Anyone in Centennial who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Winter lows around Centennial 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.

- 3Dry hexagonal pellets under window frames or eaves.
- 4Crumbling baseboards behind furniture.
- 5Termite tubes hanging down from ceilings or joists.

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 Centennial.
Across Centennial, 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. An inspection in Centennial usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Centennial'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. A provider who works Centennial 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. Centennial 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.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.Which termites live around Centennial.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in Centennial is the arid-land subterranean termite.
When termites swarm here.
Across Centennial, arid-land subterranean termites usually swarm in spring and early summer, often on a warm day after rain. A swarm outside means a colony is nearby. A swarm inside usually means it's in the house. Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves.
Where to look around your house.
Look around window wells and unfinished walls. Outside, check porches, steps and decks that touch soil. Wood should stay several inches above the ground. The same advice applies across the area, from Centennial out to Parker and Aurora. Plenty of homes in Centennial have basements, so check where the wood framing sits on top of the foundation wall.
A year of termites in Centennial.
- Spring: swarm season in Centennial, often on a warm day after rain. Check windowsills for wings. - Winter: a good time to book an inspection in Centennial, before swarm season starts. - Fall: with about 16 inches of rain a year in Centennial, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 88°F in Centennial, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
Ways to keep the cost down.
- Book before swarm season, when schedules fill up. - Get two or three quotes, and compare what each one covers. - Fix leaks and drainage first. Moisture brings termites back. - Ask about both bait and liquid options for your house. - If you already have a warranty, keep the renewal current.
What happens at an inspection.
Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. They'll check the basement walls and sill plate. Inside, they check the garage, baseboards, plumbing gaps and the attic. They check the foundation, the soil line and nearby wood. The inspector walks the outside of the house first. Most inspections take an hour or two. Photos help.
Termites or ants?
- Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Wings: termite wings are all the same length. Ant wings aren’t. - Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Debris: termites leave mud. Carpenter ants leave sawdust.
Getting ready for treatment day.
Keep kids and pets inside while the Centennial crew applies the product, and ask how long to stay off treated soil. Around Centennial, swarms usually show up from July through September as the summer rains start. Flag sprinkler heads and buried lines. Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations. Drill holes in slabs or patios get patched afterward.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Centennial's dry climate the risk is irrigation and leaky hose bibs rather than rain. Pull mulch back from the foundation and keep the layer thin. 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? - Which termites did you find, and where? - What product or system will you use? - Is the whole foundation treated, or just one spot? - What does the warranty cover, and for how long? - What does the yearly renewal cost?
What affects the price
- Warranty type: retreatment only or damage repair.
- Annual renewal and monitoring fees.
- Access to crawl spaces and attics.
- Time of year and how booked up local companies are.
- Species: subterranean, drywood, or Formosan.
- Number of bait stations required.
- Slab, crawl space, or basement construction.
- Liquid barrier versus bait station system.
📊
What's your biggest concern about termite control costs?
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.
Termites in Centennial

With summer highs around 88°F, Centennial's semi-arid climate decides when local termites are busiest. Not every house gets them, but plenty do. Termites are a steady, moderate risk in Colorado. Centennial only sees about 16 inches of rain a year, so local termites gather wherever water collects, like sprinkler zones, hose bibs and AC drain lines.

When termites are busiest around Centennial
July–September (desert subterranean, late afternoon/evening with summer rains); summer–fall (drywood). UC IPM: 'Heterotermes aureus flies in the late afternoon or early evening in July, August, and September', which coincides with the Southwest monsoon months. Arizona Extension lists Heterotermes aureus as an 'important structural pest' and notes drywood species Incisitermes minor and Marginitermes hubbardi in the desert Southwest. Drywood swarmers appear 'during daytime hours during summer and fall'.

Questions people ask
Does homeowner insurance pay for termite damage?
That's why catching it early matters. Most policies treat termite damage as preventable. Usually not.
Why do termite quotes vary so much?
Compare what's included, line by line. Drilling through concrete adds labor. Some include a warranty or yearly checks. Companies measure differently and use different products.
How much does a termite inspection cost?
It's worth asking. Some companies credit it toward treatment if you go ahead. Usually $75–$250.
Is a bait system cheaper than a liquid treatment?
Ask for both prices. A liquid barrier has no monthly checks. Across Centennial, bait costs about the same to install, plus a yearly monitoring fee. Not usually upfront.
Does fumigation kill subterranean termites too?
It doesn't reach a colony living in the soil. Tenting clears termites inside the house. Not reliably.
Will termites come back after treatment?
That's what yearly inspections and renewal plans are for. Treatments wear down and new colonies move in. They can.
Can termites damage a house on a concrete slab?
Inspectors check those spots first. They come up through expansion joints, plumbing gaps and small cracks. Yes.
Across Centennial, can a pest control company do a termite inspection for a home sale?
Almost always. If you are buying or selling a house, a termite letter is easy to source: 85% of locations in PCT magazine's 2025 termite market report (about 145 pest-control professionals, 2024 operations) offered real-estate inspections.
Are termites common in Colorado?
Around Centennial, the usual culprit is the arid-land subterranean termite.
