HONOLULU (HawaiiNewsNow) – For weeks, students at Kalaheo High School in Kailua say thousands of critters have been crawling about campus.

Videos posted on social media showed throngs of millipedes along the school’s outdoor areas and in its gymnasium.

“It’s really gross, there’s just like millipedes all over the walls and it’s just gross, they’re crawling everywhere, and like I’m walking and I have to walk over them,” senior Cate Carmack said.

Carmack’s classmate, Lex Fuentes, added, “They’re just like all around our school. like on the ceiling, walls, floor, they’re just everywhere.”

Fuentes and Carmack both did not really mind the millipedes, but they said the swarms were somewhat distracting.

“I was sitting in AP psych, just doing my thing. I see it on my jacket, flick it off, and I go about my day,” Fuentes said.

Junior Harper Reynolds shared that some were seen on the roof and walls.

“When I’m walking around, or like going from class to class, there’s just like millipedes on the roof and on the walls. It’s kind of weird, it’s kind of gross, it’s like, why is that even there?” Reynolds said.

The pests are likely there because of the recent rain, according to Jimmy Fitzgerald of Kilauea Pest Control, which sprayed infested areas of the school on Tuesday.

“Kalaeho’s been very impressively proactive handling this over the years because every spring, that’s very common, the boom in insects, the rain is coming, it’s pushing them outside of their natural habitat,” Fitzgerald said.

This year, the insect’s natural habitat, the hillside behind the school, is much more saturated from the Kona low storms. Fitzgerald said the wetter conditions this year could explain why there are more millipedes at the school than usual.

“Naturally, the millipedes would be going up the trees, and hiding in the trees for a day and then coming down, but it’s been so wet in those back areas, they’ve been coming into the human spaces instead,” Fitzgerald explained.

Fitzgerald also pointed out the pests are harmless, and so is the insecticide they use to get rid of them, as the product is safer and less toxic than household bleach.

“Everything we do is people and pet-friendly, so it’s meant to impact something that’s this small, millipedes are about this small,” Fitzgerald said.

Kilauea Pest Control used a long-lasting product expected to push out the pests over the two to three weeks.

The company will reevaluate in 30 days whether the school will need a follow-up treatment.

“It needs to be gone,” Carmack said.

The Hawaii State Department of Education reported “the problem has dramatically decreased” since Tuesday’s treatment and “school custodians are continuing to monitor the campus and will respond to any new reports.”
