Why Are Flying Squirrels In My Home

Flying squirrels may enter your home in search of warm and safe shelter during the winter months. They can access your home through chimneys, roofline holes, unsecured vents, or holes in siding. Once inside, they are commonly found in attics, wall voids, under floors, and insulation. It is important to address any entry points and remove the squirrels from your home to prevent damage and potential health risks.

Damage Flying Squirrels Create

It’s important to be aware of the damage that flying squirrels can cause. Here are some signs that indicate their presence and the harm they can create.

1. Torn Attic Insulation and Nests

Flying squirrels often tear up attic insulation and use it to build their nests. If you notice torn insulation or find nests made of stored clothing, it’s a clear sign that flying squirrels have been active in your home. This can lead to reduced insulation effectiveness and the need for costly repairs.

2. Chewed Wires

Flying squirrels have a tendency to chew on wires, which can cause power shortages or even start a fire. If you discover wires that have been chewed on, it’s crucial to address the issue promptly to prevent any electrical hazards.

3. Ammonia Smell

One unpleasant aftermath of flying squirrels is the strong smell of ammonia. This scent is left behind from their urine and can be quite unbearable. If you detect a strong ammonia odor in your home, it’s a sign that flying squirrels have been present and left their mark.

4. Droppings

Finding droppings scattered around your house is a definite indicator of flying squirrel activity. These droppings are not only unsightly but also pose a health risk as they can carry diseases. Proper cleaning and prevention measures should be taken to ensure a safe and sanitary environment.

If you observe any of these signs of damage caused by flying squirrels, it’s important to take immediate action to address the issue. Seeking professional assistance can help effectively remove the squirrels from your home and prevent further damage.

Signs of a Flying Squirrel Infestation

Spotting signs of a flying squirrel infestation is important in order to address the issue promptly. Some common signs include chew marks on wood or the roofline, as well as small entry points. Additionally, you may hear constant chatter and playful sounds from the squirrels, especially in the evening.

Flying squirrels are social creatures and often live in colonies of around 20 individuals. If you notice any of these signs, it is recommended to seek professional assistance to handle the infestation effectively.

How to Prevent Flying Squirrel

Preventing flying squirrels from entering your home is crucial to avoid damage and potential infestations. Here are some effective prevention tips:

1. Inspect and Seal Entry Points

Thoroughly inspect the exterior walls, siding, and foundation of your home. Look for any cracks, crevices, or spaces that could serve as entry points for flying squirrels. Seal or repair these openings to prevent their access.

2. Caulk Gaps

Check for any gaps around windows and doors. Use caulk to seal these gaps and prevent flying squirrels from entering your home through these small openings. Additionally, install door sweeps on all exterior doors to block any potential entry points.

3. Chimney and Roof Maintenance

Ensure that your home’s chimneys have tight-fitting caps installed. This prevents flying squirrels from entering through these openings. Replace any broken or missing roof shingles to eliminate potential access points.

4. Secure Vents

Inspect all vents leading into your home, such as dryer vents and bathroom vents. Install tight-fitting covers over these vents to prevent flying squirrels from entering through the openings.

5. Tree Trimming

Trim any trees that are near your roof or have branches that can provide easy access for flying squirrels. By removing these potential bridges, you make it more difficult for them to reach your home.

6. Remove Food Sources

Remove bird feeders and any other wild animal feeders from your property. These can attract flying squirrels and provide a food source, which may encourage them to stay and inhabit your home.

By implementing these prevention measures, you can effectively deter flying squirrels from choosing your home as their habitat.
