A walk through the woods is no longer the only place Midwesterners should watch for ticks.
Researchers say the tiny parasites are spreading to communities across the region and show no signs of slowing down.
According to the Centers for Disease Control and Prevention, emergency room visits attributed to ticks are at the highest levels in nearly 10 years. The Midwest is the region with the second-most likely emergency room visits due to tick bites.
In 2023, state health departments reported more than 89,000 cases of Lyme disease in humans to the CDC, the most recent year numbers have been published.
Experts like Edward Walker, a Michigan State University entomologist who has tracked changes in tick populations across Michigan and the Great Lakes region, warn the increase may not go away anytime soon.
“This is a long-term process of expansion in the range of ticks,” Walker said. “It’s not just that there is more this year than last year. It’s a much bigger, longer-term thing.”
In places where ticks were once rare, expansion of the species continues.
