MEMPHIS, Tenn. — A high school in Tennessee that's been struggling with a pest infestation recently re-opened following treatment only to close again.

Shelby County Schools Superintendent Dorsey Hopson tells 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 re-opened Tuesday only to close when signs of pests and decay were found Wednesday. The district says it already has spent about $70,000 trying to eliminate the pests.

Hopson says students will need to make up for lost class time. He says night classes, Saturday classes and online classes are being considered and will be presented to the school board Tuesday. He said officials are looking at options to move students to another location until Kirby reopens.
