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.
