The High Country Pest Report
Fall Edition
Seasonal Pest Knowledge for Colorado’s Mountain Homes and Businesses
Published Seasonally by Quality Pest Solutions
Welcome to the Fall Edition
Fall changes the conditions around Colorado’s mountain properties. Nights become colder, vegetation dies back, and snow begins limiting access to outdoor food and shelter. These changes influence some pests, while others remain a concern regardless of the season.
Mice can enter buildings and establish nests in protected spaces. Some spiders become more noticeable indoors. Voles continue feeding outside, where snow can conceal their activity. Bed bugs follow a different pattern: they move between properties on belongings rather than seeking shelter from cold weather.
Understanding these differences helps property owners choose useful prevention measures instead of treating every pest concern the same way.
At Quality Pest Solutions, we are a local, family-owned business based in Summit County, serving homes, businesses, vacation rentals, hotels, and HOA communities throughout Summit, Eagle, Grand, Clear Creek, Lake, and Park Counties.
This edition explains seasonal pest behavior, signs worth investigating, and practical steps for protecting your property as winter approaches.
At a Glance
🐭 Mice
Watch Access Points and Stored Food
Garages, utility rooms, kitchens, and storage areas can provide food and protected nesting spaces. Droppings, gnawed packaging, and shredded material deserve attention.
🛏️ Bed Bugs
A Year-Round Concern
Bed bugs can hitchhike on luggage, clothing, and furnishings. Regular awareness is especially valuable for hotels and vacation rentals with frequent guest turnover.
🕷️ Spiders
Understand What You Are Seeing
Some species wander indoors during early fall. Others already live inside buildings. One spider does not automatically indicate an infestation.
🌱 Voles
Active Beneath Winter Snow
Voles do not hibernate. Their feeding can damage vegetation and tree bark while snow hides the evidence until spring.
Mice: Why Buildings Become Attractive
Mice need food and shelter, and buildings can provide both. Protected spaces allow them to nest away from disturbance, while accessible food supports continued activity.
Fall is a useful time to check a property because snow has not yet concealed many exterior conditions.
Garages deserve particular attention. Birdseed, pet food, cardboard boxes, and stored materials can provide food or shelter. Gaps around garage doors and utility penetrations may allow access to adjoining spaces.
Commercial buildings have additional considerations. Deliveries, receiving doors, stockrooms, employee break rooms, and food preparation areas all deserve regular checks.
For restaurants, food beneath equipment may be missed during routine surface cleaning. For retail shops and offices, stored snacks and quiet utility areas can support activity even when customer-facing spaces appear clean.
Watch for:
Droppings near walls or stored supplies.
Gnawed food packaging.
Shredded paper or insulation.
Repeated scratching sounds.
Nesting material in undisturbed areas.
These clues deserve investigation. Their location can help guide an inspection, but does not necessarily identify where mice entered.
💡 Did You Know? Mice can fit through openings approximately one-quarter inch wide.
A gap that looks insignificant around a door seal or utility line can provide access.
Check garage corners, exterior doors, accessible foundation openings, and places where pipes or cables enter the building.
Repairs should use materials suitable for resisting rodents. Foam alone can be chewed. Structural work should be completed by someone qualified for the repair.
Quality Pest Solutions provides rodent mitigation and identifies potential entry points. We do not perform building repairs or sanitation. Addressing access and food sources alongside treatment helps reduce conditions supporting rodent activity.
🏔️ Mountain Tip: Make storage spaces easier to inspect.
Keep pet food and birdseed in sturdy containers with tight lids. Remove spilled seed and reduce clutter around walls.
Arrange storage so corners and door edges remain accessible. Keep firewood away from siding and check it before bringing it indoors.
For businesses, assign responsibility for checking receiving areas and stockrooms. A consistent routine helps staff notice changes sooner and report the exact location.
Bed Bugs: Hitchhikers, Not Seasonal Invaders
Bed bugs do not need falling temperatures to become a problem. They can travel on luggage, clothing, bedding, boxes, and furniture.
Hotels, vacation rentals, apartments, and homes can all encounter them. A clean property can still receive bed bugs, and an infestation does not establish that someone has neglected housekeeping.
Bed bugs feed on blood and commonly hide near places where people rest. Their flattened bodies allow them to occupy small crevices.
Common hiding places include:
Mattress seams and piping.
Box springs.
Bed frames and headboards.
Nearby cracks and crevices.
Upholstered furniture.
Bed Bugs Are Here in the High Country
A common misconception is that bed bugs do not occur in Colorado’s mountain communities. They do! The photo below shows an infestation Quality Pest Solutions encountered last week, with evidence concentrated along an upholstered furniture seam.
