Anyone in Greeley 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 Greeley average near 16°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.
- 1Discarded wings caught in spider webs.
- 2Doors and windows that suddenly stick.
- 3Sagging or spongy floors near exterior walls.
- 4Mud in cracks of subfloor or joists.
- 5Wood that sounds hollow when tapped.
- 6Dry hexagonal pellets under window frames or eaves.
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.How treatment works on a typical Greeley home.
They're spaced every 10 to 20 feet. Termites carry the bait back to the colony. The stations are checked on a schedule, often every few months. With a basement, the crew treats soil along the outside. Inside, they may drill where the floor meets the walls. Bait stations are the other main option.
Which termites live around Greeley.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in Greeley is the arid-land subterranean termite.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.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 Greeley 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 Greeley out to Loveland and Fort Collins. Plenty of homes in Greeley have basements, so check where the wood framing sits on top of the foundation wall. Look around window wells and unfinished walls.
A year of termites in Greeley.

Check windowsills for wings.
What happens at an inspection.
They'll check the basement walls and sill plate. 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.
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. Keep pets and kids inside while the crew works outside. Ask how long to stay off treated soil. Any drill holes in a slab or patio get patched. Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation.
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
- Slab, crawl space, or basement construction.
- Linear feet of foundation to be treated.
- Species: subterranean, drywood, or Formosan.
- Warranty type: retreatment only or damage repair.
- Local labor rates and licensing requirements.
- Time of year and how booked up local companies are.

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
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.
Termites in Greeley
Greeley only sees about 14 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 90°F, Greeley's semi-arid climate decides when local termites are busiest. A typical home in Greeley is worth around $400k, which puts a few hundred dollars for an inspection and prevention in perspective. Greeley has a semi-arid climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. For Greeley 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. For Greeley 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. A local provider who knows Greeley and Colorado can point out the specific conditions that matter most here before you commit to a plan.
