Homeowners, landlords and anyone buying or selling a house in Arvada, whether you've spotted something or just want to know what to watch for.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Winter lows around Arvada average near 19°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.

- 4Discarded wings caught in spider webs.
- 5Mud in cracks of subfloor 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.

Check under the kitchen sink for dampness and soft cabinet wood. Plumbing walls are a common path for termites coming up from a slab.How treatment works on a typical Arvada home.
Bait stations are the other main option. Inside, they may drill where the floor meets the walls. With a basement, the crew treats soil along the outside. The stations are checked on a schedule, often every few months. Termites carry the bait back to the colony. They're spaced every 10 to 20 feet.
Which termites live around Arvada.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in Arvada is the arid-land subterranean termite.
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. 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. For Arvada homes, arid-land subterranean termites usually swarm in spring and early summer, often on a warm day after rain.
Where to look around your house.
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 Arvada out to Westminster and Lakewood. Plenty of homes in Arvada have basements, so check where the wood framing sits on top of the foundation wall. Look around window wells and unfinished walls.

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. - 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.
Mark sprinkler heads and any buried lines. Move stored boxes away from garage walls. Clear a path along the outside walls. Soil treatments and bait stations need little prep. Any drill holes in a slab or patio get patched. Ask how long to stay off treated soil. Keep pets and kids inside while the crew works outside.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Keep mulch thin and pull it back from the foundation. Wood chips right against siding hold moisture termites like.
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
- Access to crawl spaces and attics.
- Linear feet of foundation to be treated.
- Amount of drilling through concrete and patios.
- Number of bait stations required.
- Attached garages, decks, and additions.
- Annual renewal and monitoring fees.

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

A local provider who knows Arvada and Colorado can point out the specific conditions that matter most here before you commit to a plan. For Arvada homes, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. For Arvada homes, 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. Arvada has a semi-arid climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. A typical home in Arvada is worth around $555k, which puts a few hundred dollars for an inspection and prevention in perspective. With summer highs around 89°F, Arvada'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.

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
What is the difference between subterranean and drywood termites?
Around Arvada, the subterranean kind causes most problems. Drywood termites live inside the wood and leave tiny pellets. Subterranean termites live in soil and build mud tubes.
Are mud tubes always a sign of active termites?
If it's rebuilt, they're active. Break off a piece and check back in a week. Old tubes can stay on a wall for years. Not always.
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 long does termite treatment take?
Fumigation takes two to three days. Bait stations take a few hours to install. A liquid barrier takes half a day to a day.
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.
Can I pay for termite monitoring without a full treatment?
Treat it as a rough guide, not a local count. For Arvada homes, if you want a watchful eye without committing to treatment, fewer than half of companies sell that: 42% of locations in PCT magazine's 2025 termite market report (about 145 pest-control professionals, 2024 operations) offered inspection or monitoring only. Not every company sells it. Sometimes.
Can you treat for termites before building a house?
For Arvada homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Arvada homes, 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 Arvada, the usual culprit is the arid-land subterranean termite.
