What is an Earwig?

Earwig close-up

Earwigs are also known as “pincher bugs” for a pretty obvious reason: they have a big pair of pinchers on their butts! A lot of people also know them as “Agh!,” “What is that thing?!,” and “Oh no!” Earwigs are one of the most panic-provoking pests you can encounter in Michigan. Again: they have a big pair of pinchers on their butts!

Earwig’s pinchers, along with their ominous name, have given them quite a reputation. As a consequence, the bugs tend to be much-feared and little-understood. We want to change that. Not for them really, so much as for you and your heart rate. Here’s everything you need to know about the earwigs in your garden, including why they aren’t dangerous.

So: What is an Earwig?

Earwigs are insects of the order Dermaptera. The most common species in Michigan is the European earwig (Forficula auricularia). Adult European earwigs are ⅝” long, with elongated, flattened bodies that are reddish-brown. They have segmented abdomens, medium-length, segmented antennae, and chewing mouthparts. Their antennae, legs, head, pincers may look lighter than the rest of their bodies.

Earwig’s “pinchers” are called cerci. Male’s cerci curve and resemble forceps, while female cerci are straight. Adults also have fully-functional wings, which emerge from beneath short, hard wing covers on their backs. Adults can fly for short distances competently but rarely do.

Where Do Earwigs Come From?

European earwigs were first discovered in the US in Seattle (of all places!) in 1907. Since then, they’ve spread throughout most of the US. Earwigs have been established in Michigan since the 1930s. They’re attracted to wet, shady environments, so it makes sense they’d like Michigan.

Earwigs are nocturnal and spend days nestled in dark, moist environments. They’ll huddle under wet leaves, topsoil, rocks, logs, or other cracks or crevices. At night they’ll come out of these hiding places for forage and/or hunt for food nearby. They’re common in gardens, wooded areas, and compost piles.

What Do Earwigs Want?

European earwigs feed on wet, decaying vegetation, like compost and other decaying plant life. They’re attracted to food that’s near their living environment. Many target the root systems of garden plants, weeds, and flowers, feeding on these plants from under topsoil.

In winter and summer, it might get too cold or hot for the insects to survive. When that happens, they’ll seek out shelter. Ideal shelter keeps the bugs out of freezing temperatures but isn’t so hot that they dry out quickly. In other words, they’re looking for a warm, humid, dark, and hidden place. Which brings us to…

How do earwigs get inside homes?

How Do Earwigs Get Inside Homes?

When earwigs enter buildings, it’s usually by accident. Most enter buildings either in the middle of summer or early fall. Generally, they’re looking for shelter and they accidentally slip through a crack into a building. If earwigs enter your home, then they were probably already living nearby.

Earwigs often burrow under topsoil near your home or garden. They may find cracks and crevices in the foundation or baseboard to work their way into under the soil. Like many pests, they can also squeeze through gaps around window frames. Earwigs frequently find cracks around basement window wells, in particular.

Are Earwigs Dangerous?

No. Contrary to popular belief, earwigs do not burrow into people’s ears to lay eggs. The name actually refers to their wings, which are shaped like ears when unfolded. Earwigs are completely harmless. Even if they pinch you, they won’t be able to break the skin.

Outside, earwigs can inflict damage on garden plants. They’re known to feed on the bulbs, stems, and petals of flowers. In some extreme cases, they can actually substantially damage plants by feeding on them. They may also produce a foul-smelling odor when they’re crushed. The pests may be a nuisance, but they’re not dangerous.

How Do I Keep Earwigs Away?

Re-seal and weatherproof your basement’s window well frames. Look for cracks or gaps around your basement ceiling and seal them up. Check the baseboard and trim, too. Earwigs travel into homes by finding and wiggling through small cracks. You may also be able to find these openings outside.

It’s more difficult to keep the bugs away outside, but there are still a few steps you can take. Take good care of your garden and lawn. Clear up weeds frequently, trim regularly, and remove plants as soon as they die. Be careful not to overwater your plants.

 

Earwigs aren’t dangerous and don’t inflict major damage on homes. Hopefully, this will make them a bit less scary next time you find one. But… we’d understand if it didn’t. They have a big pair of pinchers on their butts!

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.
