Fall Pests That Want in Your Home

Mouse peeking through hole in attic wall

If it seems like there’s an increase in insects in and around your home in the fall, you’re probably right. It’s the result of pests trying to get indoors as the weather gets colder. Some pests migrate to warmer climates, some burrow in or under debris, while others just try to get into our homes to warm up. The scientific term for this phenomenon is overwintering. Pests will find a suitable area to settle in during the colder months and then become more active in the spring. 

This most directly affects you when fall pests enter your home. Some do this by coming in through small openings that are already present and others will chew their way in. There are several types of pests known to try to get in, from insects to rodents. The most difficult fall pests to get rid of are the ones you can’t see because they get in the attic or behind your walls. Read on to learn more about the common pests that may try to get in your home in the fall. 

Rodents

You probably know that squirrels are excellent climbers but did you know that roof rats and mice can also climb well? Most rodents will climb almost anything; branches, fences and drainpipes can all be used to access the roof of your home!  From there, it’s easy to get into your attic and make a nest to stay warm for the fall and winter. If you hear scratching or gnawing noises from up above or inside the walls, you likely have rodents inside your attic or wall voids starting to make themselves at home. Should this happen, it would be time to call an experienced rodent exterminator like the specialists at Griffin Pest Solutions. It is also advised that you ensure your home is properly sealed to help prevent rodent entry. A mouse can enter an opening roughly the size of a dime! Squirrels will chew on dormers and fascia boards to make their own entry points. 

Asian lady beetles

While Asian lady beetles resemble ladybugs, they’re somewhat larger. Their coloration ranges from red to orange and not all of them have spots. So, what’s the problem with these small ladybug look-alikes? They hang out together in large groups, using pheromones to communicate their location. When they decide to enter your home to get warm, the result can be a large infestation that ends up in your attic or walls. While they won’t directly cause harm by damaging your home or stinging you, there are unpleasant side effects. Should you end up with an infestation, lady beetle waste can stain and is known for triggering allergic reactions or breathing difficulties in sensitive individuals.

The best way to prevent these, or any bugs, from getting into your home is to seal cracks and crevices on the exterior of your home. Asian lady beetles are small, so you’ll need to be diligent should you choose to take on this task. Having a preventative pest control service in place can also help to prevent a pest infestation from taking place in your home. If a product is applied to your home consistently, it doesn’t allow for an infestation to even begin. 

Stink bugs

While there are several types of stink bugs, the brown marmorated stink bug is the one you’re most likely to see in your home. It’s an invasive species originally from Asia. They’re shaped like a shield and their color is a mottled combination of brown and gray. They range in size from ¼” to ⅜”. As their name suggests, when stink bugs feel threatened or get squashed, they release an unpleasant odor. Stink bugs tend to spend the winter in quiet parts of a home where they’re unlikely to be disturbed like an attic, crawlspace or inside the walls. 

When you see these pests walking on your home or nearby trees, it is easy to forget that they can fly and it’s their wings that bring them to your home in swarms at times. You will first start to notice these fall pests as the temperature starts to cool at night but the days are still warm. Stink bugs will land on the sides of your home, where the sun is warming the siding, this helps them to stay warm as well. They are drawn to lighter-colored homes, which can be the reason you are seeing them but your neighbor doesn’t have any issues.

Wasps

A whole wasp colony doesn’t overwinter, just the queens. The worker wasps won’t survive the winter and the queen will start a new colony every year.  The fertilized queens overwinter outdoors in places such as hollow logs, stumps or under leaves. However, they can also overwinter on or in structures, including the attics or siding of homes. The most common way for wasps to get in is through attic vents that aren’t screened. If you haven’t done so lately, look for openings into your attic and seal them as much as possible to help prevent wasps and other pests from entering. It is possible for the queen to start her new colony in your attic, which can mean a large nest of wasps could end up inside!

Why Do I Have Stink Bugs This Winter?

