Late Summer Pest Infestations

The Pests of Late Summer

When you think about late summer bugs, chances are you picture them outside. When it’s hot and humid out, like it tends to be during Midwest summers, pests like rodents, centipedes, and spiders don’t have much reason to get into your home.

As soon as summer starts to end, however, pests start looking for a place to wait out the winter– a place like your home! Late summer tends to be the worst time of year for pest infestations for that exact reason. Here are a few of the sneaky snowbirds you can expect in the next couple weeks, and what you can do about them.

 

Rodents

Michigan’s rodents start preparing for winter early. They get aggressive in the pursuit of food, they start stockpiling resources, they dig burrows for themselves, and–of course–they sneak into homes. The earlier a rodent can find a warm, dry, dark place to nest over the winter, the better. As soon as the sun starts setting earlier, expect rodents to be hard at work preparing for cold.

Rodents will infiltrate a home by any means necessary, and they have plenty of means. First, they’ll look for cracks, gaps, and holes like openings in window sills, door frames, floorboards, or utility lines. Next, they’ll try burrowing to get at the foundations or insulation in the basement. More than anything, rodents target places where they can get food. Regular vacuuming and cleaning up after meals becomes even more important in the fall. You don’t want to advertise that your home is open for rodent business!

 

Spiders

Spiders begin mating around early September every year, which is one of the few things that will prompt them to leave their webs and get moving. Spiderlings in egg sacs stay warm during the winter. Adult spiders need to survive long enough to lay eggs, which means they need to find shelter. Between the need for shelter, the need to find mates, and the fact that a lot of their prey is fleeing indoors, homes start to look really appealing to spiders this time of year.

Spiders get into homes the same way other pests tend to: by finding their way through the cracks. Spiders are excellent climbers, so don’t think any crack or gap is too high or inaccessible for them. The best way to prevent spiders is to prevent other pest infestations. If spiders can’t hunt prey, they won’t want to hang around. Clearing away clutter will also help keep spiders from taking up residence.

 

Cockroaches

cockroaches tend to be active in the late summer and early fall

Cockroaches don’t hibernate, nor can they survive freezing temperatures for long. Both the common species of cockroach (American and German) highly prefer warm temperatures. American roaches seem to feel that 70 degrees is juuust right. Unfortunately, it gets worse. Like spiders, cockroaches tend to mate while sheltering indoors. They’re even known to settle in with their families after the egg sacs hatch. Any roaches that get into your home in late summer could be the first members of a multi-generational infestation.

Cockroaches want to live in confined, warm, dark, and humid places where they feel comfortable and safe. That means your basement, attic, and crawlspaces are prime real estate–especially if they’re messy or cluttered. It’s a good idea to organize and tidy up your basements and attics every late summer. Clear out anything you don’t need, organize boxes, and repair sources of undue moisture like humidity and plumbing leaks.

 

Stink Bugs

brown marmorated stink bugs tend to be especially active in late summer and early fall

Just because they’re a relatively new nuisance to Michigan doesn’t mean the Brown Marmorated stink bug hasn’t acclimated to their new home just fine. Unlike many pests that inflict themselves on Michigan households during late summer, stink bugs actually hibernate during the winter. They’re not mating and laying eggs in your home; they’re just sleeping. Even hibernating stink bugs can’t survive the cold, however, so before they hibernate they have to seek out shelter. They’ll even let themselves out in the spring!

Stink bugs frequently get into houses by squeezing under worn-out weather stripping, damaged screens, or gaps in window and door frames. Like spiders, stink bugs are very good climbers, so they’ve been known to use chimneys and air vents as access points, as well. Replacing chimney and vent screens will go a long way toward securing your home, especially if you replace worn weather stripping and window frames at the same time.

 

You’ve still got a little warm summer weather left, so now’s the perfect time to get proactive! Some simple preventative maintenance now could save you a big headache come winter.

Why Do These Pests Keep Coming to Michigan?

Michigan river in the fall. "Why do pests love Michigan?"

Griffin Pest Control has served Michigan since 1929, and since then we’ve been kept the same pests out of homes and businesses every single year. What is it about Michigan that keeps pests like these coming back? What do they find here that they can’t get anywhere else?

Like all animals, pests adapt to survive and thrive in their environments. The pests of Michigan keep coming back because they’re literally built to get everything they need from our environment. Understanding what common pests like these need to survive can help you learn how to deprive them of it. Then, they’ll go elsewhere for food and shelter.

Termites

The state of Michigan is 36 million acres of land. 20 of the 36 million acres of this land are considered forest. That means Michigan is one of the most heavily forested states in the country. 8 million acres of this forest is owned and protected by the government, meaning it hasn’t been developed or harvested. It’s the largest state forest system in the country, with three national forests, three national parks, two national wildlife refuges, and 2 million acres of open hunting and fishing land.

What does all that add up to? Trees. About 11.4 billion of them. As you’re probably all-too-aware, termites eat wood. Especially natural, growing or rotting wood. Michigan’s abundant and protected forests are a paradise for hungry termites, and unfortunately, so are any nearby homes.

stink bug

Stink Bugs

Like we covered last month, stink bugs are relatively new to Michigan, but we’re included them because they’ve quickly become a problem. The main problem species is the brown marmorated stink bug. This species is native to Asia and considered invasive in the US. It was first discovered in Michigan in 2010 in Berrien County. Stink bugs are notoriously good at proliferating by hitching rides with travelers by stowing away in luggage, bags, cars, or even clothes.

Stink bugs feed primarily on vegetable, fruit, nut, and legume crops, so they’re a big problem for Michigan farmers. While they aren’t nearly unique to Michigan, our climate, farms, and ecological diversity make the state a perfect environment for stink bugs to stink up.

bedbug

Bed Bugs

Bed bugs become a problem for any area that has a highly mobile populace, an older urban infrastructure, and/or a rural and urban areas in relatively close proximity. Michigan, like many states in America, has all of these. Bed bugs are even better at hitching rides with unsuspecting travellers than even stink bugs.

As people travel into and out of Detroit and Michigan’s other major cities, they often end up carrying bed bugs in and out, too. Once they make it to the big city, bed bugs find their way into buildings by exploiting the sorts of cracks and crevices that naturally show up in older buildings. Worst of all, bed bugs can be really difficult to get rid of, because they lay tiny eggs in great numbers and reproduce quickly. A lot of the bed bugs in Detroit have been living there for hundreds of generations.

boxelder bug

Boxelder Bugs

For boxelder bugs, the motivation is right in the name. This species of true bug (boxelder bugs are not a beetle, contrary to popular belief) feed almost exclusively on acer tree species like boxelder trees, along with maple and ash trees.

As you may have guessed, Michigan has a lot of acer trees. Unlike a lot of pests, boxelders need to hibernate in the winter. Boxelder swarms happen in Michigan around fall for two reasons: one, the eggs adult boxelders hatch on acer trees hatch. Two, because boxelders need to find shelter to get through the winter. Michigan winters get cold and come fast, so boxelders get desperate, and you see a lot of them around your house.

 

Every region in the world has its own ecosystem and its own unique set of pest problems. At least the pest problems we have generally come about because of how pretty and well-preserved our state is! If you have an infestation, however, chances are you’re not thinking too much about how beautiful Michigan’s forests are.

Luckily, Michigan also has us: one of the best pest control companies in the country. The next time you have a pest problem, no matter how minor or severe, give us a call today.
