Mice are drawn to decks for a variety of reasons. Decks provide an ideal environment for these rodents, offering them shelter, access to food, and a safe place to nest. When a deck is close to the ground, it creates a hidden, dark space perfect for these nocturnal creatures to hide and forage for food.

The presence of food sources, such as bird feeders, pet food, or table scraps, can also attract mice to your deck. Even the smallest amount of spilled food or garbage can entice these opportunistic critters, making your deck a prime location for them to build their nests.

It’s essential to take preventive measures to avoid potential damage caused by a mouse infestation, such as electrical wire chewing. In this article, we’ll explore 6 reasons why mice are attracted to decks, and give you attainable ways to repel them.

Key Takeaways:

  • Decks offer shelter, food access, and nesting materials for mice
  • Food sources like bird feeders, pet food, and garbage can attract mice to your deck
  • Prevent infestations by removing food sources, sealing entry points, and using natural deterrents

6 reasons Why Mice Are Attracted to Decks

Mice are opportunistic animals and will take advantage of any shelter that provides protection from predators and the weather. Decks serve as an ideal environment for mice for 6 main reasons. Let’s investigate them below:

1. Seeking Shelter & Warmth

Mice are drawn to your deck because it provides them with a perfect shelter. These little critters are always on the lookout for a cozy place to call home, and the gaps between the decking materials provide just that.

Shelter is an important component in the life of a wild mouse. An article from the Journal of Physiology and Behavior found that mice spend the least amount of time out in the open when compared to sheltered areas or partial-shelter areas. Decks provide the perfect sheltered area for these little intruders to feel safe and comfortable.

With their keen sense of smell, they can easily detect the dark and sheltered spaces underneath your deck, making it an ideal spot for nesting. To make things even more appealing, your deck is elevated from the cold ground, providing them with additional protection from predators and the elements.

2. Availability of Food Sources

Another reason why mice are attracted to your deck is the availability of food. As nocturnal creatures, mice venture out at night in search of food, and your deck might be a buffet in their eyes.

Householders tend to unknowingly provide food sources for mice in the form of crumbs, pet food, birdseed, and even discarded food from barbecues or picnics. As your deck can accumulate these nibbles, the mice cannot resist the temptation to come and feast.

This means that keeping your deck clean and free of potential food sources can make a big difference in deterring these furry visitors.

3. A Sense of Security

Mice are naturally drawn to areas that provide a sense of security. Your deck offers them plenty of hiding spots and cover from predators like birds and larger rodents. Additionally, they prefer dark places where they can go unnoticed, and the shadows cast by your deck fulfill their desires for a secure and concealed environment.

By nesting underneath your deck, mice can easily escape from danger and go about their business unnoticed. Maintaining a well-lit and clutter-free deck can help in making it less attractive for mice, ultimately keeping them at bay.

4. Staging Ground

Decks can act as a starting point for mice to explore the rest of your home, seeking more shelter, food, and warmth. Mice are known to be excellent climbers, and they can use decks as a way to get inside the home.

These small rodents are capable of squeezing through tiny openings, and they can easily climb up the sides of a deck to access the house. Once inside, mice can be difficult to get rid of, as they are known to reproduce quickly and can cause damage to the home by chewing on wires, insulation, and other materials.

5. Safe Place To Breed

Mice perceive decks around the home to be a safe place to breed because they provide a warm and sheltered environment that is protected from predators. Decks offer mice the perfect place to build their nests, as they are often located close to a source of food and water.

Mice are also attracted to decks because they provide easy access to the home, which allows them to move in and out of the house undetected. Once a mouse has established a nest under the deck, it will begin to breed and reproduce, creating a colony of mice that can quickly grow out of control.

6. Mice Love A New Playground

The final reason mice may be attracted to your deck is simply because they are curious creatures and love exploring new places. Mice are social creatures, and once someone has found a safe and cozy place, they’re likely to attract other mice.

Decks also have plenty of little ins and outs underneath that mice can crawl through, making it more or less a playground for these furry invaders.

Common Signs of Mice Infestations On The Deck

Visible Droppings

One of the most obvious signs of a mice infestation is the presence of mouse droppings. These rice-shaped and dark brown droppings are often found near their food sources or nesting areas.

Finding droppings on or around your deck is a strong indication that mice are attracted to it, and it’s time to take action!

Gnaw Marks

Mice have a constant need to gnaw on things to keep their teeth at the proper length. So, if you notice gnaw marks on the wood or other materials on your deck, this is another sign that mice have taken a liking to your space.

Keep an eye out for any small, distinctive teeth marks, as these are clear evidence of mouse activity!

Greasy Marks

Mice are creatures of habit, and they tend to follow the same paths when they’re moving from one place to another. As they scurry along these routes, their bodies often leave behind greasy marks or smudge lines on surfaces. If you spot any such marks on your deck, this could suggest you have an unwelcome visitor (or visitors) frequenting the area.

Sounds and Noises

Mice are nocturnal, which means they are most active at night. If you hear scurrying, scratching, or nibbling sounds coming from your deck after the sun goes down, there’s a good chance that mice are the culprits. While it’s not a foolproof sign of mice infestation, hearing these noises at night should definitely put you on high alert.

By looking out for these common signs of mice infestation, you can better understand why they are attracted to your deck and take measures to address the issue.

Consequences of Mice Infestations On The Deck

Property Damage

Mice are notorious for causing property damage when they decide to call your deck their home. These small but determined rodents are attracted to the safety of decks and often start nesting in it, gathering nesting materials such as shredded papers, fabric, and even insulation.

