The Most Common Pest Problems in Michigan

The Most Common Pest Infestations in Michigan

Every human-populated region on earth deals with its own host of pest problems, and Michigan is no exception. Many of the same features that make Michigan so great–our forests, our interconnected metro areas, our proximity to water–also bring pests from far and wide. Some of these pests comprise a serious, long-lasting threat to the health of the local ecosystem. Some are just out to ruin your day.

We’ve talked at length about the first variety before, so now we’re covering the problems a bit closer to home. These are the four varieties of pest that you’re most likely to encounter in your home. Chances are, you’ve dealt with at least one of these ne’er-do-wells before–even if you didn’t realize it. Here are the Michigan pest “usual suspects”, and how to keep them from bothering you.

Stink bugs

stink bugThe brown marmorated stink bug is Michigan’s newest nemesis, but it’s more-than made up for lost time. The stinky pests are mostly a problem for farmers, since they’re notorious for eating crops. They really only bother households during the fall and spring, when they’re either looking to get warm or trying to get back outside. Even if they infest homes, they don’t reproduce indoors, inflict property damage, or eat human food or fabrics. If you’ve never had them before, you’d be forgiven for thinking stink bugs don’t sound like “pests” at all!

Then you remember what they’re called. When crushed, threatened, or congregated, stink bugs secrete a gross-smelling liquid from specialized glands. The more of it there is, the stronger the smell. Stink bugs often congregate around sunny perches by the hundreds. The best way to deal with stink bugs is by vacuuming them up and throwing out the vacuum bag. Afterward, wipe down surfaces stink bugs walked over to remove the scent and pheromones they may have left behind.

Rodents

rodentsAdmittedly, mice and rats aren’t just the among the most common of pests in Michigan. Anywhere people live, chances are mice and rats are scampering around trying to live alongside them. They’ve been at it long enough, in fact, that rodents have evolved into the ultimate human-home infiltrators. Mice and rats use their sense of smell and amazing ability to sense minute air currents to find ways into homes. They don’t need to find much either; mice and rats can squeeze through unbelievably tiny openings.

Mice and rats may live in your home all year, but they’re particularly prevalent in early to mid fall. As soon as they sense the season begin to change, they’ll start looking for a warm shelter. Rodents use small openings around foundations, utility lines, or window and door frames to get into homes. Finding cracks and gaps like these and sealing them up is the best way to prevent future rodent problems today.

Carpenter ants

carpenter antsDespite being equally prevalent, carpenter ants are often mistaken for their cousins the sugar, pavement, or field ants. Unfortunately, though carpenter ants may look like their less-distressing cousins, they don’t behave like them at all. Most ants may be content to pursue your home’s food, but carpenter ants have another prize in mind: your home itself. Specifically, the wood your home is made of. Carpenter ants are second only to termites in terms of their wood-destroying, property-damaging potential.

Unlike termites, carpenter ants don’t eat the wood they destroy. Instead, they simply tunnel through it to build their ever-expanding colonies. The ants infest wood that’s moist and easy to bore through, so the best way to prevent them is moisture control. Ensure your plumbing isn’t leaking and your attic, basement, and crawl spaces aren’t too humid. Dispose of any water-damaged wood as soon as you find it, so that carpenter ants won’t.

Bed bugs

bed bugsAs we’ve explained before, everyone’s least-favorite bedfellows have had quite the renaissance in recent years. After developing resistances to the chemicals used to kill them, bed bugs began repopulating at a startling rate. Even worse, the bed bugs’ natural inclination to hide in cramped, dark, and warm places means they are nature’s ultimate hitchhiker. Before we knew what hit us, Americans had transported bed bugs all over the country by plane, train, and automobile. Unfortunately, Michigan wasn’t spared even a little.

Contrary to name and reputation, bed bugs don’t just infest beds. Instead, they gravitate toward any location that’s dark, sheltered, cramped, warm, and near food. It just so happens that beds tend to satisfy those requirements–you’re the food! Find bed bugs by looking for bloody or dark patches on sheets and linens. Prevent them by changing and washing your sheets frequently, and by thoroughly inspecting luggage you bring into your home.

We realize it can’t be comforting knowing that your home state plays host to such a rogue’s gallery. That’s why we’ve decided to end on a bit of good news. Griffin Pest Control has been fighting these common pests right here in Michigan since 1929. As you might suspect, all that practice has made us pretty darn good at it.

