The most effective way to get rid of lizards on your patio is to remove what attracts them: insects, water, and hiding spots. Lizards hang around patios because these spaces offer warmth, shelter, and a steady food supply. A combination of habitat changes and natural repellents will push them to find a better spot.
Why Lizards Love Your Patio
Patios check every box for a lizard looking for a place to settle. Warm concrete and stone absorb heat during the day, giving lizards the surface temperature they need to regulate their body. Potted plants, stacked furniture, storage bins, and decorative rocks create hiding spots. Outdoor lights attract moths, flies, and beetles at night, which means a reliable buffet. Standing water in plant saucers, birdbaths, or drainage trays rounds out the appeal.
Understanding this is useful because it tells you exactly what levers to pull. You don’t need to chase lizards away one by one. You need to make the patio a less attractive place to be.
Cut Off Their Food Supply
Lizards go where the bugs are. If your patio has a noticeable insect population, that’s the single biggest reason lizards stick around. Reducing insects makes the space far less interesting to them.
Start with outdoor lighting. Standard white bulbs attract flying insects. Switching to yellow-tinted or sodium vapor bulbs dramatically reduces the number of moths and beetles that cluster around your patio at night. If you use string lights or decorative fixtures, the same rule applies.
Keep the patio swept and free of food debris, especially after grilling or eating outside. Crumbs and spills attract ants and roaches, which attract lizards. Empty pet food bowls rather than leaving them out overnight. For a more aggressive approach, apply a perimeter insecticide around the base of your patio, foundation walls, and door thresholds. Longer-lasting liquid formulations work well when sprayed in a two to six foot band along the ground and two to three feet up any adjacent walls. With fewer insects around, lizards lose their main reason to stay.
Remove Shelter and Hiding Spots
Lizards are prey animals. They need quick access to cover, and a cluttered patio gives them plenty of it. Trim back any vegetation that touches or overhangs the patio, especially dense shrubs and ground cover plants. Pull potted plants a few inches away from walls so lizards can’t squeeze behind them. Stack firewood, lumber, or storage items away from the patio rather than against it.
Rock borders, decorative stone piles, and landscape fabric edges are favorite hiding spots. If lizards are a persistent problem, consider replacing loose rock borders with cleaner edging that doesn’t offer gaps. The goal is to make the patio feel exposed. A lizard with nowhere to hide won’t linger.
Seal Entry Points
If your patio connects to the house through a sliding door, garage entrance, or screen enclosure, sealing gaps keeps lizards from becoming an indoor problem too. A gap as small as a quarter inch (roughly the diameter of a pencil) is large enough for a small lizard to squeeze through.
Install door sweeps at the base of exterior doors and check the bottom corners, where gaps tend to be largest. Line the bottom track of sliding glass doors with half to three-quarter inch foam weatherstripping. Seal utility openings where pipes and wires pass through walls using silicone caulk, expandable foam, or copper mesh. Caulk cracks around windows, fascia boards, and where the patio structure meets the house. Acrylic latex caulk is easy to work with and paintable, while silicone caulk offers more flexibility for joints that shift with temperature.
Natural Repellents That Work
Several household ingredients create scents and sensations that lizards avoid. These won’t eliminate lizards entirely, but they help reinforce the message that your patio isn’t welcoming.
- Pepper spray: Mix a few tablespoons of cayenne pepper or hot sauce with warm water in a spray bottle. Spray it along patio edges, around furniture legs, and near any gaps where lizards enter. The capsaicin irritates lizards on contact. Reapply after rain.
- Garlic and onion: Lizards find the strong smell intolerable. Place raw garlic cloves or onion slices in corners of the patio, or blend them with water and spray the mixture along baseboards and walls.
- Essential oils: Citronella, lemongrass, peppermint, and eucalyptus oils all repel lizards. Mix 10 to 15 drops with water in a spray bottle and apply around the patio perimeter. Citronella and lemongrass have the added benefit of repelling mosquitoes, which removes one of lizards’ favorite food sources.
One popular remedy you can skip: eggshells. The idea that eggshells scare lizards away has no scientific support. Lizards may actually eat them.
What Not to Do
Salt is sometimes suggested as a lizard deterrent, but it works by dehydrating the animal, causing organ damage and a slow death. It’s unnecessarily cruel for a problem that has simpler solutions. Glue traps catch lizards but also trap beneficial insects, small birds, and other wildlife. They leave the lizard to die of stress and dehydration over hours or days.
Poison is both impractical and risky. There are no lizard-specific poisons available to consumers, and rodenticides or insecticides used off-label can harm pets, children, and other wildlife that share your patio.
Why You Might Want to Keep Them
Before going all-in on removal, it’s worth knowing that most common patio lizards (anoles, geckos, fence lizards) are highly effective pest controllers. A single lizard can eat dozens of insects per day, including mosquitoes, ants, roaches, spiders, and garden pests. If your main complaint is that there are one or two lizards sunning themselves on the railing, you may actually benefit from their presence.
The health concern worth knowing about is Salmonella. All reptiles, including common garden lizards, can carry Salmonella bacteria in their digestive tract. The bacteria spreads through contact with reptile droppings. This is mainly a concern if small children play on the patio and put their hands in their mouths, or if lizard droppings accumulate on surfaces where you prepare or eat food. Regular cleaning of patio surfaces and hand washing after contact with areas where lizards are active reduces this risk to nearly zero.
For most people, the best approach is a middle ground: reduce the lizard population to a manageable level through habitat changes and repellents rather than trying to eliminate every last one. A patio with fewer bugs and less clutter will naturally support fewer lizards, and the ones that remain will be earning their keep.
