Why Mice Are Attracted to Composts

Compost bins and compost piles are a safe haven for mice. They provide mice with everything they need to survive, making it an attractive hangout spot in your yard. Mice aren’t the only visitors to compost piles, but they can certainly be the most annoying!

An article from the Journal of EcoHealth found that visitation rates by wildlife to compost piles and bins were 8 times higher than in urban natural areas.


Mice are primarily attracted to your compost pile due to the abundance of food they can find there. Scraps like fruit, vegetables, and grains provide a never-ending buffet for these uninvited guests!

Ensuring that all food waste is properly buried within the compost can help make it less appealing to them.

Water Availability

Mice need water to survive, just like any other creature. A moist compost pile provides an ideal environment for rodents to hydrate themselves. To minimize the water content in your compost, consider mixing in more dry materials such as leaves, twigs, or straw.

Shelter And Warmth

Compost piles give off heat during the decomposition process, making them a cozy and warm place for mice to nest. Moreover, the presence of organic matter offers them an excellent spot to build nests and raise their young.

To prevent mice from treating your compost like a vacation home, turn it regularly to disrupt their nesting process and increase the speed of decomposition.

Bonus Benefit: The faster your compost pile decomposes, the more quickly you can use it to enhance your garden’s soil!


Rodents are often prey, so they appreciate a protected environment that offers them a sense of safety. Compost piles can function as a fortress for mice, shielding them from predators and harsh weather conditions.

To counter this, try placing a 1/4-inch hardware cloth around the base of the compost bin, preventing mice from entering.


Mice are naturally attracted to human settlements, primarily because we unintentionally provide them with the resources they need—food, water, and shelter—in one convenient package. Your compost pile is no exception.

To deter these persistent furballs, consider implementing humane methods like scattering some strong-smelling natural substances like peppermint oil near the compost area.

A welcoming compost environment – rich with food, water, and shelter – will undoubtedly catch the attention of mice. A few simple adjustments to your compost management can help deter these unwanted visitors while still maintaining a healthy, eco-friendly approach to waste disposal.

How to Identify a Mice Infestation in Compost


Mice are skilled burrowers, and you might spot tiny holes or tunnels in your compost pile. These tunnels often lead to their nesting areas. Keep an eye out for these little entrances, as they can be a sure sign that mice have made themselves at home.


Mice droppings are another telltale sign of an infestation. Look for small, dark pellets scattered around your compost pile, as these are most likely left by unwanted rodents. Remember, if you see droppings, there’s a good chance there are more than a few mice nearby!

Nesting Materials

Mice like to build cozy nests using materials they find nearby. In a compost pile, you might spot shredded plant matter, leaves, and even scraps of paper or cloth that they’ve collected. These nests can often be found tucked away in burrows or other hidden places within the compost.


Mice have a distinctive odor – a musty, somewhat unpleasant smell. Trust your nose when inspecting your compost pile for signs of a mice infestation. If you detect a consistent, unusual odor around your compost, rodents might be the source!


In addition to their main entry points, mice will often create a network of small tunnels throughout the compost pile to move around with ease. Examine the pile’s surface for signs of tunneling. Keep in mind, mice are great at staying hidden, so these tunnels might be hard to spot at first glance.

By understanding these signs of a mice infestation in your compost, you can take steps to humanely repel them and maintain a healthy, rodent-free composting environment.

Preventive Measures Against Mice Infestations In Compost

Compost Bins Can Attract Mice

Use Cats To Repel Mice

A furry friend can be the perfect solution for deterring mice, as their natural hunting instincts will help keep your compost free from rodents. Cats will not only keep mice at bay but also provide companionship, making them a useful and adorable inclusion in your home life!

Secure Compost Lids Keep Mice Out

It’s always critical to use a sturdy, tight-fitting lid on your compost bin. Mice may be small, but they’re also persistent, so a durable and secure lid is essential for keeping them out. By having a lid that’s easy to secure, you can keep your compost safe from unwanted visitors.

Turn Compost Regularly To Remove Mice Nests

Regularly turning your compost helps maintain an appropriate balance of materials in the pile, which can discourage mice from moving in. Additionally, frequent turning makes it more difficult for mice to establish nests within the compost, making it less appealing for them to stay.

