The Martin Luther King Jr. Student Union building, a popular student study area and home to dozens of student organizations, was partially closed after bed bugs were discovered Tuesday on the second floor.

According to campus spokesperson Adam Ratliff, the pests were found in a seating cushion on the second floor and likely originated from a visitor. With thousands of students set to arrive next week ahead of fall classes that start Wednesday, some areas in the building will remain closed until Sunday, he said.

“At this time, measures are being taken to detect if bedbugs are present elsewhere and, as a precaution, potentially impacted areas of the Student Union have been closed to the public,” Ratliff said in an email.

The furniture where the bugs were found has since been removed, according to Ratliff. ASUC staff and campus pest services will treat the area with chemical and steam applications to prevent the possibility of an infestation.

The Amazon campus store, located on the building’s second floor, reopened Friday at 9 a.m. for order pickups and returns, and will remain open until 9 p.m., according to its Facebook page.
