Anyone in Lehi who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs. Termites work quietly. A colony can feed inside a wall for years. Winter lows around Lehi average near 22°F, so termites retreat deeper into the soil, though colonies under heated basements can stay active all winter.

Why it’s worth acting soon

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 Lehi 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 Lehi.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in Lehi 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 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. In Lehi, 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.
Where to look around your house.
Wood should stay several inches above the ground. The same advice applies across the area, from Lehi out to Orem and South Jordan. Plenty of homes in Lehi 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.
A year of termites in Lehi.
- Summer: with highs around 93°F in Lehi, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 16 inches of rain a year in Lehi, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Lehi, before swarm season starts. - Spring: swarm season in Lehi, 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?
- 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. - Waist: termites are thick through the middle. Ants are pinched.
Getting ready for treatment day.
Clear a path along the outside walls. Move stored boxes away from garage walls. 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.
Mulch and termites.
Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes.
Questions to ask before you sign.
- 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 product or system will you use?
What affects the price
- Slab, crawl space, or basement construction.
- Time of year and how booked up local companies are.
- Wells, drains, or water features limiting chemical use.
- Species: subterranean, drywood, or Formosan.
- Warranty type: retreatment only or damage repair.
- Number of bait stations required.

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 Lehi
A typical home in Lehi is worth around $565k, which puts a few hundred dollars for an inspection and prevention in perspective. Lehi has a semi-arid continental climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. In Lehi, 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. In Lehi, 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 Lehi and Utah can point out the specific conditions that matter most here before you commit to a plan. Lehi only sees about 16 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 93°F, Lehi's semi-arid continental climate decides when local termites are busiest.

Simple ways to keep termites away

- Screen attic and foundation vents with fine mesh.
- Keep the termite renewal contract current after treatment.
- Ventilate crawl spaces and control humidity.

Questions people ask
Will termites come back after treatment?
Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for. They can.
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
How do I choose a termite company?
Ask what the warranty covers. Compare the proposals, not just the totals. Make sure they're licensed in Utah. Ask which termites they found and what product they'll use.
Do I need a termite inspection when buying a house?
Either way, it's cheap peace of mind. Ask your agent when it's due. Usually, yes. Many lenders ask for a wood-destroying insect (WDI) report.
How do I know if I have termites or flying ants?
Ants have a pinched waist; termites don't. Save one in a bag for the inspector. Check the wings and the waist. Termite wings are all the same length.
How much does a pre-construction termite treatment cost?
In Lehi, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Lehi, 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 Lehi, the usual culprit is the arid-land subterranean termite.
