Which Pests Overwinter in Grand Rapids Homes and When Do They Become Active Again?

As temperatures drop in Grand Rapids, many pests look for protected places to spend the colder months. Garages, basements, attics, wall voids, and exterior gaps can all provide shelter. Grand Rapids, Michigan pest control starts with understanding what pests will be seeking shelter to overwinter in and around your home. Mosquito Squad Plus of Grand Rapids can help homeowners with the right pest control plan as well as information on when to expect pest activity to ramp up.

Which Pests Overwinter in Grand Rapids Homes?

Overwintering pests vary depending on the region you live in, but there are a few common ones throughout Michigan.

• Ants: Some ant species may move into sheltered spaces closer to the house as temperatures drop. It's more common to find them around the foundation or building nests under decks. These are sheltered spaces that help retain heat.
• Stink bugs: stink bugs are not damaging, biting pests, but they can be frustrating and, when disturbed, may release a foul odor. Stink bugs will start attempting to get inside the house to shelter from colder temperatures, but will usually be seen gathering on the sun-warmed siding or brick of the structure first.
• Spiders: Some spiders remain active indoors through winter when insects and protected hiding places are available. Basements, garages, utility rooms, and storage areas can provide suitable conditions.
• Mice: Rodents do not become dormant for winter. Mice that enter a house can remain active throughout the season while searching for food, water, and nesting material.

Seal the Exterior Before Winter Settles In

One of the easiest ways to limit pest access to your home as temperatures drop is to seal cracks or small entrances you may not expect. Make sure you are inspecting window and door frames, the foundation, anywhere cables or pipes enter, and even around siding edges.

Any damaged or degraded seals should be replaced or repaired, including window screens and door sweeps. One thing homeowners may not think of is trimming back vegetation from windows and the foundation, limiting direct access for pests.

Pay Extra Attention to Garages and Entry Doors

Garages frequently provide an easy transition from the yard to the house. Check the bottom and sides of the garage door for gaps, inspect seals around service doors, and keep stored materials organized so pest signs are easier to see. Bird seed, grass seed, and pet food should be kept in tightly closed containers. Attracted to the available food, rodents may try to establish nests in the garage. If you notice droppings or gnaw marks, it may be time to look into professional pest control options.

Make Basements and Attics Less Inviting

Basements and attics can stay undisturbed for long periods, giving pests places to hide. Vacuum webs and debris, reduce clutter, and address excess moisture or leaks. Fresh webs that return quickly after cleaning may indicate current spider activity, while insect remains can suggest a steady food source nearby.

When Do Overwintering Pests Become Active Again?

As long as temperatures remain above freezing, there will be some pest activity outside, but the majority of pest activity will begin to ramp up as temperatures warm in the spring. Overwintering pests will begin leaving shelter spaces, so it may feel like they have appeared out of nowhere as they leave. Our team can help with planning routine pest control as temperatures continue to rise.
