digging for nuts and insects. When ground squirrels burrow near manmade embankments or dams, they weaken the structural integrity, and may then cause collapses! Flying squirrels and tree squirrels damage homes by gnawing or tearing at insulation and electrical wires on roofs and in attics. These rodents can also cause power outages when they run across power lines!


Control and Safety

Protecting your personal property from squirrels can be challenging since the rodents can simply burrow underneath or climb over most fences! However, electrified fencing can be effective. Tree squirrels and flying squirrels can be kept from entering attics by sealing all possible external entrances and pruning tree limbs that hang over roofs.