Bed bugs can arrive on luggage, clothing, and furniture. Check beyond the mattress: seams and folds in upholstered furniture are also hiding places. This is an established infestation; early signs can be much less obvious.Early infestations may be difficult to detect because relatively few insects are present. Heavy-infestation photographs show recognizable evidence, but early signs can be much less obvious.
Correct identification matters. Other insects and debris can be mistaken for bed bugs, leading to unnecessary worry or inappropriate treatment.
💡 Did You Know? Bites alone cannot confirm a bed bug infestation.
Skin reactions can resemble other insect bites or unrelated irritation. Some people do not react to bed bug bites at all.
Look for physical evidence: live bugs, shed skins, dark spotting, or rusty stains around sleeping areas.
If you find suspicious evidence, photograph it and record the location. Contact a pest professional for identification before moving potentially affected furniture between rooms or properties.
Bed Bug Awareness for Hotels and Vacation Rentals
Housekeeping teams regularly handle bedding and access sleeping areas, putting them in a useful position to notice changes.
Include visual checks of mattress seams, bed frames, and accessible headboard areas during turnovers. These checks support awareness, but cannot guarantee that a room is free of bed bugs.
Give staff a clear reporting procedure. Useful details include the room or unit, the location of evidence, photographs, and when the concern was noticed.
Take guest reports seriously while recognizing that a complaint or skin reaction does not establish an infestation.
In adjoining accommodations, share relevant information with the pest professional so surrounding spaces can be considered when appropriate.
Travelers can check mattresses, headboards, and luggage racks upon arrival. Use an inspected luggage rack rather than placing bags on beds, and inspect luggage after returning home.
Spiders: When Sightings Need Attention
Some spiders wander indoors during early fall. Others occupy garages, basements, crawl spaces, and quiet corners throughout the year.
Spiders feed on insects and other small arthropods, making them useful predators. An occasional sighting does not automatically mean extensive treatment is needed.
Repeated sightings or heavy webbing warrant a closer look at the conditions supporting activity.
Clutter, woodpiles, dense vegetation, and accessible openings can provide shelter or access. Insects attracted to exterior lighting may also provide food.
Remove webs, reduce clutter, and check door seals and screens. Include quiet storage rooms and utility spaces in regular property checks.
For persistent nuisance activity, targeted treatment may help when paired with changes to habitat and access.
Voles: Landscape Damage Can Continue Through Winter
Voles remain active year-round. They create runways through grass and feed on vegetation, including bark on trees and shrubs.
Snow can cover their movement and allow feeding damage to develop out of sight. Property owners may discover the damage only after spring melting exposes lawns and plantings.
Fall provides an opportunity to inspect vulnerable landscaping before snow cover.
Watch for narrow surface trails, small burrow openings, and bark damage near ground level. Young trees and shrubs deserve particular attention.
Reducing dense vegetation and accumulated debris around vulnerable plants can limit shelter. Suitable trunk protection can also help.
For HOAs and commercial properties, document affected areas and coordinate with landscape staff. Identification matters because different burrowing animals require different management approaches.
What Should You Watch For?
During a fall property walkthrough, look for:
✔ Rodent droppings and damaged packaging.
✔ Worn door seals and accessible gaps.
✔ Suspicious spotting around sleeping areas.
✔ Live bed bugs or shed skins.
✔ Repeated spider sightings or heavy webbing.
✔ Vole runways and damaged bark.
Record where signs appear. Clear information helps maintenance teams and pest professionals investigate the relevant areas.
For businesses, designate a contact for staff reports. For HOAs, make sure residents know how to report concerns involving shared garages, utility spaces, or neighboring units.
Frequently Asked Questions
Will mice disappear when winter arrives?
Not necessarily. Mice inside buildings can remain active through winter. Cold weather does not resolve an established indoor problem.
Can a clean property get bed bugs?
Yes. Bed bugs can arrive on belongings or furniture. Cleanliness alone does not prevent an introduction.
Does every spider sighting require treatment?
No. Consider the species, frequency of sightings, and surrounding conditions before deciding on a response.
Can voles damage trees during winter?
Yes. Feeding beneath snow can damage bark. Monitoring vulnerable plants before snow cover gives owners an opportunity to reduce risk.
Looking Ahead
As winter approaches, maintain regular checks rather than relying on one seasonal walkthrough.
Businesses can review receiving practices, food storage, housekeeping procedures, and responsibility for responding to pest reports.
Homeowners and HOAs can prioritize garages, utility areas, accessible entry gaps, and vulnerable landscaping.