Intercepting Stink Bugs in the Wintertime

Intercepting Stink Bugs

Unlike many other pests in our part of the world, stink bugs don’t infest homes during the spring or summer. Instead, Michigan’s newest neighbor tends to start infesting homes in late fall and early winter. If you see a stink bug in your home come early spring, it’s probably because it spent winter with you.

We know that’s not exactly great news. Stink bugs survive winter by getting cozy in shelter and basically going dormant until spring comes. But, as we keep our homes nice and warm, it’s not uncommon to see a few stink bugs in your home during the winter. If you don’t want to run into them in a few months, you should consider intercepting them now. Here’s everything you need to know to do it.

How They Survive

How stink bugs survive winterWhen temperatures drop, stink bugs enter a special hibernation-like state called diapause. Diapause dramatically slows down the stink bug’s metabolism, allowing it to survive without food for long periods of time. Instead of feeding, stink bugs in diapause burn through nutrients they spent the spring and summer stockpiling. Basically, they fatten themselves up for winter just like squirrels.

Stink bugs have to enter diapause in winter because the fruits, seeds, and nuts they feed on aren’t available. It solves their food problem, but they’re on their own when it comes to the cold problem. Stink bugs are native to Southeast Asia, and never developed adaptations to help them survive cold. Even if they entered diapause outside, their bodies would freeze and they would die. Unfortunately, that’s where your home comes in. Stink bugs try to sneak into structures for one reason: to keep warm and sleep away the winter.

Where They Go

where stink bugs go in winterStink bugs enter buildings via the same access points most pests find. Usually, they crawl through cracks and crevices around door and window frames or utility lines. Stink bugs fly and climb surfaces, so they may use vents, chimneys, or roofing damage to get in, as well. It’s only after stink bugs infiltrate a home successfully that their behavior becomes a bit more unique.

When stink bugs enter diapause, they can’t move and only have a minimal awareness of their surroundings. They have to be very careful about where they enter diapause if they ever want to wake back up! Once inside, stink bugs shack up in the quietest, most inaccessible or forgotten part of your home. They might be in air vents, under appliances, behind walls or flooring, or even hiding inside furniture. You’ll probably never find stink bugs inside unless you go looking for them.

Are they a Problem?

are stink bugs a problem in winter?No. When stink bugs enter homes, it’s only ever to stay warm while they sleep away the winter. They don’t eat or infest your food, damage structural material, create nests, mate, or lay eggs. In fact, stink bugs won’t begin their mating season or lay eggs in spring until after they’ve left your home. Pretty considerate of them, really. The pests don’t transmit diseases or harm humans and pests in any other way, either.

That being said, there is the matter of their name. Stink bugs… stink. When threatened or startled, they secrete a foul-smelling liquid from a scent gland. The scent has been compared to cilantro or coriander. The secretion is mostly harmless, though it may trigger allergic reactions or stain fabrics in concentrated amounts. Stink bugs may also produce a pheromone that attracts other stink bugs to their location. A lot of stink bugs aren’t any more dangerous or destructive than a few, but they are stinkier.  

What To Do About Them

what to do about stink bugsFirst, vacuum up the stink bugs you find with a shop vac. Remove and dispose of the vacuum bag into an outdoor dumpster when you’re finished. Clean the surfaces where you find stink bugs with soapy water and a washcloth. Try not to crush stink bugs when you find them, because they’ll release their scent on death. Remember to check the secluded or hidden areas where stink bugs like to hide. Cleaning these areas regularly will make them far less attractive to the pest.

When you’ve removed all the stink bugs you can find, focus on locating where they got in. Look for cracks and crevices around baseboards, door and window frames, the foundation, or insulation. Seal up cracks with caulk to prevent additional bugs from following residual scent left behind by the first infestation. Stink bugs’ bodies are quite flat, so even small cracks provide them with enough room to sneak through.

 

Stink bugs aren’t the most disruptive of winter pests, but you shouldn’t have to share your home with them. Come spring, any stink bugs you don’t find now will make themselves apparent, often in upsetting ways. Luckily, by getting to know stink bugs and following these steps, you can ensure that doesn’t happen.

And if ever you need some help ensuring that doesn’t happen, you know who to call. We’ve been fighting stink bugs since they showed their ugly mugs in Michigan, and we’re pretty good at it. Give us a call anytime and we’ll make sure you head into spring smelling good.

