Anyone in Fort Collins 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 Fort Collins average near 17°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.
- 1Dry hexagonal pellets under window frames or eaves.
- 2Termite tubes hanging down from ceilings or joists.
- 3Mud in cracks of subfloor or joists.
- 4Discarded wings caught in spider webs.
- 5Termite activity reported at a neighbor's home.
- 6Wood that sounds hollow when tapped.
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.

In a basement, the wooden sill plate on top of the block wall is the first piece of wood termites reach.Which termites live around Fort Collins.
The termite you're most likely to meet in Fort Collins is the arid-land subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture.
Local termites conditions in Fort Collins.
Fort Collins 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. In Fort Collins, the area is mostly urban, 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 Fort Collins usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Fort Collins'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 Fort Collins 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.
Sealing the gap where pipes enter the house takes away one of the easiest routes in. It won't replace treatment, but it helps.When termites swarm here.
Swarm season is when termites show themselves. In Fort Collins, 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.
Where to look around your house.
Plenty of homes in Fort Collins 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. The same advice applies across the area, from Fort Collins out to Loveland and Greeley.
A year of termites in Fort Collins.
- Winter: a good time to book an inspection in Fort Collins, before swarm season starts. - Fall: with about 16 inches of rain a year in Fort Collins, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 87°F in Fort Collins, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Spring: swarm season in Fort Collins, often on a warm day after rain. Check windowsills for wings.
What happens at an inspection.
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. 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.
Termites or ants?
- 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. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth.
Getting ready for treatment day.
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. 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.
Mulch and termites.
Wood chips right against siding hold moisture termites like. A dry strip along the house lets you spot mud tubes. Keep mulch thin and pull it back from the foundation.
Questions to ask before you sign.
- 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 do I need to do before and after treatment?
What affects the price
- Local labor rates and licensing requirements.
- Amount of drilling through concrete and patios.
- Slab, crawl space, or basement construction.
- Cubic footage under the tent for fumigation.
- Species: subterranean, drywood, or Formosan.
- Warranty type: retreatment only or damage repair.

What's your biggest concern about termites?
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.

Simple ways to keep termites away
- Use borate-treated or pressure-treated lumber for repairs.
- Keep gutters clean so water does not pool.
- Install a vapor barrier over crawl space soil.
- Caulk gaps around plumbing and utility penetrations.
- Seal cracks in the foundation and slab.
- Extend downspouts so water drains away from walls.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?

Questions people ask
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.
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.
What does a WDI report include?
It only covers areas the inspector could reach. It also notes conditions that invite them, like wood touching soil. It lists any termites or damage found.
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.
When is termite swarming season?
In Fort Collins, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Fort Collins, 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 Fort Collins, the usual culprit is the arid-land subterranean termite.
