Flying squirrels are small, nocturnal creatures that often go unnoticed until they’ve established a presence in a home. While they are generally non-aggressive, their activity can lead to property damage and potential health risks. Identifying an infestation early is essential for effective prevention and removal.
Noises at Night
Flying squirrels are most active after dark. Homeowners often notice:
- Scratching or scampering sounds in the attic, walls, or ceilings
- Squeaking or high-pitched chirps, especially during mating and nesting season
- Sounds of movement that seem to come from areas near insulation or stored items
If these noises appear suddenly in the spring or fall, it could indicate that flying squirrels are actively exploring or nesting in your home.
Evidence of Droppings
Flying squirrel droppings are small, dark, and pellet-shaped. Common locations include:
- Attics, crawl spaces, and wall voids
- Near entry points such as vents or gaps in the roofline
Droppings can carry pathogens and should be handled carefully. Their presence often confirms active occupation, not just exploratory visits.
Signs of Gnawing or Nesting
Flying squirrels have continuously growing teeth, so they frequently gnaw on wood, insulation, and wires. Look for:
- Chewed vents, fascia boards, or soffits
- Shredded insulation or paper materials used for nesting
- Damage near rooflines, attics, and chimneys
Unchecked gnawing can lead to structural damage and fire hazards if wiring is compromised.
Sightings Around Your Property
Flying squirrels are nocturnal and rarely seen during the day, but you may notice:
- Gliding between trees near your home, especially at dusk
- Small, rounded nests in tree cavities or attics
- Scraps of fur, nesting material, or food remnants in and around rooflines
Even occasional sightings warrant inspection, as a single pair can produce multiple offspring each year.
Entry Points
Flying squirrels only need a small opening — often as little as 1.5 inches — to enter your home. Common access points include:
- Gaps in siding or fascia
- Roof vents, chimneys, and soffits
- Overhanging tree branches that provide access to the roof
Identifying and sealing these points is critical for preventing future infestations.
Why Professional Inspection Matters
Flying squirrels can cause damage and present health risks if left unchecked. Attempting to remove them without proper knowledge can be ineffective or even illegal during nesting season. A professional wildlife control technician can:
- Conduct a thorough inspection
- Identify all potential entry points
- Implement humane and effective exclusion methods
- Provide long-term prevention strategies
Take Action Early
Early detection is the key to minimizing damage and avoiding more extensive infestations. If you notice any of the signs above, scheduling a professional inspection can help ensure your home remains secure from flying squirrels and other wildlife.
