What Should You Do If You See an Atlas Moth?

In August 2022, reports of a giant Atlas Moth spotted near Seattle, Washington, made headlines because it was the first time this gargantuan species had been seen in the United States. It’s a beautiful species, the second largest moth in the world, but it’s also a big problem. That’s because the Atlas Moth is native to the boreal parts of southeast Asia and Borneo, about 7,500 miles away. They’re evolved for the forest ecosystems of that part of the world, not the forests of North America. So what should you do if you see an atlas moth here?

They shouldn’t be here, and they pose some very real threats here, like outcompeting native species and throwing ecosystems out of balance. That’s why the Atlas Moth has been classified by the United States Department of Fish and Wildlife as a “quarantine pest.” Essentially, that means it’s an invasive species. That’s why, if you see an Atlas Moth, the first thing you should do is marvel at it, and then it’s your duty to report it.

What Does the Atlas Moth Look Like?

Atlas Moths are awe-inspiringly large. If you see one, it will probably be the biggest moth you’ve ever seen. Its patterns and coloring look like the cecropia moth or polyphemus moth, both of which are native to the U.S., but those two species are significantly smaller.

The cecropia moth is the largest moth native to the U.S. Its wingspan can reach 7” – 8” long. An Atlas Moth, by comparison, can reach 10” or more. Polyphemus moths are much smaller than either: they’re usually about 3” – 4”. Polyphemus moths also have fuzzier bodies, and fuller wings.

How Did the Atlas Moth Get Here?

It’s an unfortunate dilemma because the Atlas Moth did not choose to come here. They’re not adapted to fly thousands of miles across the ocean. Sadly, it appears that a person smuggled them here for economic gain – there’s a thriving black market for insects. Shortly after the discovery of the specimen in Seattle, an eBay listing offering Atlas Moth cocoons for $60 each was found. However, the listing was quickly taken down and authorities have not been able to trace the seller.

It’s hard to know how many Atlas Moth cocoons were sold and shipped, but there could be many across the United States, which is why it’s important to know what it looks like – even if there hasn’t been a sighting in Bristol and Johnson City TN yet.

The Atlas Moth’s Potential Harm to Ecosystems

Anytime you introduce a new species into an ecosystem, there are unknown risks. Nature is a delicate balance, so removing one species can have a domino effect for years to come. It may not seem like a big deal, but one change can alter a natural area permanently.

We do know a few things about the Atlas Moth life cycle, and the ecosystems in southeast Asia they inhabit.

Atlas Moths are impressively large caterpillars before their metamorphosis. They ward off predators by spraying a foul smelling liquid. They’re voracious eaters, and spend every possible moment eating. (They have to – because adult Atlas Moths don’t eat at all, they survive only off the nutrients and fat stored when they were caterpillars). It’s because they’re such hungry caterpillars that lead to worries that Atlas Moth caterpillars may be able to outcompete cecropia and polyphemus moth caterpillars, and ultimately threaten their numbers.

What to Do If You Spot an Atlas Moth

Atlas Moths are not dangerous to humans. They won’t bite, and they’re not poisonous, yet they pose a significant threat to humans in their potential to harm ecosystems.

That’s why if you see one of these hard-to-miss Atlas Moths, we ask that you please notify the U.S. Department of Fish and Wildlife or your state’s office for plant and animal regulation.

Which Fall Pests Could Be Lurking in Your Walls?

Which Fall Pests Could Be Lurking in Your Walls?

Every year when temperatures drop, insects and vermin that don’t die off take part in a phenomenon called “overwintering,” which basically means they find a habitable environment to wait out the winter months. Some of these fall pests will migrate to warmer climates. Some find hiding spots outside under debris. The ones we’re most concerned about are those that make their way indoors into homes and buildings.

You should be aware of this possibility even if you don’t see them in places like your bedroom or bathroom. Fall pests love low-traffic areas like the space behind your walls or your attic. They can spend the entire season camping out there and come spring you may find that you’re dealing with a full-blown infestation.

Common Overwintering Pests in Tennessee

The most frequent fall pests we receive calls for here in Bristol and Johnson City TN include rodents, termites, stink bugs, Asian lady beetles, and wasps.


Vermin can get into your attic by climbing up onto the roof. Squirrels are the most well-known culprits, but roof rats and mice are just as notorious for invading homes and making nests in the attic. How can you tell if you have rodents living in your home? The most common sign of a rodent infestation is scratching or gnawing sounds from above or from inside the walls. If you hear these sounds, it’s time to call an expert rodent exterminator.


It’s no wonder that termites are considered the most destructive pest in the United States. The cost of termite damage in the is estimated to be up to $30 billion annually. While termites are present all year, fall and winter can worsen an already-existing situation. Subterranean termites burrow deeper into the ground to survive cold weather, allowing the infestation to cultivate undetected until the following spring. Before you realize, entire colonies are ready to do significant damage to the wood structures of your home. How can you tell if you have termites? You may notice blisters on painted wood surfaces, pinhole-sized holes, and hollow-sounding wood.

