The short version

Most termite problems in Honolulu 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 Honolulu 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 Honolulu stay mild, with average lows near 66°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.

  • Sagging or spongy floors near exterior walls.
  • Wood that sounds hollow when tapped.
  • Termite activity reported at a neighbor's home.
  • Damage found during a remodel or repair.
  • Layered, honeycombed wood packed with soil.
  • Blistered or bubbling paint on wood surfaces.

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.

Which termites live around Honolulu.

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. Drywood termites are common around Honolulu 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 Honolulu is the eastern subterranean termite.

Local termites conditions in Honolulu.

Across Honolulu, 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. An inspection in Honolulu usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Honolulu'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 Honolulu 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. Honolulu sits in a tropical climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south.

When termites swarm here.

Across Honolulu, 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. 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 Honolulu out to Kaneohe and Pearl City. Many homes in Honolulu sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks.

A year of termites in Honolulu.

  • Spring: swarm season. Across Honolulu, expect it from February through April. Check windowsills and light fixtures for wings. - Winter: a good time to book an inspection in Honolulu, before swarm season starts. - Fall: with about 49 inches of rain a year in Honolulu, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 88°F in Honolulu, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.

What happens at an inspection.

Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. On a slab, they focus on joints, cracks and pipe gaps. Inside, they check the garage, baseboards, plumbing gaps and the attic. They check the foundation, the soil line and nearby wood. The inspector walks the outside of the house first. Most inspections take an hour or two. Photos help.

Termites or ants?

  • 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. - Debris: termites leave mud. Carpenter ants leave sawdust.

Getting ready for treatment day.

Keep kids and pets inside while the Honolulu crew applies the product, and ask how long to stay off treated soil. In Hawaii, formosan swarms occur in evenings April–July in the mainland South (FDACS); Hawaii-specific timing not verified this session. Flag sprinkler heads and buried lines. Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations. Drill holes in slabs or patios get patched afterward.

Mulch and termites.

A dry gap along the house makes mud tubes easier to spot; in Honolulu that means extending downspouts and pulling mulch back from the slab. Pull mulch back from the foundation and keep the layer thin. Wood chips touching the siding trap the moisture termites are after.

Questions to ask before you sign.

  • 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 does the warranty cover, and for how long? - What does the yearly renewal cost?

What affects the price

  • Cubic footage under the tent for fumigation.
  • Slab, crawl space, or basement construction.
  • Amount of drilling through concrete and patios.
  • Attached garages, decks, and additions.
  • Time of year and how booked up local companies are.
  • Whole-house fumigation versus spot treatment.

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.

Termites in Honolulu

A typical home in Honolulu is worth around $800k, which puts a few hundred dollars for an inspection and prevention in perspective. With summer highs around 88°F, Honolulu's tropical climate decides when local termites are busiest. An annual inspection is common sense here. Hawaii is one of the most termite-active states in the country. Honolulu gets about 49 inches of rain a year, and average humidity sits near 62%, so the soil around foundations rarely dries out.

Simple ways to keep termites away

  • Check the foundation for mud tubes every spring.
  • Address wood-to-soil contact at steps, fences, and trellises.
  • Set deck and porch posts on concrete, not soil.
  • Repair rotting trim, fascia, and window frames.
  • Ventilate crawl spaces and control humidity.
  • Trim shrubs so foundation walls stay visible and dry.

Questions people ask

Does fumigation kill subterranean termites too?

It doesn't reach a colony living in the soil. Tenting clears termites inside the house. Not reliably.

How long does termite treatment take?

Fumigation takes two to three days. Bait stations take a few hours to install. A liquid barrier takes half a day to a day.

How long do termite bait stations take to work?

Then the bait spreads through the colony. Termites have to find the stations first. Usually several weeks to a few months.

Is termite treatment safe for kids and pets?

Ask for the label and follow any re-entry times. Bait stations are locked and buried. Soil treatments stay in the ground. Used according to the label, yes.

Do I have to leave my house during termite treatment?

Everyone leaves for two to three days, pets and houseplants included. Fumigation is different. Not for a soil treatment or bait stations.

Are termite treatment prices going up?

Most professionals expected them to. A homeowner putting off a termite quote should know that 75% of professionals in Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 respondents) expected to raise prices in 2025.

What are the signs of termites that homeowners miss?

Across Honolulu, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Honolulu, 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 Honolulu, the usual culprit is the eastern subterranean termite.
