Homeowners, landlords and anyone buying or selling a house in Lafayette, whether you've spotted something or just want to know what to watch for.
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 Lafayette stay mild, with average lows near 45°F, so colonies keep feeding all year.
- 1Dry hexagonal pellets under window frames or eaves.
- 2Small kick-out holes in exposed wood.
- 3Piles of identical shed wings on windowsills.
- 4Buckling laminate or warped hardwood flooring.
- 5Screwdriver sinks easily into sills or trim.
- 6Mud tubes running up foundation walls or piers.
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.
📅
Termite activity through the year in Lafayette
Spring
swarm season. Across Lafayette, expect it from February through April. Check windowsills and light fixtures for wings.
Summer
with highs around 92°F in Lafayette, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
Fall
with about 62 inches of rain a year in Lafayette, make sure gutters and downspouts carry water well away from the foundation.
Winter
a good time to book an inspection in Lafayette, before swarm season starts.
Treatment options and typical costs
Termite Inspection and WDI Report
$75–$250
The inspector checks the foundation, garage, attic and damp spots. Bring up anything you’ve noticed.
- Time
- 60–120 minutes
- Best for
- Every job, real estate closings, and yearly peace of mind
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year
Each station holds cellulose bait laced with a chitin synthesis inhibitor. Workers around a Lafayette home share it, cannot molt, and the colony dies over weeks to months.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A liquid barrier treatment around a Lafayette home means trenching and rodding termiticide into the soil along the foundation. Non-repellent products let termites pass through and carry the chemical home to the colony under Lafayette.
- Time
- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation
Localized Wood, Foam, and Borate Treatment
$250–$1,500
Spot treatment works when the Lafayette inspector can see and reach the whole infestation. Small drywood galleries, porch posts, and exposed sills are typical targets.
- Time
- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Prices are typical published ranges. Ask what’s included before you compare quotes.
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 Lafayette home.
The stations are checked on a schedule, often every few months. Across Lafayette, on a slab, the crew treats the soil along the outside walls. 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.
Which termites live around Lafayette.
Look for tiny piles of hard, sand-like pellets. The termite you're most likely to meet in Lafayette is the eastern subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture. Formosan termites are established in Louisiana too. They arrived through Gulf Coast ports. Their colonies are much bigger than native ones. They can do more damage, faster. Drywood termites turn up now and then, mostly in older wood.
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.
Across Lafayette, eastern subterranean termites usually swarm from February through April, typically on a warm, sunny day after rain. Formosan termites in Louisiana swarm later, from late April into June. Look for them on warm, humid evenings around porch lights. 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.
Where to look around your house.
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. The same advice applies across the area, from Lafayette out to New Iberia. Many homes in Lafayette sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks.
A year of termites in Lafayette.
- Spring: swarm season. Across Lafayette, expect it from February through April. Check windowsills and light fixtures for wings. - Summer: with highs around 92°F in Lafayette, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 62 inches of rain a year in Lafayette, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Lafayette, before swarm season starts.
What happens at an inspection.
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. 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.
Keep kids and pets inside while the Lafayette crew applies the product, and ask how long to stay off treated soil. In Louisiana, formosan swarms in the Gulf South occur in evenings from April to July (FDACS); native Reticulitermes swarm in late winter and spring (UGA). Drill holes in slabs or patios get patched afterward. 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.
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, and with roughly 62 inches of rain a year in Lafayette, keeping that strip dry takes real grading and gutter work. Wood chips touching the siding trap the moisture termites are after.
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
- Slab, crawl space, or basement construction.
- Time of year and how booked up local companies are.
- Wells, drains, or water features limiting chemical use.
- Whole-house fumigation versus spot treatment.
- Cubic footage under the tent for fumigation.
- Warranty type: retreatment only or damage repair.

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
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.

Simple ways to keep termites away
- Keep gutters clean so water does not pool.
- Trim shrubs so foundation walls stay visible and dry.
- Screen attic and foundation vents with fine mesh.
- Paint or seal exposed exterior wood.
- Never leave form boards or scrap lumber in the soil.
A damp cabinet under a leaky sink is worth reporting to your landlord early. Fixing the leak removes what draws termites in.Did you know?

Questions people ask
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.
Can termites damage a house on a concrete slab?
They come up through expansion joints, plumbing gaps and small cracks. Most homes around Lafayette sit on slabs, so inspectors check those spots first. Yes.
Are mud tubes always a sign of active termites?
Break off a piece and check back in a week. If it's rebuilt, they're active. Not always. Old tubes can stay on a wall for years.
Will termites come back after treatment?
Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for. They can.
How much does termite treatment cost?
Across Lafayette, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Lafayette, 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 Louisiana?
Around Lafayette, the usual culprit is the eastern subterranean termite.
