I imagine some people find Bats intriguing, and sure when I am watching a nature show they can be. Having them live on or in my house is a whole other story. Bats can be found nesting behind window shutters or inside attics. They like to attach themselves to the walls of porches, patios, near outside lighting, waiting to make a meal of flying insects; If you detect oval shaped droppings stuck to stucco walls in these outside areas, they were left by bats.
