How it kills: Sick bats won't think twice about entering your home, because like other rabid animals, they display decreased wariness around people. One's probably already turned your attic into a makeshift cave and is waiting patiently to bring pain with its infectious saliva-laden bite when you take it by surprise. Things get tricky—and deadly—if you don't seek immediate testing and treatment.
How to get it before it gets you: Avoid contact with wild bats, dead or alive. Bat-proof your home by repairing exterior holes and slits—think matchbook-size—that a bat can feasibly wiggle through.
