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.

4 Fall Projects for Keeping Boxelder Bugs Away

Fall is prime time for boxelder bugs, as they try to sneak into your home to escape the winter. Every year, they show up in literal droves, congregating on warm surfaces and sneaking through tiny gaps. Unfortunately, their prevalence, tiny size, and flat bodies make boxelders a particularly common indoor infiltrator. Fortunately, they’re not nearly as difficult to keep out if you know how.

Boxelders use the same old tricks to get inside homes every year. They rely on worn-out defenses, tiny gaps, and neglected weatherproofing. If you can brush up on your home’s anti-pest defenses this fall, you’ll deprive boxelders of these tired tricks. Here are four easy projects that will seriously help keep boxelders–and other pests!–away this fall.

Install Door Sweeps

A door sweep is a long strip of rubber or plastic that’s attached to a thin metal plank. Door sweeps essentially block the small gap between a door and its threshold without impeding the door’s function. When you shut the door, the long strip pushes into the threshold gap. As you open the door, you push the strip away from the gap. Installing door sweeps helps keep doors energy efficient. They also help with pests like boxelders.

Boxelder bugs are surprisingly flat insects. They can fit through or (in this case) under smaller gaps than you’d expect. Often, boxelders squeeze beneath the threshold of exterior doors to get into your home. Installing door sweeps on exterior doors is a particularly easy way to prevent that. All you have to do is measure the width of each door and buy sweeps in corresponding sizes. Installing your sweeps is easy too; all you’ll need is a drill and the sweep’s instructions.

Weatherstripping

Replace Weatherstripping

Weatherstripping is material (rubber, plastic, vinyl, tape, etc.) used to seal gaps between windows or doors and their frames. All of your home’s window and door frames probably have it, even if you don’t know it’s there. Weatherstripping compresses when the window or door closes, sealing off the gap between the moving parts and the frames. If it’s working correctly, weatherstripping completely seals the window or door when closed, leaving no gap whatsoever.

Over time, weatherstripping naturally wears away. Weather and cold beat it down, and opening and shutting doors can damage it. When weatherstripping wears out, it can no longer create a perfect seal around windows or doors. Boxelders can use openings between weatherstripping and frames to get inside. Check on the weatherstripping around your doors and windows. If it comes off easily or looks worn, replace it. Sealing your window and door frames is one of the best ways you can keep all pests out.

Seal Off Utility Lines

By utility lines, we mean plumbing pipes, gas lines, electrical wiring–any infrastructure that enters your home from outside. There are small openings all around your home where these important utility lines enter it. Unfortunately, sometimes those openings aren’t small enough. Often, pests like boxelder bugs will follow a pipe or electrical wire straight through these small gaps. From there, they could end up in the walls, the insulation, or even in your basement or attic.

It’s a good idea to know where all of your utilities enter your home. Look for plumbing, electrical, heating and cooling, and gas lines both inside and outside. If the gap between a pipe or wire and the wall looks too wide, it is. Remember: boxelders can fit through the tiniest gaps you can see. Use some heavy-duty caulk to seal up gaps around your utility lines. Rodents and other pests love following pipes inside, too, so you’ll be pest-proofing for more than just boxelders.

Garage door seal

Replace the Garage Door Seal

A garage door seal is basically weatherstripping for your garage door. The seals are long strips of (usually) rubber that fit across the entire underside of the door. When you close the garage door, they compress into the ground, forming a complete seal between the door and ground. There are also seals on the sides and top of most garage doors. When it’s working correctly, garage door seals prevent pests from sliding beneath the door and into your garage.

Garage door seals wear out about as quickly as other weatherstripping, and for the same reasons. Luckily, they’re also about as easy to replace. If you have your garage door’s instruction manual, look up info on the seal inside of it. If you don’t, just measure the length and width of your door. You can install garage door seals yourself, or have a professional garage door installer put it on for you.

It’s tough to keep from seeing boxelder bugs this fall. If there’s an acer tree near your property, it’s hard not to see them everywhere. Just because they’re everywhere doesn’t mean they have to be in your home, however. By performing a little maintenance like the projects listed here, you can keep boxelders out this fall and beyond.

