Structural Pest Control
Termite Control in San Leandro, CA
101 Exterminators does termite control in San Leandro as a California-licensed structural pest company — SPCB Lic. #9119. Most of this city went up between 1940 and 1965, and the block decides the pest. Raised-foundation homes down near San Leandro Creek get subterranean termites. The warmer foothill lots above Estudillo Avenue get drywood. We inspect first, then report by section.
Home maintenance
How do you keep termites out of a San Leandro home?
Keep wood dry and keep it off the soil. San Leandro has both kinds: subterranean colonies forage up from damp ground on the Bay flats and along San Leandro Creek, and drywood termites fly into the eaves of the post-war tracts from August into October. Prevention here comes down to drainage, clearance and a yearly look at exposed wood.
Clear gutters before the winter rain
San Leandro gets nearly all of its 18 to 20 inches of rain in the winter months. Clean gutters in fall and point downspouts away from the house, so the first storms don’t soak the soil against the walls where subterranean termites forage.
Lower soil and bark below the siding
Planter beds in Washington Manor and Broadmoor have had decades to creep up the stucco and wood siding. Pull soil and mulch down so no siding, trim or fence post touches the ground, and leave a strip along the wall you can see.
Aim sprinklers away from the walls
Dry summers mean months of irrigation. Point heads away from the house and fix leaking drip emitters in the beds along the foundation, because damp soil against the wall gives subterranean colonies the moisture they follow upward.
Check eaves from August to October
Drywood termites swarm in late summer and fall and land on the wide overhangs and rafter tails of homes built between 1940 and 1965. Walk the eave line once in that window and look for small six-sided pellets on sills and the ground below.
Seal and paint exposed wood
Swarmers get into framing through cracks and bare wood. Keep fascia, rafter tails and window trim painted, caulk open joints, and replace torn attic and gable vent screens so winged termites have fewer ways in.
When to do it
Gutters and grading in October, before the winter rain; an eave-line pellet check between August and October.

Warning Signs
When to Ask About Termite Control in San Leandro
We check visible wood in accessible attics, crawl spaces, fences, and exterior areas, then explain the next step. For written findings needed in a sale, book a paid structural pest inspection. Its WDO report separates Section 1 from Section 2 conditions.
Hollow-sounding wood when tapped — galleries eaten from inside
Frass (fine sawdust-like pellets) near baseboards or windowsills — drywood termite excrement
Discarded wings near doors or windows in spring — swarmers leaving to start new colonies
Blistering or bubbling paint on wood surfaces — subterranean tunnel activity underneath
Mud tubes running up foundation walls or piers — subterranean termite foraging trails
Soft or sagging flooring near walls — severe structural damage to subfloor joists
Small holes in wood with discoloration around the edges

Common Questions
Termite Control FAQs for San Leandro
Does it matter if my San Leandro house is on a slab or over a crawl space?
Yes — it changes which termite you are likely to have and how an exterminator finds it. Raised-foundation homes show subterranean mud tubes on pier blocks and stem walls, so the sub-area is the first place we look. Slab homes hide that route, so subterranean activity turns up at the garage cold joint, at plumbing penetrations, or as damage inside a wall with no exterior sign at all. San Leandro has plenty of both, sometimes on the same block.
I found small wings on a windowsill in my Bay-O-Vista home — are those termites?
Discarded wings on a sill or in a light fixture usually mean a swarm, and the timing tells you which kind. Western drywood termites fly on warm evenings from August into October, which is why a Bay-O-Vista windowsill above the fog line tends to collect them late in the year. Subterranean swarms follow the winter rains instead. Save a few wings in a bag, because identification changes the treatment completely.
Are the pre-war houses around Old San Leandro at higher termite risk than the post-war tracts?
They carry a different risk, not automatically a higher one. The Craftsman, Italianate and Colonial Revival homes in the older core sit on raised foundations with real crawl spaces, so we find subterranean tubes and sub-area decay there more often. The 1950s and 1960s tracts across Washington Manor and Floresta Gardens have wide eaves, exposed rafter tails and more than 60 years of drywood exposure. Both need the same inspection. The findings just land in different sections.
