Structural Pest Control
Termite Control in Gilroy, CA
101 Exterminators does termite control in Gilroy as a California-licensed structural pest company — SPCB Lic. #9119, working South Santa Clara County since 2005. Subterranean termites swarm here from February into April, once winter rain and a fast warm-up meet in the soil. The 1970s–2000s slab tracts and the pre-1930s framing downtown fail in different ways, so we inspect for both and put the findings in writing.
Warning Signs
Signs You Need Termites Service in Gilroy
We perform thorough visual inspections of all accessible structural wood, attic spaces, crawl spaces, fencing, and exterior wood. Our reports clearly distinguish Section 1 conditions (active infestations requiring immediate treatment) from Section 2 conditions (conditions that are likely to lead to infestation). We issue California-required WDO reports for real estate transactions and carry the licensing required by the Structural Pest Control Board.
Hollow-sounding wood when tapped — galleries eaten from inside
Frass (fine sawdust-like pellets) near baseboards or windowsills — drywood termite excrement

Common Questions
Termite Control FAQs for Gilroy
When do termites swarm in Gilroy?
Subterranean termite swarms in Gilroy usually come between February and April, within days of a warm stretch following winter rain. You may see hundreds of winged insects leaving a foundation crack, a slab joint, or a crawl-space vent, then shedding wings on a windowsill or in a pool. Swarmers do not chew wood — they are proof that a mature colony is already established under or beside the structure. Save a few in a bag; species identification decides the treatment.
Can a newer house in Glen Loma Ranch or Eagle Ridge still get termites?
Yes. A recent build slows drywood termites down, not subterranean ones. Newer Gilroy construction is slab-on-grade with landscape irrigation running right against the foundation, which holds soil moisture exactly where Reticulitermes wants it. The insects then reach framing through slab cracks, expansion joints, and plumbing penetrations. On those streets we check the stem wall, the garage sill, and where the sprinkler heads are aimed before anything else.
What are the mud tubes on my Gilroy foundation wall?
Those are shelter tubes, and they mean subterranean termites are traveling from the soil to the wood in your house. They are about pencil width, built from soil and saliva, and usually run up a stem wall, a pier, or the inside face of a garage foundation. Breaking a short section open shows whether workers are still using it, but an empty tube does not mean the colony is gone — it often just means they rerouted. Leave the rest intact so an inspector can trace the path.
