Remove Clutter

Mice love clutter. Whether it’s finding hidden places to burrow or stored pet food or birdseed to eat, clutter means potential hiding spots and potential food. Keeping a clean garage makes is less desirable to mice.

Make sure to store anything the mice could consume in hard plastic containers, and if possible, try storing items off the ground (see below).

There is no nutritional value in the bacteria that grow in the soil. The mice need the landscape’s micro-organisms to make energy for their own growth. Driving them dirty and unsanitary can cut off food from the plants that are replenishing the soils.

Become a ¡Vegetarian!

Chicken is not the only animal that is killed and eaten in this way, but it’s the most frequent victim.
Driving food into the soot that feeds the so-called “giant ant,” which has been reported to eat 80 percent of all animal carcasses. This type of exploitation is known as “egg-eating” or the “Giant Ant Slaughter.” Chicken consumption accounts for almost half the total consumption in this country. In fact, consumption of dairy products by the largest consumers makes up more than half of total food sales.
Macaroni and cheese are the primary foodstuff for ant-attacking mice. Humans also eat their favorite foodstyles on a daily basis, but these may not be crucial to the health of mice’s digestive systems.
Wild oral (insect-eaters) have been noted to feed on several species of grubs and soil-eaten fungi; these animals did not appear to eat the ant, but the same cannot be said for the honeybees.
Ant-insector consumption can lead to serious health and environmental damage. Insects are apt carriers of disease, and some bacterial infections can occur in the intestines, even if foods are removed and recycled, as they die and evaporate. Diseases resulting from vertically integrated agriculture and factory farming, as well as all forms of fermentation, have been shown to occur in mice lunched on organic produce.
Eating insect pests, or bacterium-causing foods, such as the soybean crop, increases the ris

Keep Trash Sealed or Covered

It’s best not to store trash in your garage, but if you do, be sure that the trash cans have tight sealing lids. You’ll also want to be sure there are no holes or cracks in the trash container. Car dumping is illegal in New York City, so if you want to keep the garage free of trash, make sure you have the proper permits. If you want a square foot for your garbage, allow yourself a few square feet.

The trash can is huge, but not impossible to process. You can take an old towel and wipe up all the water so that you don’t see blood-covered clothing on the floor. You could also use a few large pieces of plastic to re-use as tubes for the garbaging needs of your house.
It’ll take a few minutes to wash each piece of clothing, and the garment will be clean enough to be trashed later. This cleanser may not be completely airtight, but it’ll help disperse odors, such as floral, odorant, or synthetic perfumes.

Seal Up Entry Points

Did you know that most mice only need a quarter of an inch to squeeze through an opening? Check the perimeter for any cracks or openings and seal them to prevent mice from being able to squeeze through.

  1. Follow guidelines to ensure your furniture is secure. The easiest way to prevent a mouse from escaping is to keep furnishings secure. Use a spare lock or a gun safe to lock duct tape off the outside, but keep an eye out for mice until the tape is removed.
    Slotted-out wood or some plastic can be hidden by small plastic platters or lined with paper.
    Check the floor space around furnishing and clean the routes where dirt is used as a pad.
    Place a magazine-thick foam between the floor and furnace. Mice can be caught by falling foams.
    If your foaming is in that direction, place a small foamer in that place (periodically flushing it to remove bubbles or dirt).
    Page over foampers or jacks that are lining the sides of the furnaces. Duct tapes can also become an opening.
    Instead of useing bulky glue, use duct clamps to secure the tanks and straws.
    Don’t use a clamp to lift out the tank that holds gas. It can break the tube and force the gas out.
    Please see Gasps on the DIY furnucopia.
  2. Check your folding furnitsure and note how it is sized. Folds should fit about the same as it should be in a furnished apartment.
  3. Clean your foolproof room for air, food, water and/or cleaning supplies. Canned food or other food items should be stored in plastic, plywood or other soft materials that can be swept away after use. Cheaper furnishes should have a small opening in one of the sides to allow light to pass through. For stored equipment check the dimensions of the safe storage area before you place it in the folder.

How to Help Keep Mice Out of Storage Boxes

While it’s common to store items in plastic containers to help keep pests from getting in, if a rat wants what’s in your storage container, it will likely find a way to get in regardless of the material. This is why it’s important to strategically use rodent control methods, like traps and baits, where you store important items. You should also consider having your attic sealed to exclude rodents from getting in there, as that is where many people store things.

For a stronger defense, place items that smell like a cat or dog near vulnerable areas of your garage. If you don’t have a pet, use mothballs or peppermint oil.


Mice enter human buildings looking for the combination of resources necessary to maintain a mouse nest. These resources include:

While mice may infest any building, these rodents often stick to garages and sheds because they observe fewer humans and less intrusive light there. When left alone with enough resources, mice can create large nests and reproduce quickly, making the severity of an infestation worse.

