Homeowners, landlords and anyone buying or selling a house in Billings, 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 Billings average near 15°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.
- 1Mud tubes running up foundation walls or piers.
- 2Crumbling baseboards behind furniture.
- 3Damage found during a remodel or repair.
- 4Dry hexagonal pellets under window frames or eaves.
- 5Termite tubes hanging down from ceilings or joists.
- 6Mud 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.
- An active infestation can complicate a home sale.

Drywood termites can fly straight into attic framing through vents, so attics belong on the inspection list in warm climates.How treatment works on a typical Billings 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 Billings.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in Billings is the arid-land subterranean termite.
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.
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 Billings 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. Plenty of homes in Billings 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 Billings.
- Summer: with highs around 88°F in Billings, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 14 inches of rain a year in Billings, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Billings, before swarm season starts. - Spring: swarm season in Billings, often on a warm day after rain. 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
- Extent of existing damage needing repair.
- Cubic footage under the tent for fumigation.
- Linear feet of foundation to be treated.
- Attached garages, decks, and additions.
- Species: subterranean, drywood, or Formosan.
- Access to crawl spaces and attics.

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.
Termites in Billings
Billings 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. Montana is on the low end for termites. Low isn't zero, though. With summer highs around 88°F, Billings's semi-arid continental climate decides when local termites are busiest. A typical home in Billings is worth around $330k, which puts a few hundred dollars for an inspection and prevention in perspective.

When termites are busiest around Billings
April–May (spring), later than in the South. Minnesota: 'Termites are uncommon to rare in Minnesota and are generally seen only in the southern third of the state'; 'When present, swarmers are found during spring'. Texas A&M notes the north-south lag: 'In the Panhandle region of Texas, swarms do not occur until April or May'. Kentucky Extension notes swarms are 'Triggered by warmer temperatures and rainfall'.

Simple ways to keep termites away
- Trim shrubs so foundation walls stay visible and dry.
- Keep gutters clean so water does not pool.
- Keep the termite renewal contract current after treatment.
- Use borate-treated or pressure-treated lumber for repairs.
- Address wood-to-soil contact at steps, fences, and trellises.
- Remove tree stumps and buried wood near the house.
In an apartment building, termites travel through shared walls and slab joints, so one unit's problem is the whole building's problem.Did you know?
Some African termite mounds stand more than 25 feet tall.
For Billings homes, some tropical termites grow fungus gardens inside the nest and eat the harvest.
Questions people ask
Do I have to leave my house during termite treatment?
Not for a soil treatment or bait stations. Fumigation is different. Everyone leaves for two to three days, pets and houseplants included.
How do I know if I have termites or flying ants?
Check the wings and the waist. Termite wings are all the same length. Ants have a pinched waist; termites don't. Save one in a bag for the inspector.
Is termite treatment safe for kids and pets?
Used according to the label, yes. Soil treatments stay in the ground. Bait stations are locked and buried. Ask for the label and follow any re-entry times.
Can I treat termites myself?
Prevention, yes. An active colony is harder. The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see.
How long do termite bait stations take to work?
Usually several weeks to a few months. Termites have to find the stations first. Then the bait spreads through the colony.
How much does a pre-construction termite treatment cost?
Professionals reported an average of $883. Anyone building a house can use $883 as a rough yardstick for pre-construction termite treatment, the professional-reported average in Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 respondents, 2024 pricing), while remembering that actual quotes depend on slab size, region and product. When you get quotes in Billings, ask each company what they usually see in your neighborhood.
Are termite treatment prices going up?
For Billings homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Billings 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 Montana?
Low isn't zero, though. Around Billings, the usual culprit is the arid-land subterranean termite.
