What Brings House Centipedes Into Homes?

A house centipede scurries across the floor of a Michigan home. Contact Griffin Pest Solutions to get rid of centipedes before they take over your home or business.

With their many legs and rapid movements, house centipedes (Scutigera coleoptrata) tend to startle anyone who spots them. Although they aren’t harmful to humans, their sudden appearances can be unsettling. If you’ve noticed one racing across the floor, you’re probably wondering what led it inside and why it chose your home of all places.

The reason is pretty straightforward: house centipedes are looking for shelter, moisture, and a steady food supply. If your home checks all those boxes, it becomes an ideal environment.

One Tiny Opening is All it Takes

These insects don’t need a wide opening to get indoors. Their slim, flexible bodies and quick reflexes help them slip through narrow spaces with ease. Cracks in the foundation, gaps around utility lines, uncovered vents, loose exterior siding, and worn-out window seals are all common entry points. Once they’re inside, they gravitate toward cool, dark corners that offer protection and access to food.

Because they’re nocturnal, house centipedes typically stay out of sight during the day. If you spot one, chances are it’s been hiding in the basement, under sinks, or behind large appliances for a while.

They’re Chasing Their Next Meal

These pests usually prefer to remain outdoors, hiding in shady, damp places like mulch beds or piles of leaves. But when their usual prey becomes scarce or begins creeping toward your house, centipedes follow. While they do help reduce populations of unwanted bugs, repeated sightings inside suggest that a pest infestation is keeping them there.

House centipedes hunt and eat a range of indoor pests, such as:

  • Ants
  • Bed bugs
  • Cockroaches
  • Crickets
  • Earwigs
  • Moths
  • Silverfish
  • Spiders
  • Termites
  • And many more

Humidity Keeps Them Comfortable

Like many of their arthropod relatives, house centipedes need moisture to stay alive. Outside, they gravitate toward damp mulch, rotting logs, and compost. Inside, they prefer rooms with lingering humidity, such as steamy bathrooms, damp basements, and laundry areas with poor ventilation. Lowering the moisture levels indoors can help make your home less appealing.

Here are a few ways to tackle excess dampness:

  • Fix any outdoor leaks or dripping hoses
  • Clean gutters and make sure downspouts guide water away from the structure
  • Trim thick plants to help the soil dry faster
  • Use dehumidifiers in crawl spaces or basements
  • Ventilate bathrooms and laundry areas to improve airflow

Clutter Creates Hiding Spots for Centipedes

Dark, quiet spaces make perfect hiding spots for these fast-moving pests. Outdoors, they prefer to shelter under yard debris or in messy storage sheds. Inside, cluttered corners and unused items can give them a hiding spot to rest until nightfall.

You can eliminate their hiding places by:

  • Stacking firewood neatly and lifting it off the ground
  • Storing outdoor tools and pots in closed sheds or containers
  • Bringing patio items indoors when not in use
  • Clearing leaf piles and other plant matter regularly
  • Keeping your yard trimmed and your lawn mowed
  • Sealing cracks around windows, doors, and along the home’s base
  • Repairing screens and replacing old or damaged weather stripping

House Centipedes Start Their Journey Outside

You may have seen one racing across your bathroom or disappearing into a drain, but house centipedes don’t originate indoors. These fast-legged arthropods typically begin life outside in damp, shaded environments that provide cover and plenty of bugs to hunt. You’ll often find them hiding beneath soggy leaf piles, decomposing wood, garden mulch, or tucked under landscaping stones and bricks.

One of their favorite spots is the damp soil around your home’s foundation. This zone tends to stay humid and cool, while offering a constant supply of insects. Once centipedes settle into this space, it only takes a stretch of dry weather or a spike in temperature to push them indoors.

To keep them from sneaking in, pay attention to these outdoor hotspots:

  • Garden beds and decorative plants: These areas often host aphids, mites, and other prey that attract centipedes.
  • Paved surfaces and landscaping features: Pavers and bricks create ideal hiding places for insects and, in turn, their predators.
  • Poorly sealed trash bins: Rotting waste draws bugs, which eventually bring hungry centipedes along with them.

