How To Get Rid of Mice in Your Attic
DIY homeowners can handle their mouse problems quickly if they know what steps to take in the process. In this section, I’ll show you these steps, along with some methods exterminators use to kill mice and how to implement them right away.
1. Inspection
The first place to look for signs of a rodent infestation in the attic is within the fiberglass insulation. This soft material may seem a bit scratchy for humans, but mice love it because it provides warmth during the cold winter months.
It’s also worthwhile to look at other areas of the home as well. Having mice in the attic could mean they’re in different locations around your property. These include:
- Kitchen
- Pantries
- Pet areas
- Water heater
- Outdoor locations, including storage sheds and barns
2. Identification
Once you’ve confirmed that you have an infestation, it’s vital to know what rodent species you’re dealing with. For example, mouse droppings are much different in appearance than those of rats.
Rat and mouse nesting habits aren’t quite the same. By correctly identifying the rodent problem, you know what materials you need to conquer it.
3. Trapping
Trapping is the best way to perform a cleanout of mice in confined, indoor spaces. There are several types to choose from, such as:
Snap Traps
The best mouse traps to employ are snap traps. They’re pretty easy to set up, and they kill the mouse instantly and humanely.
Placing the trap can be a bit tricky the first time. Try following these steps to achieve the best results:
- Bait the trap with peanut butter, but only use a small amount. Also, try not to get any peanut oil on the trigger arm assembly, which could cause it to become slippery, making the trap difficult to set.
- Set the trap to a sensitive setting, making sure the mouse won’t be able to steal the bait.
- Carefully place the trap perpendicular to the wall. Be cautious when sliding it. The slightest vibrations can set the trap off.
- If the trap goes off prematurely, don’t worry. It happens to even the most experienced professionals. Try again following steps one through three. You’ll eventually get the hang of it.
Once you catch a mouse, it’s not worth it to save the trap. Instead, throw the whole thing away. Snap traps are relatively low-cost items, and it becomes too messy to separate dead mice from them.
Glue Board Traps
Glue traps are by far the easiest to use. You just fold them into a box and set them in place.
You can also lay a glue trap flat, which often works better. To make it even more effective, place a small dab of peanut butter in the middle to attract a mouse faster.
Live Traps
Live traps are available for mice. They allow you to release them after they’re trapped, which can be a more humane way of managing rodents.
The main drawback is that these traps are confined spaces that heat up quickly. That means the rodent can die from dehydration before you have a chance to release it, defeating the purpose of live trapping.
Shock Traps
Several electric shock traps are available for mice and rats. They’re typically box-shaped devices that kill the rodent instantly. You can use your favorite bait to attract them, and it’s a fairly simple matter to empty the trap.
Some electric traps work better than others, so it’s a good idea to do your homework. Also, read the product reviews carefully to make sure you are getting the best value.
4. Cleanup
After you’re confident you have removed the bulk of your mouse infestation, it’s time to clean the attic. Follow these steps to make things easier for you:
- Replace contaminated insulation. It’s best to spend a few extra dollars than to have rodent feces embedded in the insulation.
- Remove contaminated storage boxes and set them outside. Take inventory of everything in the box. Empty everything out and thoroughly wash stored items. Don’t forget to replace cardboard boxes with new ones.
- Wash all stored blankets and linens. This goes for jackets, shoes, and other clothing items as well.
- Vacuum leftover fecal material. Use a crevice tool to get into tight spaces. Afterward, replace the vacuum bag immediately.
- Clean all attic surfaces using a solution of bleach and water. To remove urine trails, you may need a blacklight to locate them.
It’s advisable to wear an OSHA-approved respirator when cleaning up after mice. This is because they transmit diseases through dried fecal material, and all you have to do to become infected is breathe the dust from it.
How to Keep Mice Out of Your Attic
The secret to rodent control around your home is preventing infestations from happening in the first place. Here’s how to do it.
1. Sanitation Measures
When limiting a rodent’s food source, working from the center and moving out is preferable. For example, starting with the attic, remove stored pet food or other material that may attract rodents.
Next, proceed to the kitchen. Store all food items in sealed containers. This goes for pet food as well.
Finally, move outdoors to the storage shed. Make sure birdseed, pet food, and other perishable items are kept in sealed containers. All outdoor trash cans should have securely fastened lids.
2. Seal Entry Points
Rodents often come in from the outside. It’s essential to seal entryways that provide easy access points to your attic. Apply hardware cloth or sheet metal to close holes in eaves and overhangs.
Use steel wool to plug pipe entry points. Rodents are constantly searching for water, so they’ll follow plumbing lines until they find it.
Finally, seal small holes with silicone caulking. This step will ensures that mice will have a hard time finding a way into your attic.
