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. Winters around Brownsville stay mild, with average lows near 52°F, so colonies keep feeding all year.

A slow leak under a sink keeps the wood damp, and damp wood is exactly what termites are looking for.How treatment works on a typical Brownsville home.
Under patios and garage floors, they drill small holes. Treatment goes in through the holes, which get patched afterward. Bait stations are the other main option. 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. For Brownsville homes, on a slab, the crew treats the soil along the outside walls.
Which termites live around Brownsville.
Their colonies dwarf native ones. Inspectors take them seriously. Drywood termites turn up now and then, mostly in older wood. Look for tiny piles of hard, sand-like pellets. The termite you're most likely to meet in Brownsville is the eastern subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture. Formosan termites have spread into parts of Texas too.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.When termites swarm here.
Drywood termites swarm on spring and summer evenings, often near 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 Brownsville homes, eastern subterranean termites usually swarm from February through April, typically on a warm, sunny day after rain. Formosan termites in Texas swarm later, from late April into June. Look for them on warm, humid evenings around porch lights.
Where to look around your house.
Many homes in Brownsville 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. Outside, watch for mud tubes behind shrubs. Keep soil and mulch below the slab edge.

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?
- 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. - Antennae: termite antennae are straight. Ant antennae bend like an elbow.
Getting ready for treatment day.
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. Clear a path along the outside walls. Move stored boxes away from garage walls. Mark sprinkler heads and any buried lines.
Mulch and termites.
Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like.

What affects the price
- Annual renewal and monitoring fees.
- Time of year and how booked up local companies are.

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 Brownsville
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.

Simple ways to keep termites away
- Ventilate crawl spaces and control humidity.
- Repair rotting trim, fascia, and window frames.
- Extend downspouts so water drains away from walls.
- Keep gutters clean so water does not pool.
- Remove tree stumps and buried wood near the house.
- Keep the termite renewal contract current after treatment.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?

Questions people ask
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.
What does a WDI report include?
It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach. It lists any termites or damage found.
How long does termite treatment take?
Bait stations take a few hours to install. Fumigation takes two to three days. A liquid barrier takes half a day to a day.
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.
Do I have to leave my house during termite treatment?
Fumigation is different. Everyone leaves for two to three days, pets and houseplants included. Not for a soil treatment or bait stations.
How much does termite treatment cost?
For Brownsville homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Brownsville homes, 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 Brownsville, the usual culprit is the eastern subterranean termite.
