What Are the Scariest Pests in Michigan?

The Scariest Pests in Michigan

Michigan is home to more of the scariest pests around than you might imagine. We play host to venomous spiders, aggressive predators, and something called an ASSASSIN BUG. These pests are different species, live in different environments, and want different things. The only thing they have in common is they all terrify.

These four Michigan-infesting baddies aren’t the most common, destructive, or even dangerous pests we contend with. Not this time. No, these pests are simply the pests we’d least like to find underneath a couch cushion or… in our beds. “We ain’t afraid of no pests,” of course, but even the hardest professional would think twice about approaching these top four scariest pests in Michigan:

Masked Hunter Assassin Bug

First of all: get a load of that name. We told you we weren’t kidding around about true “scariest” contenders here. The Reduvius personatus belongs to the assassin bug family (yeah, there’s a whole family) of insects. Masked hunters are small, glossy dark brown or black insects with wide abdomens, horizontal distinctive “beaks.” Along with their name and fearsome appearance, assassin bugs are scary because of how they feed.

Masked hunters prey on smaller insects like bed bugs. Their “beak” mouthparts are actually hollow and sharp, like a syringe. They stab this mouthpart into their prey, then use it to inject a digestive enzyme into the victim’s body. This enzyme literally liquefies their vicitim’s insides, which the bug then drinks up through its beak–like a straw! That’s… probably the scariest thing we’ve ever heard. Before you pack your bags and move away, you should know that assassin bugs can’t drink your insides. They will bite you if they feel threatened (it’s about as painful as a wasp sting), but that bite isn’t dangerous. That’s gotta be some solace… right?

Woodlouse Spider

This spider has a lot of nicknames: “sowbug killer,” “woodlouse,” “pillbug hunter,” “literally the scariest thing I’ve ever seen.” Females are about ½ to ¾”, while males are generally less than ½” long. Their many names reference the fact that woodlouse spiders are predatory. They hunt at night and primarily feed on sowbugs and pillbugs.

Woodlouse spiders are easy to spot for a couple of reasons. Their coloration is distinctive: adults have a purple-brown body and bright orange legs. These legs are arranged largely in front of the spider’s body, enabling it to run very quickly. They also have large, scary forward-pointing fangs. The spider uses these fangs like a pair of scissors to grab its prey. It’s unpleasant. Luckily, Woodlouse spiders rarely bite humans. Even if one did happen to bite you, the bite wouldn’t be medically significant (read: dangerous). Unfortunately, we can’t say the same for the next spider on our list…

Brown Recluse Spider

Yes, unfortunately, the infamous brown recluse spider appears to have taken up residence in Michigan. Brown recluses are also known as “violin” or “fiddleback” spiders because of the dark, violin-shaped mark on their backs. They measure about 1.3 centimeters long (about the size of a quarter), and appear brown, grey-brown, or tan in color. Unlike most spiders, brown recluses only have six eyes.

Unlike the Woodlouse spider, the Brown recluse isn’t just scary. They’re also one of the most dangerous pests in Michigan. Brown recluse spiders may administer a potent hemotoxic venom through their bites. This venom may cause fever, chills, rashes, nausea, vomiting, or even necrosis, or cell death. Fortunately, brown recluse spiders are, well, reclusive. They’re not aggressive and prefer to run or hide from humans. Brown recluse spider bites are very rare, even if the spiders live among people. Brown recluse spiders aren’t the only venomous spider in Michigan, however…

Northern Black Widow

Northern Black Widow Spider

You’re probably already familiar with the Black widow. They’re arguably the most infamously scary spider in the world, much less in the US. And one particular species, the Northern black widow (Latrodectus variolus) lives in Michigan. Northern black widows are about the size of a paper clip. They’re mostly black in color, except for an hourglass-shaped red marking on their abdomens.

Black widows are considered the most venomous spider in North America. The venom they can inject via bites is considered 15 times more potent than a rattlesnake’s. Black widow venom is a “latrotoxin,” which means it attacks the nervous system. Their bites can trigger nausea, vomiting, stomach pain, fevers, and even more severe symptoms. Luckily, black widows bite humans very rarely, and even when they do bite they don’t inject much venom. Black widow bites are rare, but if a black widow bites you, you should take it very seriously.

