Fall Pests That Can Live in Your Walls

As the weather gets colder, you may start to notice an increase in insects and other unwelcome creatures in your home. This is a process called overwintering, which is when pests try to escape the increasingly cold weather, and it happens like clockwork every fall. Some species migrate to warmer climates, some burrow in or under debris, while others just try to get into our homes to warm up. It’s easy to avoid in most cases, but once they cross the threshold into your living space it becomes a big problem.

There are several types of pests known for trying to get in. The most difficult pests to get rid of, however, are the ones that make their way into the attic or behind your walls. These are the hidden dangers that you often don’t notice until they’ve caused real damage. This can include Asian lady beetles, rodents, termites, stink bugs, and wasps. Read on to learn more about these common pests that invade homes in the fall.

Asian Lady Beetles

White Asian Lady beetle are a little larger than ladybugs and share the same general shape and coloration. They look harmless at first glance, so what’s the problem? White Asian Ladies stick together in groups and use pheromones to communicate their location. So, if one or two get into your home, it can very easily balloon into a huge infestation. The good news is that these bugs aren’t known for stinging, biting, or destroying the household. Still, their presence could trigger respiratory issues in sensitive people. Because of this, it’s best, like with any insect infestation, to make sure the cracks and crevices of your home’s exterior are thoroughly sealed.


Squirrels, roof rats, and mice are all known for their excellent climbing capabilities, and the odds are good that you’ve seen one of them scurrying across a fence or through some trees. With skills like theirs, they can easily get into your attic and make a nice and cozy nest to wait out the cold. Have you been hearing any scratching or gnawing noises from inside your walls? If so, you likely have a rodent inside your attic or wall voids. That means that it’s time to call an experienced rodent exterminator like Johnson Pest Control

Stink Bugs

How do you catch a stink bug before things get smelly? The Brown Marmorated stink bug, an invasive species straight from the East, is the most common variety to find in the quiet parts of your house. They’re shaped like a shield, range in size from ¼” to ⅜, and colored in shades of brown and gray. When the cold season rolls around, they tend to stick to undisturbed spots in the home like the attic, crawlspace, or space between walls. Handling them can be tricky to do on your own, as if they feel that their lives are in danger they are known for releasing a titular smell that’s undeniable and definitely unpleasant.


Termites are the nightmare of any homeowner in America, with the estimated annual cost of damage done ranging up to $30 billion. These microscopic menaces always want to get inside your house. However, the most destructive species of termites are the subterranean termite, and they’re capable of burrowing deeper in the ground in the fall and winter and causing damage you won’t notice till spring.  Termites in the home are focused entirely on consuming anything with cellulose. If you’ve noticed things such as blisters on painted, hollow-sounding wood and unexplained pinhole-sized holes, that means you’re in desperate need of service from one of our qualified exterminators. 


Most of the average wasp colonies don’t overwinter, which means that a majority of the population dies as the weather gets colder. However, fertilized queens are able to overwinter outdoors in hollow logs, stumps, under leaves or in structures such as the attics of homes. The most common way for wasps to get in is through attic vents that aren’t screened. So like with the stink bug and other pests and vermin, this can be prevented by making sure your attic is properly sealed from the elements.

Rodent Awareness Week 2020: The Surge in Rodents

Rodent infestations rise during the pandemic in Sevierville TN - Johnson Pest Control

Have you noticed more rodents this year than ever? There are a few reasons behind this. First, rodents are typically more active this time of year as the weather shifts. This drives many into properties and homes in search of warmth. However, you may be seeing them more now than ever due to the pandemic. Restaurant closures or restrictions in the past year has depleted the normal food source for rats. This has led not only to an increase of infestations, but also an increase in their aggressive behavior! More competition for food means that rodents are more compelled than ever to get inside your home here in Tennessee. This Rodent Awareness Week, the team at Johnson wants to share their best tips to protect you and your family from rats this year.

Are Rodents More Dangerous During the Pandemic?

While rodents may be more common right now, there’s no reason to worry about them spreading COVID-19. As of now, there is no evidence to show that rodents are transmitting SARS-CoV-2 to humans. The main concern with rats and mice currently is that they are getting more aggressive in nature, can carry other diseases, and could cause damage to your property.

The shelter in place shutdowns caused an uptick in residential rodent sightings as rats and mice became bolder in their hunt for resources. This has since caused an uptick in infestations and rodent-spread issues. While they won’t transmit COVID-19 to you or your family, rodents still can spread other diseases including hantavirus, salmonellosis, and many more. They also can cause significant damage.

