Bat problems, HELP PLEASE

[Lisa Tomita]

My tenant called me to let me know she's caught three bats coming out of the chimney in the last few weeks. I called a handful of extermination specialists, seems like no one is willing to come to the property for less than $250. So, I gave in. I paid a guy $250 to look at my house.

He quoted me $3,000 to shoo out the bats, and seal off any potential entry points. The $3,000 doesn't include cleaning up guano. I feel like that's ridiculously expensive. Does anyone know a vendor who can do it for less? Maybe a handyman could do it? Any help would be very much appreciated.

I've also heard that if you put up a bat house somewhere near the home, it will help attract them away from the attic.
