Fall Pests That Want in Your Home

If it seems like there’s an increase in insects in and around your home in the fall, you’re probably right. It’s the result of pests trying to get indoors as the weather gets colder. Some pests migrate to warmer climates, some burrow in or under debris, while others just try to get into our homes to warm up. The scientific term for this phenomenon is overwintering. Pests will find a suitable area to settle in during the colder months and then become more active in the spring. 

This most directly affects you when fall pests enter your home. Some do this by coming in through small openings that are already present and others will chew their way in. There are several types of pests known to try to get in, from insects to rodents. The most difficult fall pests to get rid of are the ones you can’t see because they get in the attic or behind your walls. Read on to learn more about the common pests that may try to get in your home in the fall. 

Rodents

You probably know that squirrels are excellent climbers but did you know that roof rats and mice can also climb well? Most rodents will climb almost anything; branches, fences and drainpipes can all be used to access the roof of your home!  From there, it’s easy to get into your attic and make a nest to stay warm for the fall and winter. If you hear scratching or gnawing noises from up above or inside the walls, you likely have rodents inside your attic or wall voids starting to make themselves at home. Should this happen, it would be time to call an experienced rodent exterminator like the specialists at Griffin Pest Solutions. It is also advised that you ensure your home is properly sealed to help prevent rodent entry. A mouse can enter an opening roughly the size of a dime! Squirrels will chew on dormers and fascia boards to make their own entry points. 

Asian lady beetles

While Asian lady beetles resemble ladybugs, they’re somewhat larger. Their coloration ranges from red to orange and not all of them have spots. So, what’s the problem with these small ladybug look-alikes? They hang out together in large groups, using pheromones to communicate their location. When they decide to enter your home to get warm, the result can be a large infestation that ends up in your attic or walls. While they won’t directly cause harm by damaging your home or stinging you, there are unpleasant side effects. Should you end up with an infestation, lady beetle waste can stain and is known for triggering allergic reactions or breathing difficulties in sensitive individuals.

The best way to prevent these, or any bugs, from getting into your home is to seal cracks and crevices on the exterior of your home. Asian lady beetles are small, so you’ll need to be diligent should you choose to take on this task. Having a preventative pest control service in place can also help to prevent a pest infestation from taking place in your home. If a product is applied to your home consistently, it doesn’t allow for an infestation to even begin. 

Stink bugs

While there are several types of stink bugs, the brown marmorated stink bug is the one you’re most likely to see in your home. It’s an invasive species originally from Asia. They’re shaped like a shield and their color is a mottled combination of brown and gray. They range in size from ¼” to ⅜”. As their name suggests, when stink bugs feel threatened or get squashed, they release an unpleasant odor. Stink bugs tend to spend the winter in quiet parts of a home where they’re unlikely to be disturbed like an attic, crawlspace or inside the walls. 

When you see these pests walking on your home or nearby trees, it is easy to forget that they can fly and it’s their wings that bring them to your home in swarms at times. You will first start to notice these fall pests as the temperature starts to cool at night but the days are still warm. Stink bugs will land on the sides of your home, where the sun is warming the siding, this helps them to stay warm as well. They are drawn to lighter-colored homes, which can be the reason you are seeing them but your neighbor doesn’t have any issues.

Wasps

A whole wasp colony doesn’t overwinter, just the queens. The worker wasps won’t survive the winter and the queen will start a new colony every year.  The fertilized queens overwinter outdoors in places such as hollow logs, stumps or under leaves. However, they can also overwinter on or in structures, including the attics or siding of homes. The most common way for wasps to get in is through attic vents that aren’t screened. If you haven’t done so lately, look for openings into your attic and seal them as much as possible to help prevent wasps and other pests from entering. It is possible for the queen to start her new colony in your attic, which can mean a large nest of wasps could end up inside!

Why Do I Have Stink Bugs This Winter?