Stink bug during winter

Stink bugs typically enter a state of dormancy called diapause in winter. Unless, of course, they can find a heat source to sustain them. If they do find a heat source–say your home–they can remain active all year. Any stink bugs in your home will seek hiding places to wait out the winter. They’ll almost leave you alone… but the smell might not.

Obviously, nobody wants stink bugs in their house in winter, but how do you get rid of stink bugs? Especially if you have an infestation? And what draws them to some buildings over others? Here’s how you can find (and remove) stink bugs in your home this winter:

Signs of Stink Bugs in Winter

To tell if you have a stink bug infestation, look for these signs that they may be nearby:

  • Live bugs. Stink bugs’ bodies are brown or black and shaped like a shield. They have spots of lighter coloring around the edge of their body, six legs, and antenna. If you see one, then there are almost certainly more nearby. If you see one moving around inside your home, then you probably have an infestation. 
  • Dead bugs. Pay attention to the entry points in your home, including door frames, windows, and baseboards. Stink bugs congregate around heat sources, especially in fall and winter. When they find cracks and gaps around these heat sources, they push and squeeze their way through. Sometimes, not all the bugs will make it all the way through. You might find the bodies of less-fortunate members of the party around door and window frames, baseboards, and utility lines.
  • Stink. Stink bugs… got their name for a reason. When they feel threatened, these bugs secrete a foul-smelling liquid in defense. If you smell a pungent odor like rotten vegetables or cilantro, it may be a stink bug. Stink bug liquid secretions are a pale-yellow color and can stain surfaces over time. They also use this scent to attract others when to sources of food and shelter.

Why my home?

Stink bugs come into homes looking for shelter, water, and food. Their preferred food source is sugar and they’re fond of overripe fruit. They’ll also congregate around the food waste in trash cans or beneath cupboards and the dishwasher. 

Sugar isn’t the only stink bug draw. They also gather around light and other heat sources. They’ll be particularly noticeable at night, when you’ll see them scurrying around outdoor light bulbs or indoor lamps. Food or heat sources could be reasons why you have a stink bug problem.

How to Prevent Stink Bugs

Keep stink bugs from bothering your property by taking some of the following steps: 

Keep stink bugs from bothering your property by taking some of the following steps: 

  • Minimize outdoor lighting. Don’t keep any outdoor lighting on unless it’s necessary. The more bugs your lights draw to the surface of your home, the higher the odds that at least some of the congregation will find its way inside.
  • Rub your window screens with dryer sheets. This sounds weird, but it’s an easy prevention tactic. The fragrance of your average scented dryer sheet is unpleasant to a stink bug. Rub them on your window screens when doing regular cleaning as a simple exclusion effort. 
  • Fix plumbing leaks. Stink bugs are drawn to moisture they can access without drawing attention to themselves. This is most easily found near hidden plumbing leaks in faucets and pipe joints and under counters and cabinets.

How to Get Rid of Stink Bugs

Stink bugs will usually naturally leave your home in spring when they re-emerge from dormancy. We recommend leaving the cracks and crevices where they might enter diapause in your home alone until then. If you seal up their hiding places, stink bugs will die inside your home. When stink bugs die, they secrete their odor–which contains a pheromone that attracts more stink bugs. They also secrete this odor when you crush them or when they find good hiding places.

If you notice active stink bugs inside, vacuum them up (don’t crush them!). Dispose of the vacuum bag outside of your home. Whenever you remove bugs from a surface, clean that surface with ammonia and/or soapy water. This will help remove pheromone secretions and keep more the bugs away. Focus on exclusion methods until you’re sure all the stink bugs are gone. If you trap or kill too many of the bugs, it’ll only exacerbate your problem.

Stink Bugs, How to Get Rid of Them for Good

Do stink bugs die in winter? Not if they’re in your home. Obviously, we understand if you don’t want to simply wait until spring for your stink bugs to leave your home.

Winter Invaders to Watch Out For

Mouse in snow

You could call this time of year in Michigan “the dead of winter.” It certainly often feels that way, especially on one of its many dark, dreary days. Despite how it may look and feel outside, however, not everything really is dead. As you probably know, pests are nothing if not tenacious.

