i saw them all summer long OUTSIDE, but never inside my brothers hold killed 3 of them. And I aversion lizards and im afraid of them. My brother says they are safe and are like spiders they newly get within the house..but I i'm not afraid of spiders and omg if a lizard gets within the bed with me, i may only pass out. Also I don't enjoy any other problems ie roaches..could it be something under the house..i enjoy a mobile home.
