Common Fall Pests Around Hayward Homes

Common Fall Pests Around Hayward Homes

While not entirely welcome, pests are just another normal part of nature. In Hayward, the most common pests homeowners deal with during the fall are rodents, stink bugs, boxelder bugs, Asian lady beetles, spiders, wasps, and ticks. Each pest enters properties for different reasons, which can make it hard to treat them all individually.

That’s where Mosquito Squad Plus of Northwest Wisconsin comes in to provide Hayward pest control. Rather than treating pests as separate problems, we offer treatment options that tackle multiple species at once to give you the peace of mind you want without the constant in-and-out hassle you don’t.

Rodents Looking for Shelter

Rodents are warm-blooded animals that often look for shelter as winter approaches. As a result, they often seek out residential properties in Hayward with dark, secluded areas where they can nest. Their most popular choices include garages, attics, crawlspaces, sheds, and wall voids, all of which become attractive as outdoor conditions change. 

But first, they need to find a way inside. Sure, they can sneak in through an open garage door when no one else is around, but more often than not, they’ll use small entry points that usually go unnoticed. These can be gaps, cracks, or voids in the foundation or eaves, which is why regular inspections are crucial. 

Overwintering Insects on Siding and Around Windows

Many nuisance insects, like stink bugs, boxelder bugs, and Asian lady beetles (often mistaken for ladybugs), overwinter and need shelter from Wisconsin's snowy, cold winters. Typically, they’ll show up in early fall on south-facing, sun-soaked siding and windows. 

From there, they’ll find a way inside to seek protected shelter and stay there until spring. The best way to prevent them is to target them when they first appear on your home’s exterior, before they can get inside. If they do get inside, vacuum them up, as crushing them can cause more issues and even stain your carpets and furniture.

Spiders, Wasps, and Other Late-Season Activity

Not all pests will try to break into your home to find shelter before winter. Some, including wasps and spiders, remain noticeable around structures or sheltered areas into fall, with activity changing based on the weather.

But still, backyard pest invasions stink when all you want to do is enjoy the last few warm days of fall before winter hits. To help you take back your yard, we can perform outdoor pest control treatments that target the areas in your space that attract pests.

Fall Yard and Home Preparation

Professional pest control is the best way to reduce pests around your home and yard in Hayward, but you can also do plenty of preventative tasks to prepare your home for fall. Here are some we recommend:

  • Seal any exterior gaps you find
  • Repair screens
  • Manage leaves and clutter
  • Secure food and trash
  • Inspect garages and storage areas for potential harborage opportunities