No matter how cold or dead the winter, pests will muddle on long enough to bother you. It would almost be inspirational, if it weren’t so annoying. Here are four pests that are probably trying to warm themselves up inside your home right now.

stink bugs

Stink Bugs

Stink bugs are infuriatingly common in Michigan. Part of the reason why they’ve managed to stick around is that they’re good at staying warm during winter. They do that by sneaking into people’s homes for shelter starting in early fall. Stink bugs congregate around windows and other warm places all fall. While they’re gathered, they find cracks and gaps around frames and siding. They use these gaps to work their way inside.

Inside, stink bugs enter a hibernation-like state called diapause for extended periods of time. While in diapause, the bugs remain completely immobile and don’t need food or water. In order to remain safe while in diapause, the bugs seek out hiding places. The stink bugs in your home may be in your walls, around your rafters, or in other secluded areas. They won’t hurt your home while they’re around, but they may produce their distinctive stink.

cluster flies

Cluster Flies

Cluster flies look a lot like common house flies, but they’re bigger, rounder, and slower. They may make a buzzing noise when they fly around. The name “cluster flies” refers to the flies’ tendency to cluster together in large numbers. Starting in late summer and early fall, they gather in groups to stay warm. As the temperature drops, they make their way into cracks and gaps around siding and awnings. Eventually, these cracks may lead them all the way inside.

Like stink bugs, cluster flies may enter prolonged periods of diapause after entering your home. These flies usually enter your home from high up, so they’re common in attics and rafters. You may find them around window or door frames, or near vents and utility lines. Cluster flies wake up during warm days to move around. They can’t hurt you or damage your property, though they may attract other pests like spiders. Cluster flies usually leave your home in spring.

rodents

Rodents

Rats and mice cannot hibernate. To survive winter, they need to find a warm place where they can access food and water. Rodents are very sensitive to temperature and pressure changes in the atmosphere. They begin infiltrating homes as soon as they sense fall approaching. Rats and mice squeeze through small gaps around window and door frames, utility lines, foundation, and siding. They find these gaps by using their acute senses to find drafts and follow the smell of food.

Rodents can’t fly like stink bugs or flies, so they usually end up in your basement. They’re attracted to any source of moisture or food. Rats and mice grind their teeth by chewing on a wide variety of soft materials. They can ruin boxes and fabric, damage furniture, or even cut electrical wires and start fires. Both rats and mice may reproduce indoors if given the chance. If you have a rodent infestation, you should deal with it fast!

boxelder bugs

Boxelder Bugs

Boxelder bug behavior is quite similar to stink bugs’. Starting in fall, they begin to gather around warm places. They’re particularly attracted to homes with southern and eastern exposure, for the sunlight. As they congregate, they may naturally slip into gaps and cracks around windows and doors. When winter comes, they will move further through the cracks to stay warm, eventually ending up inside. Boxelder bugs have very flat bodies that enable them to squeeze through tiny areas.

Boxelder bugs remain generally inactive during winter. They don’t reproduce inside and they won’t live long enough to survive winter. Boxelder bugs may emerge from their hiding places to sun themselves during warm days. When that happens, you may find them near windows or other warm areas. Boxelder bugs aren’t dangerous, but they may secrete a liquid that could stain surfaces when threatened or crushed. You may encounter more boxelders in early spring, as they begin to leave your home.


The reason why pests want to get inside your home over winter is so they can stay warm. The colder (and longer) the winter, the more desperate these four pests become. Believe it or not, however, you can turn that to your advantage.

Pests don’t have time to waste trying to break into a fortress this winter. If you can pestproof your place, you can keep pests away all season long. We want to help. If you have a pest problem this winter, give Griffin a call any time. We’re always happy to drive pests out of your home, no matter the time of year!

Pests That Wake Up in Spring

Pests that wake up in spring

The whole world seems to come back to life in spring. Unfortunately, “the whole world” includes some things we wish would stay sleeping. Along with grass, flowers, trees, and birds, a whole host of Michigan’s most annoying pests wake up every spring.

