If you’ve just spotted a snake in your garage, the safest move is to back away slowly, close the interior door to your house, and keep children and pets out of the area. Most snakes end up in garages by accident while following prey or seeking shelter from heat, and they generally want to leave as much as you want them gone. What you do next depends on whether you can identify the snake and how comfortable you are handling the situation yourself.
What to Do Right Now
Stay calm and put distance between you and the snake. Don’t try to catch, trap, or kill it. If you can safely do so, take a photo from several feet away. That photo helps with identification and is useful if you end up calling a wildlife professional. Try to note the snake’s color, pattern, size, and head shape while you have eyes on it.
Close the door between the garage and the rest of your house. If the garage has an exterior door or window you can open from a safe angle, do so. Many snakes will leave on their own once they have a clear exit. If the snake is near the garage door, you can try raising it with the opener to give the snake a way out, but only if you can do that without getting closer.
When to Call a Professional
If you can’t identify the snake, treat it as potentially venomous. The New Jersey Division of Fish and Wildlife recommends contacting your local animal control officer (usually reachable through your local police non-emergency line) or a private wildlife control company to catch and relocate any snake you can’t positively identify. If you believe the snake is venomous, photograph it from a safe distance and call your state’s wildlife or environmental protection hotline for assistance.
Even if the snake is clearly non-venomous, calling a professional is a perfectly reasonable choice. Many wildlife removal services will come the same day, and some animal control departments handle snake calls at no cost.
DIY Removal for Non-Venomous Snakes
If you’re confident the snake is non-venomous and you’re comfortable getting closer, there are a couple of approaches. The simplest is to gently guide the snake toward an open door using a long-handled broom, sweeping slowly behind it rather than at it. A startled snake is more likely to hide deeper in clutter than head for the exit.
Another method, recommended by the Internet Center for Wildlife Damage Management, works well for a snake that’s hiding and won’t come out. Place a few piles of damp towels or burlap bags in the area where the snake was last seen, especially near heat sources or dark corners. Cover each pile with a dry towel. Check under the piles after a day or two. Snakes are drawn to the moisture and cover, and once one settles in, you can scoop up the whole bundle with a flat shovel and carry it outside.
If you pick up a non-venomous snake by hand, support its body with your second hand to avoid injuring its spine as it wriggles. Snake tongs are a better option if you have them. Release the snake in a natural area away from your home.
Why Snakes Enter Garages
Snakes aren’t attracted to your garage itself. They’re attracted to what’s inside it or the conditions it creates. The most common draw is prey. Mice and rats love garages, and snakes follow them. If you store pet food, birdseed, or livestock feed in your garage, those attract rodents, which in turn attract snakes. Even spilled seed on the ground is enough to start the chain.
Temperature is the other big factor. During hot, dry stretches, snakes seek cooler shelter. In cooler months, a garage that retains some warmth from a water heater or connected living space becomes appealing. Garages also tend to accumulate the kind of cover snakes prefer: firewood stacks, lumber, cardboard boxes on the floor, and general clutter that creates dark, tight hiding spots.
The entry point is usually the gap beneath the garage door. Even a half-inch gap is enough for smaller species, and most garage doors have uneven gaps that widen at the edges. Cracks in the foundation, gaps around utility pipes, and spaces where weatherstripping has deteriorated also serve as entry points.
How to Snake-Proof Your Garage
Sealing the gap under your garage door is the single most effective step. Garage door threshold seals attach to the floor and press against the bottom of the closed door, eliminating the gap. They come in heights from a quarter inch up to two inches. To pick the right size, measure the gap in several places across the door’s width, since it often varies from one side to the other, and choose a seal that covers the largest gap. The seal should extend about an inch and a half past each side of the door opening so you can notch it around the tracks. These seals also block mice, rats, and insects, which removes the prey that attracts snakes in the first place.
Beyond the door, inspect the garage’s perimeter for cracks or gaps and seal them with caulk, expanding foam, or hardware cloth. Pay attention to where pipes, wires, or conduit enter the walls. Replace any damaged weatherstripping around side doors and windows.
Inside the garage, reduce hiding spots. Store firewood and lumber away from the house. Get boxes off the floor and onto shelving. Eliminate standing water from leaky fixtures or condensation. If you feed pets in the garage, clean up food promptly and store bags in sealed containers. Address any rodent problem directly, because as long as there’s a food source, snakes have a reason to visit.
Snake Repellents Don’t Work
Commercial snake repellents are essentially useless. The North Carolina Wildlife Resources Commission states plainly that numerous studies show these products do not effectively deter snakes. The reason comes down to biology: snakes don’t smell through their nostrils the way mammals do. They flick their tongues to capture air particles and press them against a sensory organ in the roof of their mouth. Strong-smelling substances like mothballs, sulfur, garlic, cinnamon oil, and peppermint oil have no meaningful impact because snakes don’t process scent that way.
Products like Snake-A-Way granules are essentially crushed mothballs. Liquid versions rely on garlic. Other brands use blends of cinnamon, castor, and clove oils. None of them change snake behavior as advertised. Mothballs in particular are not just ineffective but illegal to use outdoors, since their active ingredient (naphthalene) is toxic to pets, wildlife, and people. Skip the repellents and spend that money on a threshold seal and rodent control instead.
If a Snake Gets Stuck on a Glue Trap
Glue traps set for mice frequently catch snakes by accident. If you find a snake stuck to one, you can free it with cooking oil spray. Spray the oil around the areas where the snake’s body is stuck to the trap, avoiding its face. For areas near the head, apply oil with a damp cloth or cotton swab instead of spraying directly. The oil deactivates the glue, but the process takes anywhere from several minutes to an hour. Work the snake free gently as the adhesive loosens. Never pull or peel the snake off the trap, as this tears their skin and scales.
Once the snake is free, check its condition. If it’s active and responsive, release it in a suitable outdoor area nearby. It may still be sticky or oily, but most snakes shed their skin soon after and recover fully. If the snake appears injured or unresponsive, contact a local wildlife rehabilitator. Going forward, consider switching from glue traps to snap traps in your garage if you’re managing a rodent problem, since glue traps catch far more unintended animals than their alternatives.
