If you’ve noticed unusual noises in your ceiling during a cold Oakville winter, especially near areas like Lakeside Park or the shores of Lake Ontario, you’re not alone. Raccoons entering attics in search of warmth are a growing problem for local homeowners. 

These animals can cause serious damage to insulation by tearing it apart to create nests, reducing its effectiveness and forcing you to replace it. They also chew on wiring, which can create fire hazards and costly electrical repairs. 

At Skedaddle, we help Oakville residents understand these risks and take the necessary steps to prevent raccoons from entering attics, as well as safely repair any damage, protecting both your home and your family’s health.

Why Raccoons Seek Shelter in Attics During Winter

Winter in Oakville can bring freezing temperatures and harsh weather. Raccoons, being highly adaptable and clever, do not hibernate but instead enter a low-activity state known as torpor. During this period, they actively seek warm, protected refuges—attics are among their top choices. These spaces offer safety from the cold and suitable conditions for raising young when spring arrives.

Raccoons are drawn to:

• Insulation that provides warmth and nesting material
• Soft or damaged entry points, such as soffits, vents, and rooflines
• Shelter from predators and the elements

Their dexterity allows them to tear through building materials, even under harsh conditions, quickly transforming a small gap into a larger entryway, making Oakville’s older homes particularly vulnerable.

In understanding why raccoons choose attics, it’s crucial to see how these actions lead to broader issues that affect both home infrastructure and health.

How Raccoons Cause Insulation Damage and Wiring Hazard

Understanding insulation damage caused by raccoons during cold weather is crucial for any Oakville homeowner wanting to stay ahead of surprise repair costs and energy loss. When these animals enter your attic, their need for comfort and nesting space leads them to disturb and destroy insulation, as well as impact other critical components of your home.

Typical Damage from Raccoons in Attics

During our winter inspections, our team consistently observes significant attic damage caused by wildlife. Insulation is often trampled, compacted, or shredded, with sections pulled apart or removed entirely for nest-building. In many cases, insulation becomes saturated with urine and feces, resulting in a loss of thermal efficiency (R-value) and unpleasant odours. Additionally, entry holes created by animals can allow snow, rain, and damp air to enter the attic, further compromising your home’s structure and comfort.

The result is increased home heating bills, uneven indoor temperatures, and often the need for costly attic restoration.

Broader Implications: Health Risks from Raccoon Infestations

While the physical destruction is alarming, it’s only part of the story. The presence of raccoons in your attic significantly increases health risks to everyone living in the home, particularly during the enclosed winter months.

Dangerous Consequences of Raccoon Droppings and Urine

Raccoon droppings and urine can introduce multiple disease risks, aggravating pre-existing allergies and causing more serious health problems:

• Leptospirosis, which can result in severe flu-like symptoms or organ damage
• Salmonella spreads through contaminated surfaces, leading to gastrointestinal illness
• Baylisascaris procyonis (raccoon roundworm), a parasite in raccoon feces that can cause severe neurological diseases in humans and pets
• Giardiasis affects the digestive system through contaminated dust and surfaces
• Airborne bacteria from dried droppings can circulate via your home’s HVAC system

These health risks underscore the importance of thorough contamination cleanup in addition to raccoon removal itself.

As we discuss the dangers, it’s essential to recognize how Skedaddle’s process is designed to address every aspect of the infestation, including thorough decontamination.

How Skedaddle Humanely Resolves Raccoon Attic Damage in Winter

Dealing with raccoon attic damage requires a methodical, expert approach. Our Oakville team at Skedaddle follows a tested, humane, and comprehensive process to protect your home and your health.

Our Attic Damage Control & Restoration Process

With over 30 years in wildlife control, we’ve structured our removal and repair strategy to provide the deepest protection and peace of mind:

1. Complete property assessment—identifying every raccoon entry point and inspecting for hidden damage or contamination.
2. Hands-on removal—using thermal imaging to locate raccoons and their babies, ensuring safe and gentle extraction.
3. Securing the structure—sealing all entry points using heavy-gauge screening that raccoons cannot tear through.
4. Cleanup and decontamination—removing soiled insulation, feces, and urine, then deodorizing affected areas.
5. Insulation restoration—replacing contaminated or destroyed materials to restore your home’s energy efficiency and comfort.

This approach is designed to tackle multiple concerns, including all areas of existing damage, immediate and long-term health hazards, and the risk of future infestations. Our ultimate goal is to keep your family safe without harming the animals and to ensure lasting results.

The Most Common Signs of Raccoon Activity and Damage

Noticing the signs of raccoon activity quickly can save Oakville homeowners from mounting repair bills. Based on our years of operating near Oakville landmarks such as the Museum and busy neighbourhoods, here are the warning signals to watch for, especially as winter deepens:

• Strange scratching or thumping noises overhead at night
• Increased cold spots or drafts in the home (due to insulation disruption)
• Notable odours in the upper floors or living spaces
• Visible holes near rooflines, vents, or soffits
• Stains, debris, or droppings in the attic

If you spot any of these signs, timely action is crucial before problems escalate.

Recognizing these signs early and taking action is vital to preventing further damage and health risks.

Prevention Tips: Keeping Raccoons Out Year-Round

Proactive prevention is the key to long-lasting home protection—especially before the temperature drops and raccoons seek shelter. Skedaddle’s specialists are ready to advise Oakville homeowners on best practices and advanced solutions to secure your attic.

Top Raccoon Prevention Tips

To reduce the risk of raccoons damaging your attic and its wiring, we suggest the following actions:

• Inspect your roof, soffits, and vents for any damage or weak spots before winter arrives
• Repair or reinforce vulnerable areas using wildlife-proof materials
• Store garbage and compost bins securely; raccoons are less likely to linger without reliable food sources
• Trim tree branches close to the roof—these act as natural bridges for raccoons
• Book a thorough attic assessment, especially after a previous wildlife entry or unexplained sounds

These steps greatly reduce your odds of facing major insulation damage or wiring issues that become apparent only once the snow falls.

Relying on professional inspection ensures hidden entry points and minor issues are addressed—often before you’d ever notice a raccoon’s presence.
