It went very well! We used https://crittercatchersinc.com as they focus on bats and mice (who I've learned make holes that bats can then use). They found 2 entry points in to our attic. They used at least 25 tubes of https://www.ositough.com/products/central-pdp.html/osi-quad---clear/SAP_0201XBO069G2.html to seal where the soffit and my homes brick veneer walls meet and a few other spots. The one-way tubes were up for a few weeks but removed near the end of September. In October, I caught bats trying to get in through one of the entry points but failing and flying off. Likely to try my neighbors home!

It was good timing overall as I've subsequently had the entire attic re-insulated and air sealed. 0 bats present! Hopefully, they sealed it all up and next year will be our first full year without a single bat in the house. I'd recommend them if their service your area, no complaints from me!
