Gutters are designed to protect your home by directing rainwater away from your foundation, roof, and siding.
However, they also serve as an unintentional playground for a variety of critters—especially squirrels. While these furry acrobats might seem harmless, their presence in your gutters can lead to significant damage, costly repairs, and even potential safety hazards. If you’ve ever wondered, “Can squirrels eat through gutters?” or “What’s hiding in my gutters after winter?”—you’re in the right place. Let’s dive into the problems squirrels cause and how to keep them at bay.
Are Squirrels Able To Eat Through Gutters?
Squirrels aren’t just cute creatures scurrying across your yard—they’re also skilled climbers and relentless chewers. These animals have teeth that continuously grow, meaning they want to gnaw on various materials to keep them at a manageable length.
Unfortunately, your home’s gutters, eaves, and downspouts often become their chewing targets. Even aluminum gutters aren’t safe, as squirrels can easily bite through them, leading to cracks, holes, and eventual leaks.
Squirrels use gutters as both a shelter and a tool. They climb up drainage pipes, scurry onto rooftops, and explore gutter systems in search of safety from predators. If they find a comfortable spot filled with leaves and other nesting materials, they might decide to set up a temporary home—especially during breeding season.
Once a squirrel gets comfortable in your gutters, it can create further problems by building nests with leaves, twigs, and other debris, clogging the drainage system. Over time, this can result in water overflow, which can damage your home’s foundation, cause roof leaks, and create the perfect breeding ground for mold.
Will Gutter Guards Keep Squirrels Out?
One of the most effective ways to prevent squirrels from turning your gutters into their new home is by installing gutter guards. These protective coverings help keep debris, twigs, and other nesting materials out, making the area less appealing for squirrels.
However, not all gutter guards are foolproof. Some squirrels have been known to chew through plastic mesh guards or find small openings to squeeze through.
For the best results, choose a durable, metal gutter guard system that completely covers the opening of your gutters while still allowing water to flow through.
Combined with regular gutter maintenance, these guards can significantly reduce the risk of squirrel damage.
How to Prevent Squirrels from Damaging Your Gutters
Squirrels are persistent creatures, but there are several ways to keep them away from your gutters and prevent long-term damage:
1. Trim Tree Branches
Overhanging tree branches serve as a highway for squirrels to access your roof. Trim branches so they are at least 15 feet away from your house. This makes it more difficult for squirrels to jump onto your home.
2. Clean Your Gutters Regularly
Gutters filled with leaves and twigs attract squirrels looking for nesting materials. Cleaning your gutters at least twice a year, especially after winter, ensures that there’s nothing for them to build a home with.
3. Install Gutter Wire Toppers
These wire coverings help keep debris and pests out of your gutters. They also act as a physical barrier to prevent squirrels from entering.
4. Use Natural Deterrents
Squirrels have sensitive noses and dislike strong odours. Consider placing mothballs inside your gutters (but be cautious, as they are toxic to pets and children). You can also sprinkle cayenne pepper, garlic powder, or predator urine around your roofline to deter squirrels.
5. Use a Squirrel Trap
If you already have squirrels in your gutters, set up a humane squirrel trap on your roof. Bait the trap with peanut butter, then call your local animal control service to safely remove the squirrel.
6. Call Pest Control if Necessary
If squirrels continue to return despite your efforts, professional pest control services can place specialized traps and identify additional entry points that you may have missed.
What Materials Can Squirrels Chew Through?
Squirrels have strong teeth capable of chewing through:
- Aluminum gutters, siding, and downspouts
- Wooden eaves, fascia, and windowsills
- Plastic vent covers and roofing materials
- Electrical wiring (posing a fire hazard!)
However, they cannot chew through galvanized steel or stainless steel. If you suspect squirrels are entering your attic, secure entry points with galvanized steel sheeting or heavy mesh wire after ensuring all squirrels are gone.
Does Aluminum Foil Deter Squirrels?
There’s some debate about whether aluminum foil is an effective squirrel deterrent. Some homeowners claim that squirrels dislike the shininess and crinkling noise of foil, while others report that determined squirrels will chew through it anyway. While it may work as a temporary measure, it’s not a long-term solution.
Protecting Your Home Beyond the Gutters
If squirrels are causing problems beyond your gutters, such as raiding your garden or sneaking into your attic, here are a few additional deterrents:
- Use predator urine sprays to create a natural barrier.
- Plant strong-smelling flowers like marigolds or mustard plants around your yard.
- Scatter dog or human hair around your garden beds.
- Encourage natural predators—if you have a dog, letting them patrol the yard can scare squirrels away.
Final Thoughts
Squirrels may seem harmless at first, but they can cause extensive damage to your gutters, roof, and home if left unchecked. Regular gutter maintenance, strategic deterrents, and professional intervention (if needed) can help protect your home from these persistent critters. By taking proactive steps now, you can ensure your gutters remain functional and free from unwelcome guests for years to come.