Stink bug during winter

Stink bugs typically enter a state of dormancy called diapause in winter. Unless, of course, they can find a heat source to sustain them. If they do find a heat source–say your home–they can remain active all year. Any stink bugs in your home will seek hiding places to wait out the winter. They’ll almost leave you alone… but the smell might not.

Obviously, nobody wants stink bugs in their house in winter, but how do you get rid of stink bugs? Especially if you have an infestation? And what draws them to some buildings over others? Here’s how you can find (and remove) stink bugs in your home this winter:

Signs of Stink Bugs in Winter

To tell if you have a stink bug infestation, look for these signs that they may be nearby:

  • Live bugs. Stink bugs’ bodies are brown or black and shaped like a shield. They have spots of lighter coloring around the edge of their body, six legs, and antenna. If you see one, then there are almost certainly more nearby. If you see one moving around inside your home, then you probably have an infestation. 
  • Dead bugs. Pay attention to the entry points in your home, including door frames, windows, and baseboards. Stink bugs congregate around heat sources, especially in fall and winter. When they find cracks and gaps around these heat sources, they push and squeeze their way through. Sometimes, not all the bugs will make it all the way through. You might find the bodies of less-fortunate members of the party around door and window frames, baseboards, and utility lines.
  • Stink. Stink bugs… got their name for a reason. When they feel threatened, these bugs secrete a foul-smelling liquid in defense. If you smell a pungent odor like rotten vegetables or cilantro, it may be a stink bug. Stink bug liquid secretions are a pale-yellow color and can stain surfaces over time. They also use this scent to attract others when to sources of food and shelter.

Why my home?

Stink bugs come into homes looking for shelter, water, and food. Their preferred food source is sugar and they’re fond of overripe fruit. They’ll also congregate around the food waste in trash cans or beneath cupboards and the dishwasher. 

Sugar isn’t the only stink bug draw. They also gather around light and other heat sources. They’ll be particularly noticeable at night, when you’ll see them scurrying around outdoor light bulbs or indoor lamps. Food or heat sources could be reasons why you have a stink bug problem.

How to Prevent Stink Bugs

Keep stink bugs from bothering your property by taking some of the following steps: 

Keep stink bugs from bothering your property by taking some of the following steps: 

  • Minimize outdoor lighting. Don’t keep any outdoor lighting on unless it’s necessary. The more bugs your lights draw to the surface of your home, the higher the odds that at least some of the congregation will find its way inside.
  • Rub your window screens with dryer sheets. This sounds weird, but it’s an easy prevention tactic. The fragrance of your average scented dryer sheet is unpleasant to a stink bug. Rub them on your window screens when doing regular cleaning as a simple exclusion effort. 
  • Fix plumbing leaks. Stink bugs are drawn to moisture they can access without drawing attention to themselves. This is most easily found near hidden plumbing leaks in faucets and pipe joints and under counters and cabinets.

How to Get Rid of Stink Bugs

Stink bugs will usually naturally leave your home in spring when they re-emerge from dormancy. We recommend leaving the cracks and crevices where they might enter diapause in your home alone until then. If you seal up their hiding places, stink bugs will die inside your home. When stink bugs die, they secrete their odor–which contains a pheromone that attracts more stink bugs. They also secrete this odor when you crush them or when they find good hiding places.

If you notice active stink bugs inside, vacuum them up (don’t crush them!). Dispose of the vacuum bag outside of your home. Whenever you remove bugs from a surface, clean that surface with ammonia and/or soapy water. This will help remove pheromone secretions and keep more the bugs away. Focus on exclusion methods until you’re sure all the stink bugs are gone. If you trap or kill too many of the bugs, it’ll only exacerbate your problem.

Intercepting Stink Bugs in the Wintertime

Intercepting Stink Bugs

Unlike many other pests in our part of the world, stink bugs don’t infest homes during the spring or summer. Instead, Michigan’s newest neighbor tends to start infesting homes in late fall and early winter. If you see a stink bug in your home come early spring, it’s probably because it spent winter with you.

