- The usual fix is a soil barrier or bait stations.
- An inspection typically costs $75–$250.
- Insurance usually doesn’t cover termite damage.
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
Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs. 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.
- 1Mud tubes running up foundation walls or piers.
- 2Sagging or spongy floors near exterior walls.
- 3Dry hexagonal pellets under window frames or eaves.
- 4Tiny pinholes in drywall rimmed with mud.
- 5Crumbling baseboards behind furniture.
- 6Termite 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.

The termite you're most likely to meet in Centennial is the arid-land subterranean termite. It needs steady moisture. It nests in soil and builds mud tubes to reach wood.
Local termites conditions in Centennial.
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. Around 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. 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 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. 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.
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.
A swarm outside means a colony is nearby. Around Centennial, 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. Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house.
Where to look around your house.
Outside, check porches, steps and decks that touch soil. Look around window wells and unfinished walls. Plenty of homes in Centennial have basements, so check where the wood framing sits on top of the foundation wall. The same advice applies across the area, from Centennial out to Parker and Aurora. Wood should stay several inches above the ground.
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.
What happens at an inspection.
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. 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.
Termites or ants?
- Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t. - 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.
Getting ready for treatment day.
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. 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.
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 product or system will you use? - Which termites did you find, and where? - 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 affects the price
- Extent of existing damage needing repair.
- Attached garages, decks, and additions.
- Linear feet of foundation to be treated.
- Amount of drilling through concrete and patios.
- Liquid barrier versus bait station system.
- Wells, drains, or water features limiting chemical use.

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
Store-bought sprays usually kill only the termites you see. It also needs even coverage around the entire foundation. The product has to reach the whole colony. Treating an active colony is harder. Keep firewood away from the house. Fix leaks and clear gutters. Pull mulch back from the foundation. Some of the work is yours.
Termites in Centennial
A typical home in Centennial is worth around $595k, which puts a few hundred dollars for an inspection and prevention in perspective. Centennial has a semi-arid climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. Around Centennial, most of the housing is suburban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. Around Centennial, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. A local provider who knows Centennial and Colorado can point out the specific conditions that matter most here before you commit to a plan. 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. Termites are a steady, moderate risk in Colorado. Not every house gets them, but plenty do. With summer highs around 88°F, Centennial's semi-arid climate decides when local termites are busiest.

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'.

- Keep the termite renewal contract current after treatment.
- Seal cracks in the foundation and slab.
- Set deck and porch posts on concrete, not soil.
- Remove tree stumps and buried wood near the house.

Questions people ask
Are mud tubes always a sign of active termites?
Break off a piece and check back in a week. If it's rebuilt, they're active. Not always. Old tubes can stay on a wall for years.
How do I know if I have termites or flying ants?
Ants have a pinched waist; termites don't. Save one in a bag for the inspector. Check the wings and the waist. Termite wings are all the same length.
How long do termite bait stations take to work?
Termites have to find the stations first. Then the bait spreads through the colony. Usually several weeks to a few months.
Is termite treatment safe for kids and pets?
Bait stations are locked and buried. Ask for the label and follow any re-entry times. Used according to the label, yes. Soil treatments stay in the ground.
Will termites come back after treatment?
Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for. They can.
Can I treat termites myself instead of hiring a professional?
Around Centennial, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Centennial, 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?
Around Centennial, the usual culprit is the arid-land subterranean termite.
