Flying squirrels might be one of nature’s cutest woodland creatures, but when they decide to take up residence in your attic, shed, garage, or walls, they can quickly turn from charming to costly. These small, nocturnal rodents are highly social, resourceful, and surprisingly destructive — causing damage to your home and property while remaining mostly out of sight.
In this post, we’ll cover how flying squirrels enter your home, the damage they can cause, why their presence poses a risk, and how you can prevent problems with a helpful homeowner’s checklist. And when you need expert help, Advanced Wildlife Control is the trusted team to call.
About Flying Squirrels
There are two species of flying squirrels found in North America: the Northern Flying Squirrel and the Southern Flying Squirrel. Both are small, with soft grayish-brown fur, large eyes adapted for night vision, and a special membrane called a patagium that stretches from wrist to ankle, allowing them to glide distances of up to 150 feet.
Flying squirrels are nocturnal, preferring to forage and move about at night. They are rarely seen by homeowners, which makes their infestations particularly sneaky and problematic. These squirrels are also social animals, often living in family groups of 6–12 or more, especially in colder months when they cluster together for warmth.
How Do Flying Squirrels Get Inside?
Despite their small size — typically only 8 to 12 inches long including the tail — flying squirrels can cause outsized problems in homes and outbuildings. They’re agile climbers and excellent problem-solvers, able to squeeze through openings as small as 1 inch in diameter.
Common entry points include:
- Gaps along the roofline and ridge vents
- Soffit and fascia openings
- Uncovered chimneys
- Gable, attic, or dryer vents
- Loose or damaged siding
- Openings around pipes, wires, and cables
They typically nest in attics, walls, sheds, garages, or under eaves, where they feel protected and hidden from predators.
Why Is This a Problem?
Once flying squirrels move into a structure, several issues can quickly follow:
Chewing Electrical Wiring
Like all rodents, flying squirrels need to gnaw constantly to keep their teeth from overgrowing. Chewing on electrical wires can cause dangerous short circuits and increase fire risk.
Insulation Destruction
They rip apart insulation to build nests, leading to reduced energy efficiency and higher utility costs.
Structural Damage
Gnawing on wooden beams, rafters, and soffits weakens structural integrity and compromises your home’s weatherproofing.
Accumulation of Droppings and Urine
Flying squirrels create latrine areas, and over time, urine and droppings can saturate insulation and ceilings, causing stains, unpleasant odors, and increasing the risk of mold and airborne bacteria.
Health Risks
Their droppings and nesting materials can harbor parasites, fleas, ticks, mites, and harmful bacteria like salmonella. The risk of airborne pathogens like leptospirosis increases in closed, poorly ventilated areas like attics.
Noise Disturbances
As nocturnal animals, their activity can disturb sleep with nighttime scratching, squeaking, or scurrying in walls and ceilings.
Attracting Other Pests
Holes and openings created by squirrels can invite bats, mice, and insects, compounding the problem.
Signs You May Have Flying Squirrels
Since these animals are most active at night, it’s important to recognize subtle signs:
- Scratching, squeaking, or scurrying sounds from ceilings, attics, or walls — usually at dusk or before dawn
- Droppings resembling small, elongated pellets (similar to mouse droppings but slightly larger)
- Debris on the roof like insulation
- Staining that looks like molasses
- Strong, musty odors in attics or enclosed spaces
- Visible damage near vents, eaves, soffits, or roofline
- Nests made of insulation, leaves, or fabric
- Glimpses of small, grayish animals gliding between trees or from your roofline at dusk
Homeowner’s Flying Squirrel Prevention Checklist
Take these steps to help secure your home and property year-round:
- Install chimney caps and screen attic, gable, and dryer vents
- Seal any openings larger than ¼ inch around rooflines, soffits, and fascia boards
- Check and secure loose or damaged siding and trim
- Seal gaps around pipes, electrical lines, and cable entry points
- Prune overhanging tree limbs at least 6–8 feet from the roof
- Keep firewood piles and debris away from your home’s foundation
- Inspect sheds, garages, and outbuildings for gaps and secure them
- Install motion-activated outdoor lights near rooflines and entry points
- Schedule annual attic, roofline, and exterior inspections
- Pay attention to unusual sounds in walls, attics, or ceilings — especially at night
Why Professional Removal Matters
It’s essential to address a flying squirrel problem promptly — and professionally. Attempting DIY removal can be risky, as these animals are quick, elusive, and protected in some regions under local wildlife laws. Trapping and exclusion should be handled humanely and in compliance with regulations.
That’s where Advanced Wildlife Control comes in. With years of experience safely handling flying squirrel problems, their trained specialists provide professional squirrel removal services and long-term wildlife prevention solutions.
Their team will:
- Conduct a thorough inspection of your home, attic, and outbuildings

- Sanitize and deodorize affected areas
- Repair and seal all entry points to prevent future intrusions
Their team is equipped to manage infestations of any size and ensure your home is protected season after season.
