How to Keep Mice Out of Stored Cars, A Comprehensive Guide

How to keep mice out of stored cars – Protecting your stored car from pesky mice is crucial to prevent damage and maintain its value. This comprehensive guide explores effective strategies, from preventive measures to professional solutions, empowering you to keep mice at bay and ensure your car remains pristine.

Mice can wreak havoc on stored cars, causing damage to upholstery, wiring, and even the engine. Understanding their habits and implementing preventive measures are essential to keep them away.

Preventive Measures

To keep mice out of stored cars, preventive measures are crucial. These include sealing entry points, utilizing ultrasonic pest repellents, and strategically placing mothballs.

When considering selling a car, one option is to consign it to a dealer. Consignment fees vary, so it’s important to research the cost of consignment before making a decision. Alternatively, you can opt to sell the car yourself, which involves preparing it for sale and handling the transaction.

This option can be more time-consuming but potentially more cost-effective, especially if you’re able to negotiate a favorable price.

Sealing Entry Points

Cracks, holes, and other openings provide mice with easy access to vehicles. Seal these entry points using steel wool or caulk. Steel wool is effective for filling small gaps, while caulk is suitable for larger openings. Ensure thorough sealing to prevent mice from sneaking through.

Ultrasonic Pest Repellents

Ultrasonic pest repellents emit high-frequency sound waves that are inaudible to humans but deter mice and other pests. These devices are available in various forms, including plug-in units and portable models. While their effectiveness can vary, ultrasonic repellents can be a useful addition to a comprehensive pest control strategy.


Mothballs contain naphthalene, a chemical with a strong odor that repels mice. Place mothballs strategically inside the car, avoiding direct contact with fabrics or surfaces. The pungent odor creates an unpleasant environment for mice, discouraging them from entering. However, it’s important to use mothballs with caution, as excessive exposure can be harmful to humans and pets.

Natural Deterrents

Mice have a keen sense of smell, and certain scents can be highly effective in deterring them. Natural deterrents, such as peppermint oil, cinnamon, and cloves, emit strong odors that mice find unpleasant.

To use these scents effectively, you can diffuse essential oils into the air or place sachets filled with dried herbs or spices in areas where mice are likely to enter. You can also sprinkle cinnamon or clove powder around potential entry points.

Potential Drawbacks

  • Some natural deterrents may be irritating to humans or pets.
  • The effectiveness of natural deterrents can vary depending on the individual mouse and the severity of the infestation.
  • Natural deterrents may need to be reapplied regularly to maintain their effectiveness.

Traps and Removal: How To Keep Mice Out Of Stored Cars

Trapping and removing mice is an effective way to keep them out of stored cars. There are various types of traps available, each with its advantages and disadvantages.

If you choose to sell the car yourself, you may want to consider “bagging” it. Bagging involves wrapping the car in a protective covering to prevent damage during transport. The cost of bagging varies depending on the size and type of vehicle, as well as the materials used.

Snap Traps

  • Pros: Inexpensive, easy to set, and highly effective in killing mice quickly.
  • Cons: Can be dangerous for children or pets, and mice may learn to avoid them.

Live Traps

  • Pros: Humane, as they capture mice without harming them, allowing for relocation.
  • Cons: Can be more expensive than snap traps and require regular monitoring to prevent the mice from escaping.

Electronic Traps, How to keep mice out of stored cars

  • Pros: Advanced and highly effective, using electrical shocks to kill mice instantly.
  • Cons: Can be expensive and require batteries or electricity to operate.

Once mice are captured, it’s important to release them safely far from the car. Wear gloves and release them in a wooded area or field at least 1 mile away from your home to prevent them from returning.

Professional Solutions

How to Keep Mice Out of Stored Cars, A Comprehensive Guide

If home remedies fail to deter mice, consider seeking professional pest control services. Pest control professionals possess expertise and specialized tools to effectively eliminate mice infestations.

Professionals typically employ two main methods: baiting and exclusion.


Baiting involves placing traps or bait stations containing rodenticides in strategic locations where mice are likely to frequent. These rodenticides are formulated to attract and eliminate mice, effectively reducing their population.


Exclusion focuses on sealing entry points and gaps that allow mice to access stored cars. Professionals identify these entry points through thorough inspections and seal them using materials such as caulk, steel wool, or expanding foam. This prevents mice from entering the storage area in the first place.

Hiring a pest control professional offers several advantages, including:

  • Expertise and experience in handling mice infestations
  • Access to specialized equipment and rodenticides
  • Customized treatment plans tailored to the specific needs of the property
  • Ongoing monitoring and follow-up to ensure long-term effectiveness

However, professional pest control services come at a cost. The expense varies depending on the severity of the infestation, the size of the property, and the duration of the treatment plan. It is important to compare quotes from multiple pest control companies to find the best value for money.

End of Discussion

Keeping mice out of stored cars requires a multifaceted approach. By implementing preventive measures, utilizing natural deterrents, employing traps, and considering professional solutions, you can effectively protect your vehicle from these unwelcome guests. Remember, vigilance and regular maintenance are key to maintaining a mouse-free environment for your stored car.
