'They're Feeding On Our Skin': Black Fly Outbreak In Eastern Washington

SPOKANE, WA - They suck blood, and their bites cause swelling, bleeding, and welts. They attack in swarms and can easily crawl under your clothing. But the worst part? You might never see the attack coming.

There has been an increase in reports of biting black flies attacking people in Eastern Washington and other parts of the Inland Northwest, according to the Spokane Regional Health District. The extremely tiny flies - sometimes called "no-see-ums" - are active near bodies of water when its cloudy and humid out.

In one terrifying incident recorded by the Spokesman-Review, a mother and two children were attacked at the Dishman Hills Natural Area east of downtown Spokane. Within minutes of the attack, one of the children had bites all over her neck and forehead, and she was bleeding.

“It’s as if they’re feeding on our skin!” the young girl said, according to the mother.

Experts believe there are more flies around this year because of heavy precipitation over the winter.

Due to the increase in reports of black fly attacks, the Spokane Regional Health District has prepared a tip-sheet to help people avoid getting bitten. Here's what they advise:

• Avoid areas where black flies are active during the day, especially at dusk and dawn.
• Wear light-colored long pants and long sleeves, especially whites and tans. Also wear a light colored hat.
• Consider using insect repellent to reduce your chance of being bitten.
• If you are bitten, clean the bite and apply topical products to reduce itching. Avoid scratching to reduce chances of infection.

Although black flies are a gross nuisance, they do not transmit disease, according to SRHD.
