Denver Just Landed Among the Worst U.S. Cities for Bed Bugs — Here's What That Means for Your Home

Denver just made a list nobody wants to be on. According to recent reporting from FOX31 and other local news outlets, the metro was ranked the 11th-worst city in the country for bed bugs — up three spots from last year. The ranking is built from where the most bed bug treatments were actually performed over the past year, so it reflects real jobs in real homes rather than survey guesswork.

We're not surprised. Bed bugs are already the single most common call we take in the Denver Metro Area, and the corridors where they spread fastest — dense apartments, short-term rentals, and a city built around a major travel hub — are exactly the ones that keep growing. Here's what's driving the climb, how to catch a problem before it takes over a home, and what we actually do about it.

Why Denver keeps climbing the bed bug list

Bed bugs don't care how clean your home is or what you earn — they care about two things: people and proximity. The Front Range gives them plenty of both.

• Apartment and multi-family density. Bed bugs travel building-to-building through wall voids, shared laundry rooms, and adjoining units. The apartment-heavy corridors along Colfax, in Aurora near Iliff and Buckley, and across LoDo and Capitol Hill high-rises are where they move fastest.
• A travel-hub city. Denver International is one of the busiest airports in the world, and bed bugs are hitchhikers — they ride home in luggage from hotels, conferences, and vacations, then set up in the bedroom.
• Short-term rentals. Heavy Airbnb and vacation-rental turnover means a lot of unfamiliar luggage passing through a lot of beds. One infested guest can seed the next dozen.
• Used furniture. A curb-side couch or a marketplace mattress is the classic way a single-family home picks them up.

How to tell if you actually have bed bugs

People panic over every small bite and every speck on the sheets. Most of the time it's nothing. Here's what actually points to bed bugs, in the order you'll usually notice it:

• Small reddish-brown stains on sheets or along mattress seams — digested blood after they feed
• Tiny black dots (like ground pepper) in mattress seams, along baseboards, or behind the headboard — fecal spotting
• Bites in rows or clusters on skin exposed while sleeping — arms, shoulders, neck, back
• Shed skins or pale, translucent eggs tucked into seams and cracks
• A sweet, musty odor in a heavily infested room

The bugs themselves are flat, reddish-brown, and about the size of an apple seed. They hide by day in mattress seams, box springs, headboards, baseboards, electrical outlets, and the joints of upholstered furniture — almost always within about eight feet of where someone sleeps. If you're finding the evidence but not the bugs, that's normal. They're built to stay out of sight.

Why the hardware-store spray makes it worse

This is the mistake we clean up after most often. The over-the-counter foggers and sprays you can buy at Home Depot mostly repel bed bugs rather than eliminate them — so instead of killing the population, they scatter it. Bugs that were concentrated in one bed spread into adjacent rooms, deeper into wall voids, and into a neighboring apartment. Worse, repeated DIY spraying is exactly how resistant populations develop. By the time people call us, a one-room problem has often become a three-room problem, and it's harder to solve than if they'd left it alone.

Bed bugs are one of the few pests where doing nothing is genuinely better than doing the wrong thing. Don't throw out the mattress in a panic either — you usually don't need to.

Coming home from a trip? Unpack outside — never in the bedroom

This is the single habit we wish every Denver traveler had, because the suitcase is how most of these jobs start. When you get home, do not carry the bag into the bedroom and open it on the bed. Unpack outside, in the garage, or on a hard surface like a patio or driveway — somewhere a hitchhiker has nowhere to hide if it drops out.

Do it even if everything in the bag is clean. Clean laundry can still be carrying a bed bug or an egg, and it costs you nothing to be careful. Take the clothes straight from the bag to the dryer and run them on high heat — heat is what actually kills them, not detergent, not a cold wash.

And check the suitcase itself. Bed bugs get into the luggage, not just what's packed in it — they tuck into the zipper track, the seams, the lining, the wheel wells, and the inside of the outer pockets. Empty it completely, look it over in good light, vacuum it out, and store it somewhere other than the bedroom closet. A bag that goes back under the bed still loaded is how a trip turns into an infestation three weeks later.

What we do about it

Every job starts with an inspection, and you get your estimate free at the time of that inspection. We confirm it's actually bed bugs, map out where they're harboring, and walk you through what we're going to do before anything is scheduled — no treatment sold on a guess.

From there we use conventional treatment: EPA-registered residual products applied to the harborage zones — mattress seams, box springs, baseboards, outlets, and wall voids — that's the approach proven to work in Front Range housing. Because of how bed bugs breed, follow-up visits are almost always part of the job, and we build those into the original quote rather than nickel-and-diming you for each return trip. And if they turn up again inside our warranty period, we come back and re-service free of charge.

Keeping them out after they're gone

Once an active infestation is eliminated and you don't reintroduce them, bed bugs don't come back on their own. The habits that keep them out:

• Inspect hotel mattress seams and headboards before you unpack, and keep luggage off the bed and floor
• Never bring home used mattresses, couches, or upholstered furniture from the curb or an unknown seller
• Unpack outside or in the garage after every trip — never on the bed — and check the suitcase seams, zippers, and pockets before you store it
• Bag and dryer-treat travel clothing on high heat for 30 minutes when you get home, clean or not
• Encase mattresses and box springs in bed-bug-proof covers
• Reduce clutter around beds — fewer hiding spots means faster detection

Think you've got them? Call sooner, not later

Bed bugs are the one pest where a two-week head start changes everything. A female lays one to five eggs a day, and a single missed one can rebuild a colony in a couple of months — so the sooner we inspect, the smaller and cheaper the job. If you're seeing the signs above anywhere across Denver, Aurora, Lakewood, or the wider Front Range metro, don't wait for it to spread to the next room.
