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.

Local termites conditions in St. George.
St. George sits in a hot desert climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. In St. George, 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 St. George usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing St. George'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 St. George and Utah 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.
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 St. George.
The termite you're most likely to meet in St. George is the arid-land subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture.
When termites swarm here.
Swarm season is when termites show themselves. In 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.
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 St. George 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 St. George.
- Summer: with highs around 102°F in St. George, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 8 inches of rain a year in St. George, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in St. George, before swarm season starts. - Spring: swarm season in St. George, often on a warm day after rain. Check windowsills for wings.
Ways to keep the cost down.
- 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. - Fix leaks and drainage first. Moisture brings termites back.
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
- Annual renewal and monitoring fees.
- Access to crawl spaces and attics.
- Warranty type: retreatment only or damage repair.
- Whole-house fumigation versus spot treatment.
- Extent of existing damage needing repair.
- Amount of drilling through concrete and patios.
- Linear feet of foundation to be treated.
- Slab, crawl space, or basement construction.

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
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.