Stink Bugs

As the name suggests, stink bugs release an unpleasant odor when they feel threatened or are squished. Not what you want in your home or office! Brown marmorated stink bugs are the most common type, ranging in size from about 1/4″ to 3/8″, so they’re very small and difficult to detect until you have a lot of them. The brown marmorated stink bug is an invasive species that’s taking over more and more territory across the country. They breed quickly, so if you start noticing them don’t wait, give us a call right away.

Asian Lady Beetles

Asian lady beetles are a type of beetle that look very similar to ladybugs, but they tend to be a bit larger, and not all have spots. They typically can be found in groups communicating with each other using pheromones – so if one lady beetle finds its way into a nice warm crack in your home, it will likely leave a signal to attract many more. Asian lady beetles do not pose any direct threat to your home’s structure and don’t bite or sting, but they can trigger allergic reactions for individuals with sensitivities and breathing problems. Additionally, they can cause unsightly stains around the house with their waste.


Generally, wasps die off before each winter and the colonies do not overwinter like the rest of the creatures on this list. But to ensure the colony’s survival the following year, fertilized queens will find a warm hiding spot to overwinter, often in stumps or hollow logs outdoors, or in protected structures like crawlspaces and attics. Make sure to have your house checked for wasp queens during the winter to avoid having dangerous nests on your property the following year when it gets hot again.

Reports of Rodents Surge During the Pandemic

Rodents are infesting more homes during the pandemic in Bristol TN - Leo's Pest Control

Rats and mice are typically common this time of year, but 2020 is seeing a surge in rodent activity due to the pandemic. With the shutdowns and restrictions put on restaurants and bars, rodents suddenly were deprived of their normal food source. This in turn caused them to look to residential homes for sustenance. Now with the weather getting colder, rodents will look to make their way inside your home for the coming months. This Rodent Awareness Week, it’s important to learn how to protect your home from rodents and all of the dangers they bring. Keep reading for expert tips from the team at Leo’s.

Rodents & Coronavirus

Rodents may be responsible for transmitting some of the world’s worst diseases, but COVID-19 is thankfully not one of them. Although there is no evidence to suggest that they are spreading this disease, there are still other diseases they are linked to. Also, a rodent infestation at any time can lead to structural damage.

Restaurant closures have caused an uptick in residential rodent sightings as rats and mice become bolder in their hunt for resources. This directly correlates to a bigger risk of infestations and rodent-spread issues. While they won’t transmit COVID-19 to you or your family, it remains crucial to keep these pests out and away from your home all year long.

Prevention Tips for Rodents

Now is the time to protect your property from rodents and the damage they can cause. Leo’s best rodent prevention tips are as follows.

  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.

Dealing With Rodents This Fall?

As mentioned previously, rodents are more abundant (and more aggressive) than ever. If you find yourself with a rodent infestation, it’s important to act fast. The rodent exterminators at Leo’s Pest Control can work with you to implement a custom rodent control plan. Contact us today to learn more.

Watch Out for Asian Lady Beetles This Fall

Asian lady beetles infest Bristol TN homes in the fall - Leo's Pest Control

The Asian lady beetle is often confused for a normal ladybug, but they are actually quite different. Asian lady beetles are a common fall pest problem as they look to seek shelter before the cold months ahead. Similarly to the boxelder bug and stink bug problems this time of year, Asian lady beetles will flock to the side of your home to bask in the sun on colder fall days. This is when they may crawl indoors through windows, doors, or other cracks and crevices. Once indoors, they’ll gravitate toward windows but can also be found in attics, in curtains, and more. While not the most dangerous pest problem, you definitely don’t want these beetles flying around your Bristol TN home! Read on for expert info on the Asian lady beetle from our team of experts at Leo’s Pest Control.

All About Asian Lady Beetles in Tennessee

It can be easy to misidentify an Asian lady beetle for a ladybug. Here’s how to tell them apart:

  1. Asian lady beetles are slightly larger than ladybugs.
  2. They can be off-red, orange, or even a mustard color.
  3. Asian lady beetles have two white oval markings on the spot behind their head.
  4. Some have an M-shaped mark on the pronotum.
  5. The beetles can leave behind an odorous fluid when crushed.

Tips to Keep Asian Lady Beetles Out in the Fall

When the temperature starts to dip in the fall months, Asian lady beetles will begin to look for shelter indoors. After basking in the sun on the south or western facing wall of a structure, they can get indoors through any opening. Our top tips to keep Asian lady beetles out of your home this fall include:

  • Repair or replace damaged screens on doors and windows.
  • Replace the weather stripping around windows and doors.
  • Use caulk to seal cracks around windows, doors, utility pipes, siding, behind chimneys, and around any other openings.
  • Possibly plant some mums in your garden or around your home. These beetles are not fans of the plants and will avoid them at all costs.
  • Try out a natural deterrent using citrus or citronella scents. Make a spray with orange or lemon essential oil diluted with water, and spray around your windows or doors.

How to Get Rid of Asian Lady Beetles

If you start to notice these insects inside your property, there’s no need to panic. These beetles may bite, but their bites are not known to be dangerous. You can use a vacuum cleaner to contain them, but make sure to dispose of them in a sealed bag. The residential exterminators at Leo’s know just how distressing any type of pest problem is inside your home, which is why we’re here to help. Contact us today for assistance with Asian lady beetles.
