Vinegar & water 50/50. Spray them and the roost area. I know they eat mosquitos but we had 40 or 50 take over the gable louvers on our attached garage and made a mess. Bat chit everywhere. Tolerated it a couple years and cleaned up after them. Then decided God don’t put me here to clean up after bats. Get them all together in daytime and spray them with a pump sprayer and the vinegar water. They may persist for a couple nights but will eventually find another motel.
The only way to prevent reinfestation is to physically block entry. That’s what I did after getting them evicted.

"And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him."
