Michigan’s Great Lakes Climate Creates a Perfect Storm for Year-Round Pest Challenges in 2025

Living in Michigan means dealing with one of the most unique climate systems in North America. The Great Lakes effect doesn’t just bring lake-effect snow and unpredictable weather patterns—it’s creating unprecedented pest challenges that homeowners face throughout the year. The Great Lakes have warmed faster than nearby air temperatures, leading to longer warm seasons and prolonged stratification, while reduced ice cover results in more winter lake-effect precipitation and increased winter wave activity.

Climate Change Amplifies Michigan’s Pest Problems

Extreme heat waves and cold spells on the Great Lakes have more than doubled since the late 1990s, with the appearance of these extreme temperatures increasing up more than 100% compared with before 1998. This dramatic shift isn’t just changing Michigan’s weather—it’s fundamentally altering the pest landscape.

Climate change is having an impact on ecosystems all over the world, and Michigan is no exception, with one of the most noticeable effects being the changing behavior of pests, which are becoming more abundant and more destructive than in the past. As temperatures warm, some pests are moving northward into regions where they were previously unable to survive, which can lead to new infestations and new challenges for farmers and other landowners.

The Great Lakes Effect on Pest Behavior

Michigan’s proximity to the Great Lakes creates a unique microclimate that affects pest activity year-round. During late fall and winter, cold air flowing over the relatively warm waters of the Great Lakes leads to the production of lake-effect snow, and as air temperatures continue to rise and further warm the Great Lakes, areas in lake-effect zones will continue to see increasing lake-effect snowfall as a warmer atmosphere will be able to hold increasing amounts of moisture.

This changing climate pattern directly impacts pest populations. Climatic warming tends to accelerate insect consumption, development, and movements, which can influence (and likely amplify) population dynamics via affects on fecundity, survival, generation time, and dispersal. The timing of life history stages (phenology) of many insect species has already been demonstrably advanced by warming temperatures, and there are growing examples of insect distributions extending northward.

Specific Pest Challenges Michigan Faces

Michigan residents are dealing with an expanding roster of pest problems. The black-legged tick (also known as deer tick), which is the primary vector for Lyme disease, is being impacted by climate change as warmer temperatures are allowing black-legged ticks to expand their range further northward in Michigan, making Lyme Disease a risk where previously it wasn’t present. Additionally, warmer temperatures are allowing ticks to become active earlier in the year, leading to a longer tick season.

Climate change is also impacting the behavior of mosquitoes in Michigan, as warmer temperatures and changing precipitation patterns, especially increased precipitation in many places, are leading to an increase in mosquito populations, which can transmit diseases like West Nile virus and Eastern equine encephalitis.

Forest pests are also becoming more problematic. Invasive insects and diseases, including hemlock woolly adelgid, beech bark disease and beech leaf disease, are taking a toll on Michigan’s forests, and the changing climate is further stressing trees and may lead to greater impacts by both invasive and native insects and diseases.

Year-Round Pest Activity

Traditional pest seasons are becoming a thing of the past in Michigan. By the end of the century, more frequent and intense severe weather, more flooding and drought risks, as well as more pests and pathogens will likely reduce crop yields. The extended warm seasons mean pests that once died off in winter are now surviving and reproducing year-round.

Increased heat wave intensity and frequency, increased humidity, degraded air quality, reduced water quality, and change in vector-borne disease patterns will increase public health risks. This creates a challenging environment where homeowners need professional intervention throughout the year.
