South San Francisco runs on a single residential ZIP code, 94080, which takes in about 66,600 residents. It reaches from Old Town and the Grand Avenue shops below Sign Hill to Westborough and Avalon Park on the western hills, and east past US 101 to Oyster Point. ZIP lines do not follow city limits exactly, so a few addresses at the edges may sit just outside the city. 94083 is a post office box ZIP for the main post office.

Bed Bug Control Services in South San Francisco
Every job here begins with a careful inspection. A prewar cottage near Grand Avenue, a postwar Buri Buri house and a new apartment near the biotech campuses each hide bed bugs in different places, and the inspection tells us which method fits.

Bed bugs do not come from dirt or clutter. They travel with people, inside luggage, backpacks, work bags and used furniture, and they settle wherever someone sleeps.
The 2020 Census counted 66,105 people in South San Francisco, in roughly 21,800 households averaging about 3 people each. About 43% of homes are rented. The city calls itself the birthplace of biotechnology, since Genentech opened here in 1976, and it remains the largest employer, with more than 8,000 workers. Add BART and Caltrain stations, a weekday ferry from Oyster Point to Oakland and Alameda, and San Francisco International Airport right next door, and you get a city where people and their bags are always on the move.
Most homes in 94080 went up in the 1940s, and close to 2,900 date from before 1940. Since 2007, more than 1,000 new apartments have been added. That mix of old wood trim, plaster walls and busy new rental buildings shapes where we look and how we treat.
Next Door to SFO: Airport Hotels, Flight Crews and Conference Trips
The southern part of South San Francisco borders the airport, and that edge of the city is lined with airport hotels, long term parking lots and car shops. SFO itself sits on unincorporated San Mateo County land and has its own ZIP. For residents, the airport matters less as a neighbor and more as a daily part of life. Many households include airline crews, hotel staff, airport workers or biotech employees who fly to meetings and scientific conferences.
- Uniforms and work bags: change at the door, keep a lidded hamper there and dry work clothes on high heat before they reach the bedroom closet.
- Hotel nights: lift the sheet at the head of the bed and check the mattress corners and headboard before you unpack, and keep the suitcase on the rack.
- Coming home: open luggage on a hard floor or in the tub, never on the bed, and store it in the garage rather than under the bed.
Old Town's Early Houses and the City's New Apartment Blocks
South San Francisco was planned in 1888 around the meatpacking industry, and the oldest homes still stand in Old Town around Grand Avenue, Linden Avenue and Baden Avenue. Many are small wood houses and flats with decades of paint, gaps behind baseboards and loose door casings. Bed bugs use those cracks as hiding places, so in these homes we check the trim and the walls near the bed, not only the mattress.
The newer apartment buildings have the opposite problem. Units share walls, plumbing chases and hallways, and tenants come and go with every lease cycle. When we confirm bed bugs in one unit, we suggest asking the manager to check the units on each side and above and below.
- Older house or flat: expect us to pull outlet covers, look behind loose trim and check picture rails and door frames near the bed.
- Apartment tenant: report signs to the manager in writing and keep a dated copy. The owner normally arranges treatment.
- Used furniture: check sofas and bed frames from online listings outside on the sidewalk or driveway first.

Small reddish brown stains on sheets and pillowcases from crushed bugs.
Dried droppings that look like marker dots on seams, tags and frame joints.
Empty, see-through skins shed as the young bugs grow.

South San Francisco Renters and Bed Bug Law
Roughly 4 in 10 households in the city rent. California's AB 551, written into Civil Code 1954.600 to 1954.605, protects every one of them, whether they lease an apartment near the BART station, a flat in Old Town or a room in a house in Westborough.
- Landlords must give tenants a written bed bug notice.
- A landlord cannot show, rent or lease a unit they know has bed bugs.
- After a licensed pest control operator inspects, the landlord must share the findings with affected tenants within 2 business days.
- Tenants who report bed bugs are protected from retaliation.
Send your report by email or letter, add the date and keep a copy with any photos. If you rent a room from a homeowner, the same rules apply to the person you pay rent to.
What Bed Bug Treatment Costs in South San Francisco
The number of rooms involved drives the price more than anything else, so catching bed bugs while they are still in one bedroom keeps the bill down. For a rough idea, Angi's 2026 US averages list a visual inspection at $65 to $200, a K9 search at $300 to $600 and treatment at $200 to $400 per room, with whole home work usually landing between $1,500 and $6,200. Your written quote, based on what we find in your home, is the number to plan around.
South San Francisco Bed Bug FAQ
Which ZIP code do you serve in South San Francisco?
All of the city's homes use ZIP 94080, and we cover the whole of it: Old Town and downtown Grand Avenue, Sunshine Gardens, Buri Buri, Westborough, Winston Manor, Avalon Park, Paradise Valley, Terrabay and the rest. 94083 is a post office box ZIP with no homes, so it has no area page of its own.
I work at a biotech campus and travel to conferences a lot. What should I do when I get home?
Treat your carry-on and laptop bag as the risky items. Unzip them in the garage, the entryway or the bathtub, not on the bed, and put the clothes from the trip straight into a hot dryer for at least 30 minutes. If you notice bites or small dark spots on your sheets in the weeks after a trip, call us for an inspection.
We live near the airport hotels. Are we more likely to get bed bugs?
Living near a hotel does not bring bed bugs into your home. People do, in bags and on clothing. What matters is who stays over, where you travel and what used furniture comes in.
Can bed bugs survive in a cool, foggy house?
Yes. Bed bugs live where people sleep, and a bedroom kept at normal indoor temperatures suits them well. A cool house can slow their growth a little, but it will not stop them. This is also why we never rely on weather or an unheated room to kill them.
How much does bed bug treatment cost in South San Francisco?
It depends on how many rooms are involved, the size of the home and the method we recommend. Angi's 2026 US averages put a visual inspection at $65 to $200, a dog search at $300 to $600, a single treated room at $200 to $400 and a full home at about $1,500 to $6,200. We give you a written total after we inspect.
