WICHITA, Kan. -

The Wichita school district is working to get rid of a colony of bats from one of its middle schools.

A classroom at Curtis Middle School is under quarantine after more than a dozen bats have been removed from the school so far.

Several teachers have seen them perched in corners of their classrooms or tucked behind posters on the walls.

The director of Environmental Services for Wichita schools says the bats are a "nuisance" but haven't caused any major problems.
