FOUNTAIN INN, S.C. (AP) - The bats are back at Fountain Inn Elementary School.
And Greenville County school officials are again working to seal the building to make sure the bats who leave at night to hunt cannot get back inside.
The school dealt with hundreds of bats in February, closing the entire building for a day.
On Monday, officials moved kindergarten students out of two classrooms after officials found bats in the building over the weekend.
School district spokesman Oby Lyles says maintenance workers and pest experts sealed cracks in the building and installed traps over roof drains that allow the bats to exit, but not re-enter.
Lyles says the ventilation system in a kindergarten bathroom had a crack in a pipe that allowed the bats to enter the building.