Preparing for Fall Pests

Preparing for fall pests

Earlier this month, we listed four of the most common pest infestations that happen in late summer. Each of these pests had something in common: they were all trying to get out of the cold. Unfortunately, these pests don’t stop trying to sneak their way to warmth just because it’s fall. In fact, they only try harder.

Fall is the perfect time for preventative pest maintenance because it’s warm enough that you can still go outside and get work done without freezing. The earlier you pest-proof your home, the fewer pests will be able to use your home as their own personal winter vacation pad. Here are four simple things you could do this fall to minimize your risk of a winter-long pest infestation. Winter is rough enough on its own!

Yard Work

doing yard work this fall will help prevent pest infestation

If your yard gets bogged down in long, dying grass, fallen leaves, or untrimmed bushes and shrubs, opportunistic pests WILL find it. It would be bad enough if hordes of pests just hung around eating your yard and making themselves a nuisance, but they won’t just stay there. When it starts getting colder, they’ll be all-too-happy to move right in.

Rake up fallen leaves to avoid having soggy piles build up in your yard. Mow your lawn short until it stops growing, and don’t forget to trim your bushes. Pests often use decorative yard plants as ladders, so it’s a good idea to keep a border of at least 3 feet between the edges of your home and plant life. As winds pick up and temperatures drop, pick up fallen debris from nearby trees and shrubs. Finally, make sure your yard isn’t absorbing too much moisture. There should never been puddles of stagnant water on your property.

Border Maintenance

reinforcing borders and other entrances to your home will help prevent pest infestation this fall

While you’re outside, take the time to walk the perimeter of your home. Look for any small cracks or gaps pests could use to get inside. These cracks won’t always look the way you’d expect. One common way pests get into homes is by crawling up utility lines like pipes and electrical wires. They follow the line and squeeze through small gaps where the utilities enter the home. Pests like spiders and cockroaches can even crawl through plumbing vents and chimneys on the roof.

First, caulk over the gaps around utility lines. Then, check each window and door frame and sill. Replace old weatherstripping, make sure doors and windows are seated correctly, and check for drafts. Window frames tend to be particularly vulnerable, so check them thoroughly and repair them as necessary. Don’t forget about windows in the basement or attic, either. Make sure you’ve got all the entrances covered–big and small, high and low–and you’ll go a long way toward a pest-free* winter.

Decluttering

cleaning up your basement can help prevent pest infestations this fall

Clutter doesn’t just help pests while they’re outside. The messier your home is, the more places pests have to hide and nest. Cluttered, junk-filled basements provide all kinds of the dark, confined, humid places that pests love, and they’re really good at seeking them out. It’s easy to let things pile up in your basement, attic, or storage place, especially in the winter. Remember, however: the longer you go without cleaning, the more comfortable pests will feel living in your home.

Everyone knows about “spring cleaning”, but no one ever talks about “fall clean up”. You should change that. Go through your basement, attic, closets, and other storage places this fall. Clean out anything you don’t need. Organize everything you’re keeping and make sure it’s in a safe, secure place. Pests are shy by necessity, so the harder it is to find shelter in your home, the less they’ll want to stay. We guess you could say you’re making your home “scary” clean!

Good Habits

Developing good anti-pest habits will help prevent infestation this fall

Probably the most important thing you can do to keep pests away is to develop some good anti-pest habits. It’s not enough to spend a couple days in fall over-preparing for pests like a student cramming the night before a test. You’ll experience much more success (and fewer pests!) if you keep up with your anti-pest regimen all fall and winter long.

First, don’t let clothes, food, boxes, or other junk pile up in your basement, mud room, or garage. Take the garbage out to the dumpster as soon as it’s full, and keep it in plastic bags. Dispose of anything pungent or compostable in the dumpster right away, instead of letting it sit in the dumpster. Get routine maintenance problems like plumbing leaks dealt with as quickly as possible. Pick up yard clutter in the snow every now and then, even if it’s cold out. Store firewood away from the house, never up against it.

 

Fall is pest season crunch time. Our rodential rivals and insectoid irritants will be doing absolutely everything they can to stay warm over the winter, so we’ve got to do everything we can to keep them out.

Following steps like these during your “fall cleanup” (yes, we’re making it a thing) will go a long way toward keeping even the most desperate and creative of pests out of your home. And remember, in the unfortunate event you do end up with an infestation, don’t panic! Just give Griffin a call. We’ll seal things up and get pests out.

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

rats are active in late summer and early fall

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

the brown recluse spider may be active in late summer and early fall

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.

termite on wood

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.
