Homeowners, landlords and anyone buying or selling a house in San Angelo, whether you've spotted something or just want to know what to watch for.
What to look for
A colony can feed inside a wall for years. Termites work quietly. So it's worth an inspection, even for one or two signs. Spongy floors or bubbling paint usually mean long-running damage. Cool winters slow them near the surface, not underground.
- 1Layered, honeycombed wood packed with soil.
- 2Wood that sounds hollow when tapped.
- 3Discarded wings caught in spider webs.
- 4Dry hexagonal pellets under window frames or eaves.
- 5Sagging or spongy floors near exterior walls.
- 6Termite activity reported at a neighbor's home.
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.
- Formosan colonies are large and can do serious damage quickly.

Local termites conditions in San Angelo.
An inspection in San Angelo usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around San Angelo, the area is mostly residential, 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. San Angelo sits in a local climate, and that sets the pace for termite activity here: the warmer months. A provider who works San Angelo and Texas 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. Knowing San Angelo'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.
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.
A swarm outside means a colony is nearby. Look for them on warm, humid evenings around porch lights. Formosan termites in Texas swarm later, from late April into June. Around San Angelo, eastern subterranean termites usually swarm from March through May, typically on a warm, sunny day after rain. Swarm season is when termites show themselves. Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house.
Where to look around your house.
Look where pipes come through the floor. Check the garage edges and behind baseboards. Many homes in San Angelo sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks. Keep soil and mulch below the slab edge. Outside, watch for mud tubes behind shrubs.
A year of termites in San Angelo.
- Spring: swarm season. Around San Angelo, expect it from March through May. Check windowsills and light fixtures for wings. - Winter: a good time to book an inspection in San Angelo, before swarm season starts. - Fall: clear gutters and move firewood away from the walls. - Summer: termites follow moisture. Watch AC lines, sprinklers and hose bibs.
What happens at an inspection.
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. Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. On a slab, they focus on joints, cracks and pipe gaps.
Termites or ants?
- Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Debris: termites leave mud. Carpenter ants leave sawdust. - Antennae: termite antennae are straight. Ant antennae bend like an elbow.
Getting ready for treatment day.
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. Keep kids and pets inside while the Texas crew applies the product, and ask how long to stay off treated soil. In Texas, swarms begin in January–February in South Texas and not until April or May in the Panhandle (Texas A&M). Flag sprinkler heads and buried lines.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Texas that means extending downspouts and pulling mulch back from the slab. 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 product or system will you use? - Which termites did you find, and where? - What do I need to do before and after treatment? - What does the yearly renewal cost? - What does the warranty cover, and for how long? - Is the whole foundation treated, or just one spot?
What affects the price
- Number of bait stations required.
- Time of year and how booked up local companies are.
- Slab, crawl space, or basement construction.
- Wells, drains, or water features limiting chemical use.
- Amount of drilling through concrete and patios.
- Access to crawl spaces and attics.

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
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.

When termites are busiest around San Angelo
Swarms begin in January–February in South Texas and not until April or May in the Panhandle (Texas A&M).
Texas A&M identifies the eastern subterranean and Formosan subterranean termites as the two economically important species. Termites enter via wood in direct contact with soil and by building shelter tubes over or through foundation cracks; modern termiticides provide approximately 5 years of protection and licensed professionals are recommended.