A messy or waterlogged yard doesn’t just encourage insect activity, it invites the creatures that feed on them too.

Are House Centipedes a Cause for Concern?

Their sudden sprints and many legs may be unnerving, but house centipedes usually keep to themselves. They aren’t aggressive and will typically flee if spotted. Most of the time, they’re only indoors because they’re chasing a food source, not because they want to interact with people.

Still, it’s not a good idea to handle one. Although their venom is meant for insects, a startled centipede might pinch with its front legs. This bite is generally brief, comparable to a bee sting, but can be uncomfortable.

For individuals with allergies to insect venom, a centipede bite could lead to more serious symptoms such as swelling, dizziness, or difficulty breathing. In such cases, immediate medical attention is necessary.

While these creatures are usually harmless to people, it’s wise to keep children and pets from engaging with them.

How to Recognize a House Centipede

If you’ve seen a strange bug and aren’t sure what it was, a house centipede has some distinct features that can help you identify it:

  • Legs: Thin and delicate, their legs fan out like those of a spider, giving them a wispy appearance.
  • Quantity of legs: They have 15 pairs, which helps them move quickly, but doesn’t make them the biggest centipede species.
  • Speed: These pests are impressively fast, capable of covering more than a foot in just a couple of seconds.
  • Coloring: Their bodies are typically pale grayish-yellow with three dark lines running lengthwise down their back.
  • Antennae: Long and fine, used to sense their surroundings and navigate in the dark.
  • Behavior: Skittish and non-aggressive, they prefer escaping over confrontation.
  • Venom: Strong enough for their prey, but only causes minor discomfort in most human interactions.

One Centipede Might Point to a Bigger Pest Problem

Seeing a lone house centipede doesn’t mean your home is infested with them, but it can signal a deeper issue. These predators only stay where food is plentiful. So, if you’re seeing them regularly, it probably means other pests are already living in your walls, basement, or crawlspaces.

Killing one centipede won’t solve the root of the issue. To truly keep them away, you’ll need to address whatever is drawing them indoors.

That’s where Griffin Pest Solutions can help. Our experienced team will inspect your property, identify signs of pest activity, and develop a tailored plan to eliminate both house centipedes and the bugs they’re preying on.

Beetles in Michigan

Michigan is home to 100s of varieties of beetles. Most of them are harmless, some are invasive, and many can be a nuisance. Beetle larvae – or grubs – are voracious eaters that destroy plants and lawns at the root. Wood burrowing larvae can damage and kill trees.

A beetle is an insect with six legs, a head, an abdomen and a thorax. What distinguishes beetles are two sets of wings – a hard protective outer pair called elytra and a soft inner pair. We cover some of the more popular beetles in Michigan and answer where beetles come from, whether they’re harmful and how to keep them away.

Stag Beetles

Stag beetles in Michigan are easily identified by the large pinchers or mandibles on the male members of the species. Theses mandibles are used in battles over food and mates. Despite their imposing appearance, stag beetles aren’t normally aggressive towards humans.

Stag beetle larvae

Stags are a black beetle with long shiny bodies. The females are smaller than the males. Stag beetle larvae are smooth white grubs with orange heads and legs. The larvae spend 3-5 years underground before becoming adults. Adult beetles hatch in early summer and usually die by September.

Stag beetles live in forests and wooded areas. Stag beetle larvae feed on dead and decaying wood. Adult stag beetles can’t eat solid food beyond tree sap and soft fruit and rely on built up fat reserves from when they were larvae. These beetles are a vital part of woodland habitats for their role in consuming dead and decaying trees.

Carpet Beetles

Carpet beetles are small oval shaped beetles with dark brown, orange and black mottling. They are named for their penchant for eating carpet as well as other textiles like wool, leather, felt and feathers. The larvae are the actual destructors; adult carpet beetles only eat flower pollen,

Carpet beetle larvae are small grubs covered in long orange hair. These small worms have a big appetite and leave behind shed skins and fabric holes as they grow.

