Mysterious microscopic bugs infesting Ore. 1st-grade classroom

BEAVERTON, Ore. -- There's a mysterious bug infestation at McKay Elementary School. It's caused bites and rashes on several children in the first grade within the last three weeks.

The bugs are microscopic, according to Beaverton School District spokeswoman Maureen Wheeler. Wheeler said at least two pest control companies have been to the school but they can't figure out what the bugs are or where they came from. One of those companies sprayed the infested classroom, but the spray didn't get rid of the bugs.

A specimen has now been sent to Oregon State University and first grade students have been moved to the gym for class.

The district only communicated with families of first grade students until Thursday, when they planned to send a letter home to all of the students' parents.

"If I see any bites, I'll probably be concerned about it and probably question the school what's going on," one parent told KATU News.

Another said, "Even if it's just the first grade classroom, it makes me a little nervous. I don't want them coming home."

One first grade student said his friends were bitten, but all he knows about the mystery bugs is they are "these things that bite you."

Since they are microscopic, that's really all the district knows, too.

The school says there are no reports of bugs spreading to other classrooms or students' homes.
