Residential Pest Control in San Leandro, CA
101 Exterminators is a residential pest control company in San Leandro handling termites, rodents, ants, spiders, cockroaches, bed bugs and crawl space work under one license — SPCB Lic. #9119, a California-licensed business. San Leandro is really four different pest environments, and which one your street sits in decides most of the plan. We work in English and Spanish.
Home maintenance
What should a San Leandro homeowner do each season to keep pests out?
Work the house on a seasonal loop: drainage before the winter rain, sealing in spring, the yard in summer and the eaves in fall. San Leandro’s Bay flats, central post-war tracts and foothills each lean toward different pests, and this calendar covers the upkeep that helps in all of them.

Winter: keep water moving
Keep gutters, downspouts and yard drains flowing through the rainy months. After heavy storms, homes near San Leandro Creek and the Estudillo Canal should check fences, woodpiles and the garage for rat droppings and fresh burrows.
Spring: seal the stucco line
Argentine ants trail in through weep screeds, hose-bib holes and worn garage door sweeps as the rain ends. Caulk wall penetrations, replace the door sweep, and trim shrubs back so they don’t touch the walls.
Late spring: cut trees back from the roof
Old orchard trees in the central tracts link one roof to the next for roof rats. Trim branches away from the roofline and fences, and pick up fallen fruit the day it drops.
Summer: watch foothill yards for ground nests
Yellowjackets nest in the ground and in retaining-wall gaps on Bay-O-Vista and Halcyon-Foothill lots. If you see steady traffic at a hole, keep children and pets away and have it handled by a professional.
Fall: walk the eaves and gutters
Drywood termites swarm from August into October. Look for pellets under the eaves and on sills, then clear gutters before the first rain so water drains away from the house.
When to do it
Gutters in October, sealing in March and April, tree trimming in May, an eave check between August and October.

Common Questions
Residential Pest Control FAQs for San Leandro
Can one company handle termites and rodents at our San Leandro house, or do we need two?
One licensed company can do both, and in San Leandro the two usually show up together. A raised-foundation house with sub-area moisture attracts subterranean termites and hands Norway rats a way under the floor; an open eave on a 1950s tract roof lets roof rats in while giving drywood swarmers weathered wood to land on. We inspect for both on the same visit, hold SPCB Lic. #9119 for structural pest work across Alameda County, and put the findings in one written report.
What is the first thing to fix on an older San Leandro home to cut down pest problems?
Usually the places where soil, water and wood meet. On the flats and the older raised-foundation homes that means clearing debris and controlling moisture in the sub-area, and pulling planters and soil back off the siding. On the tract streets it is the eave-to-wall junction, the gable vent screens and the garage door sweep. None of that is treatment — it is the structural work that decides whether what an exterminator applies lasts more than one season.
Do you have technicians who speak Spanish in San Leandro?
Yes. Our technicians and office staff work in English and Spanish, which matters in a city as linguistically mixed as San Leandro. This work depends on explaining where we treated, what we used, and what the household needs to do before and after. That conversation has to happen in the language people actually use at home or the follow-through does not happen. Ask for Spanish when you call and we will schedule accordingly.