Carpet beetles are sometimes confused with bed bugs. Both are small and prefer quiet areas like bedrooms, but carpet beetles don’t bite humans. Bed bugs lack wings and are usually a flat tan or brown color without mottling.

The best way to prevent carpet beetles is by vacuuming. Adult beetles will lay eggs in your carpet or in quiet corners. Vacuuming regularly usually catches the tiny eggs that you would never notice otherwise. If you encounter a carpet beetle infestation and see damaged textiles, Griffin Pest Solutions’ highly trained specialists can help.

June Bugs

June bugs encompass a variety of beetles that relate back to the Egyptian scarab. These large beetles in Michigan are popular around decks and patio lights. No one knows for certain why June bugs are so attracted to light.

June bugs or June beetles get their name from the time of year they normally appear. Like stag beetles, June bugs spend several years as grubs before they become adults. As the ground thaws after winter, the grubs pupate into their adult form and emerge as the shiny beetles you see around your home.

June bugs are mostly harmless. They aren’t aggressive and don’t bite humans. The main issue is with the larvae. June beetle grubs eat plant roots and grass while underground. If you have a grub infestation, it could cause brown patches in your lawn or garden.

Invasive Beetles in Michigan

Michigan has two invasive beetle species : the Asian long-horned beetle and the Japanese beetle.

  • Asian long-horned beetles are large black beetles with speckled markings and long antennae. Their larvae live in tress and create feeding tunnels. Eventually these tunnels can cause branches to break or even kill the infested tree. The best method for dealing with Asian long horns is, unfortunately, to remove the affected trees.

  • Japanese Beetles are shiny green metallic beetles with white hairs on their abdomen. These insects feed on flowers, fruits, vegetables, beans and corn. They can strip plants of their leaves and damage crops. The grubs can damage lawn and turf via underground roots. You can use pesticides as well as several natural methods to get rid of Japanese beetles in your garden.

Michigan’s Strangest Beetle

The blister beetle may be the oddest beetle we have in Michigan. While these garden dwellers help by reducing the grasshopper population, they also drip a toxic yellow ooze. This irritant is toxic to humans and will cause skin to blister.

Blister beetles are long and narrow with a slim neck. Their soft bodies range in color from black to gray with yellow or red stripes. If you come in contact with a blister beetle, you may not react right away. Welts typically appear 24-48 hours after contact. They are mostly harmless but can cause a painful burning sensation. To treat beetle blisters, keep the affected areas clean and use a topical steroid if needed.

Do Cockroaches Bite?

A cockroach on an apple with a bite out of it in Michigan.

There are cockroaches in Michigan. If you’ve spotted one in your home or your workplace – or anywhere – you probably have one pressing question above all others: Do cockroaches bite?

Yes, cockroaches in Michigan do bite!

And it’s gross and horrible like you’d expect. But they don’t bite often or in the way you’d expect.

The fact is cockroaches rarely bite humans. You’re much more likely to be stung by a bee or bit by a spider than a cockroach. That doesn’t make getting cockroaches out of your home or office any less urgent. It just means you won’t have red cockroach bite marks on your skin in addition to the constant fear of a small brown oval scuttling across your kitchen floor. We present the sometimes disturbing answers to your questions about nature’s perfect survivor – the cockroach.

What Do Cockroaches Eat?

Cockroaches are omnivores in the truest sense of the word. They eat nearly anything from fruits to rancid meat to book bindings and wallpaper. They are scavengers and opportunists who will raid any food supply they can get their grubby mandibles on.

With so little discretion for what they ingest, cockroaches rarely bother with potentially dangerous food sources such as humans. Why risk biting you when they can simply dive through your garbage? The fact that they can survive a month or more without food also means there’s no need for them to panic if they go a day or two without dinner leftovers.

Why Do Cockroaches Bite?

Most documented cockroach bite cases (and there aren’t that many) involve a large infestation of cockroaches with little to eat. Early accounts of this come from sailors on long sea voyages where they had to wear gloves and protective gear to fend off hungry roaches trying to get at their fingernails and eyelashes.