 

From the scary dangerous to the just plain scary, Michigan has its fair share of monster pests to contend with. Luckily, you’ve also got your own personal monster slaying force: Griffin Pest Control.

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.

Waterborne Pests and How to Avoid Them

Here in the upper Midwest, we don’t get too much beach time. Even if you live on a lake, you probably can’t get out on the water nearly as much as you’d like. To make matters worse, when the water finally gets warm enough to enjoy, waterborne pests are all-too happy to enjoy it with you.

Running into a pest outside or in your home is bad enough. Running into one in your water is the worst. Knowing how to avoid and prevent water pests from infesting your home will help give you peace of mind, so you can get back to enjoying your precious beach time.

 

mayfly

Mayflies

Mayflies get their name from their explosive emergence in May. They spend most of their lives as nymphs living in fresh water. Nymphs range in size from 3 to 30 millimeters (or .12 to 1.18 inches). They have six clawed legs, a slim body, gills, and two or three tails. Adult mayflies have famously short lifespans and live only to reproduce. They grow longer and more slender than nymphs, and their two pairs of pale wings become functional.

During mating season, mayflies swarm in huge numbers. Often, these swarms grow so large that they cover every surface in a wide area or create significant visibility issues for drivers. Mayflies are attracted to white incandescent and fluorescent lights. Replace white outdoor lighting with yellow bulbs. Consider drawing the blinds at night. If your mayfly problem seems particularly bad, UV light insect traps may prove effective.

 

mosquito on water

Mosquitoes

Yes, mosquitoes live in and around water. It’s just not fair! Specifically, many types of mosquito lay eggs in standing water. Mosquitoes need to stay hydrated to survive, which means they need to stay in places where the air is humid and damp. Both of these needs make lakes, rivers, and wetlands the perfect place for mosquitoes to live and breed. If they can get some of the blood they need to lay eggs somewhere nearby, so much the better.

The best way to prevent mosquito infestation in your home is to mop up standing water in your house or on your lawn. If you’re going out to the beach, bring some waterproof bug spray and reapply it every two hours. Try not to stay until dusk, when mosquitoes become more active. Bring along long sleeves and pants to change into after you’ve finished swimming.

 

cockroach in tub

Cockroaches

Like most of the other pests on this list, cockroaches love moisture and humidity. Cockroaches can survive for a month without food, but only two weeks without water. Unfortunate beach goers commonly discover them under wet soil, clinging to the base of a tree or other plants. Though they rarely go near the water itself, the environment lakes and rivers create is perfect for roaches to thrive in.

Roaches are scavengers, and they’ll eat anything they can get their hands on. They’re especially fond of bread crumbs, rotting fruit, and sweets. Outdoor picnics will tend to attract them in droves, especially if remains are left behind. At home, securely tie off or box up your pantry foods and wipe down counters and tables after meals. Cockroaches will take pretty much whatever they can get, so do your best to give them nothing.

 

giant waterbug

Waterbugs

Waterbugs are often mistaken for cockroaches, but there are some big differences–literally! First and foremost, size: waterbugs are a lot bigger than cockroaches. Lethocerus americanus, the most common waterbug in North America, ranges from 12 to 65 millimeters in length (1-2 inches long!). Unlike cockroaches, waterbugs actually live in water, swimming beneath the surface to catch prey. Cockroaches never bite humans, but water bugs are called “toe biters” because of their propensity to defend themselves with painful bites if disturbed.

Waterbugs need water. If they’re coming into your home, there’s a source available to them. Search your home for leaks, dripping faucets, or cracks that allow water in. Water bugs also fly toward light. These bugs get more active at night, when they fly around looking for new ponds or prospective mates. When you’re out, avoid spending too much time around lakes after dark, and be aware of where you step on the lake floor.

 

No two ways about it: water pests are freaky. No one wants to think about going for a swim, only to step on some gross bottom feeder. If you know a bit about the pests you’re likely to see, however, chances are they won’t seem as monstrous or dangerous to you. If you follow these steps, you may not have to see them at all!

If you’ve been struggling to keep waterborne pests out of your home or lawn for awhile and you’re at your wit’s end, give Griffin a call today! Whether they come by land, water, or air, we’ve got the perfect defense to thwart your pesky pillagers. Enjoy the beach!

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.

The Rats of Detroit and How to Stop Them

A recently conducted study found that Detroit is the Ninth most rat infested city in the US. Detroit’s rat population is on the rise.

