General Pest Management
General Pest Control in South San Francisco, CA
101 Exterminators runs scheduled general pest control in South San Francisco for homes and small businesses, California licensed under SPCB Lic. #9119 and working since 2005. Winter lows here average 44 to 46°F. That is cold enough to slow Argentine ants, cockroaches and spiders down, and never cold enough to reset them. It is the reason a service interval outperforms a one-time spray in this city.
Warning Signs
Signs You Need Pest Control Service in South San Francisco
We offer scheduled maintenance programs on monthly, bi-monthly (every 8 weeks), and quarterly (every 12 weeks) cycles. Each visit includes a perimeter treatment, interior inspection, spot treatments for active areas, and documentation. Every program includes free re-treatment between scheduled visits if pests return — we don't charge extra to finish the job.
Ant trails along baseboards, countertops, or exterior walls — especially in spring and fall
Cockroach droppings (small, dark, pepper-like specks) in kitchen cabinets or drawers
Spider webs accumulating faster than you can remove them — especially black widows in garages
Silverfish damage to paper, cardboard, or fabric — irregular holes and yellow staining
Earwigs or centipedes regularly entering through doors, windows, or crawl space vents
Pantry moths (Indian meal moths) in dried goods — visible webbing and larvae in food
Seeing one cockroach — they are almost never alone
How It Works
Our Pest Control Process in South San Francisco
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in South San Francisco.
Initial Inspection & Assessment
We walk the property thoroughly — exterior perimeter, garage, crawl space access points, interior corners, and utility penetrations — to understand pest pressure and entry points.
First Treatment
A comprehensive initial treatment targets active pests and establishes a chemical barrier. We treat entry points, nesting areas, and conducive conditions with EPA-registered products.
Scheduled Maintenance Visits
Return visits maintain the barrier and address any seasonal pest pressure changes. We keep records of each visit so you can see the history of protection on your property.
Free Re-Treatments
If pests breach the barrier between visits, call us. We return at no charge as part of your plan — because our goal is actual pest-free results, not just completed appointments.
Why 101 Exterminators
Pest Control You Can Count On in South San Francisco
IPM-Based Approach
Integrated Pest Management means we inspect first, identify species, seal entry points, and treat with the minimum necessary product — not a blanket spray of everything.
Documented Service History
Every visit is documented. You receive a service record showing what was treated, what products were used, and what we found — important for rental properties, health inspections, and peace of mind.
Free Re-Treatment Guarantee
Between scheduled visits, if you see activity we treated for, call us. We come back at no additional charge. This is our commitment, not a fine-print exclusion.
Child & Pet Aware Products
We use EPA-registered products applied in targeted areas, not broadcast indoors. We discuss any pet or child safety considerations with you before every treatment.
Common Questions
General Pest Control FAQs for South San Francisco
How often should a South San Francisco home be on a pest service schedule?
Bi-monthly or quarterly covers most houses here; monthly is for restaurants along Grand Avenue, multi-unit buildings, and properties backing the open space on San Bruno Mountain. The interval matters because winter never stops anything in this city — lows of 44 to 46°F slow ants and roaches without ending the cycle. We set the schedule after the first inspection rather than putting every address on the same plan.
Ants show up in my Sunshine Gardens kitchen every November — is that the rain?
Almost certainly. Nearly all of South San Francisco's rain falls between November and March, and the first storms saturate shallow soil along Colma Creek and Baden Creek, pushing Argentine ant nests up and toward dry structures. Sunshine Gardens sits close enough to that drainage to feel it early. Treating the exterior before the storms arrive holds the pressure at the foundation line instead of at your counter.
Do your technicians speak Spanish in South San Francisco?
Yes — our technicians and our office both work in English and Spanish. Around one in five residents citywide speaks Spanish at home, and in the downtown neighborhoods off Grand Avenue that share is far higher. On scheduled service it matters more than people expect: you need to describe what you have been seeing and where, and we need to explain what was applied, where it went, and what to do afterward.
