The most effective way to get rid of lizards on your porch is to remove what’s drawing them there in the first place: insects, light, and shelter. Lizards aren’t visiting your porch randomly. They’re finding a reliable food source, warm surfaces for basking, and plenty of hiding spots. Address those three things and most lizards will move on within days.
Before you start, it’s worth knowing that porch lizards are genuinely useful. Green anoles eat flies, mosquitoes, termites, and cockroaches. Five-lined skinks, common across the southeastern U.S., feed on termites, grasshoppers, spiders, and roaches. If you can tolerate them, they’re providing free pest control. But if you’d rather not share your porch, here’s how to make it less appealing.
Switch Your Porch Lights
This is the single highest-impact change you can make, and it costs about three dollars. Standard white or blue-toned LED bulbs attract huge numbers of flying insects at night, and those insects are the main reason lizards camp out near your porch. Mediterranean house geckos, one of the most common porch lizards in the southern U.S., are nocturnal and come out specifically to feed on insects swarming around lights.
Swap your white porch bulbs for warm amber or yellow LED bulbs rated at 2700K or lower. A warm amber bulb attracts roughly 80 to 90 percent fewer insects than a cool white one, because insects can barely detect the longer yellow wavelengths. That one swap dramatically cuts the lizard buffet. If you want to go further:
- Use motion-sensor lights instead of leaving porch lights on all night. Insects only gather when the light is on, so less on-time means fewer bugs.
- Shield your fixtures so light shines downward rather than outward. This reduces how far the light attracts insects from.
- Close blinds at night. Interior light spilling through windows also draws insects to your porch.
- Turn off unnecessary lights entirely. The simplest option is often the most effective.
Remove Hiding Spots and Shelter
Lizards need places to hide from predators, cool down, and sometimes lay eggs. Your porch likely offers several options they find irresistible. Foundation cracks, stacked firewood, dense potted plants, mulch beds, and clutter all mimic the rocky crevices and leaf litter lizards seek in the wild. Five-lined skinks in particular look for dark, damp spots around porches for shelter and nesting.
Walk around your porch and look at it from a lizard’s perspective. Move firewood stacks away from the house. Pull potted plants a few inches from walls so there’s no hidden gap behind them. Clear out any accumulated junk, old shoes, boxes, or stacked materials that create dark spaces underneath. Seal visible cracks in your foundation or porch framing with caulk. If you have a thick mulch bed right against the porch, consider replacing it with gravel or pulling it back several inches from the structure.
Reduce Insects Around the Porch
Beyond lighting changes, there are other ways to cut down on the insects that lizards are hunting. Standing water in plant saucers, clogged gutters, or decorative containers breeds mosquitoes. Compost bins and uncovered trash near the porch attract flies. Overgrown vegetation right against the house harbors all kinds of small insects and spiders.
Trim bushes and plants so they don’t touch or overhang the porch. Empty standing water regularly. Keep compost and garbage bins as far from the porch as practical. If you have a garden bed adjacent to the porch, you’re essentially creating a habitat corridor for both bugs and the lizards that eat them. The more distance you put between plant-heavy areas and your porch, the fewer lizards will make the trip.
Natural Repellent Sprays and Deterrents
Several strong-smelling substances can make your porch less inviting to lizards, though none are guaranteed to work as a standalone solution. They work best as a supplement to the environmental changes above.
Peppermint oil and clove oil are the most commonly recommended options. Mix a few drops of either into a spray bottle of water and apply it around porch railings, corners, window frames, and any crevices where you’ve seen lizards. Lizards dislike strong scents, and these oils are potent enough to discourage them from lingering. Reapply every few days or after rain.
Crushed garlic cloves placed near entry points work on a similar principle. The sulfur compounds in garlic produce a sharp smell that lizards avoid. Cayenne pepper or chili powder mixed with vinegar and lemon juice can also be sprayed on surfaces. The capsaicin irritates lizards’ skin, eyes, and nose. Be cautious with pepper-based sprays if you have pets or small children who might touch treated surfaces and then rub their eyes.
Eggshells are a folk remedy you’ll see recommended frequently. The idea is that lizards mistake them for bird eggs and associate the area with predators. Some people report success placing cracked eggshells near windows and porch corners, though this is more anecdotal than proven. They’re free and harmless, so there’s little downside to trying them. Replace them every few days before they start to smell.
Citronella, whether as candles, oil, or planted lemongrass, also repels lizards with its strong scent. If you already use citronella for mosquitoes on your porch, it’s doing double duty.
Catching and Relocating Lizards
If you have a few persistent lizards that won’t take the hint, you can catch and move them. The simplest method for most porch lizards is the cup-and-cardboard technique: slowly approach the lizard, place a clear cup or container over it, then slide a piece of stiff cardboard underneath. Carry the whole thing to a wooded area or garden well away from your house and release it.
For lizards that are too fast to corner, sticky glue traps designed for mice can work. Place them along walls or near spots where you regularly see lizards. Once a lizard is caught, you can free it by gently applying vegetable oil to dissolve the adhesive. Researchers who’ve used this method on wild lizards report the animals don’t appear to suffer lasting harm from either the glue or the oil. Check glue traps frequently, ideally every few hours, so lizards aren’t stuck for extended periods.
Another approach for persistent lizards is to bait a small live trap with a cricket or mealworm near their favorite hiding spot. Place the trap near a crack or gap where you’ve seen a lizard retreat, and leave it for a few hours. Lizards will often investigate the bait and enter the trap on their own. This takes patience but avoids the stress of chasing them.
What Doesn’t Work Well
Ultrasonic pest repellers are widely sold for lizards, but there’s little reliable evidence they work outdoors where sound dissipates quickly. Commercial lizard repellent sprays exist, but their effectiveness varies widely and most rely on the same essential oils you can mix yourself for a fraction of the cost.
Cats are sometimes suggested as a lizard deterrent, and while cats will hunt lizards, relying on a pet for porch pest control introduces its own set of problems and isn’t a targeted solution.
Poison is both unnecessary and counterproductive. Lizards aren’t harmful, and poisoning them can endanger pets, children, and the birds and snakes that naturally keep lizard populations in check.
Keeping Lizards Away Long-Term
The lizards on your porch are a symptom of an insect-friendly environment. The most durable fix is making your porch a place where insects don’t congregate. Once you’ve switched to amber lighting, sealed hiding spots, and reduced the surrounding insect habitat, new lizards have very little reason to show up. Reapply scent-based repellents every week or two during warm months as an extra layer of deterrence, especially if you live in the South where species like Mediterranean house geckos and green anoles are abundant year-round.
If lizards keep appearing despite all of these steps, you likely have a significant insect population nearby that’s worth addressing on its own. Tackling the bug problem, whether it’s a moisture issue attracting roaches, standing water breeding mosquitoes, or dense landscaping harboring spiders, solves the lizard problem at its root.
