Winter Invaders to Watch Out For

Mouse in snow

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

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

stink bugs

Stink Bugs

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

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

cluster flies

Cluster Flies

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

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

rodents

Rodents

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

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

boxelder bugs

Boxelder Bugs

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

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

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

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

4 Fall Projects for Keeping Boxelder Bugs Away

Swarm of boxelder bugs on wood

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.
