Tigard sits in a mediterranean climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south.

When termites swarm here.
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. In Tigard, western subterranean termites usually swarm in spring, and again in fall after the first good rain. A swarm outside means a colony is nearby.

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.

What affects the price
- Warranty type: retreatment only or damage repair.
- Access to crawl spaces and attics.
- Cubic footage under the tent for fumigation.
- Amount of drilling through concrete and patios.
- Liquid barrier versus bait station system.
- Wells, drains, or water features limiting chemical use.

What's your biggest concern about termite control costs?
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.
