The short version
Most termite problems in New Orleans are eastern subterranean termites, and the usual fix is a liquid soil treatment or bait stations. Drywood termites need fumigation or wood treatment instead. Start with an inspection; $75–$250 is typical.
- Look for mud tubes, shed wings and hollow-sounding wood.
- Swarms usually show up from February through April.
- Drywood termites need wood treatment or fumigation instead.
- An inspection typically costs $75–$250.
- Insurance usually doesn’t cover termite damage.
Anyone in New Orleans who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Winters around New Orleans stay mild, with average lows near 45°F, so colonies keep feeding all year. 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.
- 2Dry hexagonal pellets under window frames or eaves.
- 3Termite activity reported at a neighbor's home.
- 4Discarded wings caught in spider webs.
- 5Crumbling baseboards behind furniture.
- 6Layered, honeycombed wood packed with soil.
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

- 60–120 minutes
- Best for
- Every job, real estate closings, and yearly peace of mind
Annual Renewal and Monitoring
$150–$400 per year
Termites do not stop foraging after a treatment, so monitoring matters. Yearly visits to a New Orleans home catch new tubes before they reach framing.
- Time
- 30–60 minutes per visit
- Best for
- Keeping a treated home protected after the initial job
Localized Wood, Foam, and Borate Treatment
$250–$1,500
A local treatment is cheaper than fumigation but only covers what the New Orleans technician can find. Hidden drywood galleries elsewhere in the house are not touched.
- Time
- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year

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 Orleans.
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 Orleans 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.
Local termites conditions in New Orleans.
An inspection in New Orleans 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 Orleans'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 Orleans 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. New Orleans 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 Orleans homes, the area is mostly urban, 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.
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 New Orleans 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 Orleans out to Gretna and Kenner. Many homes in New Orleans 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 Orleans.
- Summer: with highs around 91°F in New Orleans, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 64 inches of rain a year in New Orleans, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in New Orleans, before swarm season starts. - Spring: swarm season. For New Orleans homes, expect it from February through April. Check windowsills and light fixtures for wings.
What happens at an inspection.
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. 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.
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. 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.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation.
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
- Warranty type: retreatment only or damage repair.
- Whole-house fumigation versus spot treatment.
- Slab, crawl space, or basement construction.
- Local labor rates and licensing requirements.
- Liquid barrier versus bait station system.
- 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.

Simple ways to keep termites away
- Set deck and porch posts on concrete, not soil.
- Install a vapor barrier over crawl space soil.
- Check the foundation for mud tubes every spring.
- Seal cracks in the foundation and slab.
- Inspect used furniture for drywood pellets before bringing indoors.
- Grade soil to slope away from the foundation.
An inspection starts outside, with a flashlight along the foundation line where mud tubes show up first.Did you know?
For New Orleans homes, termites are closer cousins to cockroaches than to ants, despite the old nickname white ants.
For New Orleans homes, soldier termites can't feed themselves, so the workers feed them mouth to mouth.
Questions people ask
Can I treat termites myself?
Prevention, yes. An active colony is harder. The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see.
How do I choose a termite company?
Make sure they're licensed in Louisiana. Ask which termites they found and what product they'll use. Ask what the warranty covers. Compare the proposals, not just the totals.
Will termites come back after treatment?
They can. Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for.
Can termites damage a house on a concrete slab?
Yes. They come up through expansion joints, plumbing gaps and small cracks. Most homes around New Orleans sit on slabs, so inspectors check those spots first.
When is termite swarming season?
For New Orleans homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For New Orleans 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 Orleans, the usual culprit is the eastern subterranean termite.
