Students in a few dorms found some unwelcome visitors this month.

Students in Bobb Hall and Foster-Walker Complex found mice in their rooms about three weeks ago.

The mice were caught and removed fairly quickly but not before upsetting several residents, students in the affected dorms said.

Weinberg sophomore Stacy Kramer said she got worried when some of her neighbors in Bobb spotted mice, so she and her roommate put some traps down just in case.

“A few days later my roommate saw a tail in one of the traps,” Kramer said. “That’s when we realized we also had mice.”

She said housing services responded quickly by setting more traps and getting rid of the mice but said she hopes the rodents don’t come back.

“Everyone in my hall was freaking out for about a week,” Kramer said. “I hope the mice are gone and the problem is taken care of.”

The mice likely came in from outside, said Mark D’Arienzo, associate director of university housing.

“It was not an infestation,” he said. “The mice came in because someone left their door open.”

D’Arienzo said Bobb Hall was the most affected dorm. Three rooms in the same hallway of Bobb had mice.

“Traps were laid, four mice were caught, and there has not been a problem in the past 12 days,” he said. “We are confident that the problem is resolved.”

Some students weren’t bothered by the furry residents. Wenny Ng, a McCormick junior who lives in Foster-Walker Complex, said she chased the mouse she found in her room. But when it disappeared in her room, she decided she could live with it.

“I put some peanut butter across the room,” Ng said. “The next morning there were little footprints in it, so I just did that for a few days. I didn’t really mind.”

She said she didn’t mind the mouse, but when she told her friends about it they got upset and called housing services.

“My friends were more bothered by the whole thing than I was,” Ng said. Someone came with traps and the mouse was gone within the week, she said.

“Mine was a little guy, he was actually kind of cute,” she said. “I named him Richard.”
