MEMPHIS, Tenn. — A high school in Tennessee that has been struggling with a pest infestation recently reopened following treatment — only to close again.

Shelby County Schools Superintendent Dorsey Hopson told WREG-TV that Kirby High School will be closed for another six to eight weeks so pests can be eradicated.

The school closed last week for treatment following complaints of rat, roach and snake sightings. It reopened Tuesday, only to close when signs of pests and decay were found Wednesday. The district said it already has spent about $70,000 trying to eliminate the pests.

Hopson said students will need to make up for lost class time. She said night classes, Saturday classes and online classes are being considered and will be presented to the school board Tuesday.