Other occurrences of cockroaches biting humans usually happen at night while the person is asleep. Cockroaches are nocturnal creatures that prefer quiet. If no other food sources are available, they may scavenge over your hands and face for traces of whatever you last ate. Even in these cases, the roaches are likely more interested in the food particles under your fingernails than your flesh. More terrifying than being bitten is the possibility of waking up to roaches using your face as a drive-thru window.

What Does A Cockroach Bite Look Like?

Cockroach bites don’t look much different than other insect bites. They appear as raised red dots along your skin. They are slightly bigger than bed bug bites and may itch in the same way. A tell-tale difference is that bed bug bites appear in clusters; cockroach bites will usually appear independently.

Cockroaches don’t transmit disease through their bites, but you do want to keep them clean. Like any animal or insect bite, if a cockroach bite becomes infected, it could become a health risk.

Do Cockroaches Carry Disease?

Roaches don’t carry specific diseases like a tick might carry Lyme disease. Instead, they are a health risk due to their behavior. Roaches often eat feces or rancid food found in sewers and dumpsters. They pick up harmful bacteria and germs and then spread them wherever they go.

If cockroaches contaminate your food with germs they’ve picked up, it could result in diarrhea, dysentery, cholera and other maladies. All the more incentive to keep a clean kitchen with food safely stored from prying insects.

Do Cockroaches Fly?

The bad news is cockroaches do fly. The good news is that they usually don’t like to. It seems that, despite having large prominent wings, most cockroaches are clumsy fliers and prefer to crawl. Makes sense when you realize that on land cockroaches are quite fast. They can run over 3 miles/hour. That’s equivalent to 100 miles/hour for a human when you account for size!

Some species of cockroach are more adept at flying than others. In warmer weather (over 85º) flying cockroaches will use their wings to glide as a means of conserving energy. They might glide down to your countertop if you left a midnight snack out for them.

What Do Baby Cockroaches Look Like?

Some cockroaches can get quite large and you may wonder if you’ve seen a baby or a full-grown adult.

A baby cockroach nymph

Baby cockroaches, also called nymphs, look like their adult counterparts. The three main differences between an adult and a nymph cockroach are:

  • Baby roaches are smaller in size (measuring about ¼ inch)
  • Roach nymphs are darker in color than adult cockroaches
  • Baby cockroaches don’t have wings yet. 

As cockroach nymphs grow, they go through several stages of molting. During each stage, they shed their exoskeleton in favor of a new, larger, one. Roach babies start out dark in color and become more reddish brown with each molt. They will eventually grow wings by adulthood.

Other Cockroach Facts

  • Cockroaches can live without their head for up to a week.
  • Female cockroaches lay their eggs in ootheca or egg sacs which can hold around 40 eggs.
  • Cockroaches have been around since the dinosaurs.
  • Cockroaches die on their backs because their thin legs can no longer support their heavy body mass.
  • Some cultures boil cockroaches and use the tea for medicinal purposes.

You Don’t Want Cockroaches in Your Michigan Home

Roaches may be fascinating but that doesn’t mean you want them in your home or business. If you’ve spotted a roach, it usually means there are others nearby. While they may not bite, they can cause health problems. Contact Griffin Pest Solutions for fast help when cockroaches show up hungry at your door.

Pest Control in the time of the Coronavirus

Where do rats live; Griffin Pest Solutions

The coronavirus changed just about everything very quickly, and Griffin’s pest control is no exception. In order to keep our employees and clients safe, we’ve had to carefully re-assess how we conduct our treatments. These are the measures we’ve adopted to prevent the spread of the coronavirus while we continue to tackle Michigan’s pest problems:

Coordinating from Home

As of the shelter in place order, all of our in-person team meetings have been indefinitely suspended. All personnel who can work from home are doing so, including the technicians who come to your home. Any technician who comes to your home is responsibly social distancing whenever they aren’t on the job.

