Rat Infestation Closes Duluth Elementary School for the Summer

June 13, 2018 11:31 PM

Duluth's Congdon Park Elementary has been closed for the summer due to an infestation of rats in the building's footing and foundation drainage system.

The Duluth School District announced the closure Wednesday, TV station WDIO reports, saying staff and a local pest control firm are working to clear the infestation.  


The district said pest control workers are currently trapping about five rats per day.

"We're working to remove them from the burrows created in the hillside and beneath the gym addition before they can get into the building itself," Dave Spooner, the district's facilities manager said in a news release.

"Having the building and grounds unoccupied will allow us the flexibility to take steps necessary to make that happen. We appreciate everyone's support as we work to keep our school grounds healthy."

Spooner said the district is using the least toxic method to remove the rats - pesticide bait boxes set outside the footing and foundation drainage system and near the burrow entrances in the hillside.  

The district is posting signs to alert people that the boxes are being used.

Spooner said the planned eradication methods are fully compliant with Minnesota Department of Health and Environmental Protection Agency guidelines.
