Despite an exhaustive effort by the Stanford Housing Service to exterminate the bedbugs that plagued Alondra in the fall, the unwelcome pests have resurfaced in the Florence Moore Hall dorm.

On Friday, all the rooms in Alondra were examined for bedbugs, and an infestation was discovered in a third-floor room. The discovery of the blood-feeding insects was the first on the third floor, after bedbugs attacked more than half a dozen second-floor rooms in December.

“They did a check a couple of days ago, and they found just one bug in the room,” said Garner Kropp, a freshman resident of the infested room. “Now, they are probably going to take out all the carpeting, put in new beds, put in new furniture and then repaint the walls.”

The check for bedbugs on Friday followed a more comprehensive investigation during winter break, when exterminators conducted a thorough walk-through of Alondra and destroyed all furniture and student belongings suspected to have been infested by the pests. The winter break examination was motivated by the discovery of bedbugs in several student rooms in early December, a discovery that forced the temporary relocation of several students to various dorms across campus.

At this point, however, bedbugs have only been found in one room, and the two dislocated students — Kropp and fellow freshman Leonard Parker — have been moved to the guest lounge in the Alondra basement. Kropp expressed relief that he was not relocated outside the dorm and took the move to the new room in stride.

“It’s still Alondra, so it’s not that bad,” he said. “It’s a little secluded, so I’m probably getting a little more work done.”
