Understanding Squirrels in Wisconsin

Squirrels are common in Wisconsin, known for their agility and bushy tails. While they are enjoyable to watch in nature, their presence in homes and buildings can lead to significant problems. Understanding where squirrels are typically found, what attracts them to indoor environments, and why they are unsuitable for homes and buildings is essential for effective management and prevention.

Common Squirrel Species in Wisconsin

Wisconsin is home to several species of squirrels, including:

Eastern Gray Squirrel (Sciurus carolinensis): The most common squirrel in urban and suburban areas, gray squirrels are adaptable and often seen in parks and gardens.

Fox Squirrel (Sciurus niger): Larger than gray squirrels, fox squirrels prefer open woodlands and are also common in urban areas.

Red Squirrel (Tamiasciurus hudsonicus): Smaller and more aggressive, red squirrels are often found in coniferous forests.

Southern Flying Squirrel (Glaucomys volans): Nocturnal and less commonly seen, flying squirrels glide between trees and are found in deciduous forests.

Habitats and Locations

Squirrels in Wisconsin are typically found in:

Outdoors:

Woodlands and Forests: Squirrels thrive in wooded areas with abundant tree cover and food sources like nuts and seeds.

Urban and Suburban Areas: Parks, gardens, and backyards provide ample food and nesting sites for squirrels.

Near Water Sources: Areas near streams, rivers, and lakes offer both food and water, attracting squirrels.

Indoors:

Attics and Garages: Squirrels may enter attics and garages seeking shelter and nesting sites, especially during colder months.

Chimneys: Unused chimneys can become attractive nesting sites for squirrels.

Wall Voids and Eaves: Squirrels can find their way into wall voids and eaves, creating nests and causing damage.

Attractions in Homes and Buildings

Squirrels are attracted to homes and buildings for several reasons:

Food Sources: Squirrels are drawn to bird feeders, pet food, garbage, and accessible food stored in homes.

Shelter: Homes provide warm, protected environments ideal for nesting and raising young, especially during winter.

Nesting Materials: Squirrels are attracted to insulation, fabric, and other materials they can use to build nests.

Why Squirrels Are Not Suitable for Homes and Buildings

While squirrels are beneficial in natural ecosystems, their presence indoors is highly undesirable for several reasons:

Property Damage:

Chewing and Gnawing: Squirrels constantly gnaw on wood, electrical wiring, insulation, and other materials, which can cause significant structural damage and create fire hazards.

Nesting: Squirrels can tear up insulation, fabric, and other materials to build nests, leading to damage and increased energy costs.

Health Risks:

Disease Transmission: Squirrels can carry diseases such as leptospirosis, salmonella, and rabies, which can be transmitted to humans and pets through bites, scratches, or contact with droppings.

Parasites: Squirrels often harbor fleas, ticks, and mites, which can infest homes and pose additional health risks.

Nuisance:

Noise: Squirrels can create significant noise in attics and walls, especially when they are active during the early morning and evening hours.

Contamination: Squirrel droppings and urine can contaminate living spaces, creating unpleasant odors and unsanitary conditions.

Prevention and Control

To prevent and control squirrel infestations in homes and buildings, consider the following strategies:

Seal Entry Points:

Caulk Cracks and Gaps: Inspect and seal any cracks and gaps around windows, doors, roofs, and foundations to prevent squirrels from entering.

Install Chimney Caps: Use chimney caps to prevent squirrels from entering through chimneys.

Use Hardware Cloth: Cover vents, soffits, and other potential entry points with hardware cloth or wire mesh to block access.

Remove Food Sources:

Secure Garbage: Use tightly sealed trash bins and dispose of garbage regularly to reduce food sources for squirrels.

Bird Feeder Management: Place bird feeders away from the house and use squirrel-proof feeders to minimize attraction.

Store Food Properly: Store pet food and other attractants in airtight containers.

Trim Trees and Vegetation:

Tree Trimming: Trim tree branches that overhang or are close to the house to prevent squirrels from accessing the roof.

Remove Debris: Clear away piles of leaves, wood, and other debris that can provide cover and nesting materials.

Use Repellents:

Natural Repellents: Use natural squirrel repellents, such as cayenne pepper, peppermint oil, or predator urine, around potential entry points.

Commercial Repellents: Consider using commercial squirrel repellents, following all safety guidelines and instructions.
