The Mountain Pest Report
Mid-Summer Edition
What We're Seeing Across Colorado's Mountain Communities
Published Seasonally by Quality Pest Solutions
Welcome to the First Edition
Welcome to the very first edition of The Mountain Pest Report.
Every season brings different pest challenges to Colorado's mountain communities, and one of the advantages of serving our mountain counties every day is that we get to see those trends develop in real time.
At Quality Pest Solutions, our technicians are in homes, businesses, restaurants, hotels, vacation rentals, HOA communities, and commercial properties throughout Summit, Eagle, Grand, Clear Creek, Lake, and Park Counties every single day. Because we're constantly working throughout the region, we often notice seasonal pest trends before most property owners do.
Each season, The Mountain Pest Report will share what we're seeing in the field, explain why it's happening, and provide practical information to help homeowners, businesses, and property managers stay ahead of seasonal pest activity.
Whether you own a mountain cabin, manage a commercial property, oversee an HOA, or simply want to better understand what's happening around your home, we hope this report becomes a valuable resource throughout the year.
At a Glance
🐜 Carpenter Ants
High Activity
Carpenter ants continue to be our busiest service call this summer. We're seeing increased activity around homes, decks, crawl spaces, garages, trees, firewood, and landscaping throughout the mountains.
🐝 Wasps
Increasing
Many of the small nests that appeared earlier this season are now entering a period of rapid growth. A nest that's only a few inches across today can contain hundreds of wasps before summer ends.
🐭 Rodents
Steady
Rodent activity remains consistent around homes, garages, vacation rentals, restaurants, storage buildings, and commercial properties.
🌱 Pocket Gophers & Voles
Active
Fresh mounds and tunneling continue appearing throughout residential lawns, HOA common areas, parks, golf courses, and commercial landscapes.
Carpenter Ants Continue to Be Our Number One Service Call
Without question, carpenter ants have become the biggest pest issue we're seeing this summer. Nearly every day we are responding to calls from homeowners and businesses that have started noticing large black ants around their property. Unlike the small sugar ants that occasionally wander into kitchens searching for food, carpenter ants are searching for places to establish or expand their colonies.
One of the biggest misconceptions we hear is that carpenter ants eat wood like termites.
They don't. Instead, carpenter ants excavate smooth tunnels inside wood called galleries. These galleries become living spaces for the colony. Although they prefer wood that's already been softened by moisture or decay, large colonies can contribute to structural damage over time if they're allowed to continue expanding.
By mid-summer, colonies have had several months to grow. Worker ants travel farther searching for food, making them much more visible around homes and businesses.
Many people only notice two or three carpenter ants and assume the problem is small.
Unfortunately, that's rarely the case. The ants you see are simply the workers. The colony itself may contain thousands of ants hidden inside a wall, deck, crawl space, tree, stump, or another protected location.
💡 Did You Know?
A mature carpenter ant colony may contain thousands of ants, but you might only see a handful of workers.
Seeing just a few carpenter ants doesn't necessarily mean you have a small problem.
The workers you're seeing are simply searching for food while the rest of the colony remains hidden nearby.
🌲 Why We Watch Trees So Closely
One of the most common questions we've been asked this summer is:
"Are carpenter ants killing my trees?"
The answer is more complicated than a simple yes or no. Healthy trees generally aren't attractive nesting sites. Instead, carpenter ants are usually telling us that something else is happening first. Trees weakened by drought, decay, disease, storm damage, or old wounds become attractive nesting sites because softened wood is much easier for carpenter ants to excavate.
While carpenter ants usually aren't the original cause of a tree's decline, they can accelerate the deterioration of already weakened wood. If you're consistently seeing large black carpenter ants traveling up and down a tree trunk, it's worth taking a closer look. Carpenter ants should be viewed as a warning sign that a tree may already be under stress. Trees located close to homes deserve even more attention because established colonies can eventually spread into nearby structures.
🏔️ Mountain Tip
Never stack firewood directly against your home.
Firewood creates an ideal hiding place for carpenter ants, rodents, spiders, and other pests.Keeping firewood elevated and at least 20 feet away from your home can significantly reduce pest pressure.
Why We're Seeing So Much Activity
One question we hear every summer is:
"Why does everything seem to happen at once?"
The answer is simple.
By July and August:
Insect colonies have matured.
Warm temperatures accelerate reproduction.
Vegetation is thriving.
Food sources are abundant.
Longer days allow insects and wildlife more time to forage.
Everything in nature is connected.
When insect populations increase, predators become more active.
Healthy vegetation supports larger populations of pocket gophers and voles.
That's why multiple pest species often become active at the same time throughout Colorado's mountain communities.
Wasp Colonies Are Growing Quickly
Every wasp colony begins with a single queen.
Throughout spring she builds a small paper nest and raises the first generation of workers. Once those workers emerge, colony growth accelerates rapidly.
A nest that's only a few inches across today can become home to hundreds of wasps before summer ends.
We're commonly finding nests around:
Roof eaves
Decks
Outdoor furniture
Playground equipment
Garages
Restaurant patios
Dumpster enclosures
Outdoor lighting
Finding nests early makes removal much safer and much easier.
Rodents Never Really Leave
Many people associate mice with winter. In reality, summer is often when new infestations begin. Young mice leave established nests searching for food, water, and shelter.
We're finding activity around:
Homes
Garages
Crawl spaces
Vacation rentals
Restaurants
Offices
Storage buildings
Commercial properties
Finding activity early almost always prevents much larger infestations later in the year.
Pocket Gophers & Voles Continue to Damage Landscapes
Fresh pocket gopher mounds continue appearing throughout Colorado's mountain communities. Pocket gophers feed underground while creating extensive tunnel systems that damage lawns, irrigation systems, gardens, young trees, and landscaping.
Voles create surface runways beneath grass and mulch while feeding on vegetation and root systems. Both pests can cause extensive landscape damage if left untreated.
What Should You Watch For?
Keep an eye out for:
✔ Large black carpenter ants
✔ Carpenter ants climbing trees
✔ Fresh piles of sawdust near wood
✔ New wasp nests
✔ Rodent droppings
✔ Fresh pocket gopher mounds
✔ Surface vole runways
Early detection almost always means less damage, lower repair costs, and simpler solutions.
Frequently Asked Questions
Are carpenter ants active all day?
They're most active during the evening and overnight hours, but during midsummer it's common to see them throughout the day, especially along established foraging trails.
Why are carpenter ants suddenly inside my house?
Warm weather increases foraging activity. Workers travel farther searching for food and moisture, making it much more likely you'll notice activity indoors.
Are carpenter ants worse in mountain communities?
They can be. Mountain homes often have abundant trees, natural wood landscaping, crawl spaces, vacation homes, and moisture from snowmelt—all conditions carpenter ants take advantage of.
How can I tell the difference between carpenter ants and termites?
Carpenter ants have a narrow waist, elbowed antennae, and smooth, dark bodies.
Termites have straight antennae, thicker waists, and pale-colored bodies.
Will carpenter ants go away on their own?
Unfortunately, no. Colonies continue to grow throughout the season unless the queen and colony are eliminated.
Looking Ahead
As we move into late summer, we'll be watching for:
Peak yellow jacket activity
Expanding wasp colonies
Increased spider activity around homes
Rodents preparing for cooler weather
Continued carpenter ant activity
Wildlife becoming more visible around neighborhoods
We'll continue sharing what we're seeing each month so homeowners, businesses, and property managers throughout Colorado's mountain communities can stay informed and stay one step ahead of seasonal pest activity.
