What to look for
Termites work quietly. A colony can feed inside a wall for years. Winter lows around Commerce City average near 18°F, so termites retreat deeper into the soil, though colonies under heated basements can stay active all winter. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Blistered or bubbling paint on wood surfaces.
- 2Termite activity reported at a neighbor's home.
- 3Termite tubes hanging down from ceilings or joists.
- 4Buckling laminate or warped hardwood flooring.
- 5Piles of identical shed wings on windowsills.
- 6Tiny pinholes in drywall rimmed with mud.
Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.
- Damage hides behind drywall, flooring and trim.
- Homeowners insurance usually doesn’t cover termite damage.
- An active infestation can complicate a home sale.

Local termites conditions in Commerce City.
A provider who works Commerce City and Colorado every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Knowing Commerce City's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. An inspection in Commerce City usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around Commerce City, the area is mostly suburban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by. Commerce City sits in a semi-arid climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.When termites swarm here.
Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house. A swarm outside means a colony is nearby. Around Commerce City, arid-land subterranean termites usually swarm in spring and early summer, often on a warm day after rain. Swarm season is when termites show themselves.
Where to look around your house.
The same advice applies across the area, from Commerce City out to Thornton and Denver. Wood should stay several inches above the ground. Outside, check porches, steps and decks that touch soil. Look around window wells and unfinished walls. Plenty of homes in Commerce City have basements, so check where the wood framing sits on top of the foundation wall.
A year of termites in Commerce City.
- Spring: swarm season in Commerce City, often on a warm day after rain. Check windowsills for wings. - Summer: with highs around 89°F in Commerce City, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 14 inches of rain a year in Commerce City, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Commerce City, before swarm season starts.
What happens at an inspection.
Most inspections take an hour or two. The inspector walks the outside of the house first. They check the foundation, the soil line and nearby wood. Inside, they check the garage, baseboards, plumbing gaps and the attic. They'll check the basement walls and sill plate. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help.
Termites or ants?
- Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Debris: termites leave mud. Carpenter ants leave sawdust. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
Prep is light for liquid treatments and bait stations. Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines. Keep kids and pets inside while the Commerce City crew applies the product, and ask how long to stay off treated soil. Around Commerce City, swarms usually show up from July through September as the summer rains start. Drill holes in slabs or patios get patched afterward.
Mulch and termites.
Pull mulch back from the foundation and keep the layer thin. A dry gap along the house makes mud tubes easier to spot; in Commerce City's dry climate the risk is irrigation and leaky hose bibs rather than rain. Wood chips touching the siding trap the moisture termites are after.
Questions to ask before you sign.
- What do I need to do before and after treatment? - What does the yearly renewal cost? - What does the warranty cover, and for how long? - Is the whole foundation treated, or just one spot? - What product or system will you use? - Which termites did you find, and where?
What affects the price
- Time of year and how booked up local companies are.
- Access to crawl spaces and attics.
- Number of bait stations required.
- Amount of drilling through concrete and patios.
- Extent of existing damage needing repair.
- Warranty type: retreatment only or damage repair.

What's your biggest concern about termites?
When to call for help
Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
What you can do yourself
Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house. Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see.

Questions people ask
Do I need a termite inspection when buying a house?
Ask your agent when it's due. Either way, it's cheap peace of mind. Many lenders ask for a wood-destroying insect (WDI) report. Usually, yes.
Does fumigation kill subterranean termites too?
It doesn't reach a colony living in the soil. Tenting clears termites inside the house. Not reliably.
How do I choose a termite company?
Compare the proposals, not just the totals. Ask what the warranty covers. Ask which termites they found and what product they'll use. Make sure they're licensed in Colorado.
Do I have to leave my house during termite treatment?
Everyone leaves for two to three days, pets and houseplants included. Fumigation is different. Not for a soil treatment or bait stations.
Are termite baits or liquid treatments more common?
Around Commerce City, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Commerce City, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
Are termites common in Colorado?
