13 Ways to Keep Lizards Out of Your Garage and Claim Your Space Back

Lizards might seem like harmless creatures, but finding them scuttling across your garage floor can be unsettling. Not only is it unexpected, but their presence can also indicate an insect problem you might not be aware of. Lizards are excellent insect hunters, and their presence suggests a readily available food source in your garage.

More importantly, a lizard infestation can be a nuisance. Their droppings can be unpleasant to clean up, and they might damage stored items while searching for hiding spots.  Luckily, there are several ways to keep these unwelcome guests out of your garage and reclaim your space.

1. Seal Up Entry Points: Block Those Tiny Ninja Entrances

Lizards are known for their agility and ability to squeeze through surprisingly small openings. To prevent them from entering your garage, the first step is to identify and seal any potential entry points.

  • Inspect your garage door: Pay close attention to the weather seal around the bottom of the door. Over time, these seals can wear down and create small gaps. Replace worn-out weather stripping with a new one to ensure a tight fit.
  • Check windows and doors: Look for any cracks or gaps around windows and door frames. Even a tiny opening can be enough for a determined lizard. Use caulk to seal small cracks, and consider adding weather stripping for a more comprehensive solution.
  • Don’t forget the vents!: Vents are another potential entry point for lizards. Cover them with fine mesh screen to allow air circulation while keeping critters out.

For larger openings or for those who want a more professional solution, consider hiring a weatherization service. These professionals can identify and seal any potential gaps in your garage’s exterior, ensuring a lizard-proof environment.

2. Eliminate the Buffet: Starve Out the Lizard Visitors

As mentioned before, lizards are drawn to garages because they offer a readily available food source – insects. By eliminating the insect population in your garage, you make it a much less attractive destination for these reptiles. Here are some tips:

  • Store food in sealed containers: This will prevent insects from being attracted to leftover food scraps or pet food.
  • Keep trash cans clean and sealed: A overflowing trash can is a haven for insects, and by extension, lizards. Ensure your trash cans have tight-fitting lids and empty them regularly.
  • Consider natural insect repellents: Certain scents, like peppermint oil or cedarwood oil, are known to deter insects. You can place cotton balls soaked in these oils around the perimeter of your garage for added protection.

3. Make Your Garage a No-Go Zone for Lizards with Natural Repellents

There are several natural repellents that you can use to make your garage unappealing to lizards. However, it’s important to be aware of the limitations and safety precautions involved:

  • Spicy deterrents: A spray made with hot pepper flakes or cayenne pepper mixed with water can be an effective lizard repellent. However, be mindful when using this method, especially if you have pets or allergies.
  • Mothballs: While commonly used as a deterrent, mothballs contain naphthalene, a chemical harmful to humans and pets. It’s best to avoid this method altogether.
  • Ultrasonic repellents: These devices emit high-frequency sounds that are supposed to repel lizards. However, their effectiveness is debatable, and some people find the noise irritating.

4. Declutter and Clean: Remove Hiding Spots and Lizard Hotels

Lizards love clutter. A cluttered garage provides them with numerous hiding spots, making it difficult to locate and remove them. Here’s how to make your garage less inviting:

  • Organize your belongings: Store items in sealed containers or on shelves to minimize clutter on the floor.
  • Sweep and clean regularly: Regular cleaning removes potential food sources for insects and eliminates hiding spots for lizards.
  • Remove potential nesting materials: Debris piles, leaf litter, or even old rags can provide nesting material for lizards. Get rid of any such materials lying around your garage.

5. Employ a Friendly Predator (Catch and Release, Responsibly)

This method might sound unconventional, but it can be effective in certain situations. Introducing a harmless snake species, known to prey on lizards, into your garage can act as a natural deterrent. However, this approach requires significant caution:

  • Local regulations: Always check your local regulations before introducing any snake species, even a harmless one. Releasing non-native species can disrupt the local ecosystem.
  • Humane practices: If you decide to go this route, ensure you use humane methods to capture and release the snake after it has done its job.

6. Light Up the Night: Discourage Nocturnal Visitors

Lizards, especially geckos, are often most active at night. Making your garage unappealing during these hours can be a great deterrent.

  • Install bright motion-sensor lights: Equipping your garage with motion-sensor lights will not only deter lizards but also improve security. The sudden burst of light will startle them and discourage them from entering.
  • Leave a dim light on overnight: While not as effective as motion-sensor lights, keeping a low-wattage light on overnight can disrupt a lizard’s nighttime routine and make your garage less inviting.

