Will a Warmer Winter Mean More Pests in Chesterton?

Chesterton winters can fluctuate between lake-effect snow, bitter cold, and mild afternoons. The shifting conditions impact pest behavior and where they seek shelter in the fall and throughout winter. A potential El Niño could bring milder conditions to the region, so understanding the impact temperature fluctuations have on Chesterton, IN, pest control can help homeowners anticipate seasonal problems.

What Could a Super El Niño Mean for Northwest Indiana?

El Niño develops when tropical Pacific waters become unusually warm, impacting weather patterns inland, farther than you may think. Indiana is not exempt from El Niño weather changes, which can result in milder winters near the Great Lakes. This does not mean winter will be milder the entire season; snow and bitter cold are still probable.

However, extended above-average temperatures can influence changes in seasonal pest activity. Species may have periods of increased activity when seeking shelter or emerging to find food.

Could Ticks Be Active Between Cold Snaps?

As blacklegged ticks do not reach maturity until fall, these ticks are likely to remain active on mild winter days, seeking hosts and moving through surviving landscaping. Fallen leaves are common shelter points for ticks during fall and winter, so rake and dispose of them properly. During mild stretches of weather, you might want to spend time outside. Remember to check over people and pets for ticks that may have grabbed on. Adult blacklegged ticks may seek hosts on mild winter days when temperatures rise above freezing.

Why Might Stink Bugs and Boxelder Bugs Reappear?

Stink bugs and boxelder bugs are nuisance pests, not damaging structures, while seeking warmth. They may leave behind stains or a foul odor if squashed, so vacuuming is a better option for removing them. These pests can be frustrating when the attempt to get inside leads to large numbers gathering around doors and windows. During milder weather, they could emerge from wall voids or other nooks where they are sheltering.

Do Rodents Still Look for Indoor Shelter?

Mice and other rodents may investigate the house or garage for shelter and more reliable access to food and nesting materials. Rodents like to use cardboard, insulation, and stored fabrics to create their nests, sheltering and breeding throughout the winter. Milder weather may result in their emergence from these nests, so keep an eye out for droppings or gnaw marks that could indicate current activity. Rodents can use exceptionally small gaps to get inside, so check weather stripping around garage doors and seal accessible gaps.

Does a Mild Winter Mean More Mosquitoes in Spring?

This is not necessarily the case, as mosquito activity relies on a combination of spring temperatures, standing water, and other conditions. Before snowmelt and spring rain, clean gutters and turn over containers that collect water. When the regular season begins, recurring mosquito barrier treatments help control up to 85-90% of mosquitoes for up to 3 weeks. Applications every three weeks help maintain control as outdoor activity picks up.

Prepare for Changing Conditions, Not Just the Forecast

Take the time to inspect common entry points and shelter pests may use in the fall and throughout winter, regardless of temperature.

• Inspect screens
• Tighten garage door seals
• Repair dripping spigots and direct water away from foundations
• Store firewood away from exterior walls

Take note of where pests appear in the fall as temperature drops. The first mild day after a stretch of cold weather can indicate where pests are overwintering and identify where repairs or pest control can be useful.
