Keep Mice Out of Your Stored Car, A Comprehensive Guide

How to keep mice out of a car in storage? This question plagues car owners who value their vehicles and want to protect them from these pesky rodents. Mice can wreak havoc on cars, chewing on wires, nesting in upholstery, and leaving behind droppings that can damage the interior.

Fortunately, there are effective measures you can take to keep mice at bay and ensure your car remains safe during storage.

In this comprehensive guide, we will delve into the strategies and techniques that will help you seal entry points, deter mice with repellents, remove food sources, use traps and baits effectively, keep your car clean, consider the storage environment, and monitor your car regularly to prevent mouse infestations.

Identify Entry Points

Mice can enter cars through a variety of openings, including:

  • Cracks in the bodywork or windows
  • Holes in the floor or trunk
  • Openings around the exhaust pipe or tailpipe
  • Gaps around the hood or trunk lid
  • Open windows or doors

It is important to inspect your car carefully for any potential entry points. Pay particular attention to areas where there are gaps or openings. You can use a flashlight to help you see into dark areas.

Seal Entry Points, How to keep mice out of a car in storage

Once you have identified any potential entry points, you should seal them up. You can use a variety of materials to do this, such as caulk, expanding foam, or steel wool. Be sure to seal up any gaps or openings completely.

Seal Entry Points

Once you’ve identified potential entry points, it’s time to seal them off to prevent mice from getting into your car. There are several methods you can use, depending on the size and location of the holes or gaps.


Caulk is a flexible sealant that can be used to fill small holes and cracks. It’s available in a variety of colors to match your car’s paint, and it’s easy to apply with a caulk gun. Simply clean the area around the hole or crack, apply the caulk, and smooth it out with your finger or a putty knife.

Expanding Foam

Expanding foam is a polyurethane-based sealant that expands to fill larger holes and gaps. It’s available in a can with a nozzle, and it’s easy to apply. Simply insert the nozzle into the hole or gap, and squeeze the trigger.

The foam will expand to fill the space, and it will harden within a few hours.

Steel Wool

Steel wool can be used to fill larger holes or gaps that can’t be sealed with caulk or expanding foam. Simply stuff the steel wool into the hole or gap, and it will act as a barrier to keep mice out.

Steel wool is also a good option for sealing holes or gaps around pipes or wires.

Deter Mice with Repellents: How To Keep Mice Out Of A Car In Storage

Mice have a keen sense of smell, which makes repellents an effective way to keep them away from your car. Both natural and commercial repellents can be used to create an unpleasant environment for mice, deterring them from entering or nesting in your vehicle.

Natural repellents include:

  • Mothballs:The strong scent of mothballs is known to repel mice. Place a few mothballs in a mesh bag or container and hang it under the hood or in the trunk of your car.
  • Peppermint oil:Mice dislike the smell of peppermint. Soak cotton balls in peppermint oil and place them around potential entry points, such as under the seats or in the glove compartment.
  • Ultrasonic devices:These devices emit high-pitched sounds that are inaudible to humans but can deter mice. Place ultrasonic devices in areas where mice are likely to enter, such as near the wheels or under the hood.

Commercial repellents are also available, such as:

  • Rodent repellents:These products contain ingredients that mice find unpleasant, such as capsaicin or peppermint oil.
  • Electronic pest repellents:These devices emit electromagnetic waves that are designed to deter mice.

When using repellents, it is important to follow the instructions carefully and to avoid using excessive amounts. Some repellents can be harmful to humans or pets if not used properly.

Remove Food Sources

Preventing mice from entering a stored car requires eliminating potential food sources that might attract them. Mice are opportunistic feeders, and even small amounts of food can be enough to entice them. By removing these temptations, you can significantly reduce the likelihood of a mouse infestation.

To effectively remove food sources from your car, follow these tips:

Clean Up Crumbs and Debris

  • Thoroughly vacuum the car’s interior, paying close attention to seats, carpets, and crevices where crumbs or debris may accumulate.
  • Wipe down surfaces with a damp cloth to remove any remaining food particles.
  • Inspect and clean cup holders, door pockets, and other storage compartments for any leftover food or drinks.

Store Food Properly

  • Avoid leaving food or drinks inside the car, even for short periods.
  • If you must transport food, store it in airtight containers or bags to prevent odors from attracting mice.
  • Keep pet food in sealed containers and store them outside the car if possible.

Use Traps and Baits

Traps and baits are effective methods for capturing mice that have already entered your car. Choose traps that are specifically designed for mice, such as snap traps, live traps, or electronic traps. Bait the traps with food that mice find appealing, such as peanut butter, cheese, or bacon.

Setting Traps

Place the traps in areas where mice are likely to travel, such as along walls, near food sources, or in dark corners. Set the traps according to the manufacturer’s instructions. Be sure to wear gloves when handling traps to avoid leaving your scent on them.

Using Baits

Use baits that are attractive to mice, such as peanut butter, cheese, or bacon. Apply the bait sparingly to the trigger of the trap. Avoid using too much bait, as this can make the trap less effective.

Keep the Car Clean

Mice are attracted to food, so keeping your car clean and free of crumbs and spills will help deter them. A clean car will also make it easier to spot any signs of mice, such as droppings or nests.

Cleaning Checklist

  • Vacuum the interior of your car, including the trunk.
  • Wipe down all surfaces with a damp cloth.
  • Empty all trash cans and remove any food items.
  • Store food in airtight containers.
  • Wash the exterior of your car, paying attention to the wheel wells and undercarriage.

Consider Storage Environment

The location where you store your car can significantly impact the likelihood of a mouse infestation. Mice are attracted to warm, dark, and sheltered spaces, so choosing a storage space that is well-ventilated, dry, and free from clutter is crucial.

Here are some tips for choosing a secure and dry storage space:

Storage Location

  • Avoid storing your car in damp or humid areas:Mice are attracted to moisture, so avoid storing your car in basements, garages, or other areas that are prone to dampness.
  • Choose a well-ventilated space:Good ventilation helps to keep the air dry and discourages mice from nesting in your car.
  • Keep the storage area clean and free of clutter:Clutter provides hiding places for mice, so keep the storage area clean and free of debris.

Monitor and Maintain

Regular inspections are crucial for keeping mice out of a stored car. Signs of mice infestation include droppings, urine stains, gnaw marks, and a musty odor. Inspect the car thoroughly every few weeks, paying attention to areas where mice are likely to nest, such as under seats, in the trunk, and in the engine compartment.

If you notice any signs of mice, take immediate action to prevent further infestation.

Preventative Measures

In addition to regular inspections, there are several preventative measures you can take to keep mice away from your car:

  • Keep the car clean and free of food debris.
  • Store food items in airtight containers.
  • Seal any cracks or holes in the car’s exterior.
  • Use mothballs or other natural repellents to deter mice.
  • Park the car in a well-lit area.

Last Recap

By following these steps, you can effectively keep mice out of your stored car and maintain its pristine condition. Remember, prevention is key, so stay vigilant and take proactive measures to protect your vehicle from these unwanted guests.

Regular inspections are crucial. Check your car monthly for droppings, chewed wires, or nesting materials. Early detection allows you to take prompt action and prevent significant damage.

What is the best type of trap to use for mice in a car?

Snap traps are effective and easy to use. Place them near potential entry points or areas where you’ve noticed mouse activity. Bait them with peanut butter or cheese for best results.