Keep A Balanced Compost To Prevent Mice

Maintaining a balanced compost is crucial in preventing mice infestations. By blending equal amounts of brown (carbon-rich) materials, such as straw and leaves, with green (nitrogen-rich) materials, like fruit and vegetable scraps, you create an ideal environment for breaking down organic matter.

Create A Physical Barrier Around Your Compost

Another effective method to keep mice away from your compost is by installing physical barriers, such as mesh wire or hardware cloth, around the bin. This acts as a protective shield and makes it more difficult for rodents to gain entry.

AggFencer 36inch x 10ft Hardware Cloth 1/8inch is the perfect size for your compost bin, as mice can’t squeeze through the small 1/8-inch holes. Consider burying the barrier a few inches underground to prevent mice from burrowing underneath.

By following these preventive measures, you can ensure that your compost remains a safe and productive space for breaking down organic materials without any unwanted mouse-related disruptions.

What Not To Compost To Keep Mice Away

While composting is a fantastic way to create nutrient-rich soil for your plants, there are certain items you should avoid adding to your compost bin. These items can not only attract pesky rodents like mice, but can also cause unpleasant odors and disrupt the composting process.

Meat & Dairy

Items such as meats, bones, cheeses, and dairy products are a big no-no when it comes to composting. The delicious aroma of these items will attract mice to your compost heap, turning your eco-friendly efforts into an all-you-can-eat buffet for rodents!

Fats And Oils

Adding oils and fats to your compost pile can slow down the decomposition process. These materials form a barrier that prevents oxygen from reaching the microbes that break down organic matter.

Not only do fats and oils slow down the composting process, they’re also highly attractive to mice.

5 Things To Do If Mice Are In Your Compost

Mice in your compost pile can be a headache, but thankfully, there are several humane and eco-friendly ways to address this problem!

Let’s discuss some handy, natural, and humane pest control methods to help you deal with the mice in your compost.

1. Traps

By using a live trap, you can catch the mouse and release it far away from your home and compost pile. These traps are designed to capture the mice without harming them. Motel Mouse Humane Mouse Traps are some of the best in the business! They’re easy to set up and are cruelty-free.

When baiting traps, use enticing things like peanut butter, chocolate, smelly cheese, or bacon.

2. Mouse Repellents

There are several natural mouse repellents available on the market, such as essential oils or even homemade solutions like peppermint-soaked cotton balls. These natural deterrents work by masking the scent of food, predators, and other mice, making the area less habitable for mice.

Here are a few natural mouse repellents you can use around your compost bin:

Natural Mouse RepellentHow to Use to Repel Mice from Compost Bin
Peppermint OilSoak cotton balls in peppermint oil and place them around the compost bin. Or, add 10-15 drops of essential oil to a spray bottle full of water and spray around the compost bin.
Cayenne PepperSprinkle cayenne pepper around the compost bin. Alternatively, combine 1/8-tbsp cayenne pepper with 1 cup of water and place in a spray bottle to use around the compost.
GarlicCrush garlic cloves and spread them around the compost bin. Garlic must be crushed or chopped to release the scent that repels mice!

It’s important to note that while these natural mouse repellents can be effective in repelling mice from the compost bin, they may not work for all situations. It’s also important to use these repellents safely and according to their instructions.

3. Predators

Don’t forget about predators! Cats and dogs can make a significant difference in keeping mice in check. Allow your pets to roam near the compost bin – their scent can help scare off any mice looking to make a cozy home in your compost pile.

Cats and dogs aren’t the only predators mice are afraid of. The scent of foxes and coyotes can make mice scurry in the opposite direction. Consider using predator urine like PredatorPee Original Fox Urine.

Owls are another major predator of mice. Consider setting up an owl box in the yard near the compost bin to encourage these birds of prey to set up camp and keep the mice population in check. Just be aware that it may take some time for owls to realize there is a nesting box there.

4. Professional Pest Control

Seeking professional help is also an option. Opt for pest control companies that have experience in dealing with mice in compost piles and can offer humane solutions. Be sure to compare different service providers and choose one that aligns with your values and objectives.

5. Proper Compost Maitenance

We’ve mentioned it before, and it’s worth mentioning again. Turning your compost pile regularly can make it less attractive to mice by disrupting their environment. It makes it hard for them to build nests when they’re being turned upside down regularly!

