What Attracts Mice To Nest In The Garage Or Basement

How to Keep Mice Out of Your Garage (Or Shed)

The primary attraction mice have to your basement or garage is the accessibility to shelter and warmth. Typically a garage door is not sealed very well, or the foundation has cracks. Both are excellent ways for a tiny critter such as a mouse to squeeze into.

Mice begin collecting items to build their nest once they get inside. These nesting items can be anything from old newspapers, cardboard boxes, and any other debris you may have stored away.

As long as the environment is warm and cozy, these critters will hang around in your garage as long as you let them. Additionally, a garage normally has plenty of food sources in it, such as pet food, birdseed, and grass seed will keep them sustained throughout the winter.

Cut Off The Food Supply

You may not think twice about that extra fridge out in the garage or opened bags of fertilizer, straw, grains or pet food, but the mice sure do. Mice will remain in your garage so long as theres food to keep their bellies full and negate the need to hunt outside of the structure.

To prevent mice from seeking shelter in your garage, make sure all of these food sources are properly bagged and stored.

Bags of grain and fertilizer are often flimsy and you might overlook potential holes or tears, and so it is in your best interest to store these mice-attracting food sources in a sealed bin or container.

This goes the same for things that tend to spill easily, like birdseed. Examine the floor of your garage, behind tables, under workbenches, or beneath cluttered areas to see if there are any spills that need to be cleaned up.

Without the supply of food being readily available, this is one reason for mice to not shack up in your garage, and one of the most important ones. As with any animal, a food source isnt what only attracts them to the shelter, but it keeps them sticking around too.

How To Get Rid Of Mice

Mice hanging around in your house is a problem that can rapidly get out of hand. Heres what you need to know about keeping the mammals of the order Rodentia out of your home.

There are a number of strategies to deal with a mouse problem, ranging from prevention to repellent to trapping. Each has its own merits and flaws along with varying degrees of compassion for the mouse itself.

    What Surfaces Can Mice Climb Up

    Mice are able to climb up most surfaces–this includes furniture, stairs, countertops, landscape features, and even most surfaces that are vertical. As long as the wall has something for them to grip their tiny paws onto, mice can scale up.

    Mice are skillful at jumping and climbing. Mice will climb anything that has a rough surface, this means walls made of stucco, wood, or panels.

    Surfaces that are vertical but smooth dont allow the mouse the opportunity for gripping onto anything. This poses an issue when they attempt climbing up the wall. Mice will use ropes, wires, and pipes as aides in climbing up these smooth surfaces. Even that beautiful vine plant you have climbing up the side of your home presents an open invite to mice. Mice are persistent when trying to get indoors, taking advantage of any rough areas. They also see crevices, or cracks in garage doors.

    Block Hiding Places And Small Holes With Steel Wool

    Mice are elusive creatures that can be difficult to eliminate once theyve taken up residence in your home. One of the best ways to prevent mice from moving in is to block their hiding places and small holes with wool. Mice are attracted to homes because they offer shelter, food, and water. By stopping their access to these things, you make it much less likely that theyll want to move in.

    Steel wool is an incredibly effective deterrent because its durable and cant be easily chewed through. Plus, its a more humane solution than traps or poison, which can be dangerous for children and pets. So if youre looking for a way to keep mice out of your garage, wool is a great option.

    Remove All Food Sources

    Mice only need small amounts of food each day. To get rid of them in your home, remove the things they like to eat. Store all grains, pet food, and other dry goods in glass or metal containers, which keep food secure since mice cannot chew through them.

    To avoid attracting mice to your property, seal all potential food sources in tamper-proof bins, avoid leaving pet food out for long periods, and clean up all spills and messes promptly.

    How to Keep Rats & Mice Out of Your Garage

    Mice love to build nests. They do this for multiple reasons, and the more you understand about why they build nests, the better chance you have in getting rid of the infestation. Nesting behavior allows mice to regulate their body temperature, which is especially helpful in your garage during colder nights.

    Building nests also allow mice to protect their litter and young mice pups, giving their offspring a sense of security and protection. Nests also protect the mice against other predators, hiding their bodies in a mess of hay, grass, and other various materials.

    Essentially, nests prolong the survival of the mice, and as soon as you rid your garage of materials these nests can be created out of, the sooner the mice will pack up and vacate your garage.

    Garages have a tendency to collect things that shouldve been thrown away, like pieces of paper, straw that came loose from its binding or packaging that was neglected and not tossed in the garbage.

    All of these items make great material for mice to collect and build nests. Go through your garage and clean up anything that looks like it might make for an excellent bedding material for mice. By doing so, youll not only complete the dreaded task of finally cleaning the garage, but also ensuring the prevention of mice setting in there for good.

    Clean The Garage Floor

    Mice are attracted to cluttered, dirty environments where they can find food, shelter, and other materials. A floor covered in oil and grease is perfect for a mouse to set up camp. Not only will cleaning the floor help prevent mice, but it will also make the space more appealing and functional.

    A clean floor is easier to sweep and mop, and it will dry faster after a rainstorm. In addition, it will be easier to spot signs of mouse activity, such as droppings or gnaw marks. By taking the time to clean the garage floor, you can help deter mice from making themselves at home.

    What Do Mice Look Like

    The mice that commonly infest a home or garage include a number of species in the Mus genus of the Rodentia order of mammals. These small, fairly innocuous creatures are common visitors to human homes simply because these structures offer them the dark sheltering areas and food supply they need to survive. Garages are especially susceptible to infestations because mice often go overlooked here. And food sources, such as grass seeds, bird food, and pet food, are often plentiful.

    The best-known species of mouse in the U.S. is Mus musculus, the 3- to 4-inch-long brownish house mouse with a pointed nose and long tail. There are also a number of field mice from the Apodemus genus and deer mice from the Peromyscus genus that can, under some circumstances, infest a home, garage, or outbuilding. These rodents are very similar to house mice, except for having white bellies rather than the solid-colored coat found on the house mouse.

    • Keep grass seed, dog food, and bird seed in sealed containers or bins
    • Reduce clutter and keep things organized
    • Seal cracks and gaps leading into the garage
    • Cut back tree branches that touch the roof of the garage
    • Move trashcans outdoors and seal them tightly

    One of the most important things you need to do to prevent mice from entering your garage is to completely seal entry points. Mice can squeeze through a gap as small as a dime. Dont underestimate a mouses determination to use these holes and enter your garage! Remember, just because you dont see actual mice doesnt mean they arent there in large numbers. Just one mouse can have between 25-60 offspring in a single year.

    Option Three: The Circle Of Life

    If relocating your mice isnt really an option, or if its a recurring problem, it might be worth adopting a cat. Cats make excellent family pets, and their presence is an active deterrent to rodents. Mice tend to avoid nesting in areas where they know active predators are present, but its important to remember that cats are simply a deterrent and not a solution to why you might have pests. Having a cat can be a wonderful addition to your family, but if youre not ready for the commitment of a pet, its better to revisit the preventative solutions.
