How to Prepare Your Kalamazoo Home for a Potential Unpredictable El Niño Winter

Kalamazoo winters can shift quickly from snow to a muddy thaw. A potentially powerful El Niño could make the temperature swings typical of this time of year more impactful. There is a possibility of fewer cold days in Kalamazoo, impacting the behavior of many different overwintering pests. Mosquito Squad Plus of Southwest and South Central Michigan understands how those temperature shifts can affect pests seeking shelter and the level of activity you may see.
What Is a Super El Niño?
El Niño results in an alteration of weather patterns across North America. It starts with warming waters in the central and eastern Pacific, pushing warm air inland. Super El Niño isn't an official term for a weather event, but an informal description of an exceptionally strong El Niño. It could influence winter temperatures around the Great Lakes as well as moisture levels, impacting the habits of many common pests.
What Might Happen Around the Great Lakes?
Strong El Niño winters often tilt the odds toward milder conditions across the northern United States, including the Great Lakes. Kalamazoo can still see cold snaps, ice, and lake-effect snow. Thaws followed by freezes can put extra strain on buildings, while warm spells can reveal insect activity.
Seal Small Openings Before Temperatures Drop
Walk around the perimeter of the house looking for potential entry points. Check for damage or gaps and repair as needed. Places to check:
- door sweeps
- window frames
- foundation gaps
- openings where pipes or cables enter
Make sure you are examining under and behind landscaping where cracks may go unnoticed. Take note of existing signs of pest presence, leading you to entry points you may not have considered.
Watch for Bugs Around Sunny Windows
Some pests will emerge during milder weather, seeking sun-warmed surfaces to rest on. Stink bugs and boxelder bugs are two such species, usually found around windows and doors when not seeking direct sunlight. These pests may shelter in foundation cracks, or squeeze through small gaps to rest inside wall voids. During an unusually mild winter afternoon, they may appear indoors near windows even if they have been hidden for weeks.
Manage Moisture and Yard Debris
Ticks seek out sheltered, humid resting places to wait for hosts or slow down through colder weather. Keep up with landscaping throughout the fall and prepare for winter by trimming back branches and grass. Keep an eye out for blacklegged ticks, one of the more commonly found species during winter.
Think Ahead to Spring Mosquito Activity
A mild winter alone does not guarantee a larger mosquito population in spring. It may lead to earlier emergence, but that is not a sure thing. Warm temperatures and moisture have the largest impact on mosquito populations, so before snowfall and subsequent snowmelt, store buckets and tarps to avoid water gathering in them. Once the regular treatment season begins, recurring mosquito barrier treatments help control up to 85-90% of mosquitoes for up to 3 weeks, with visits scheduled every three weeks.
Prepare Your Kalamazoo Home for Whatever Winter Brings
It isn't always the best choice to plan a winter checklist solely based on one forecast or the possibility of a 'typical' winter. Taking steps to prepare for multiple eventualities can set you up for more reliable pest control. Sealing gaps, repairing damaged screens, and focusing on controlling moisture can help prepare your home.
