How to prevent, treat itchy bites from cicada-loving mites

( NewsNation ) — Tiny mites could be behind the itchy red rash afflicting people in regions where broods of cicadas swarmed this summer.

The noisy, periodical insects that shed their exoskeletons and scaled local trees aren’t responsible for bites reported in areas like Chicago , Ohio , Kansas and Washington, D.C. — but they’re not completely off the hook. Experts say the culprit is an undetectably small mite that feasted on cicada eggs, which the bugs laid in conditions perfect for mite reproduction.

Pyemotes bites cause a red rash that surrounds itchy bumps or welts, according to the Illinois Department of Public Health. They often appear on exposed parts of the body like necks, shoulders and arms. Those who have been bitten may find relief in over-the-counter antihistamines and itch creams. They should also resist scratching the affected area to limit the risk of infection.

Avoiding the mites can be tricky because of their size and the way they come in contact with humans. Since they tend to feed where they somewhat randomly land, bug spray and DEET may not be enough. Health officials say wearing sleeves and showering with soap and warm water after being outside can help fend off the microscopic insects.

The problem may resolve itself soon as cicada eggs hatch and the mites disappear, NewsNation’s local Chicago affiliate WGN reported .

However, cicadas aren’t the only insect feeding the small bugs, known in some areas as oak leaf itch mites. They also feed on fly larvae commonly found on pin oak leaves , and the effects of their bites can take 10 to 16 hours to develop.
