Homeowners, landlords and anyone buying or selling a house in New Iberia, 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 New Iberia stay mild, with average lows near 46°F, so colonies keep feeding all year.
- 1Mud in cracks of subfloor or joists.
- 2Small kick-out holes in exposed wood.
- 3Crumbling baseboards behind furniture.
- 4Live pale insects inside a broken mud tube.
- 5Screwdriver sinks easily into sills or trim.
- 6Wood that sounds hollow when tapped.
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.
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
Bait systems around New Iberia homes need ongoing monitoring to keep working. Skip the yearly service and the stations go unchecked.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Localized Wood, Foam, and Borate Treatment
$250–$1,500
For new decks, additions, or repairs in New Iberia, borate on the framing is cheap insurance. Ask to have the wood treated before it's closed in.
- Time
- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Fumigation for Drywood Termites
$1,200–$4,000 (often $1–$4 per square foot)
Tenting is thorough but leaves no residual protection behind. New drywood swarmers can land on a New Iberia home the following season, so follow-up inspections still matter.
- Time
- 2–3 days including tenting and aeration
- Best for
- Widespread drywood termites throughout a structure
Prices are typical published ranges. Ask what’s included before you compare quotes.
Drywood termites can fly straight into attic framing through vents, so attics belong on the inspection list in warm climates.Which termites live around New Iberia.
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. Look for tiny piles of hard, sand-like pellets. The termite you're most likely to meet in New Iberia is the eastern subterranean termite. It nests in soil and builds mud tubes to reach wood.
Local termites conditions in New Iberia.
New Iberia sits in a humid subtropical climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. For New Iberia homes, the area is mostly rural, 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. An inspection in New Iberia usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing New Iberia'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 New Iberia and Louisiana 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.
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.
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 New Iberia homes, 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.
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 New Iberia out to Lafayette. Many homes in New Iberia 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 New Iberia.
- Fall: with about 61 inches of rain a year in New Iberia, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in New Iberia, before swarm season starts. - Spring: swarm season. For New Iberia homes, expect it from February through April. Check windowsills and light fixtures for wings. - Summer: with highs around 92°F in New Iberia, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
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.
Questions to ask before you sign.
- 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 product or system will you use? - Is the whole foundation treated, or just one spot?
What affects the price
- Amount of drilling through concrete and patios.
- Species: subterranean, drywood, or Formosan.
- Attached garages, decks, and additions.
- Access to crawl spaces and attics.
- Liquid barrier versus bait station system.
- Number of bait stations required.

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
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 New Iberia
Formosan swarms in the Gulf South occur in evenings from April to July (FDACS); native Reticulitermes swarm in late winter and spring (UGA).
FDACS and UGA both list Louisiana among states where the Formosan subterranean termite is established. (LSU AgCenter pages could not be fetched this session; Louisiana-specific figures are not recorded.)

Simple ways to keep termites away
- Trim shrubs so foundation walls stay visible and dry.
- Repair rotting trim, fascia, and window frames.
- Keep the termite renewal contract current after treatment.
- Store firewood well away from the house, off the ground.
- Address wood-to-soil contact at steps, fences, and trellises.
- Keep gutters clean so water does not pool.
A liquid soil treatment goes into a trench along the foundation so termites cross it on their way to the house.Did you know?
Some African termite mounds stand more than 25 feet tall.
For New Iberia homes, termites are closer cousins to cockroaches than to ants, despite the old nickname white ants.
Questions people ask
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.
Can I treat termites myself?
The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see. Prevention, yes. An active colony is harder.
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.
Can termites damage a house on a concrete slab?
They come up through expansion joints, plumbing gaps and small cracks. Most homes around New Iberia sit on slabs, so inspectors check those spots first. Yes.
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.
Are termite baits or liquid treatments more common?
For New Iberia homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For New Iberia 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 Louisiana?
Around New Iberia, the usual culprit is the eastern subterranean termite.