3. Repellents
Essential oil repellents can have a limited effect on deterring mice within localized areas such as attics and crawl spaces. You can also employ the use of ultrasonic pest repellers throughout your home for added protection.
However, repellents are merely one of many tools you can incorporate into your rodent control strategy. They should never be used as a stand-alone solution for getting rid of mice.
4. Defensive Baiting
Anticoagulant mouse baits shouldn’t be used indoors. Instead, place bait stations outdoors in these areas:
- Under porches or steps
- Crawl spaces
- Beneath junk piles
- Inside storage sheds
- Along the fence line of your property
The idea is to trap rodents inside living spaces to remove them. Then, lure them away from your house using mouse baits outdoors. This strategy ensures mice are attracted to areas outside your home instead of inside where you live.
5. Trim Trees and Shrubs Near Your Home
Keep trees and shrubs trimmed back from the exterior of your home. Mice can use overhanging branches as pathways to access your roof and find entry points into the attic space. Maintaining a cleared perimeter around your home’s exterior can help deter mice.
Trim any branches that hang over or touch your roof, as these provide easy access for mice. Ideally, you want to create a gap of at least six to eight feet between your home’s exterior walls and any landscaping to remove potential rodent highways.
In addition to pruning trees and shrubs, remove any dense vegetation or woodpiles that are located too close to your home’s foundation. These can provide mice with shelter and nesting areas near the house.
How To Identify Mice in Your Attic
All rodent control programs start with identification. Even if you’re not a pest expert, here’s how to tell the difference between rats and mice.
Mice Vs. Rats
The common house mouse is between four and five inches long. It has gray fur, black eyes, and exceedingly large ears. Also, its tail is about three-quarters the length of its body.
Juvenile roof rats are often mistaken for mice since their appearance is similar. The main difference is size. Roof rats can grow up to four times larger than mice.
Another distinction between rats and mice is their waste products. For example, mouse feces measure only four millimeters long and are tapered at both ends. In contrast, roof rat droppings are 13 millimeters long and are slightly curved.
Mice as Disease Vectors
Mice transmit a pulmonary infection known as hantavirus. They’re also capable of contaminating food, resulting in salmonella poisoning. While it’s unlikely that mice pass on fleas to pets, it’s still possible.
There are several ways to tell if you have a mouse infestation. The following represent the most obvious examples.
Nesting Areas
Mice have a need to escape cold temperatures. Unfortunately, your attic may be the perfect spot they’re seeking.
Mouse nests can be located anywhere within your home. In the attics, they’re most often in boxes of clothing or within fiberglass insulation. Nesting materials include cotton clothing, shredded paper, or even wood chips.
Rodent Waste
Mouse droppings are probably the most obvious sign you have an infestation. Urine trails are another. Still, they may not be easy to spot without a blacklight.
Dead mice are also an indicator of a possible infestation. Look for fresh droppings in the area to confirm it.
Damage
Another sign that you may have a problem is the presence of chewed electrical wiring. In addition, there may be oily rub marks along the drywall left by mice.
Noise
Mice are noisy little critters. Hearing scurrying and squeaking sounds in the middle of the night are clues you may have a mouse infestation.
Mice transmit a pulmonary infection known as hantavirus.
They’re also capable of contaminating food, resulting in salmonella poisoning. While it’s unlikely that mice pass on fleas to pets, it’s still possible.

Is it possible to get rid of mice in the attic?
Yes, it is absolutely possible to get rid of mice in your attic. With the proper inspection, identification of entry points, trapping, baiting, exclusion techniques, and follow-up, you can remove mice from living in your attic space.
What do mice eat in the attic?
Mice will eat almost anything they can find in an attic, including insulation, cardboard boxes, paper products, stored food items, pet food, and more. They only need small amounts of food and can survive on crumbs. Clearing out clutter and potential food sources is important.
What is the best way to get rid of mice in your attic?
In my experience, the best way is an integrated approach using multiple methods. This includes sealing entry points, setting traps (snap traps are most effective), using rodenticide baits placed in strategic locations, removing food sources, and filling larger holes to prevent re-entry. Consistency is key.
What will an exterminator do to get rid of mice?
Professional exterminators have access to stronger rodenticides and trapping methods. They will conduct a thorough inspection, identify active areas, set up a strategic baiting/trapping plan, and return to remove mice and replace baits as needed until the infestation is removed. They may also use exclusion techniques like sealing entry points.
How can I humanely remove mice from my attic?
Using humane live traps that catch mice without killing them is one option. However, this requires much checking traps and properly releasing mice far away. Many find that kill traps like snap traps are more effective. Sealing entry points is the most humane way to keep mice out in the first place.
Final Thoughts on How To Get Rid of Mice in Your Attic
Once you discover a mouse problem in your home, it becomes a race against the clock to end them. This is because they reproduce quickly. For example, one female can produce over 50 offspring in less than 12 months.