When you call or contact Griffin for pest control help, our call center team receives the call from home. We coordinate to ensure we send a single nearby technician in a clean, disinfected truck. After the treatment, you will have the option to sign contracts, pay, and receive follow-up information electronically. We can coordinate the whole process effectively without putting our employees–or you–at risk.

On-site social distancing

Our commitment to responsible social distancing extends to our conduct on the job, as well. All technicians will wear extra protective clothing, including CDC-approved face masks and gloves, at all times. We avoid coming within six feet of you whenever possible. You can even ask us to call when we arrive and conduct our service without meeting you in person.

Whenever a technician has to touch something on your property, we will disinfect it immediately when we’re finished. We’ve also issued all technicians hand sanitizer, which they will apply before, during, and after treatments. Thanks to these precautions and treatment streamlining, we may never need to approach you while conducting service.

Outdoor-only Treatment

Griffin has altered our pest control treatments to emphasize outdoor-only treatment whenever possible. More details for what this means for your particular treatments are available on our service pages. Don’t worry: we’re still administering the same holistic, integrated pest control process we’ve proven so effective. We’re just only administering it to the areas outside your home or business.

For most pests, conducting exterior-only pest control actually won’t affect the efficacy of the treatment in the slightest. We can still find and seal off access points, eliminate attractants, and introduce effective repellents, baits, traps, and other methods of controlling and preventing pest access. If we ever determine that we do need to enter your property in order to provide effective pest control, we’ll explain why and ask permission first. Technicians will take your safety very seriously when we’re inside your home or business.

On-site Disinfection and service

Griffin hasn’t just altered our existing services in response to the coronavirus; we’ve actually developed some new ones, too. Griffin’s new DSV Disinfection and Sanitation service was developed in order to help protect our clients from the coronavirus. During this service, our technicians will use an EPA-approved Disinfect, Sanitize, Virucide solution to effectively kill the COVID-19-causing virus on all at-risk surfaces.

DSV Disinfection and Sanitation works as either a means of treating known infected areas or an effective precautionary measure. Technicians administer the DSV solution very carefully, while maintaining social distancing and wearing appropriate safety gear. Even if you don’t opt for the DSV treatment, Griffin’s technicians will still disinfect areas of your property we come into contact with during other treatments.

 

Griffin Pest Solutions is taking the coronavirus and shelter in place order very seriously. Your health and safety is our top priority. If you have a pest problem, we want you to know you can call on us for help without anxiety–no ifs, ants, or bugs! We’re doing whatever we can to make sure that’s the case.

If you have more questions about our temporary exterior-only approach to pest control, our new DSV service, or how we’re committed to keeping you safe during our pest treatments, please call or contact us right away. We’re always ready to help–and from a safe distance.

Why Are There Crawling Insects in My House?

Unless uninvited guests arrive carrying a free cake or a large check, you’re probably not a fan. When uninvited visitors have six or more legs and creep across your floor, they’re even less welcome. Nobody wants crawling insects to infest their homes, but how do you keep them out? What causes them in the first place? Why won’t they leave you alone?

First: you keep them from happening by taking preventative measures. Second: the things that cause them are usually easily fixed. Third: they won’t leave you alone because there’s something at your home drawing them in. Today we’ll cover the four most common crawling insect invaders people face. We’ll also arm you with the easy fixes and preventative measures you can take to keep them away.

Ants 

Ants are one of the most commonly-faced crawling pest problems for both home and business owners. There are over seven hundred different known species in the United States. Of those, there are a few ant varieties that are best known for infesting homes. Those include carpenter ants, pavement ants, odorous house ants, and field ants. Ants typically live in large colonies that work together to build and maintain their nests.

How can I keep ants out of my home?

  • Practice regular perimeter maintenance. Ants like to sneak in through small breaches or holes in your home’s perimeter. Make sure to regularly give your home visual inspections and seal any gaps, cracks, tears, or holes you find as you go. 
  • Keep a watch out for scouts. Single ants are scouts. They come up from their nests to look for food, water, or shelter. Get rid of any solo ants you find so they’re unable to share that information with the rest of their colony.

