What to look for
Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 34°F slow termites near the surface around Grants Pass, but they move deeper and keep feeding under heated homes. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.

- 2Small kick-out holes in exposed wood.
- 3Piles of identical shed wings on windowsills.
- 4Screwdriver sinks easily into sills or trim.
- 5Discarded wings caught in spider webs.
- 6Crumbling baseboards behind furniture.
Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.

Local termites conditions in Grants Pass.
An inspection in Grants Pass usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Grants Pass'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 Grants Pass 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. Grants Pass sits in a mediterranean climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. For Grants Pass 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.
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.
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 Grants Pass homes, western subterranean termites usually swarm in spring, and again in fall after the first good rain.
Where to look around your house.
Check the piers, the sill plate and the floor joists. Standing water or a musty smell needs fixing either way. The same advice applies across the area, from Grants Pass out to Medford and Ashland. A lot of houses around Grants Pass are built over crawl spaces, and that's usually where termites start. Take a flashlight underneath.

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. - 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. Move stored boxes away from garage walls. Clear a path along the outside walls. Soil treatments and bait stations need little prep. Any drill holes in a slab or patio get patched. Ask how long to stay off treated soil. Keep pets and kids inside while the crew works outside.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Keep mulch thin and pull it back from the foundation. Wood chips right against siding hold moisture termites like.
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
- Access to crawl spaces and attics.
- Linear feet of foundation to be treated.
- Time of year and how booked up local companies are.
- Number of bait stations required.
- Cubic footage under the tent for fumigation.
- Liquid barrier versus bait station system.

What's your biggest concern about termites?
When to call for help
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. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
What you can do yourself
Store-bought sprays usually kill only the termites you see. It also needs even coverage around the entire foundation. The product has to reach the whole colony. Treating an active colony is harder. Keep firewood away from the house. Fix leaks and clear gutters. Pull mulch back from the foundation. Some of the work is yours.
