Keep Raccoons Out of Your Home: Expert Prevention Tips

You wake up to the sound of scratching in your attic. The next morning, you find your trash scattered across the lawn and fresh paw prints leading up to your roof. If this sounds familiar, you’re likely dealing with raccoons—one of Southern Ontario’s most persistent and intelligent wildlife visitors.

While raccoons might seem harmless from a distance, these masked bandits can cause serious damage to your home and pose health risks to your family. The good news? With the right prevention strategies, you can keep these nocturnal nuisances away from your property for good.

In this guide, we’ll walk you through everything you need to know about raccoon prevention, from understanding what attracts them to your home to implementing effective exclusion methods that actually work.

Why Raccoons Target Your Home

Before you can effectively keep raccoons away, it’s important to understand what draws them to your property in the first place. Raccoons aren’t randomly choosing your home—they’re responding to specific attractants and opportunities.

Raccoons are opportunistic feeders with an incredible sense of smell. They can detect food from miles away, and once they’ve identified your property as a food source, they’ll keep coming back. Common attractants include unsecured garbage bins, pet food left outdoors, bird feeders, compost piles, and even fruit trees or vegetable gardens.

Beyond food, raccoons are constantly searching for safe, warm places to nest, especially during breeding season (typically late winter to early spring). Your attic, chimney, or crawl space provides the perfect den—protected from predators and the elements. Even a small vulnerability in your roof, soffit, or foundation can become an invitation for these skilled climbers.

Signs Raccoons Are Targeting Your Property

Early detection is key to preventing a full-blown infestation. Watch for these telltale signs that raccoons have set their sights on your home:

• Overturned garbage bins: Lids removed or bins tipped over, with trash scattered around your property
• Paw prints: Five-toed tracks resembling small human hands in mud, snow, or around entry points
• Scratching or thumping noises: Especially at night, coming from your attic, walls, or chimney
• Damaged roof components: Torn shingles, damaged soffit vents, or holes near the roofline
• Strong musky odor: A distinctive, pungent smell near potential entry points or in your attic
• Visible droppings: Dark, tubular feces often found on your roof, deck, or near food sources
• Garden destruction: Dug-up lawns (searching for grubs), damaged vegetables, or eaten fruit

If you’re noticing any of these signs, it’s time to take action. For help identifying the extent of the problem, consider scheduling a professional wildlife inspection to assess your property’s vulnerabilities.

Proven Strategies to Keep Raccoons Away

1. Secure Your Garbage and Food Sources

Your first line of defense is eliminating the food sources that attract raccoons to your property. This means being proactive about how you store and manage anything edible.

Invest in garbage bins with locking lids or secure existing lids with bungee cords or straps. If possible, store your bins in a garage or shed until collection day. Never leave trash bags outside overnight—raccoons can easily tear through plastic to access food.

Remove pet food bowls from outdoor areas after feeding time. Don’t leave water dishes outside either, as raccoons are attracted to water sources. If you have a bird feeder, consider bringing it in at night or switching to raccoon-proof designs. Similarly, secure your compost bin with a locking lid or keep it in an enclosed area.

If you have fruit trees or a vegetable garden, harvest produce promptly and clean up fallen fruit regularly. Raccoons are particularly fond of corn, berries, and soft fruits.

2. Seal Entry Points and Vulnerable Areas

Raccoons can squeeze through surprisingly small openings—any gap 4 inches or larger is fair game. A thorough inspection and sealing of your home’s exterior is essential for long-term prevention.

Start with a careful walk around your property, paying close attention to:

• Roof edges, shingles, and eaves
• Soffit and fascia boards
• Roof vents and exhaust fans
• Chimney tops (install a cap if you don’t have one)
• Gaps where utilities enter your home
• Foundation cracks and crawl space openings
• Attic vents and louvers

Use heavy-gauge steel mesh or hardware cloth to cover vents and openings. For gaps and cracks, use metal flashing, caulk, or expanding foam (though note that raccoons can chew through foam, so it’s best reinforced with metal). Make sure to only seal entry points after you’re absolutely certain no raccoons are currently inside—trapping them could lead to desperate escape attempts and even more damage.

For comprehensive protection, professional sealing and preventative services can identify and secure all potential entry points, giving you peace of mind that your home is fully protected.

3. Install Physical Barriers and Deterrents

Creating physical obstacles makes it harder for raccoons to access your home and reduces the appeal of your property.

Trim tree branches that hang within 8-10 feet of your roof. Raccoons are excellent climbers and will use overhanging branches as highways to your roofline. Similarly, move woodpiles, debris, and outdoor furniture away from your home’s exterior—these can serve as stepping stones to higher access points.

Consider installing barriers around areas you want to protect. A sturdy fence (at least 4 feet high) can help keep raccoons out of gardens. For added effectiveness, add a “floppy” extension at the top—when raccoons try to climb over, the unstable top section will cause them to fall back down.

Wrap the trunks of trees near your home with smooth metal sheeting or plastic guards to prevent raccoons from climbing. This is particularly important if you have trees close to your roof or areas you’re trying to protect.

