Homeowners, landlords and anyone buying or selling a house in Great Falls, 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 Great Falls average near 13°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.

Local termites conditions in Great Falls.
Across Great Falls, the area is mostly suburban, 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 Great Falls usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Great Falls'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 Great Falls 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. Great Falls sits in a semi-arid continental climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.Which termites live around Great Falls.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in Great Falls is the arid-land subterranean termite.
When termites swarm here.
Across Great Falls, 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. Swarm season is when termites show themselves.
Where to look around your house.
Look around window wells and unfinished walls. Outside, check porches, steps and decks that touch soil. Wood should stay several inches above the ground. Plenty of homes in Great Falls have basements, so check where the wood framing sits on top of the foundation wall.
A year of termites in Great Falls.
- Spring: swarm season in Great Falls, often on a warm day after rain. Check windowsills for wings. - Winter: a good time to book an inspection in Great Falls, before swarm season starts. - Fall: with about 14 inches of rain a year in Great Falls, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 85°F in Great Falls, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
Ways to keep the cost down.
- Book before swarm season, when schedules fill up. - Get two or three quotes, and compare what each one covers. - 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.
What happens at an inspection.
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. Photos help.
Termites or ants?
- 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. - 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.
Getting ready for treatment day.
Keep kids and pets inside while the Great Falls crew applies the product, and ask how long to stay off treated soil. Around Great Falls, swarms usually show up in April and May, later than in the South. Flag sprinkler heads and buried lines. Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations. Drill holes in slabs or patios get patched afterward.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Great Falls's dry climate the risk is irrigation and leaky hose bibs rather than rain. Pull mulch back from the foundation and keep the layer thin. Wood chips touching the siding trap the moisture termites are after.
Questions to ask before you sign.
- What do I need to do before and after treatment? - 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 affects the price
- Annual renewal and monitoring fees.
- Time of year and how booked up local companies are.
- Linear feet of foundation to be treated.
- Amount of drilling through concrete and patios.
- Whole-house fumigation versus spot treatment.
- Attached garages, decks, and additions.
- Slab, crawl space, or basement construction.
- Warranty type: retreatment only or damage repair.

What's your biggest concern about termite control costs?
When to call for help
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. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
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.