We know that’s not exactly great news. Stink bugs survive winter by getting cozy in shelter and basically going dormant until spring comes. But, as we keep our homes nice and warm, it’s not uncommon to see a few stink bugs in your home during the winter. If you don’t want to run into them in a few months, you should consider intercepting them now. Here’s everything you need to know to do it.

How They Survive

How stink bugs survive winterWhen temperatures drop, stink bugs enter a special hibernation-like state called diapause. Diapause dramatically slows down the stink bug’s metabolism, allowing it to survive without food for long periods of time. Instead of feeding, stink bugs in diapause burn through nutrients they spent the spring and summer stockpiling. Basically, they fatten themselves up for winter just like squirrels.

Stink bugs have to enter diapause in winter because the fruits, seeds, and nuts they feed on aren’t available. It solves their food problem, but they’re on their own when it comes to the cold problem. Stink bugs are native to Southeast Asia, and never developed adaptations to help them survive cold. Even if they entered diapause outside, their bodies would freeze and they would die. Unfortunately, that’s where your home comes in. Stink bugs try to sneak into structures for one reason: to keep warm and sleep away the winter.

Where They Go

where stink bugs go in winterStink bugs enter buildings via the same access points most pests find. Usually, they crawl through cracks and crevices around door and window frames or utility lines. Stink bugs fly and climb surfaces, so they may use vents, chimneys, or roofing damage to get in, as well. It’s only after stink bugs infiltrate a home successfully that their behavior becomes a bit more unique.

When stink bugs enter diapause, they can’t move and only have a minimal awareness of their surroundings. They have to be very careful about where they enter diapause if they ever want to wake back up! Once inside, stink bugs shack up in the quietest, most inaccessible or forgotten part of your home. They might be in air vents, under appliances, behind walls or flooring, or even hiding inside furniture. You’ll probably never find stink bugs inside unless you go looking for them.

Are they a Problem?

are stink bugs a problem in winter?No. When stink bugs enter homes, it’s only ever to stay warm while they sleep away the winter. They don’t eat or infest your food, damage structural material, create nests, mate, or lay eggs. In fact, stink bugs won’t begin their mating season or lay eggs in spring until after they’ve left your home. Pretty considerate of them, really. The pests don’t transmit diseases or harm humans and pests in any other way, either.

That being said, there is the matter of their name. Stink bugs… stink. When threatened or startled, they secrete a foul-smelling liquid from a scent gland. The scent has been compared to cilantro or coriander. The secretion is mostly harmless, though it may trigger allergic reactions or stain fabrics in concentrated amounts. Stink bugs may also produce a pheromone that attracts other stink bugs to their location. A lot of stink bugs aren’t any more dangerous or destructive than a few, but they are stinkier.  

What To Do About Them

what to do about stink bugsFirst, vacuum up the stink bugs you find with a shop vac. Remove and dispose of the vacuum bag into an outdoor dumpster when you’re finished. Clean the surfaces where you find stink bugs with soapy water and a washcloth. Try not to crush stink bugs when you find them, because they’ll release their scent on death. Remember to check the secluded or hidden areas where stink bugs like to hide. Cleaning these areas regularly will make them far less attractive to the pest.

When you’ve removed all the stink bugs you can find, focus on locating where they got in. Look for cracks and crevices around baseboards, door and window frames, the foundation, or insulation. Seal up cracks with caulk to prevent additional bugs from following residual scent left behind by the first infestation. Stink bugs’ bodies are quite flat, so even small cracks provide them with enough room to sneak through.

 

Stink bugs aren’t the most disruptive of winter pests, but you shouldn’t have to share your home with them. Come spring, any stink bugs you don’t find now will make themselves apparent, often in upsetting ways. Luckily, by getting to know stink bugs and following these steps, you can ensure that doesn’t happen.
