Homeowners, landlords and anyone buying or selling a house in Missoula, 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 Missoula average near 18°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.
- 2Blistered or bubbling paint on wood surfaces.
- 3Damage found during a remodel or repair.
- 4Tiny pinholes in drywall rimmed with mud.
- 5Piles of identical shed wings on windowsills.
- 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.

Local termites conditions in Missoula.
An inspection in Missoula usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Missoula'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 Missoula and Montana 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. Missoula sits in a warm summer continental climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. For Missoula homes, 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.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.Which termites live around Missoula.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in Missoula is the arid-land subterranean termite.
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 Missoula 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 Missoula 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 Missoula.
- Summer: with highs around 86°F in Missoula, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 15 inches of rain a year in Missoula, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Missoula, before swarm season starts. - Spring: swarm season in Missoula, often on a warm day after rain. Check windowsills for wings.
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.
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
- Wells, drains, or water features limiting chemical use.
- Amount of drilling through concrete and patios.
- Linear feet of foundation to be treated.
- Extent of existing damage needing repair.
- Liquid barrier versus bait station system.
- Attached garages, decks, and additions.
- Warranty type: retreatment only or damage repair.
- Cubic footage under the tent for fumigation.

What's your biggest concern about termite control costs?
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
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.

Questions people ask
Why do termite quotes vary so much?
Companies measure differently and use different products. Some include a warranty or yearly checks. Drilling through concrete adds labor. Compare what's included, line by line.
Does homeowner insurance pay for termite damage?
Usually not. Most policies treat termite damage as preventable. That's why catching it early matters.
What does a termite warranty cover?
It depends on the plan. Some cover re-treatment only. Others also cover repairs. Ask what's excluded, and whether it transfers if you sell.
Is a bait system cheaper than a liquid treatment?
Not usually upfront. For Missoula homes, bait costs about the same to install, plus a yearly monitoring fee. A liquid barrier has no monthly checks. Ask for both prices.
How long does termite treatment take?
A liquid barrier takes half a day to a day. Bait stations take a few hours to install. Fumigation takes two to three days.
What is the difference between subterranean and drywood termites?
Subterranean termites live in soil and build mud tubes. Drywood termites live inside the wood and leave tiny pellets. Around Missoula, the subterranean kind causes most problems.
Do I need a termite inspection when buying a house?
Usually, yes. Many lenders ask for a wood-destroying insect (WDI) report. Either way, it's cheap peace of mind. Ask your agent when it's due.
Do most pest control companies treat existing homes for termites?
For Missoula homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Missoula 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 Missoula, the usual culprit is the arid-land subterranean termite.
