Flying squirrels may seem harmless—or even fascinating—but when they take up residence inside your home, they can create serious problems. Although these small nocturnal animals rarely interact directly with people, their presence inside attics, walls, and crawl spaces often leads to hidden damage and health risks. At Covenant Wildlife, we regularly help homeowners address flying squirrel infestations before minor issues turn into major concerns.
Because flying squirrels are quiet, agile, and active at night, infestations often go unnoticed for weeks or even months. Therefore, understanding the risks they pose is critical for protecting both your home and your family.
What Are Flying Squirrels?
Despite their name, flying squirrels do not actually fly. Instead, they glide using a membrane that stretches between their front and back legs. However, this ability allows them to travel impressive distances and easily access rooftops, attics, and upper levels of homes.
Flying squirrels are:
- Small and lightweight
- Nocturnal, meaning they are most active at night
- Highly agile climbers
- Capable of squeezing through very small openings
Because they prefer dark, enclosed spaces, attics and wall voids make ideal nesting areas. As a result, many homeowners don’t realize they have a problem until damage has already occurred.
Why Flying Squirrels Enter Homes
Flying squirrels typically enter homes in search of warmth, shelter, and food. Although they primarily live in wooded areas, residential neighborhoods provide easy access to nesting sites and consistent food sources.
Common reasons flying squirrels enter homes include:
- Cold or wet weather
- Easy roof or soffit access
- Nearby trees close to the structure
- Available nesting materials
- Protection from predators
Therefore, once they find a suitable entry point, they may remain for extended periods, especially during colder months.

Common Entry Points Flying Squirrels Use
Because flying squirrels are small and flexible, they can exploit openings that many homeowners overlook. Additionally, their climbing ability allows them to access areas other wildlife cannot.
Typical entry points include:
- Roofline gaps and fascia boards
- Soffit and vent openings
- Chimney gaps and flashing failures
- Attic vents without proper screening
- Small holes near eaves or siding
As a result, even well-maintained homes can become vulnerable without proper inspection and sealing.
Structural Damage Caused by Flying Squirrels
Although flying squirrels are small, their impact on a home’s structure can be significant over time. Because they chew, nest, and move repeatedly through confined spaces, damage often accumulates unnoticed.
Chewed Wiring and Fire Hazards
Flying squirrels constantly chew to keep their teeth from overgrowing. Unfortunately, this often includes electrical wiring. Therefore, exposed or damaged wires significantly increase the risk of electrical fires.
Insulation Damage
Flying squirrels nest in attic insulation, compressing and tearing it apart. Additionally, they contaminate insulation with urine and droppings. As a result, insulation loses its effectiveness, leading to higher energy bills and reduced indoor comfort.
Wood and Structural Wear
While flying squirrels don’t typically chew structural beams aggressively, repeated movement and nesting can weaken wood over time. Furthermore, moisture from waste can contribute to rot or deterioration in enclosed areas.
Health Risks Associated with Flying Squirrels
Structural damage is only part of the concern. Flying squirrels also pose health risks due to the waste and parasites they leave behind. Because these issues are often hidden, they can affect indoor air quality and overall health.
Droppings and Urine Contamination
Flying squirrel droppings accumulate quickly in attics and wall voids. Additionally, urine soaks into insulation and wood, creating strong odors and bacterial growth. As a result, contaminated materials may spread airborne particles throughout the home.
Parasites and Secondary Pests
Flying squirrels can carry:
- Fleas
- Mites
- Ticks
Therefore, even after squirrels leave, parasites may remain and spread into living areas. This creates additional discomfort and potential health risks for both humans and pets.
Air Quality Concerns
As droppings dry and break down, particles can become airborne. Because HVAC systems often pull air from attic spaces, contaminants may circulate through the home. Consequently, residents may experience respiratory irritation or allergy-like symptoms.
Why Flying Squirrel Problems Are Often Missed
Flying squirrels are nocturnal and relatively quiet compared to larger wildlife. Therefore, infestations frequently go undetected until damage becomes extensive.
Signs homeowners may notice include:
- Light scratching or rustling sounds at night
- Faint odors in upper levels of the home
- Unexplained increases in energy bills
- Droppings found near attic access points
Because these signs are subtle, professional inspection is often required for proper identification.
Why DIY Solutions Fall Short
While it may be tempting to attempt a DIY solution, flying squirrel removal is rarely successful without professional expertise. Therefore, improper removal methods often make the problem worse.
Common DIY mistakes include:
- Sealing entry points while squirrels are still inside
- Using ineffective repellents
- Failing to identify all access points
- Ignoring contamination and cleanup
As a result, trapped animals may cause further damage, or new squirrels may simply find another way in.
The Importance of Humane Wildlife Removal
Flying squirrels are protected wildlife in many areas, which means humane removal methods are essential. Additionally, ethical wildlife control ensures long-term solutions rather than temporary fixes.
Professional wildlife removal typically includes:
- Thorough inspection of the structure
- Identification of all entry points
- Humane exclusion techniques
- Proper sealing and repair
- Sanitization and cleanup
Because humane methods prevent re-entry and protect the animals, they are the most effective long-term approach.
Preventing Future Flying Squirrel Infestations
Once flying squirrels are removed, prevention becomes the next priority. Therefore, proactive measures help protect your home moving forward.
Effective prevention strategies include:
- Sealing roofline gaps and vents
- Trimming tree branches away from the home
- Installing wildlife-proof vent covers
- Repairing damaged soffits and fascia
- Scheduling routine inspections
Additionally, ongoing maintenance reduces the likelihood of future infestations from flying squirrels or other wildlife.

Why Professional Inspection Matters
Because flying squirrel damage is often hidden, professional inspections play a critical role. Experienced wildlife specialists know where to look and what signs indicate active or past infestations.
Professional inspections help:
- Identify hidden damage
- Detect health hazards early
- Prevent costly structural repairs
- Ensure complete removal
As a result, homeowners gain peace of mind knowing their home is protected.