Mice love to hide in the clutter of our garages.

The best way to get rid of mice is to prevent them from getting into your garage in the first place. There are quite a few ways these pesky rodents may be entering your garage, and you’ll want to take steps to seal and reinforce these areas.

Rodent Guard can be used to fix weather-stripping

  • Garage doors are the simplest and easiest way for mice to get in. If mice have chewed through the weather-stripping on the door, a product like Rodent Guard can help prevent them from getting back in. These guards are made of metal, so mice can’t chew or gnaw their way through.

Vinyl or rubber sweeps or thresholds can also be used to eliminate gaps under the door. Here are two products to fix your garage door if the mice are using it as an entrance point.

Garage Door Thresholds . This is essentially a raised rubber bump that you install at the point where the garage door hits the ground. It helps to close any gaps left by your existing weather stripping. In addition to pests, it is intended to keep out water & wind to help insulate your garage and minimize your heating/cooling bills. Sensible Solutions makes a solid product, just be sure to pick up some Liquid Nails to make sure you have enough cement to attach the threshold to your driveway.

Garage Door Replacement Vinyl can be used to fix the bottom of the door if it has been damaged either by wear or those pesky critters. This works on the metal roll down type doors. The vinyl slots are inserted in the metal track located on the bottom of the door. When selecting the size to buy, be sure to look at the track size as well as the width of the door. A little WD-40 will help make the installation process easier.

Seal dryer vents to keep the critters out.

  • Access holes for plumbing or vents are another possible entryway. Tighten any seals around vents, drains, and pipes to prevent access. A popular vent guard called Deflecto is also a great way to keep mice out of dryer vents.
  • Air conditioners. Check air conditioner connections and make sure they’re tightly sealed. Mice can squeeze through gaps as small as a fingernail, so poorly sealed connections are easy for mice to get through.

Sealing your garage is a great way to prevent rodents from getting in, but how do you get rid of any mice that are already living in your garage? Traps and bait are a simple but effective solution.

There are several dos and don’ts of mouse elimination if you are going to try mouse control on your own.

Many houses are built near fields and vegetation where their natural habitats exist and mice in search of food and shelter become more inclined to enter homes. In New Jersey and Pennsylvania, we experience temperature changes for all seasons compared to southern states that are generally always warm. During the wintertime, mouse activity is extremely high. They seek out shelter, which is often conveniently found in garages. This is especially true for garages that aren’t used very often.

What attracts mice to garages?

Rodents have become very accustom to living side by side with humans, whether we like it or not. The homes and garages that we own provide their tiny bodies with protection from snow, sleet, hail, rain, winds, predators, and freezing conditions. To make matters worse, things we wouldn’t eat are food for mice. For example, bird seed and grass seed kept in garages are frequent targets of mouse consumption.

Mice make their nests in houses where human activity is the lowest. They seek out places where they are least likely to be disturbed to create their nest. A single mouse will create a nest to live and raise pups. Once pups are old enough to live on their own, they leave the nest and create their own nests.

What are the signs that mice are in my garage?

Pictured Above: Mice left droppings under a refrigerator stored in a garage.

Mice constantly eat during their waking hours at night, which is a lot because they are so small. Droppings are left behind and will appear to be black or brown in color and the shape of a grain of rice. Piles of droppings are very common because mice live in large groups. In addition to droppings, you may actually see mice. They crawl along edges of walls, so you probably won’t see them running through the middle of a room.

Dog food, bird seed, lawn seed, or other items kept in easily torn open bags and containers will be consumed by mice if they are in your garage. Look for holes in the bags that look chewed up from where mice entered. Because mice are messy eaters, you could also find seeds strewn throughout the garage.

How can I prevent mice from getting into my garage?

If you want to prevent mice from getting into your garage, you need to make the garage as unappealing to them as possible. Use the following tips to rodent-proof your garage.

  • 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
  • Store firewood outdoors, as far away from your garage and house as possible

Pictured Above: An entry point where the garage stairs meet the exterior wall was allowing mice to infest the garage.

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. Don’t underestimate a mouse’s determination to use these holes and enter your garage! Remember, just because you don’t see actual mice doesn’t mean they aren’t there in large numbers. Just one mouse can have between 25-60 offspring in a single year.

How can I get rid of the mice in my garage on my own?

There are several dos and don’ts of mouse elimination if you are going to try mouse control on your own.


Close off gaps- Use caulk and steel wool to fill in small holes and gaps leading into the garage.

Clean up your garage— Grass seed and dog food strewn around the garage is an endless buffet for mice.