Centipedes

Despite their name’s disturbing implication that centipedes have one hundred legs, the crawling pests usually don’t. Instead, they have one pair of legs per body segment and can have, on average, between fifteen and seventy total pairs. There are many varieties but they all have flat, elongated bodies. They can measure from one-sixth of an inch to six and a half inches in length. Coloring varies but usually stays between shades of brown, red, and orange.

How can I keep centipedes out of my home?

  • Eliminate their food sources. Centipedes mainly consume other insects. If you’re practicing the rest of the prevention tips listed in this post to keep other pests away, you’re doing well. 
  • Reduce and remove clutter. A tidy home is a home that doesn’t have places for insects to hide. That includes but isn’t limited to centipedes.

Cockroaches 

Everybody knows about roaches. They’re one of the hardiest creatures on the planet, able to survive in temperatures at both spectrum extremes. The most common pest cockroaches are the German cockroach and the American cockroach. German cockroaches are brownish-black, measuring between ½ and ⅝ inches. American roaches are darker in color and large, measuring between one and two inches. They’re both active throughout the year, are nocturnal, and are drawn to decaying organic matter.

How can I keep roaches out of my home?

  • Wipe up crumbs and spills as soon as you make them. Cockroaches love organic matter. They especially love decaying organic matter. Don’t leave it out for them to find. Wipe up spills and crumbs as soon as they happen and don’t leave dirty dishes in the sink. 
  • Pay special attention to cleanliness. This tip is mentioned more than once, but that’s because it’s important. Insects like cockroaches thrive in unkempt spaces. Take the garbage out regularly, remove grease from the stovetop, and keep your floors clean. These small efforts will go a long way toward preventing roach infestations.

Earwigs

Let’s start out by dispelling a popular earwig myth. No, they won’t actually crawl into your ear while you’re asleep and eat your brain. They won’t even crawl into your ear and take a nap, leaving your brain alone. They won’t go inside your head. What they will do, however, is infest your home. Earwigs are typically a quarter-inch to one inch in length with elongated, flat bodies. Their color can vary between different shades of tan, brown, and red. Their most distinctive physical characteristic are the pincers located on the back of their abdomens.

How can I keep earwigs out of my home?

  • Eliminate the places they like to hide. Earwigs love dead and distressed outdoor spaces. They hide in these spaces and use them as jumping off points for interior infestations. Take away their hiding spots by removing leaf piles, overgrown vegetation, and untended woodpiles. 
  • Make sure your gutters are working properly. Moisture build-up from gutters that are clogged pointing in the wrong direction will draw in earwigs. 
  • Use dehumidifiers. Once more with feeling: earwigs love moisture. Make sure you’re policing the moisture in your home and removing any standing water as you notice it.

If your question is, “Why are there crawling insects in my house?,” the answer is, “Because you’re not keeping them out.” Luckily, with the help of this blog post and other useful tips and tricks, you’ll be able to turn things around. For the rest, you can call the team at Griffin Pest Solutions. We’ll help keep your home safe, secure, and crawling pest free.

What are House Centipedes?

House centipede running across hardwood floor in someone's home

House centipedes (Scutigera coleoptrata) are rather unique centipedes. For one thing, they don’t really look like what you picture when you think of a centipede. They look… creepier. More importantly, unlike almost all other centipedes, they can live in your house (hence the name). If you see a centipede in your house, it’s almost certainly a house centipede.

Like most pests, the scariest things about these centipedes are the things you don’t know. If you don’t know what you’re looking at, they look like your worst nightmare. They’re all legs, fangs, and antennae, and they’re fast. Learning about centipedes probably won’t mean you’re not afraid of them at all, but it’ll certainly help. At the very least, you’ll know what that freaky thing you saw darting around your bathroom was. 

Take away a house centipede’s sources of food, shelter, and moisture, and you’ll take away their reason for entering your home. If you want some help removing centipedes from your home, get in touch with Griffin Pest Solutions. We’re always ready to help remove creepy crawlies and keep them from getting in again. Never worry about house centipedes again; just give us a call instead!