In addition to turning the compost pile, be sure to maintain a proper balance of brown and green substances to speed up the breakdown process. This means less food scraps for mice.

Remember, you are in control of your compost pile, and you have the power to effectively and humanely deal with the mice situation. By trying these various methods, you’ll be on your way to a mouse-free compost pile and a healthier garden environment.

Plant Deterrents To Keep Mice Out Of Compost


Mice are not fans of strong-smelling plants, so incorporating them into your compost area might save you from a potential “mice-tastrophe.” Lavender plants, for example, emit a scent that makes mice steer clear, and they’re a beautiful addition to your garden as well! So, if you want to avoid Mickey and Minnie from dining at your compost party, planting lavender nearby is a fantastic idea!


Another popular scent that mice dislike is mint. Luckily, you can grow both peppermint and mint in your garden. Not only will these plants help keep mice at bay, but they also have some benefits for you and your garden patch. They’ll freshen up space, and you can even use the leaves in teas or homemade meals.

By implementing these natural deterrents and preventative measures, you can enjoy the benefits of composting without worries about mice making themselves at home in your garden. Remember, it’s your responsibility to manage your compost heap wisely – and the furry nuisances will find a different place to forage and dwell.

6 Steps To Rehabilitate Your Compost After a Mouse Infestation

Have you been to your compost pile recently and spotted uninvited guests? Sometimes mice find their way into our compost. Here’s how you can regain control of your pile.

1. Assessing the situation
First, make sure the infestation is indeed caused by mice. Look for droppings, small tunnels, and other indicators of their presence. If it’s confirmed you are indeed dealing with mice, proceed to the next step.

2. Protect yourself
Don’t forget to put on gloves. Handling the compost directly, especially when dealing with animal feces, can be hazardous. Precautions are always a good idea!

3. Remove food scraps
Mice are attracted to the smell of food waste in your compost pile. To minimize their stay, be sure to remove the visible table and kitchen scraps like vegetables, fruits, and any other yummy leftovers.

4. Ensure compost balance
Maintaining a balance between carbon and nitrogen is key. Adding more brown materials such as leaves, straw, and other yard waste helps keep the pile less attractive to pests!

5. Stir it up!
Turning (mixing) the compost pile regularly can help to break down food scraps faster and make it less enticing for the mice. It also helps improve aeration and control the moisture levels.

6. Seal and secure
It’s fundamental to ensure that your compost pile is secure – after all, you don’t want the mice feeling at home. Here are a few ideas:

  • Place a wire mesh or screen beneath the compost pile to create a barrier to entry.
  • Use a bokashi bucket to ferment your food scraps before adding them to the compost. This process makes the scraps less attractive to mice.
  • Keep a tight lid on compost bins to prevent access to the food within.

Don’t worry – be scrappy!
Remember, while dealing with an infestation can be frustrating, calmly following the steps above will have them rolling their tiny suitcases in no time.

That’s A Wrap!

Mice in your compost pile can be a tricky problem. However, understanding why they’re attracted to such an environment and implementing humane solutions can help keep your compost rodent-free.

Here’s a recap of the 5 things to do if mice are in your compost pile:

  1. Use live traps to catch and remove mice
  2. Use natural mouse repellents like peppermint, cayenne, and garlic around the compost pile
  3. Enlist the help of predators to keep mice populations in check
  4. Hire a pest control specialist
  5. Perform regular compost maintenance

It’s not a mouse party without food, and compost piles provide an abundance of dining options for these little critters. Make sure to bury plant food waste deep in the pile, and cover it with several inches of soil, finished compost, or at least a foot of dry leaves to deter mice.

Another way to avoid unwanted guests is to maintain a balance of materials in your compost pile. Proper balance ensures that the pile does not become too damp or too acidic, which could attract mice and other pests.

Lastly, although not specifically a compost solution, practicing good yard hygiene is also crucial. Clearing away piles of leaves or debris and trimming down tall vegetation can make your outdoor space less inviting for mice and other rodents looking for a sheltered home.

By considering these five factors and taking proactive steps to implement humane deterrents and proper compost maintenance, you can create an environment that is both beneficial for your garden and unwelcoming to mice.