When pests wake up in spring, they’re usually hungry, thirsty, and ready to find mates. To make up for their long winters off, they tend to pursue these activities ferociously. Their single-minded pursuits make pest problems all-too-common this time every year. Here are the pests you’re bound to run into this spring, what they’re up to, and the problems they cause.

Boxelder bugs

boxelder bugsStarting in early fall, boxelder bugs go looking for dry, warm places where they can wait out the winter. Unfortunately, those dry, warm places often include our homes. When spring comes around, boxelders become active again to seek their newly rejuvenated food sources and, eventually, to reproduce. When that happens, they vacate their winter hideaways en masse. If they were hanging out in your home over winter, you’re going to run into them again this spring.

Boxelder bugs are obviously a nuisance, but luckily they’re not a dangerous one. These pests don’t bite, spread disease, eat fabrics or stored foods, or lay eggs indoors. Instead, they simply vacate the premises to seek the seeds and flowers of acer trees like the boxelder. The nuisance part comes from how many of the gross bugs you may notice vacating. Boxelder excretions and feces may also stain window ledges and other favored areas.

Stink bugs

stink bugsStink bugs follow a similar seasonal routine to boxelder bugs, and they’re around for the same reasons. During fall, they desperately seek out any warm place where they can wait out the winter. Once they’re in position, they go dormant until outdoor temperatures rise back up to survivable temperatures. Once that happens, they wake up with one thing on their mind: mating. In their mad scramble to get back outdoors, however, they tend to get lost… or stuck.

Like boxelder bugs, stink bugs don’t reproduce or nest indoors, cause disease, or bite. They do… stink, however. When threatened or crushed, stink bugs secrete a foul-smelling substance from a special scent gland. This scent smells like rotten vegetables or coriander. The more stink bugs secrete at once, the more powerful the stench. These secretions can also leave behind a dark yellow stain on carpets, furniture, or window sills.

Carpenter ants

carpenter antsDuring spring, the infamous wood-infesters come marching in to build their nests and search for water. Carpenter ant invasions tend to be the most noticeable during the start of the season. Starting in mid spring, the reproductive carpenter ant castes swarm in order to seek mates and start new colonies. After mating, queen ants seek good places to lay their eggs. These eggs hatch into workers, and the infestation begins in earnest.

Carpenter ants are a problem because they make their colony nesting grounds by boring through wood. The tunnels they carve compromise the structural integrity of wood products. Carpenter ants don’t actually eat the wood they infest. Instead, they have to hunt for sources of protein and sugar. You may find foragers in your kitchen, basement, or garden. Keep a close eye out for swarmers, in particular. If these flying ants get trapped in your home, chances are their nest is also inside your home.

Pavement ants

pavement antsUnfortunately, carpenter ants aren’t the only ants reproducing and foraging in the spring and summer. In late spring, the brief but very active pavement ant mating season begins. During this time, you may notice swarms of larger-than-average, reddish-black ants flying in large clusters. After mating, pavement ants lay eggs in tight crevices (hence their association with pavement, and the cracks in it). When young pavement ants emerge, they start looking for food almost immediately.

Pavement ants are most often encountered in groups in your kitchen. They break down and carry off all sorts of stored food, especially grains and sugars. When they find food, they tend to stick around. It’s not uncommon to find ants infesting cabinets, pantries, cupboards, and anywhere else they could find food. They’ll attack any scraps they can get their mandibles on. Unlike other pests on this list, they can stay active as long as they’re warm and they have food.

 

Spring should be a wonderful, refreshing time of year–especially after a brutal Michigan winter. Don’t let pests ruin that for you. If you need some help fighting back an infestation so you can enjoy the nice parts of spring again, give Griffin a call. We can deal with the dirty work so you can enjoy the rest.

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.

Next time you need help clearing out an infestation, or making sure you never get one, give Griffin a call today. We’ve helped thousands of Michigan residents before, and we’re always happy to help you too.

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.
