Garlic is just one product that will keep lizards away from a house. Residents should place the garlic cloves around the doors or other areas where the lizards enter the home.
Coffee grounds, onion slices and pepper spray also keep lizards away from the home. The most effective way to use these items to repel the lizards is to place them near the the lizards' nest. Mothballs and eggshells are also safe remedies for getting rid of lizards, but both of these just need to be changed out every few weeks. For heavy lizard infestations, a professional exterminator may be required.