Not only do they make a mess, but they can also chew through electrical wiring, risking fire hazards. Moreover, they can weaken the structural integrity of your deck by gnawing on the wood.


Mice have a strong odor that can be unpleasant and difficult to get rid of, especially if they have established a large colony under the deck. The odors are due to the mice themselves, their urine, and their feces.

Odors are particularly strong near their nests, so keep your nose at the ready if you suspect a mouse infestation.

Home Invasions

Decks are typically attached to the home or somewhere close by so you can enjoy some much-needed relaxation time. Unfortunately, this means that decks could serve as a highway for mice to invade the home.

Mice can squeeze through holes slightly larger than 1/4 inch. If your deck is attached to the house and there is a minuscule gap, mice can exploit it and enter the home. Once inside, they’ll quickly establish a nesting area and start hitting up the kitchen for a midnight snack!

How To Keep Mice Off Your Deck

Sealing Entry Points

To prevent mice from entering your deck, start by sealing gaps and potential entry points. Mice can squeeze through tiny openings, so it’s important to inspect your deck thoroughly and seal any cracks or holes.

Some common materials used for sealing gaps include:

These materials are effective as they can withstand the sharp teeth of mice! Ensuring that your deck is fully secured is a critical step in keeping these little invaders at bay.

Maintaining Cleanliness

Mice are attracted to decks where they can find food and shelter. Keeping your deck clean and free of potential food sources is key. Here’s what you can do to ensure cleanliness:

  • Regularly sweep your deck to remove debris and any food crumbs
  • Dispose of trash in tightly sealed containers
  • Remove pet food dishes or bird feeders from your deck at night

By following these methods, you’ll create an unappealing environment for mice which drastically reduces their presence.

Using Mouse Traps

Mouse traps can be an effective way to catch mice and monitor the situation. There are various types of traps available, such as:

  • Snap traps – These eliminate the mouse.
  • Live-capture traps – These allow you to release the mouse far from your deck and are considered more humane. Try out Motel Mouse Humane Mouse Traps.

It’s essential to place the traps strategically around the deck, ideally close to their entry points or where they are most active. Check the traps regularly and dispose of the mice according to local guidelines.

Hiring Professional Pest Control

Sometimes, despite your best efforts, it may be necessary to seek help from a professional pest control service. They can provide expert advice and help implement advanced control measures customized for your specific situation.

Moreover, professionals have access to tools and techniques that can help manage the problem more effectively. To connect with a local pest control agency, use our nationwide pest control finder.

Use Natural Mouse Repellents To Keep Mice Off The Deck

Peppermint Oil - A natural mouse repellent

Peppermint Oil

Peppermint oil is an excellent choice for repelling mice from your deck. The strong scent of peppermint oil is known to be unpleasant for mice, helping to deter them from invading your outdoor space.

Create a peppermint oil spray by simply mixing a few drops of the essential oil, such as Brooklyn Botany Peppermint Essential Oil, with water. Spray the mixture around your deck, focusing on possible entry points where mice might be attracted. The refreshing smell can help keep these critters at bay while also providing a pleasant aroma for you and your guests.

Bait Stations with Natural Attractants

Instead of using harmful chemicals, try setting up bait stations using natural attractants around your deck. These bait stations can help lure mice away from your deck and capture them humanely in a live-catch trap.

Some attractive options include:

  • Peanut butter
  • Hazelnut spread
  • Seeds or nuts
  • Fresh fruits and vegetables

Placing these bait stations in strategic locations around your deck will allow you to catch and release mice without causing harm to them or other animals that might be attracted to your bait.

Essential Oils

Aside from peppermint oil, there are a few other essential oils that can be used to repel mice. Here are a few that will repel mice, and how you can use them around the deck to keep these critters at bay:

Essential OilHow to Use
EucalyptusMix eucalyptus oil with water in a spray bottle and spray the solution around the deck and in areas where mice are likely to enter.

By incorporating these natural mouse repellents into your routine, you can effectively deter mice from coming onto your deck. Additionally, maintaining a clean and tidy deck will discourage mice from finding shelter and food, further reducing the likelihood of an infestation.

Preventing Future Mice Infestations

Regular Inspection

Why do mice love your deck? To prevent future infestations, it’s crucial to inspect your deck regularly. Keep an eye out for any signs of mice activity, such as droppings, gnaw marks, or nesting materials. By spotting these early indicators, you can take appropriate action before the situation gets out of hand!

Removal of Potential Food Sources

Mice are naturally attracted to areas with food sources. To keep them away from your deck, make sure to:

  • Store food items in sealed containers
  • Clean up any food spillages immediately
  • Dispose of leftover food and waste in tight-lidded trash bins

With these strategies in place, mice will have a harder time finding anything to munch on around your deck!

Precautionary Measures

Taking preventive measures can go a long way in deterring mice from your deck. Here are some tips:

  1. Seal any gaps and holes: Mice can squeeze through small openings, so it’s essential to fill any holes or cracks they may use to access your deck area. Steel wool and caulk can be used for smaller gaps, while lath metal or cement can be used for larger ones.
  2. Eliminate nesting spots: Mice love nesting in piles of leaves, wood, and other debris. Make sure to clear such clutter from around your deck!
  3. Use natural deterrents: Some plants, such as mint or lavender, can help deter mice from your deck. Including these in your garden can be a lovely and natural way to discourage mice from getting too cozy on your deck.

By following these guidelines, you can ensure a mice-free deck and enjoy your outdoor living space without any uninvited guests!
