The short version
Most termite problems in Kailua 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.

Homeowners, landlords and anyone buying or selling a house in Kailua, 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 Kailua stay mild, with average lows near 68°F, so colonies keep feeding all year.

- 2Mud in cracks of subfloor or joists.
- 3Doors and windows that suddenly stick.
- 4Layered, honeycombed wood packed with soil.
- 5Small kick-out holes in exposed wood.
- 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.
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
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A soil barrier stops termites from reaching wood through the ground. For most Kailua homes with active subterranean termites, this is the fastest way to end feeding.
- 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
For new decks, additions, or repairs in Kailua, 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
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year
Baiting is slower than a liquid barrier but reaches deeper colonies. For a Kailua home on a well or with a finished slab, it is often the cleaner option.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
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 Kailua.
Drywood termites are common around Kailua as well, flying straight into attic framing, eaves and furniture without any soil contact. Look for tiny piles of pellets that look like coarse sand. The termite you're most likely to meet in Kailua 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 Hawaii too. They arrived through Gulf Coast ports. Their colonies are much bigger than native ones. They can do more damage, faster.
Local termites conditions in Kailua.
Knowing Kailua'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 Kailua and Hawaii 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. Kailua sits in a tropical climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. In Kailua, the area is mostly suburban, 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 Kailua usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.When termites swarm here.
Swarm season is when termites show themselves. In Kailua, eastern subterranean termites usually swarm from February through April, typically on a warm, sunny day after rain. Formosan termites in Hawaii 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.
Where to look around your house.
Many homes in Kailua 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. The same advice applies across the area, from Kailua out to Kaneohe and Honolulu.
A year of termites in Kailua.
- Summer: with highs around 85°F in Kailua, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 33 inches of rain a year in Kailua, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Kailua, before swarm season starts. - Spring: swarm season. In Kailua, 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?
- 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. - Waist: termites are thick through the middle. Ants are pinched.
Getting ready for treatment day.
Clear a path along the outside walls. Move stored boxes away from garage walls. 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.
Mulch and termites.
Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes.
Questions to ask before you sign.
- 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 product or system will you use?
What affects the price
- Whole-house fumigation versus spot treatment.
- Cubic footage under the tent for fumigation.
- Amount of drilling through concrete and patios.
- Slab, crawl space, or basement construction.
- Wells, drains, or water features limiting chemical use.
- Extent of existing damage needing repair.

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
- Extend downspouts so water drains away from walls.
- Seal cracks in the foundation and slab.
- Trim shrubs so foundation walls stay visible and dry.
- Install a vapor barrier over crawl space soil.
- Grade soil to slope away from the foundation.
- Remove tree stumps and buried wood near the house.
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?
In Kailua, when danger shows up, soldier termites bang their heads against the tunnel walls to warn the colony.
In Kailua, a termite queen can keep laying eggs for 25 years or more.
Questions people ask
How do I choose a termite company?
Ask what the warranty covers. Compare the proposals, not just the totals. Make sure they're licensed in Hawaii. Ask which termites they found and what product they'll use.
Is termite treatment safe for kids and pets?
Bait stations are locked and buried. Ask for the label and follow any re-entry times. Used according to the label, yes. Soil treatments stay in the ground.
What is the difference between subterranean and drywood termites?
Drywood termites live inside the wood and leave tiny pellets. Both turn up around Kailua. Subterranean termites live in soil and build mud tubes.
Can termites damage a house on a concrete slab?
They come up through expansion joints, plumbing gaps and small cracks. Most homes around Kailua sit on slabs, so inspectors check those spots first. Yes.
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.
How often does a termite treatment need a callback?
Rarely, according to the professionals themselves. For a homeowner, a 1.8% average callback rate, as professionals reported in PCT magazine's 2025 termite market report (about 145 pest-control professionals, 2024 operations), suggests return visits after termite treatment are uncommon.
Is termite prevention cheaper than repairing termite damage?
In Kailua, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Kailua, 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 Hawaii?
Around Kailua, the usual culprit is the eastern subterranean termite.
