Residential Pest Control in South San Francisco, CA
101 Exterminators provides residential pest control in South San Francisco for single-family houses, townhomes and condos, California licensed under SPCB Lic. #9119 and working since 2005. A 1950s ranch in Buri Buri, a pre-1940 bungalow off Linden Avenue and a townhome on the Terrabay slope do not share the same pests or the same weak points. We inspect the house you actually own, in English or Spanish.

Common Questions
Residential Pest Control FAQs for South San Francisco
What pests should a South San Francisco homeowner expect in a normal year?
Argentine ants twice a year, spiders continuously, rodents through fall and winter, and yellowjackets in late summer. The ant waves follow the rain — indoors when the first storms saturate the ground in November, indoors again once the soil dries out in late summer. Roof rats push into attics as nights cool. Termites are the slow one: subterranean and dampwood on the fog side, drywood on the warmer bay-facing slopes, usually found by inspection rather than by symptom.
Is pest treatment around our South San Francisco house safe with kids and a dog in the yard?
Ask the technician on site and you will get the material, where it went and the re-entry interval before anything is applied. Most residential work here is targeted to entry points, harborage and the exterior perimeter rather than broadcast across lawns and play areas, which limits exposure by design. Rodent bait stations are tamper-resistant and placed where a dog cannot work them open. We can go through all of it in English or Spanish.
Our townhome on the Terrabay slope backs onto open space — does that change the work?
It does. Properties against the San Bruno Mountain scrub see more yellowjacket ground nests, more rodent pressure moving in from cover, and more spider activity where outdoor lighting sits near the vegetation line. The work concentrates on the back fence line, the deck framing and any planting touching the structure. Keeping a clear gap between vegetation and the building does more on that kind of lot than anything applied to the yard.
