Hornets, mice, and other pests to watch out for this fall

In the fall season, crawling insects and small animals crawl out of the ground and into cozy places where they might try to stay over the winter.

Nick Stokke, owner and technician at Prairie Pest Control, said hornets, crickets and grasshoppers are some of the most common buzzing and chirping noises around homes in the Lakes Area at this time of year.

Fargo-based Prairie Pest Control has serviced residential, commercial, and lake properties in parts of Minnesota and North Dakota for the past four years; Stokke itself has 10 years of pest control experience.

“It’s definitely been a crazy year for them (hornets), they really thrive in the heat and drought,” says Stokke. There are many hiding places for hornets, e.g. In piles of stones, wooden stakes, or under a cement slab or deck, but you might spot a large group of hornets, see one fly to a nest, or find an exposed nest.

Hornets, along with flies and crickets, buzz around in early autumn and stay with the leaves. Stokke says keeping your garden free of leaves, dead grass, and other debris is important to keep these pests away. He also recommends not having long grass.

“You just want to keep your yard or house around free and free of as much clutter as possible, and that will really help you either prevent something from coming in or it will help you notice more, like it used to be … if you have any problems, ”he says.

Other insects you might notice around the house more often in the fall include Asiatic ladybugs, which cluster in ceiling corners for warmth, and cluster flies, boxelder bugs, western conifer seed bugs, and others. You can spy on these bugs snaking around your walls and window sills.

Spiders are also entering more houses from autumn onwards. Lake and river properties are particularly vulnerable to spiders, according to Becky’s Pest Solutions of Wadena, which serves central and northern Minnesota. Treatments used on the outside of a house prevent spiders from going inside.

For mice, there is unfortunately no simple prevention like this, and it doesn’t take long for a mouse problem to get worse: Mice reproduce quickly, with up to 10 litters per year of six to 12 babies each, Becky’s Pest Solutions says. In addition to obviously invading your home, mice leave dirty droppings and can transmit fleas, ticks, and mites.

“With mice … in the fall there always seems to be a little bit more in the huts or houses – you know, sometimes people see mouse droppings or they might see the mouse itself running around.” outside of the house, ”says Stokke.

While spotting pests is not always easy, Stokke says the company is available to answer questions such as:

“We’re always there to help, whether it’s a question about a specific pest or… we have some people who just call us and say, ‘Hey, what’s that bug? Is that a problem? ‘”Said Stokke.
