Flying Squirrel Biology:Flying squirrels are extremely small in size compared to other squirrel members, such as the gray and fox squirrels. They have a broad flattened tail, enlarged eyes, and a patagium. The patagium is extended folds of skin from the wrist to ankle that enables it to fly. The flying squirrel has two litters per year, one in early spring, the other in mid-summer. Each litter producing from one to six young. Flying squirrels usually live in medium (3-9) or large (8-15) communal families.
Flying squirrels are nocturnal and feed mostly on insects, nuts, fruits, seeds and berries. They do not hibernate, but may stay in the nest during bad weather.
Nuisance Concerns: Flying squirrels may cause damage when they enter buildings via construction gaps, dormer and louver vents, chimneys, fascia boards and soffits. Their entrance hole is often times the size of a quarter. Squirrels have been responsible for starting fires by chewing on electrical wires. Other damages include accumulated droppings, urine stains, chewing and gnawing on wood, and degradation of insulation. On rare occasions, carriers of rabies and typhus. There are various approaches for controlling flying squirrels. Prevention of the flying squirrel entry, or excluding the site, is of extreme importance in solving this situation. Another technique is humanely live-trapping the flying squirrels from the space. Cage trapping flying squirrels can be utilized, using nuts and vegetables. We also recommended installing chimney caps on any uncovered chimney, to prevent unwanted flying squirrel entry.
