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. Average winter lows near 36°F slow termites near the surface around Hillsboro, but they move deeper and keep feeding under heated homes.
- 1Winged swarmers indoors, especially in spring.
- 2Tiny pinholes in drywall rimmed with mud.
- 3Small kick-out holes in exposed wood.
- 4Termite activity reported at a neighbor's home.
- 5Buckling laminate or warped hardwood flooring.
- 6Live pale insects inside a broken mud tube.
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.

Local termites conditions in Hillsboro.
An inspection in Hillsboro usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around Hillsboro, 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. Hillsboro sits in a mediterranean climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. A provider who works Hillsboro and Oregon 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. Knowing Hillsboro'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.
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.
A swarm outside means a colony is nearby. Around Hillsboro, western subterranean termites usually swarm in spring, and again in fall after the first good rain. Swarm season is when termites show themselves. Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house.
Where to look around your house.
Check the piers, the sill plate and the floor joists. Take a flashlight underneath. A lot of houses around Hillsboro are built over crawl spaces, and that's usually where termites start. The same advice applies across the area, from Hillsboro out to Beaverton and Tigard. Standing water or a musty smell needs fixing either way.
A year of termites in Hillsboro.
- Spring and fall: swarm seasons. Around Hillsboro, swarms often follow the first warm days and the first fall rain. - Winter: a good time to book an inspection in Hillsboro, before swarm season starts. - Fall: with about 38 inches of rain a year in Hillsboro, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 81°F in Hillsboro, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
What happens at an inspection.
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. Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. They'll also go into the crawl space.
Termites or ants?
- Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Debris: termites leave mud. Carpenter ants leave sawdust. - Antennae: termite antennae are straight. Ant antennae bend like an elbow.
Getting ready for treatment day.
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. Keep kids and pets inside while the Hillsboro crew applies the product, and ask how long to stay off treated soil. In Oregon, pacific dampwood swarms late summer or fall; western subterranean may swarm any time of year (Oregon State). Flag sprinkler heads and buried lines.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Hillsboro 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 product or system will you use? - Which termites did you find, and where? - What do I need to do before and after treatment? - What does the yearly renewal cost? - What does the warranty cover, and for how long? - Is the whole foundation treated, or just one spot?
What affects the price
- Attached garages, decks, and additions.
- Linear feet of foundation to be treated.
- Number of bait stations required.
- Warranty type: retreatment only or damage repair.
- Whole-house fumigation versus spot treatment.
- Time of year and how booked up local companies are.

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.

Questions people ask
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
Do I have to leave my house during termite treatment?
Fumigation is different. Everyone leaves for two to three days, pets and houseplants included. Not for a soil treatment or bait stations.
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.
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.
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.
When is termite swarming season?
Around Hillsboro, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Hillsboro, 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 Oregon?
Around Hillsboro, the usual culprit is the western subterranean termite.
