Seasonal pests in Ann Arbor, such as Brown Marmorated Stink Bugs, Boxelder Bugs, Asian Ladybird Beetles, Cluster Flies and some wasps exhibit a behavior we call “overwintering”.
In late summer and early fall they collect in larger numbers on buildings and crawl into cracks and crevices with the intent to hide there until spring. The warmer temperatures inside will draw them in causing activity throughout the winter and in early spring. By providing a thorough preventive treatment in late summer or early fall we can prevent this entirely. Some insects such as Carpenter Bees and Paper wasps show up reliably every spring and summer. These pests can also be prevented with an appropriately timed treatments. Read below to learn more about seasonal pests.