If it turns out you need a little help keeping boxelders at bay this fall, give Griffin a call. We can make sure boxelders–or any other pests, for that matter–don’t bug you this fall.

Boxelder Bugs in Spring

Boxelder bugs in spring

When is it not boxelder season? It seems like these gross red-and-black bugs are everywhere, all the time. Around this time of year, however, you may notice they’re around even more than usual. Boxelders wake up and start moving around starting in early spring. Unfortunately, they often wake up and start moving around in your home.

But why are boxelders around your home so much this spring? Where are they coming from? What do they want? Most importantly, how can you get them to go away? Here’s everything you need to know about boxelder bugs in spring.

What they are

What boxelders bugs areEven if you don’t know boxelder bugs by name, you almost certainly know them by sight. These bugs are extremely common in the fall and spring, when they swarm around windows, porches, and door frames. Boxelder bugs are a type of “true bug” in the Hemiptera order, similar to stink bugs. Like stink bugs, they can also release a foul-smelling scent if threatened or crushed. Despite these similarities, however, boxelder bugs are not considered stink bugs.

Boxelder bugs have .5 inch long black bodies with distinctive bright red or orange ‘X’-shaped markings on their backs. They tend to congregate on warm, heat-reflecting surfaces such as windows or porches in large groups. Boxelder bugs feed almost exclusively on the flowers, leaves, and seeds of boxelder trees. These bugs enter reproductive season in mid-spring or early summer, shortly after re-emerging from winter hiding places. Homes with southern or western exposure might be particularly attractive to boxelder bugs.

Why they’re back

why boxelders return in springLike stink bugs, boxelder bugs never really leave Michigan. Instead, they overwinter in hidden, secluded places where they can survive the cold. Boxelders survive winter temperatures by bunching together and squeezing into tight nooks and crannies. They seek out warm, dark places where they can remain unnoticed and dormant for months at a time. Unlike stink bugs, they don’t fully enter diapause. During warm enough winter days, boxelders may temporarily re-emerge.

Boxelder bugs re-emerge from their winter hiding places as soon as they can survive outdoor temperatures. In other words, the boxelders you find in your home in spring were probably there all winter. Boxelders are very temperature-sensitive and crave warmth, so they’re commonly found around sunny windows and reflective surfaces. The bugs congregate in large swarms in order to keep one another warm and exchange information via pheromones. These swarms may sometimes get trapped or lost inside homes as they try to find their way out.  

What they want

what boxelder bugs wantWhen boxelder bugs re-emerge from the overwintering sites, their top priority is food. Remaining inactive for long periods is very taxing to boxelder bugs, so they need to recharge quickly. During this period, adult boxelders are usually encountered on the ground, where they eat low vegetation and fallen seeds. Boxelders seek out female acer trees for their plentiful fallen seeds and flowers. Boxelders don’t begin mating until they’ve acquired enough energy from feeding, which can take weeks.

Once boxelder bugs find their way outside and acquire sufficient energy, they usually move to a nearby acer tree outside. From there, they lay eggs, eat, and prepare to begin the whole cycle again. Like stink bugs, boxelder bugs do not eat, mate, or reproduce indoors. They only enter buildings in order to stay warm, and they’re only interested in leaving come spring. Boxelders aren’t dangerous, but their stench and sheer number can make them a serious nuisance.

What you can do

what you can do to prevent boxelder bugsThe most important thing to remember about boxelders control is that when they die, their bodies attract other pests. Don’t kill the boxelders you encounter in your home, especially if they’re in your walls. Instead, vacuum or sweep up the boxelders you encounter and dispose of them outdoors. You could also use soapy water to kill the boxelders, as long as you remove the bodies after they die. Scrub down any areas where boxelders congregated with soapy water, too.

After you’ve cleared out the existing boxelders, you have some time to make sure they don’t come back. Boxelders won’t try getting back into your home until early fall, when they need to overwinter again. Before this happens, try to find and seal off the ways they get in. Boxelders usually find cracks and crevices near window sills, door frames, and baseboards. Use caulk to re-seal these openings, and you should be able to keep boxelders from getting in next season.

 

Don’t beat yourself up for having boxelders in your home this spring. Those little pests are as tricky and resourceful as they are smelly. There’s a reason there are so many of them.

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.

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.