Why are rat populations in Detroit becoming such a problem? Is there anything we can do to keep the population down, or least keep the rats out of our homes? Griffin wants to answer these questions, so you know where your rats might be coming from and what you can do about it.

Why Do Rats Love Detroit?

Like most pests, rats have simple needs and want to fulfill those needs as easily as possible. They flock to the parts of the world where the things they need are abundant, easily found, and as risk-free to pursue as possible. Cities like Detroit meet these criteria exceptionally well. Here’s what rats need, and how Detroit gives it to them:

Food

Most rats rarely wander further than their “home range” of 50 to 150 feet in any direction from the nest. Rats have poor eyesight, and prefer to know the environments they live in well to limit risk of predation or starvation.

A rat’s environment has to ensure that they can get enough food to survive while staying close to home. Cities solve this problem. High population densities create a lot of trash, which rats can use to feed themselves without ever leaving the nest. The next time you see a rat, check to see if there’s a dumpster nearby. Chances are, their nest isn’t far off.

Water

Just like pretty much everything else, rats need water to survive. Rats have to find a way to get a sustainable source of water close to their homes. It also has to be safe and relatively consistent, since rats are vulnerable while they drink. Cities solve this problem too.

Not only is there always a surplus of free water for rats somewhere, that water is often safe to linger around. Adult brown rats require only an ounce of water daily. Leaking pipes, broken valves, or condensation are more than enough to sustain them. Cities provide more chances to find water sources that can be accessed safely than any other environment would.

Shelter

The other thing all rats need to survive is warmth. When Winter comes, rat’s fur isn’t enough to protect them from freezing. They have to seek shelter in warm enclosures.

Cities provide for this need better than anywhere else, too. Old buildings, buildings that have fallen into disrepair, abandoned buildings, and unstaffed warehouses are all perfect places for rats to wait out the winter. They have all they can eat while they wait! The nooks and crannies of cities provide more safe shelter than anywhere else, and rats take advantage.

Keeping Them Out

Know that you know why rats are coming into your city, you can apply that knowledge to keeping them out. Rats go to places where they can easily get what they need. If you want to keep them away, you have to make sure they can’t.

Food

The most important way you can avoid attracting rats is by depriving them of food sources. Use tightly sealed, thick garbage bags to store and transport all your trash. Rinse out empty food containers before disposing of them. Keep your home’s garbage in a sealed container and keep it off the ground. Take your garbage out frequently, and make sure the dumpster you’re taking it out to is 15 feet or more away from your home.

Clean up your kitchen and dining surface immediately following each meal. Vacuum the rooms you eat in frequently and thoroughly. Make sure you put away groceries in their proper places. Don’t leave food out on the kitchen counter, especially not fruits or breads. Don’t leave snacks out after you’re finished with them, and don’t leave dishes in the kitchen sink.

Water

Once you’ve dealt with the food sources, look for places where rats could be getting water. Make sure you don’t have any leaking faucets, shower heads, or pipes. Invest in a humidifier for humid areas of your home. Look for drafts that could be letting air in. Make sure other water-based appliances like your dishwasher and refrigerator aren’t leaking either.

Finally, look for moisture. Make sure you’re always running your bathroom fan when bathing. Dry and put away dishes as soon as the dishwasher’s done with them. Rinse out bottles and cans before recycling them, even if almost all the liquid in the container is gone. Seal recyclables in bags and take it out frequently.

Shelter

Keeping food and water away will help, but if you really want to keep rats out, you have to make sure they have no way of getting in. Rats can squeeze through openings no larger than the size of a nickel, so don’t assume any cracks or gaps are rat-proof. Seal cracks in your foundation or walls with caulk. Replace worn weatherstripping, screens, and wooden frames. Make sure your windows and doors are properly sized and seated.

One of the most common places rats sneak in is around utility lines entering the building. Inspect that area and seal any gap you find between the lines and the house. Rats can also scurry up surprisingly steep surfaces such as trees to get on top of a house, so make sure your landscaping doesn’t create any likely paths to your roof. While you’re at it, try putting screens over your chimney and plumbing vent.

 

Remember: no matter how bad the rat problem, we can help you. We’ve been dealing with rats in Detroit and beyond for a long time, and we’re sure we can handle whatever they throw at us.
