What to look for
Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 36°F slow termites near the surface around Lewisville, 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.
- 1Crumbling baseboards behind furniture.
- 2Damage found during a remodel or repair.
- 3Small kick-out holes in exposed wood.
- 4Termite tubes hanging down from ceilings or joists.
- 5Buckling laminate or warped hardwood flooring.
- 6Tiny pinholes in drywall rimmed with mud.
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 Lewisville.
An inspection in Lewisville usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Lewisville'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 Lewisville 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. Lewisville sits in a local climate, and that sets the pace for termite activity here: the warmer months. For Lewisville homes, 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.
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.
Look for them on warm, humid evenings around porch lights. 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. For Lewisville homes, eastern subterranean termites usually swarm from March through May, typically on a warm, sunny day after rain. Formosan termites in Texas swarm later, from late April into June.
Where to look around your house.
Outside, watch for mud tubes behind shrubs. Keep soil and mulch below the slab edge. The same advice applies across the area, from Lewisville out to Carrollton and Frisco. Many homes in Lewisville sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks. Check the garage edges and behind baseboards. Look where pipes come through the floor.
A year of termites in Lewisville.
- Fall: with about 38 inches of rain a year in Lewisville, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 96°F in Lewisville, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Spring: swarm season. For Lewisville homes, expect it from March through May. Check windowsills and light fixtures for wings. - Winter: a good time to book an inspection in Lewisville, before swarm season starts.
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. - 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.
Getting ready for treatment day.
Mark sprinkler heads and any buried lines. Move stored boxes away from garage walls. Clear a path along the outside walls. Soil treatments and bait stations need little prep. Any drill holes in a slab or patio get patched. Ask how long to stay off treated soil. Keep pets and kids inside while the crew works outside.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Keep mulch thin and pull it back from the foundation. Wood chips right against siding hold moisture termites like.
Questions to ask before you sign.
- 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 do I need to do before and after treatment? - Which termites did you find, and where?
What affects the price
- Extent of existing damage needing repair.
- Access to crawl spaces and attics.
- Annual renewal and monitoring fees.
- Local labor rates and licensing requirements.
- Amount of drilling through concrete and patios.
- Number of bait stations required.

What's your biggest concern about termites?
When to call for help
Termites leave mud. Carpenter ants leave clean tunnels and sawdust. It's also the cheapest termite service. Lenders often ask for one. Get a wood-destroying insect (WDI) report either way. Buying or selling? Hollow-sounding wood is another clue. Call if you see mud tubes, pellets or an indoor swarm.
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.

When termites are busiest around Lewisville
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.
