The threat of Lyme disease is growing, with ticks now spreading across regions once considered safe. As deer populations grow, so does the risk of exposure to Lyme-carrying ticks. Whether you’re out for a hike or simply enjoying time in nature, it’s important to stay informed about where Lyme disease hotspots are emerging.

Deer Populations Fueling Rising Lyme Cases

In areas where deer populations are thriving, tick populations are also booming. The Northeast, including states like Maine and New Hampshire, is seeing a sharp increase in Lyme disease cases, driven by abundant wildlife. With peak tick season coinciding with summer outdoor activities, taking precautions in these regions is more important than ever.

Woodlands and Suburbs Create Ideal Conditions

Ticks are making their way through more parts of the Midwest, particularly in Michigan, Illinois, and Wisconsin. The blend of rural forests and growing suburban neighborhoods in these states creates an ideal habitat for ticks to thrive. If you’re exploring nature trails or hiking, remember to check for ticks afterward to minimize your risk.
