Tick populations are increasing in Michigan | WKAR Public MediaTick populations are surging across the U.S., particularly in the Northeast, Mid-Atlantic, and Upper Midwest, leading to increased tick-borne diseases. Driven by climate change, milder winters, and expanding habitats, these pests are thriving in urban and suburban areas. Key factors include rising deer/rodent populations, reforestation, and habitat fragmentation.

Key Reasons for Tick Population Growth
Climate Change: Warmer temperatures, higher humidity, and shorter winters allow ticks to survive, stay active longer, and expand into northern regions.
Host Availability: Rising white-tailed deer populations provide critical, consistent food sources for adult tick reproduction.
Habitat Changes: Suburban development and reforestation create "edge habitats" that support higher populations of host animals like white-footed mice, which are major carriers of Lyme bacteria.
Invasive Plants: Some invasive plants (e.g., Japanese barberry) create ideal, humid microclimates for tick survival and shelter rodents.

Impact on Public Health
Increased Disease: Tick-borne diseases, such as Lyme disease, have more than doubled in the U.S. over the past two decades.
Expanded Geography: Black-legged (deer) ticks are rapidly expanding their range into new areas, including parts of Canada.
Seasonality Shift: Tick-related emergency department visits have increased, with significant surges observed in early summer.

Protection and Prevention
Tick Checks: Perform thorough body checks after being outdoors, particularly in woody or brushy areas.
Repellents: Use EPA-registered insect repellents (such as those containing DEET or picaridin).
Landscaping: Create a barrier between wooded areas and lawns, and remove leaf litter to reduce habitat.
