Some gardeners live in harmony with lizards and enjoy the free pest control these insect-eaters provide. The creatures can become a nuisance, however, when they start eating garden plants or find their way out of the garden and into your home. You can curb lizard problems by harassing the lizards, disturbing breeding sites and avoiding plants that attract them. When all else fails, you may need to capture your garden lizard and release him somewhere else, but only if it is legal to do so in your area.
Sweep up and dispose of fallen leaves and other dead plant debris in the garden. Debris provides cover and nesting areas for lizards. If you compost old plant debris, place the compost pile away from your home, outbuildings and other areas where lizards are undesirable. Move lumber piles, stacks of bricks, boxes and other things that trap moisture and provide hiding places for lizards. Place these items away from your home, or dismantle them.
Place outdoor potted plants on top of elevated plant stands so lizards aren't attracted to the moist environment beneath the pots. Remove fallen leaves from inside the pots so lizards can't hide under them.
Empty and store all items that can hold standing water. Bowls, empty pots and buckets are breeding grounds for mosquitoes and other insects, which attract lizards. If you must leave empty bowls, pots and buckets outdoors, turn them upside down so they won't collect water.
Harass lizards whenever you see them. Spray them with a garden hose or chase them away whenever you can. This will make them associate your yard with unpleasant things so they will stay away. Hang old compact discs from trees and prized plants. The movement of the reflected light will help chase lizards off when you're not there to do it.
When you find a lizard nest, remove the eggs from it and seal them in a plastic bag for disposal. Interfering with lizard nests reduces nuisance lizard populations and discourages lizards from building future nests in the area.
Seal all openings that are more than 1/4 inch wide in your home and other buildings by filling them with caulk or stuffing steel wool into them. Sealing keeps the lizards from gaining entrance. Common entrance points are around window and door openings, water pipes and electrical outlets.
In areas where it's legal to trap and release lizards, you can trap and remove any unwanted visitors. Trap lizards using fruit-baited live traps or nets. If you're fast, you can also simply drop a cardboard box over the lizard and then slide another piece of cardboard underneath it to contain the animal. Transport trapped lizards inside live traps or in cardboard boxes so they can't bite you. Baby lizards can often be caught by hand and carried to a release area. If trapping and releasing lizards is illegal in your area, call in a wildlife control specialist.
