A colony of bats were found in a school. We stopped a colony of approximately 50 Mexican free-tailed bats from being exterminated in Tyler, TX. The bats were roosting in the foyer of a school. The school agreed to instead to perform a humane exclusion while also blocking the entryway into the school, allow the students to use a different entryway into the school until all of the bats have exited the building.
