86Bugs knows the Midwest region of the United States. Into November and beyond, colder temperatures drive various pests and bugs indoors as they seek warmth and shelter for the winter. Here are some common winter bugs you might encounter inside a home:
1. Boxelder Bugs
Here is an illustration of a boxelder bug, highlighting its black body with red or orange markings along the thorax and wings. 86Bugs can assist with this pest if you like. Contact us!
Boxelder bugs are black with red or orange markings and are particularly common around boxelder, maple, and ash trees. They don’t cause much damage, but they can congregate in large numbers inside homes, especially around windows. Cats absolutely love playing with these pests, until the cat knocks over your crystal figurines and break them all up. No bueno!
Asian lady beetles, often mistaken for native ladybugs, are an invasive species that cluster in large groups and can enter homes through small openings. They emit a yellowish liquid when disturbed and can leave stains and a strong odor.
3. Stink Bugs
Brown marmorated stink bugs seek indoor shelter to avoid the cold. They release a foul-smelling odor if crushed or disturbed. They don’t bite or cause structural damage, but they can be a nuisance. Cats LOVE playing with these pests and will chase them down, breaking your lamps as they go!
4. Cluster Flies
Cluster flies resemble house flies but are a bit larger and move more slowly. They gather in large groups, often in attics or unused rooms, and are attracted to warmth. They can reappear throughout the winter as they wake up from dormancy.
Various spider species, such as cellar spiders and house spiders, commonly seek warmth indoors during winter. They are generally harmless and can help control other insect populations.
6. Cockroaches
Some species, like the German cockroach, are active indoors year-round. Cockroaches seek warmth and moisture, especially in kitchens and bathroom.
Purchase a few glue traps (see below) and place in a few dark spots such as under sink / counter, under refrigerator where it is constantly warm, under / near garbage cans, near pet food storage and in the pantry. This will help you quickly determine if you do have cockroaches or other pests. If they are clean, move to other areas an wait a few days. Second area clean? You should be ok. Paranoid? Call us.
Silverfish are small, silver-gray insects that thrive in dark, damp places. They feed on starchy materials and can damage paper, clothing, and other items.
8. Carpenter Ants
While not as common indoors in winter, carpenter ants might venture inside in search of warmth if they’ve established nests in wooden structures.
9. Rodents (e.g., mice)
Although not insects, mice are common winter pests in the Midwest. They seek shelter and food indoors and can cause structural damage by gnawing on wires and walls.
Prevention Tips:
Seal cracks and crevices around doors, windows, and foundations.
Repair damaged screens and weather stripping.
Keep food in airtight containers and clean up spills immediately.
Use dehumidifiers in damp areas to make the environment less inviting.
Regularly clean and declutter areas where pests may hide, like basements and attics.
Managing these pests usually involves sealing entry points and keeping indoor spaces clean and dry.