Declutter and reorganize— Don’t keep items in cardboard boxes. Use sealed containers and bins. If there is more floor space open, you have fewer hiding places and a better chance of finding potential nesting spots.

Cut back bushes and plants— By trimming back vegetation that comes into contact with the foundation of your garage, mice will have less space to hide and gather.


X Use sound machines or ultrasonic repellers— They have been proven time and time again to be ineffective.

X Rely on essential oils or scents— Mice are highly adaptable and aren’t deterred by a little bit of peppermint oil when they find a goldmine of bird seed in your garage.

X Trust your cat— Yes, cats can catch mice. However, it’s not a reliable form of pest control when mice are multiplying and infesting.

X Cover your garage in cayenne pepper— Our pest control technicians run into this issue a lot. They are called to a home that has droppings everywhere, including on and around cayenne pepper that was used as a “natural barrier.” If it was this easy to get rid of mice, pest control companies would be out of business.

PETA suggests that every pest can be disposed of humanely, and that removing the food and water source is often the best deterrent. They suggest the use of non-lethal traps, which are more expensive than other methods but can be found at most hardware stores or online shops which sell hardware supplies or pest remedies.

Electronic Pest Removal Tools

The University of Georgia warns that the use of lights or sound emitting devices is generally ineffective at getting rid of critters (source). While you may have some initial success, rodents will quickly become accustomed to the disturbances and will learn to ignore them much the same as person will become adjusted to recurring sounds or neighborhood lights that are on night after night.

Traditional Methods of Pest Control

In the long run, pesticides or spring-loaded traps will usually prove to be the most effective way to get rid of pests. If you have spotted spoor or nests, placing a couple of baited traps in close proximity can eradicate vermin quickly. Despite the popular myth, cheese is not always the best bait to use, and many experts suggest using peanut butter, balls of bread or even chocolate to lure in unwary rodents.

Since traditional traps are easy to find and cheap to buy, consider using several traps throughout the garage, especially near food, water, or nesting material. Check and re-bait your traps often until several days or even a week has gone by without trapping any vermin. Be sure to use gloves when removing rodents from traps and wash your hands thoroughly after doing so.

Another popular method of getting rid of mice is with bait stations such as the one by Tomcat. It uses an enclosed bait station which holds a small block of poison.

Because it’s enclosed except for the small rodent opening, it’s completely safe around children, cats, and dogs and works well both indoors and outdoors.

It works by attracting the rodent which then nibbles on the bait block. It doesn’t kill them immediately but after a day or two, it’s pretty much guaranteed you won’t have to worry about them anymore.

Most often they ingest the poison and go back to their burrows where they die. These bait stations are a good alternative for those that are squeamish and don’t want to deal with regular snap traps.

The biggest downside is that they may die someplace you can’t reach so then you have to worry about getting rid of that dead mouse smell.

Garages tend to be cluttered. For many of us, garages are the place to store the things we don’t want to bother fitting in our homes. Extra furniture, various lawn care equipment, gas cans, tools and anything to do with the cars that are kept in our garages.

Clear the Clutter

Garages tend to be cluttered. For many of us, garages are the place to store the things we don’t want to bother fitting in our homes. Extra furniture, various lawn care equipment, gas cans, tools and anything to do with the cars that are kept in our garages.

Of course, this unavoidably leads to clutter, which in turn, leads to mice. Why is this? The more clutter you have, the better hiding spots you’re providing for these furry little rodents.

Stacks and stacks of stuff, containers and piles of unsorted objects are all modes of protection for mice. They can scurry, dart and burrow in the piles of things you keep in your garage, and the best part is they’ll likely go unseen. Mice are nocturnal creatures, so the likelihood of you spotting these scurrying critters at night in between the cracks and crevices is slim.

Going through your garage and tossing and organizing its contents is a springtime, yearly chore anyway, and by doing this job, you’ll be saving yourself headaches in the future by avoiding any possibility of a mouse infestation.

Combined with bagging food sources and disposing of nesting material, cleaning your garage is an essential part of the process to keep your garage mouse-free.

Check Weather Stripping: Mice can sometimes chew right through the weather stripping at the bottom of a garage door. You may need to replace yours if it’s damaged.

Other Ways to Deter Mice

  • Keep your lawn trimmed and bushes and overhanging trees away from the house as much as possible.
  • Eliminate any food or water sources in the garage (garbage, dog food, bird seed, etc.), or seal them in rodent-proof containers.
  • Keep the garage clean. If you’ve had mice, clean your garage with an effective cleaning solution, and vacuum while wearing gloves and a dust mask. Mice can carry diseases, so it’s important to do a thorough cleaning once the mice are removed.
  • Keep your garage door in good shape.
  • If you can’t seem to get rid of your mouse problem, call a professional to deal with it for you.
