If you've been hearing frantic scratching sounds above your car or finding piles of acorns in your storage bins, you're likely looking for how to get rid of red squirrels in garage spaces before they do some real damage. These little guys might look cute with their reddish fur and tufted ears, but they are surprisingly destructive and incredibly territorial. Unlike the larger gray squirrels, red squirrels are smaller, faster, and much more aggressive when it comes to defending their "territory"—which, unfortunately, is now your garage.
Getting them out isn't just about peace and quiet; it's about protecting your home. Red squirrels love to chew on everything from wooden rafters to electrical wiring, which can create a serious fire hazard. If you've realized you have a roommate you didn't ask for, it's time to take action.
Why Red Squirrels Love Your Garage
Before we jump into the "how-to," it helps to understand why they chose your garage in the first place. Red squirrels are natural hoarders. They love dry, secluded spots where they can store their winter stash of pinecones and nuts. Your garage offers the perfect environment: it's warmer than the outdoors, it's protected from predators like hawks and foxes, and it's usually full of "nesting material" like cardboard boxes, old blankets, or fiberglass insulation.
Once they find a small gap—sometimes as tiny as a quarter—they'll squeeze through or gnaw at it until it's big enough to fit. Once they're in, they aren't planning on leaving voluntarily. They are creatures of habit, and if they feel safe, they'll start a family right there next to your Christmas decorations.
Step 1: Find the Entry Points
You can't solve the problem if you don't know how they're getting in. Put on your detective hat and walk around the perimeter of your garage. Look for holes near the eaves, gaps in the siding, or places where the garage door doesn't quite meet the pavement.
Pro tip: Look for "rub marks." Squirrels have oils in their fur that leave dark, greasy stains around the holes they use frequently. If you see a hole with some brownish staining around the edges, that's your primary entrance. Also, check for chewed wood around vents or corners. Since their teeth never stop growing, they have to gnaw on things to keep them filed down, and your garage's cedar siding is a perfect whetstone.
Step 2: Use One-Way Doors
One of the most effective and humane ways to handle the situation is using a one-way exclusion door. You can buy these online or at most hardware stores. The concept is simple: you mount the device over the squirrel's main entrance. The squirrel can push its way out to go find food, but the spring-loaded door won't let it back in.
This is much easier than trapping and relocating, which often results in the squirrel dying anyway because it doesn't know where the food sources are in a new territory. With a one-way door, they simply realize they're locked out and eventually move on to a backup nesting site. Just make sure you've sealed every other possible hole first, or they'll just find another way back into the "warm room" within ten minutes.
Step 3: Make the Environment Unbearable
Squirrels love your garage because it's quiet, dark, and safe. If you want to know how to get rid of red squirrels in garage areas without immediate construction, you have to ruin their vibe. You need to make the garage the most annoying place on earth for a squirrel.
Bright Lights
Red squirrels are technically diurnal (active during the day), but they hate sleeping in bright light. Buy a cheap LED strobe light or just leave a few high-wattage shop lights on 24/7 for a few days. The constant brightness makes them feel exposed and vulnerable, which usually prompts them to move their nest elsewhere.
Noise Pollution
Grab an old radio and tune it to a talk-back station. The sound of human voices is a huge deterrent. Keep the volume loud enough that it's audible throughout the garage. If they think humans are constantly hanging out in there, they'll get nervous and pack their bags.
Scent Repellents
While not always a permanent fix, scents can help push them out. Red squirrels have a very sensitive sense of smell. Soaking cotton balls in peppermint oil or apple cider vinegar and placing them near the nest can be effective. Some people swear by using predator urine (like fox or coyote urine, which you can buy at sporting goods stores), but be warned: your garage will smell like a zoo for a while.
Step 4: The Clean-Up and Eviction
Wait! Before you seal those holes permanently, you have to be absolutely sure the squirrels are actually out. If you seal a mother red squirrel out while her babies are inside, she will tear your garage apart trying to get back to them. Worse, if you seal them inside, they will die, and the smell will be something you'll regret for months.
A good trick to see if a hole is still in use is the "newspaper test." Stuff a piece of crumpled newspaper loosely into the hole. If it's still there 48 to 72 hours later, the squirrel has likely moved on. If it's been pushed out, you've still got a tenant.
Step 5: Sealing the Garage for Good
Once you're sure they're gone, it's time for the "permanent" part of how to get rid of red squirrels in garage spaces. You need materials that they can't chew through. Standard caulk or expanding spray foam won't cut it—squirrels eat that stuff for breakfast.
Use heavy-duty hardware cloth (metal mesh) or galvanized steel flashing. Screw it directly over the holes. If you have gaps in your garage door seal, replace the rubber gasket at the bottom and consider adding a metal threshold. If there are holes in the wood siding, fill them with steel wool first, then cover them with wood filler or a metal plate. They hate the feeling of steel wool on their teeth and will usually give up.
Step 6: Eliminate the "Roadways"
Squirrels aren't jumping from the ground to your roof; they're using "highways." Look for tree branches that hang within 6 to 10 feet of your garage roof. Red squirrels are Olympic-level jumpers. If a branch is close, they'll use it to access your eaves.
Trimming back trees so there's at least an 8-foot gap between the branch and the structure will make it much harder for them to get on top of the garage. Also, check your power lines. If they're using the lines to get to the roof, you can buy plastic "sleeves" that spin when a squirrel steps on them, dumping them off (safely) before they reach your building.
When to Call in the Professionals
Sometimes, despite your best efforts, you might have a particularly stubborn red squirrel or a massive infestation that's beyond a DIY fix. If you've tried the lights, the one-way doors, and the sealing, but you still hear that rhythmic gnawing at 6:00 AM, it might be time to call a wildlife removal expert.
Professional removers have specialized thermal cameras to find nests hidden deep inside walls and the equipment to reach high eaves safely. It's an extra cost, sure, but it's cheaper than rewiring your entire garage after a squirrel chews through a main power line.
Keeping Them Away Long-Term
Getting them out is only half the battle; keeping them out is the other half. The biggest mistake people make is leaving food sources nearby. If you have a bird feeder right next to the garage, you're basically inviting the squirrels to a buffet and offering them a hotel room next door.
Keep bird feeders at least 20 feet away from the garage, and use squirrel-proof versions. Also, make sure your trash cans are tightly sealed and that you aren't storing grass seed or pet food in thin plastic bags. Switch to metal bins with locking lids for anything edible.
Red squirrels are persistent, but you can be more persistent. It takes a bit of vigilance and some manual labor, but once you've secured your space, you can finally go back to using your garage for cars and tools instead of a high-end squirrel sanctuary. Just remember: stay consistent, check your seals often, and don't let those "cute" faces fool you—they're tiny demolition experts!
