Finding a gecko in the living room is startling, but a yard overrun with lizards means it is time to rethink your landscaping strategy. Learning how to keep lizards out of your yard starts with understanding what attracts them in the first place. These reptiles are not malicious, but they can become a nuisance when they slip through door cracks or leave droppings on your patio furniture.
Lizards are cold-blooded, which means they need warm spots to bask and cool, damp places to hide. If your yard offers an all-you-can-eat buffet of insects, you have basically hung out a welcome sign. The good news is that you can make your property less inviting without harming the animals. You just need to change the environment.
Why Are Lizards In Your Yard?
Before you start making changes, you need to see your yard from a lizard’s point of view. They are not looking for trouble. They are looking for three things: food, water, and shelter. If you remove these elements, they will move on to a neighbor’s property.
Most lizards eat insects like crickets, ants, roaches, and spiders. If you have a lot of plant debris, standing water, or outdoor lights that attract bugs, you will have lizards. They also love rock piles, wood stacks, and thick ground cover because these spots offer protection from birds and other predators.
Signs Of A Lizard Infestation
You might not see the lizards themselves right away. They are fast and shy. Instead, look for their droppings, which are small, dark, and have a white tip. You might also find shed skin near window frames or under planters.
Another sign is a sudden drop in the spider population around your porch. While that sounds like a good thing, it means lizards are actively hunting there. If you see them darting under the grill or into a bush when you walk outside, you have a healthy population living on your property.
How To Keep Lizards Out Of Your Yard
This is the core of your strategy. You are going to make your yard less comfortable for them. The process involves a mix of cleaning, landscaping changes, and natural repellents. It does not require poison or traps, which are often ineffective and cruel.
Start with a full inspection. Walk around your yard and look for the specific hiding spots mentioned below. Take notes on where you see the most activity. This will tell you where to focus your efforts first.
Remove Their Food Source
You cannot eliminate every insect, but you can reduce the population. Turn off outdoor lights when you are not using them. Lights attract moths and beetles, which attract lizards. If you need security lighting, use yellow bulbs or sodium vapor lamps. These are less attractive to insects.
- Keep your gutters clean to avoid standing water where mosquitoes breed.
- Remove pet food bowls from the yard after your pet finishes eating.
- Make sure your trash cans have tight-fitting lids to keep flies away.
- Treat your lawn for grubs and ants if the population gets out of control.
You should also consider a bug zapper. While the sound is annoying, it will reduce the number of flying insects available for lizards to eat. Just place it far away from your seating area.
Eliminate Hiding Spots
Lizards like to feel secure. They will hide under anything that is flat, dark, and close to the ground. This includes boards, bricks, and pieces of plywood. If you have a pile of lumber for a project, store it off the ground and away from the house.
- Move firewood at least 18 inches off the ground and store it away from exterior walls.
- Replace loose pavers or stones that create gaps.
- Fill in cracks in your concrete driveway or patio with caulk.
- Trim bushes and shrubs so the lower branches are off the ground.
- Avoid using thick mulch right next to the foundation.
Rock gardens are beautiful, but they are also lizard condos. If you have a rock wall or decorative stones, consider replacing them with larger river rocks that have fewer gaps. Or, you can simply accept that those areas will house lizards and focus on keeping them away from the house itself.
Change Your Landscaping
Ground cover plants like ivy or pachysandra are perfect for lizards. They hold moisture and offer constant shade. If you have these plants right up against your foundation, you are providing a highway for lizards to reach your doors and windows.
Create a barrier of gravel or pebbles that is about two feet wide around the perimeter of your home. This dry, open space is uncomfortable for lizards to cross. They prefer to stay in moist, vegetated areas. This simple strip of stones can cut down on the number of lizards that get close to the house.
You should also keep your grass mowed short. Tall grass holds humidity and hides insects. Short grass gives lizards no cover, making them vulnerable to predators. This encourages them to stay in the thicker brush further away from your living spaces.
Use Natural Repellents
There are several scents that lizards dislike. You can use these to create a chemical-free barrier around your patio or garden. These are not guaranteed to work forever, but they are a good deterrent when used consistently.
- Eggshells: Crush them and scatter them around planters. The sharp edges are unpleasant for lizards to walk on.
- Coffee grounds: Mix them with tobacco powder and place the mixture in small piles. The smell is strong and masks the scent of insects.
- Garlic and onion: Place cloves or slices near entry points. The sulfur compounds irritate their senses.
- Pepper spray: Mix water with a few drops of hot sauce and spray the perimeter of your patio.
You can also buy commercial lizard repellent sprays. Look for ones that use natural ingredients like peppermint oil or citronella. These are safe for pets and children, but they need to be reapplied after it rains.
Set Up Physical Barriers
If you have a serious lizard problem, you might need to block them physically. This is especially important if they are getting inside your home. Install weather stripping on the bottom of your doors. Check the seals around your windows and garage door.
