If you're lucky enough to have one move in. I have a bat house in hopes of natural mosquito control. It's been a few years and there's no sign of use.
This is absolutely nuts. Also how would he know that he wasn't bitten if it brushed up against him.
I paid $400 to have it captured and tested (which involves killing it). It was negative. It could have bit me in my sleep, and I was glad to not get that series of shots (at the time it was those ones that go into your gut) or wait it out and wonder if I would die a year later.
