Common Seasonal Pests in Wisconsin
Seasonal pests are a persistent concern for homeowners, as certain species become more active during specific times of the year. In Wisconsin, pest control presents unique challenges because the warmer climate keeps pests from entering full hibernation in winter, allowing them to remain active for longer periods.
The combination of warmth and humidity in Wisconsin also speeds up pest reproduction, leading to higher populations, especially during the summer. Essentially, every season here can feel like pest season, though some pests are more noticeable in certain months. Understanding these patterns can help homeowners prepare for the pests they are most likely to encounter.
Each season tends to bring its own set of pests, which we’ll explore in the sections below:
- Birds: As insects become more active in the spring, so do birds, their primary food source. In Wisconsin, birds can be a nuisance because their nest building clogs gutters and causes water damage.
- Ants: Ants are especially common in Wisconsin. They become more active during the spring months. Their colonies grow rapidly as the weather warms.
- House Centipedes: House centipedes prefer dark, moist environments and are often found in bathrooms and basements. Known for their many legs and quick movements, they can spread fast if not dealt with promptly.
- Snakes: Although usually nocturnal, snakes become more active during the day in spring due to wetter weather and rising temperatures.
- Millipedes: Millipedes tend to invade homes more frequently during or after heavy rainfall, seeking shelter from wet conditions outside.
- Termites: Termites are well-known for causing damage to wooden structures in Wisconsin homes and show increased activity in the spring season.
- Bed Bugs: Increased summer travel provides more chances for these unwelcome pests to spread, often leaving behind itchy bites and causing discomfort.
- Bees, Wasps, and Hornets: While bees play an essential role in pollinating our blooming landscapes, wasps and hornets can disrupt outdoor activities with their aggressive behavior.
- Cockroaches: Cockroach populations grow quickly in warm weather, with German, American, and Oriental species being the most prevalent in Wisconsin.
- Fleas, Ticks, and Mites: These pests often hitch rides indoors on pets and are known carriers of diseases like Lyme disease, which is common in our area.
- Flies: The longer and warmer summer days invite flies to become persistent nuisances around your home and family.
- Mosquitoes: Our region’s warm, humid weather creates ideal conditions for mosquitoes, which can carry illnesses such as West Nile Virus.
- Asian Lady Beetles: As temperatures drop, Asian Lady Beetles seek shelter indoors and can form large infestations.
- Boxelder Bugs: When daytime temperatures start to cool, Boxelder Bugs often enter homes, favoring sunlit areas.
- Spiders: After their summer breeding season, spiders such as the Brown Recluse and Black Widow become more noticeable. Both species are found statewide.
- Stink Bugs: To escape the cold, stink bugs, particularly the Brown Marmorated stink bug, find their way indoors. They are often seen near doors and windows, especially in urban and suburban neighborhoods.
- House Mice: As temperatures drop, house mice often invade homes in search of warmth, becoming a more noticeable problem during colder months.
- Norway Rats: Known for their adaptability, Norway rats tend to move indoors when the weather cools, seeking shelter from harsh outdoor conditions.
- Silverfish: These shimmering insects are commonly found in pantries and food storage areas, especially as cooler weather sets in.

Is It Possible to Avoid Seasonal Pests in Wisconsin?
You have some control over how many seasonal pests appear, but eradicating them completely is difficult. This dual nature of being both predictable and unpredictable means it’s important to stay proactive with pest control.
For optimal pest control, consider these recommended seasonal prevention tips:
- Seal Entry Points: Seal potential entry points like window sills and doorways to prevent pests from gaining access.
- Inspect Items: Thoroughly check any items you bring indoors from outside to avoid accidentally introducing pests.
- Keep Clean: Maintain a tidy home environment both inside and out to reduce places where pests can hide and breed.
- Control Moisture: Address any excess moisture promptly, as damp areas attract many types of pests.
- Get Professional Help: When needed, don’t hesitate to contact a pest exterminator for comprehensive inspections, targeted treatments, and lasting prevention.
How Do I Prevent These Fall Pest Infestations?

Given the nature of these occasional invaders, the best way to protect your home is to prevent them from getting inside in the first place. They are active for a short period of time, so be sure that all prevention methods are applied before the first frost.
- Keep the area around the foundation of your house clean and free of debris.
- Repair and replace any torn screens on windows and doors.
- Trim any overhanging branches or overgrown shrubs near your home.
- Repair and seal any cracks and crevices around windows, eaves, doors, insulation, and siding.
- Pay close attention to places where pipes and wires enter your home.
- Sprinkle food-grade diatomaceous earth around entry points and other vulnerable areas. This natural substance is abrasive to pests but safe for humans and pets.
Some essential oils, like peppermint and lavender, are natural pest repellants. Mix a few drops with water and spray on windowsills and at entry points. Not much can be done beyond vacuuming them up once these pests are inside.