Tips to Keep Rodents Out

Rodent exclusion is the best way to ensure you stay safe from rodents. Our top tips to prevent rodents this year include:

  1. Securely store all food in metal or glass containers with tight-fitting lids.
  2. Clean inside the house and around the garden. Less clutter means fewer places to hide.
  3. Put outdoor garbage bags in metal garbage cans with securely fitted lids to stop them from feeding on contents.
  4. Seal off cracks and crevices around openings. Mice can squeeze inside holes the size of a dime.
  5. Clean up pet food and bird seed debris, and store pet food in robust containers with fitted lids, preferably above ground level.
  6. If you have a compost heap don’t include organic food waste, as this will attract them.
  7. Inspect your garage, attic, crawlspaces, and vents for potential rodent hiding spots.

Why is Rodent Awareness Week Important?

Here at Johnson, we make sure to inform our customers every Rodent Awareness Week about the dangers of rats and mice. This year is especially important with the ongoing rise in infestations. If you need assistance sealing off your home to these pests, our rodent exterminators can help. Contact us today to learn more!

Asian Lady Beetles in the Fall

Asian lady beetles get inside Sevierville TN homes in the fall - Johnson Pest ControlAsian ladybugs are commonly mistaken for ladybugs, but these two insects are different! The Asian lady beetle is considered to be a common pest here in Sevierville in the fall. This is because the insects will congregate outside properties on warm sunny afternoons. From there, they have been known to make their way into your home as well as make themselves at home once indoors! They may be found in attics, wall voids, on siding, and are attracted to light. These beetles normally enter homes on the southern and western exposures (sunny side) of structures. The team at Russell’s Pest Control is here to help shed some light on this common autumn pest problem—keep reading to learn more!

What Do Asian Lady Beetles Look Like?

Asian lady beetles are usually confused for normal ladybugs. However, they are slightly larger than native species. The coloration of this beetle varies from mustard-yellow to a dark reddish-orange. The key identifying marks on this beetle are two white, oval markings on the pronotum (just behind its head) along with an occasional M-shaped marking on the pronotum. The biggest difference between Asian lady beetles and ladybugs is their behavior as the beetles look to enter homes in the fall.

How to Prevent a Fall Asian Lady Beetle Infestation

Before the first frost, adult Asian lady beetles begin to seek shelter to spend the winter. This is why fall infestations are so common as they flock to the sides of your home in the sun. To prevent the insects from getting inside, try out the following tips:

  • Seal cracks around windows, doors, utility pipes, siding, behind chimneys, and around any other openings.
  • Repair or replace damaged screens on doors and windows.
  • Replace the weather stripping around windows and doors.
  • Consider planting mums in your garden or around your home. These beetles are not fans of the plants and will avoid them at all costs.
  • Another all-natural deterrent is citrus or citronella scents. Make a spray with orange or lemon essential oil diluted with water, and spray around your windows or doors.

Asian Lady Beetle Infestations

If Asian lady beetles have already entered your home, use a vacuum cleaner to vacuum them up, and dispose of them in a sealed plastic bag. These bugs are capable of biting, but their bite is typically harmless. Like other bugs, they will release an odorous scent when crushed, and their stains can discolor items in your home.

How to Prevent the Bugs on the Side of Your Home

Stink bugs are a common fall invader to Sevierville TN homes in the fall - Johnson Pest ControlDo you notice the same bugs congregating on the side of your Sevierville area home every fall season? You may have a boxelder bug or stink bug problem! Both of these insects are known for a couple of things. One, the foul odor they release when crushed or threatened. And two, their odd behavior of aggregating on the sides of buildings and structures in the fall months. Their populations can grow to large numbers, making the very sight of them worrisome. However, the real trouble is when boxelder bugs or stink bugs crawl their way into your home. While not particularly dangerous, they are a downright nuisance and difficult to get rid of.

Boxelder Bugs vs. Stink Bugs

Both these insects will crawl their way through any crack and crevice in your home’s exterior to gain access to the warmth of your home before the winter months. Even worse, they reproduce at a rapid rate. Here’s how to identify the bugs on the side of your home:

    1. Boxelder bug
      • These insects have dark brown bodies with unique red markings.
      • They emerge out of hibernation in the springtime.
      • True to their name, they live in boxelder trees as well as maple, ash, and fruit trees.
      • Their feces can leave a stain.
    2. Stink bug
      • Their backs look like shields, and they can blend easily within foliage.
      • If threatened, these bugs release an odor.
      • There are two main types we see in the states: the brown marmorated stink bug and the green stink bug.
      • They do not bite or spread disease.

  3. Seal any cracks and crevices. Inspect the inside and outside of your property for tiny spots that may be inviting spiders in, and seal properly.
  4. Install or repair screens on doors and windows. Holes or crevices in screens will easily invite spiders (and other pests) inside.
  5. Inspect boxes and used furniture prior to bringing them inside. Adult spiders or egg sacs could be nestled in old unopened boxes.
