Anyone in Westminster 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 Westminster average near 19°F, so termites retreat deeper into the soil, though colonies under heated basements can stay active all winter.

- 3Discarded wings caught in spider webs.
- 4Mud in cracks of subfloor or joists.

- 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 Westminster.
A provider who works Westminster 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. Westminster 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. Across Westminster, 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 Westminster usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Westminster'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.
Sealing the gap where pipes enter the house takes away one of the easiest routes in. It won't replace treatment, but it helps.Which termites live around Westminster.
It needs steady moisture. The termite you're most likely to meet in Westminster is the arid-land subterranean termite. It nests in soil and builds mud tubes to reach wood.
When termites swarm here.
Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves. Across Westminster, 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.
Where to look around your house.
The same advice applies across the area, from Westminster out to Arvada and Thornton. Plenty of homes in Westminster have basements, so check where the wood framing sits on top of the foundation wall. Look around window wells and unfinished walls. Outside, check porches, steps and decks that touch soil. Wood should stay several inches above the ground.
A year of termites in Westminster.
- Spring: swarm season in Westminster, often on a warm day after rain. Check windowsills for wings. - Summer: with highs around 89°F in Westminster, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 16 inches of rain a year in Westminster, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Westminster, before swarm season starts.
Ways to keep the cost down.
- 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. - Book before swarm season, when schedules fill up. - Get two or three quotes, and compare what each one covers.
What happens at an inspection.
A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help. 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.
Termites or ants?
- 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. - 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.
Getting ready for treatment day.
Keep kids and pets inside while the Westminster crew applies the product, and ask how long to stay off treated soil. Around Westminster, swarms usually show up from July through September as the summer rains start. Drill holes in slabs or patios get patched afterward. 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.
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 Westminster'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 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 do I need to do before and after treatment? - Which termites did you find, and where?
What affects the price
- Cubic footage under the tent for fumigation.
- Annual renewal and monitoring fees.
- Number of bait stations required.
- Slab, crawl space, or basement construction.
- Extent of existing damage needing repair.
- Species: subterranean, drywood, or Formosan.
- Time of year and how booked up local companies are.
- Attached garages, decks, and additions.

What's your biggest concern about termite control costs?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. 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.
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.

When termites are busiest around Westminster
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'.

Simple ways to keep termites away
- Check the foundation for mud tubes every spring.
- Install a vapor barrier over crawl space soil.
- Trim shrubs so foundation walls stay visible and dry.
- Use borate-treated or pressure-treated lumber for repairs.
- Set deck and porch posts on concrete, not soil.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?
Across Westminster, some tropical termites grow fungus gardens inside the nest and eat the harvest.
Across Westminster, soldier termites can't feed themselves, so the workers feed them mouth to mouth.
Questions people ask
Is a bait system cheaper than a liquid treatment?
A liquid barrier has no monthly checks. Ask for both prices. Not usually upfront. Across Westminster, bait costs about the same to install, plus a yearly monitoring fee.
Why do termite quotes vary so much?
Drilling through concrete adds labor. Compare what's included, line by line. Companies measure differently and use different products. Some include a warranty or yearly checks.
How much does a termite inspection cost?
Some companies credit it toward treatment if you go ahead. It's worth asking. Usually $75–$250.
Does homeowner insurance pay for termite damage?
Most policies treat termite damage as preventable. That's why catching it early matters. Usually not.
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
What does a WDI report include?
It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach. It lists any termites or damage found.
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.
Across Westminster, 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.
When is termite swarming season?
Across Westminster, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Westminster, 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 Westminster, the usual culprit is the arid-land subterranean termite.