7. Invest in a Fake Owl: A Bluff with a Feathered Friend

Predators are natural deterrents for lizards. Placing a strategically positioned realistic-looking fake owl in your garage can create the illusion of a threat.

  • Placement matters: Position the owl near the entrance or high on a shelf where it’s clearly visible.
  • Rotate its position: To maintain effectiveness, occasionally rotate the position of the owl to prevent lizards from becoming accustomed to it.

8. Utilize Natural Barriers: Plants with a Purpose

While some plants might attract insects, there are certain species known to repel lizards due to their strong scent or texture. Consider planting these deterrents around the perimeter of your garage:

  • Lemongrass: The citrusy scent of lemongrass is known to be unpleasant to lizards.
  • Marigolds: These vibrant flowers not only add a pop of color but also have a strong odor that deters many insects, indirectly discouraging lizards.
  • Lavender: While known for its calming effect on humans, the scent of lavender is disliked by lizards. Planting lavender near the garage entrance can be a fragrant deterrent.

9.  Encourage Competition: Attract Beneficial Insects

Creating a habitat for beneficial insects, like ladybugs or praying mantises, can be a natural way to control the insect population in your garage. This, in turn, discourages lizards that rely on insects for food.

  • Provide shelter: Place small wooden boxes or ladybird houses in your garage to provide a haven for these beneficial insects.
  • Plant a pollinator garden: Planting a small pollinator garden near your garage can attract these beneficial insects and create a natural ecosystem that controls the overall insect population.

10. Maintain a Moisture-Free Environment

Lizards often seek out damp areas to regulate their body temperature. Keeping your garage dry and well-ventilated can make it a less hospitable environment for them.

  • Address leaks: Identify and repair any leaks that might be introducing moisture into your garage.
  • Improve ventilation: Ensure proper ventilation in your garage by opening windows or installing exhaust fans. This will help remove excess moisture and create a drier environment.

11. Sonic Deterrents: A Controversial Choice

Ultrasonic repellents emitting high-frequency sounds are a popular option for deterring lizards. However, their effectiveness is a subject of debate.

  • Limited research: While some studies suggest ultrasonic repellents might have some effect on pest control, the research is inconclusive.
  • Potential for annoyance: The high-frequency sounds emitted by these devices can be irritating to humans and pets.

If you decide to try ultrasonic repellents, be aware of the limitations and choose a model with adjustable frequencies to minimize disruption for yourself and your furry companions.

12.  Ammonia-Based Sprays: A Temporary Solution

Ammonia has a strong odor that some find unpleasant, including lizards. Ammonia-based sprays can be used as a temporary deterrent.

  • Short-lived effect: The effectiveness of ammonia-based sprays fades quickly as the ammonia evaporates. Frequent reapplication is necessary.
  • Safety concerns: Ammonia can be harmful if inhaled or if it comes into contact with skin or eyes. Always wear gloves and ensure proper ventilation when using ammonia-based products.

Due to the limitations and safety concerns, ammonia-based sprays are best used as a last resort and should be handled with caution.

13.  Professional Help: When DIY Methods Fall Short

If you’ve tried various methods and are still struggling with a persistent lizard infestation, it’s time to call in the professionals.

  • Expertise and resources: Professional pest control companies have the expertise and resources to identify the source of the infestation and implement targeted solutions.
  • Long-term solutions: Professionals can not only eliminate existing lizards but also identify and seal entry points to prevent future infestations.

While professional help might come at a cost, it can be a worthwhile investment for a severe infestation or if DIY methods haven’t yielded the desired results.

Conclusion: A Multi-Pronged Approach is Key

While each of these methods can be effective on its own, the best approach to keeping lizards out of your garage is to use a combination of them. Here’s why:

  • Layered defense: By addressing multiple aspects that attract lizards (insects, hiding spots), you create a more comprehensive defense system.
  • Long-term solution: Sealing entry points and eliminating insect populations provide a long-term solution, preventing future infestations.
  • Adaptability: Lizards can be persistent, so using a variety of methods makes it harder for them to adapt and find a way back in.

Remember, if you’re dealing with a severe infestation, it might be best to consult a professional pest control service. They have the expertise and resources to handle the problem quickly and effectively.
