What Could a Potential Super El Niño Mean for Ann Arbor's Winter Pest Activity?

Ann Arbor winters are typically fairly cold, but can have more mild stretches, depending on the year. A potential Super El Niño could make those temperature swings more significant, even reducing the number of cold days Ann Arbor sees during the season. Mosquito Squad Plus of Greater Lansing can help homeowners build the most appropriate Ann Arbor, MI, pest control plan without assuming a warm winter.

What Exactly Is a Super El Niño?

El Niño is a weather condition that is the result of warm Pacific waters influencing weather patterns inland. Super El Niño is an informal term to describe an exceptionally strong El Niño and may increase the likelihood of milder winters. This does not mean there will be no snow, ice, or freezing temperatures, however.

Why Might Stink Bugs and Boxelder Bugs Reappear?

Stink bugs and boxelder bugs commonly slip into sheltered spaces during fall, sometimes settling behind siding or inside wall voids. You might spot stink bugs crawling near a window or boxelder bugs gathering on a sunlit exterior wall. If the sun is out and temperatures are mild, you may even see stink bugs inside as the walls they are hidden in warm up.

Could Ticks Stay Active During Mild Winter Spells?

Not every tick species becomes dormant in fall and winter. Deer ticks, especially, reach adulthood in the fall, and as long as temperatures remain above freezing, they will be seeking hosts. If a super El Niño results in mild weather stretches, deer ticks will be more active than some may anticipate.

Ticks like to spend time in shaded greenery, waiting for new hosts to pass by. You can help limit their hiding spots by trimming back brush and keeping leaves and thick landscaping away from common areas you may spend time in.

What About Rodents?

Mice and other rodents are less likely to be roaming during cold weather, but they don't need it to seek shelter. Rodents are driven by food and will look for small openings to gain access to warmth and food. Check for gaps in the foundation or around garage doors. Even utility lines can have enough space for mice to squeeze through. Rodent control can help address activity indicated by droppings, gnawing, or nesting materials.

Does a Warmer Winter Automatically Mean More Pests?

Moisture, snow cover, food sources, and species-specific habits all impact winter survival and movement. A short thaw period can make pests more visible, but it doesn't mean their numbers are increasing, just that their routines are changing. Seasonal pest concerns are not always an infestation. Behavior changes can feel overwhelming or frustrating to homeowners.

How Can Ann Arbor Homeowners Prepare?

Get ahead of pest behavior changes by taking maintenance tasks before the weather starts to change. Check seals and screens, close cracks, and look for gaps around pipes without blocking needed ventilation. Keeping firewood or patio furniture stored away from the foundation can limit access to the house; rodents and spiders like to hide amongst these densely stacked items when looking for entry.
