Flying Squirrels
Flying squirrels can control their glide and speed, by direction, angle and destination, and have been recorded to glide as far as the length of a football field.


Two species of flying squirrels are found in Greater Boston: the northern and southern flying squirrel. These rodents are not capable of true flight like birds or bats. Though they are actually quite common throughout the United States, flying squirrels are rarely encountered by humans because they are nocturnal.


  • Gray or brown fur
  • Bellies of northern flying squirrels typically appear gray
  • Bellies of southern flying squirrel are white
  • These rodents can grow between 8 and 14 inches (20 to 35 cm) long, with their tails accounting for at least half of their length, and northern flying squirrels are about two inches longer than their southern cousins on average.
  • Flat tails that function as brakes during flight
  • Flaps of skin that extend from their ankles to their wrists that function similarly to parachutes
  • Large dark eyes that help them see in the dark


Southern flying squirrels prefer to nest in deciduous forests of seed-producing hardwood trees where they feed on fruit and nuts from trees such as red and white oakhickory and beech. Northern flying squirrels live in coniferous and mixed forests, and feed on fungi of various species, though they also eat lichensmushrooms, all mast-crop nuts, tree sap, insects, carrion, bird eggs and nestlings, buds and flowers. Both species build nests out of twigs, bark, feathers, fur, and leaves in abandoned bird nests, dying trees, and woodpecker holes.

Flying Squirrel Problems


Flying squirrels often construct nests in ornamental and shade trees on lawns, in barns and sheds, and in attics. They may also take up residence in parks, golf courses, and other areas with constant human activity and sufficient vegetation, though they are seldom seen by people due to their nocturnal habits.


As they are responsible for the spread of fungi spores and seeds of trees, flying squirrels are largely considered beneficial. However, they become problematic when they move onto lawns and into attics - as they make a lot of sound at night. Additionally, their urine smells foul and can carry harmful bacteria. Flying squirrels also gnaw on walls, structural support beams, and electrical wires.

Squirrel Control

Control and Safety

Property owners can make modifications to homes and yards to ensure the surrounding area is less favorable to flying squirrels. Close up any and all possible entry points to homes by covering small openings, sealing cracks, replacing broken window and door screens, and adding screens to vents and chimneys. Remove possible sources of food by fitting indoor and outdoor trash bins with tightly sealed lids. Finally, restrict flying squirrel access to roofs by trimming tree branches that hang over or close to rooftops.

Trapping and Removal

Though humans and flying squirrels are typically able to coexist peacefully, females become aggressive when they feel their territory is threatened. Untrained individuals should never attempt to approach the wild animals as interaction may result in injury or disease. Contact the technicians at Critter Control for humane and safe removal of flying squirrels from private property.
