Homeowners, landlords and anyone buying or selling a house in Denton, whether you've spotted something or just want to know what to watch for.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 34°F slow termites near the surface around Denton, 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.
- 1Blistered or bubbling paint on wood surfaces.
- 2Damage found during a remodel or repair.
- 3Wood that sounds hollow when tapped.
- 4Doors and windows that suddenly stick.
- 5Crumbling baseboards behind furniture.
- 6Live pale insects inside a broken mud tube.
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.

Check under the kitchen sink for dampness and soft cabinet wood. Plumbing walls are a common path for termites coming up from a slab.How treatment works on a typical Denton home.
The stations are checked on a schedule, often every few months. Termites carry the bait back to the colony. They're spaced every 10 to 20 feet. Bait stations are the other main option. Treatment goes in through the holes, which get patched afterward. Under patios and garage floors, they drill small holes. Around Denton, on a slab, the crew treats the soil along the outside walls.
Which termites live around Denton.
It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in Denton is the eastern subterranean termite.
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.
Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house. A swarm outside means a colony is nearby. Around Denton, eastern subterranean termites usually swarm from March through May, typically on a warm, sunny day after rain. Swarm season is when termites show themselves.
Where to look around your house.
The same advice applies across the area, from Denton out to Frisco and Carrollton. Keep soil and mulch below the slab edge. Outside, watch for mud tubes behind shrubs. Look where pipes come through the floor. Check the garage edges and behind baseboards. Many homes in Denton sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks.
A year of termites in Denton.
- Spring: swarm season. Around Denton, expect it from March through May. Check windowsills and light fixtures for wings. - Summer: with highs around 96°F in Denton, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 38 inches of rain a year in Denton, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Denton, before swarm season starts.
What happens at an inspection.
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. On a slab, they focus on joints, cracks and pipe gaps. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help.
Termites or ants?
- 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. - Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
Prep is light for liquid treatments and bait stations. 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 Denton 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). Drill holes in slabs or patios get patched afterward.
Mulch and termites.
Pull mulch back from the foundation and keep the layer thin. A dry gap along the house makes mud tubes easier to spot; in Denton that means extending downspouts and pulling mulch back from the slab. Wood chips touching the siding trap the moisture termites are after.
Questions to ask before you sign.
- 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 product or system will you use? - Which termites did you find, and where?
What affects the price
- Warranty type: retreatment only or damage repair.
- Linear feet of foundation to be treated.
- Extent of existing damage needing repair.
- Liquid barrier versus bait station system.
- Time of year and how booked up local companies are.
- Wells, drains, or water features limiting chemical use.

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 Denton
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.

- Screen attic and foundation vents with fine mesh.
- Keep mulch at least a foot from the foundation.

Questions people ask
Can I treat termites myself?
Store-bought sprays usually kill only what you see. It also needs even coverage around the foundation. The product must reach the whole colony. An active colony is harder. Prevention, yes.
What does a WDI report include?
It only covers areas the inspector could reach. It also notes conditions that invite them, like wood touching soil. It lists any termites or damage found.
Does fumigation kill subterranean termites too?
It doesn't reach a colony living in the soil. Tenting clears termites inside the house. Not reliably.
How long does termite treatment take?
Fumigation takes two to three days. Bait stations take a few hours to install. A liquid barrier takes half a day to a day.
What is the difference between subterranean and drywood termites?
Around Denton, the subterranean kind causes most problems. Drywood termites live inside the wood and leave tiny pellets. Subterranean termites live in soil and build mud tubes.
When is termite swarming season?
Around Denton, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Denton, 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 Texas?
Around Denton, the usual culprit is the eastern subterranean termite.
