Anyone in St. George 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. Average winter lows near 31°F slow termites near the surface around St. George, but they move deeper and keep feeding under heated homes. 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.
- 2Buckling laminate or warped hardwood flooring.
- 3Damage found during a remodel or repair.
- 4Wood that sounds hollow when tapped.
- 5Piles of identical shed wings on windowsills.
- 6Doors and windows that suddenly stick.
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.

- Best for
- Every job, real estate closings, and yearly peace of mind
Annual Renewal and Monitoring
$150–$400 per year
Renewal fees are small next to a second full treatment. For St. George homeowners, the visit usually includes a walk-around, a crawl space check, and a bait station service.

Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year

- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A liquid barrier treatment around a St. George home means trenching and rodding termiticide into the soil along the foundation. Non-repellent products let termites pass through and carry the chemical home to the colony under St. George.
- Time
- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation
Prices are typical published ranges. Ask what’s included before you compare quotes.
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 St. George home.
Inside, they may drill where the floor meets the walls. Bait stations are the other main option. 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.
Which termites live around St. George.
George is the arid-land subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in St.
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.
Across St. George, 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.
George 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. Plenty of homes in St.

What happens at an inspection.
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. 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.
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.
Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines. Keep kids and pets inside while the St. George crew applies the product, and ask how long to stay off treated soil. In Utah, not specified by Utah State; western subterranean termites in the region may swarm any time of year (Oregon State). Drill holes in slabs or patios get patched afterward. Prep is light for liquid treatments and bait stations.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in St. George's dry climate the risk is irrigation and leaky hose bibs rather than rain. Wood chips touching the siding trap the moisture termites are after. Pull mulch back from the foundation and keep the layer thin.
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
- Wells, drains, or water features limiting chemical use.
- Linear feet of foundation to be treated.
- Species: subterranean, drywood, or Formosan.
- Local labor rates and licensing requirements.
- Attached garages, decks, and additions.
- Slab, crawl space, or basement construction.

What's your biggest concern about termites?
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.
Termites in St. George
St. George only sees about 8 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 Utah. Not every house gets them, but plenty do. With summer highs around 102°F, St. George's hot desert climate decides when local termites are busiest. A typical home in St. George is worth around $510k, which puts a few hundred dollars for an inspection and prevention in perspective. St. George has a hot desert climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. Across St. George, 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.

Questions people ask
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 St. George, the subterranean kind causes most problems.
Can termites damage a house on a concrete slab?
Yes. They come up through expansion joints, plumbing gaps and small cracks. Inspectors check those spots first.
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.
Does fumigation kill subterranean termites too?
Not reliably. Tenting clears termites inside the house. It doesn't reach a colony living in the soil.
Is termite prevention cheaper than repairing termite damage?
Across St. George, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across St. George, 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 Utah?
Around St. George, the usual culprit is the arid-land subterranean termite.
