Finding a lizard in your garage or home might be frightening to many homeowners. Before you panic, remember that these lizards, typically geckos, are great at hunting insects and do not pose a threat to you or your family. To prevent them from getting inside, try lowering the thermostat and taking steps to reduce humidity indoors, in addition to sealing entry points (around doors and windows) and getting rid of their food source. You didn’t really want insects inside anyway, did you?