4. Use Light and Sound Deterrents

Raccoons are nocturnal creatures that prefer dark, quiet environments. You can exploit this behavior to make your property less appealing.

Install motion-activated lights around vulnerable areas like garbage storage, entry points, and the perimeter of your home. The sudden illumination will startle raccoons and make them feel exposed. Motion-activated sprinklers work on the same principle and have the added benefit of creating an unpleasant experience that raccoons will want to avoid.

Some homeowners have success with motion-activated ultrasonic devices or radios left on talk stations (the human voices can suggest activity). However, these methods tend to work best as short-term solutions—raccoons are smart and may eventually habituate to sounds that pose no real threat.

5. Remove Shelter Opportunities

Making your property less hospitable means eliminating potential den sites and hiding places.

Keep your lawn well-maintained with regularly mowed grass and minimal overgrowth. Raccoons prefer properties with plenty of cover where they can move about undetected. Clear away brush piles, dense shrubs near the house, and any cluttered areas that could serve as hiding spots.

Secure sheds, garages, and outbuildings. Make sure doors close tightly and consider adding locks or latches. Check underneath decks and porches—these are prime denning locations. Install lattice or hardware cloth barriers to prevent access to these spaces.

6. Maintain Your Property Regularly

Consistent property maintenance is one of the most effective long-term prevention strategies. Regular upkeep means you’ll catch problems early before they become major access points.

Inspect your roof, siding, and foundation seasonally, looking for new gaps, loose materials, or damage. Raccoons are persistent and may test previously secured areas or find new vulnerabilities. Fix issues promptly—a small hole will only get bigger if a raccoon decides to work at it.

Keep your gutters clean and in good repair. Clogged gutters can cause water damage that weakens roofing materials, creating easier entry points. They can also attract raccoons looking for water or insects.

What NOT to Do When Preventing Raccoon Problems

While you’re working to keep raccoons away, avoid these common mistakes that can make the problem worse or create new issues:

Don’t use poison or inhumane methods. Beyond being cruel, poisoning raccoons is illegal in Ontario and can pose serious risks to pets, children, and other wildlife. Dead raccoons in inaccessible areas also create terrible odors and health hazards.

Don’t attempt to trap and relocate raccoons yourself. Ontario law prohibits relocating trapped raccoons more than one kilometer from where they were captured. Beyond the legal issues, relocation is inhumane—raccoons relocated to unfamiliar territory face starvation, territorial conflicts, and separation from dependent young.

Don’t seal entry points without ensuring all raccoons are out. If you trap a raccoon inside, it will cause significant damage trying to escape. Even worse, if a mother raccoon is separated from her babies inside, she may cause severe damage trying to get back to them.

Don’t approach or attempt to handle raccoons. Raccoons can be aggressive when threatened and may carry diseases including rabies. Keep your distance and never corner a raccoon.

When to Call a Professional Wildlife Control Expert

While DIY prevention methods can be effective, there are situations where professional help is the smarter, safer choice.

Consider calling a professional if:

• You’ve implemented prevention strategies but raccoons keep returning
• You hear raccoons in your attic, walls, or chimney
• You’ve found visible entry points but aren’t sure how to properly seal them
• You suspect there may be baby raccoons on your property (typically spring and early summer)
• Raccoons have caused structural damage that needs repair
• You’re uncomfortable working at heights or handling wildlife situations
• You want a comprehensive inspection to identify all vulnerabilities

Professional wildlife control specialists have the experience, equipment, and knowledge to handle raccoon problems safely and effectively. They can identify entry points you might miss, use humane exclusion methods like one-way doors, and ensure your home is properly protected against future intrusions.

The Importance of Year-Round Prevention

Raccoon prevention isn’t a one-time task—it’s an ongoing commitment to property maintenance and vigilance. Raccoons are active year-round, though their behavior changes with the seasons.

In spring and summer, raccoons are breeding and raising young. This is when they’re most desperate for den sites and food. They’ll be particularly aggressive about accessing attics and other protected spaces. During fall, raccoons are preparing for winter by eating heavily and finding suitable winter dens. Winter brings less activity, but raccoons don’t truly hibernate—they’ll still emerge on warmer days to search for food.

By maintaining your prevention strategies throughout the year, you’ll be ready for whatever raccoon behavior each season brings. Regular inspections, consistent food source management, and prompt repairs will keep your property protected no matter what time of year it is.

Additional Wildlife Concerns

While this guide focuses on raccoons, many of the same prevention strategies work for other wildlife species common to Southern Ontario. If you’re dealing with raccoons, you may also encounter issues with squirrels, skunks, or other animals.

Squirrels, for instance, are also excellent climbers that target attics and can cause similar damage through chewing and nesting. Skunks typically den under decks and sheds. The good news is that comprehensive wildlife-proofing addresses vulnerabilities that multiple species could exploit.

For comprehensive wildlife control services throughout Southern Ontario, our team can help with a wide range of wildlife situations.