You can also use a fine mesh or netting to cover vents and gaps in the eaves. Lizards can squeeze through surprisingly small openings. A gap of a half-inch is enough for a small gecko to get through. Seal any holes you find with steel wool or expanding foam.
For your garden beds, consider installing a low fence made of plastic or metal sheeting. Bury the bottom edge a few inches into the soil. This will stop ground-dwelling lizards from moving into the area. It is a lot of work, but it is a permanent solution.
Plants That Deter Lizards
Some plants have properties that lizards find offensive. Adding these to your garden can help keep them away. This is a passive method that looks nice and requires little maintenance.
- Lemongrass: The citrus oil in this plant is a natural insect repellent, which means less food for lizards.
- Mint: The strong smell is overwhelming to reptiles. Plant it in pots to prevent it from taking over your yard.
- Eucalyptus: The scent is pleasant to humans but repulsive to lizards.
- Marigolds: These flowers have a distinct odor that deters many pests, including lizards.
- Lavender: The essential oils in lavender are a known deterrent for various reptiles.
Plant these near your doorways, windows, and patio edges. You can also crush the leaves and rub them on surfaces to release the oils. This is a great way to use what you already have in your garden.
Dealing With Water Sources
Lizards need water to survive. They will drink from bird baths, pet bowls, and even puddles. If you have a pond or a fountain, you are providing a water source. While you do not want to dry up your garden, you can make it less accessible.
Place bird baths in the middle of the yard, away from walls and fences. This gives lizards less cover when they approach the water. If you have a drip irrigation system, make sure it is not leaking and creating muddy patches. Fix any outdoor faucets that drip.
If you have a pool, keep the surrounding deck dry. Lizards will come to the edge to drink the chlorinated water. While it is not good for them, they will still do it. A quick sweep of the deck to remove standing water will help.
What About Natural Predators?
Encouraging natural predators is a long-term solution. Cats are the most obvious choice. A cat that hunts will keep the lizard population down. However, not all cats are hunters, and some people do not want outdoor cats.
You can also attract birds of prey like hawks and owls. Installing an owl box in a tall tree might encourage them to nest nearby. These birds will eat lizards, snakes, and rodents. This is a natural form of pest control that requires no effort from you once the box is up.
Keep in mind that some lizards are beneficial. They eat ticks, which can carry Lyme disease. If you live in a wooded area, a few lizards might be helping you more than you know. The goal is to keep them out of your living spaces, not to eliminate them from the ecosystem entirely.
Maintaining A Lizard-Free Yard
Once you have removed the lizards, you need to keep them away. This requires consistency. You cannot clean the yard once and expect the problem to be solved forever. Insects will return, and so will the lizards.
Make a habit of inspecting your yard every few weeks. Look for new piles of debris, overgrown bushes, or standing water. Address these issues immediately. The longer you wait, the more likely a lizard will find the new habitat and move in.
Reapply your natural repellents after heavy rain or every two weeks during the summer. The scents fade quickly. If you use eggshells, replace them when they start to decompose. A little bit of routine maintenance goes a long way.
Frequently Asked Questions
Does vinegar keep lizards away?
Yes, the strong smell of vinegar is a deterrent. Mix equal parts water and white vinegar in a spray bottle. Spray it around the perimeter of your patio and near doorways. Be careful not to spray it on plants, as it can kill them.
Will mothballs get rid of lizards?
Mothballs are toxic and not recommended. They are dangerous for children and pets. While the smell might deter lizards, the health risks are not worth it. Stick to natural repellents like garlic or pepper spray instead.
Do lizards bite humans?
Most yard lizards are harmless and will run away before you get close. If you corner one, it might bite in self-defense. The bite is usually not painful and does not break the skin. Wash the area with soap and water if it does.
Why do lizards keep coming back?
They keep coming back because the conditions are still favorable. You likely still have insects, water, or hiding spots. Review the steps above and see which one you missed. The most common reason is that the food source has not been addressed.
Are lizards dangerous to my garden?
No, lizards are actually beneficial to gardens. They eat many pests that damage plants, such as slugs and beetles. They do not eat plants or roots. The only issue is the mess they leave behind on patios and walkways.
Keeping your yard lizard-free is a process of elimination. You are removing the things they need to survive. It takes a few days to see results, but the changes are permanent if you stay on top of them. Start with the food source, then move to the shelter, and finish with the repellents. You will notice a difference within a week.
Dont get frustrated if you still see one or two lizards after you have done all of this. They might just be passing through. The goal is to make your yard a place they do not want to stay. With these steps, you can reclaim your patio and enjoy your outdoor space without the constant skittering and surprise visitors.
Remember to check your window screens and door sweeps one last time. That is how they get inside. If you stop them at the perimeter, you wont have to worry about finding them in your living room. A little effort outside saves you a lot of stress inside.
You can do this. Just take it one step at a time. Clean up the clutter, change the landscaping, and use the natural scents they hate. Your yard will be less inviting to lizards, and more enjoyable for you and your family.
