A line of bites across your shoulder after a night in your own bed, black pepper specks on a fitted sheet, or a flat brown bug walking up the headboard: that is usually how a San Mateo bed bug case starts. Our licensed technicians inspect and treat 1940s bungalows near Central Park, apartments by the downtown Caltrain station, family homes in Baywood and Laurelwood, and the new mid-rise flats at Bay Meadows.

A bug bomb coats the tops of tables and floors, yet bed bugs rest inside mattress tufts, headboard bolts and the crack behind the baseboard, so the mist barely touches them and often pushes them into the next room.

Bed bugs are hitchhikers, not a sign of a dirty home. They ride in carry-on bags, moving boxes and used furniture.
The 2020 Census counted 105,661 people in San Mateo, the most populous city in the county, living in 40,263 households. Just over half of those homes, about 50.2%, are rented. Three Caltrain stations (San Mateo, Hayward Park and Hillsdale), US 101, Interstate 280 and State Route 92 keep commuters moving through. The county medical center is the largest employer, followed by Sony Interactive Entertainment, and many office workers travel for business.
Old Walk-Ups, Bungalows and New Mid-Rises by the Tracks
San Mateo grew up around the railroad. Its first town plat was drawn in 1862 while the San Francisco and San Jose Railroad was being built, and the city incorporated in 1894. In 94401, 94402 and 94403 the most common decade of construction is the 1940s, so a lot of homes are wood-frame bungalows, duplexes and small walk-up apartment buildings with original trim and plaster walls.
The newest housing looks very different. The 83-acre Bay Meadows racetrack, which ran from 1934 to 2008, was rebuilt as a transit village with apartments, offices, parks and a new Hillsdale Caltrain station. A 55-foot height limit in place since 1990 keeps most new complexes to mid-rises with long shared corridors.
In older homes we spend extra time on picture rail and door casings. In mid-rises we ask management about the units on each side of yours.
Moving Into a San Mateo Rental: A Quick Check
San Mateo rents are among the highest in the country; a 2018 ranking placed its median rent ninth nationwide. High rents mean many people share a house, sublet a room or move every year or 2, and each move is a chance for bugs to come along.
- Before you sign, ask the landlord for the written bed bug notice that AB 551 requires.
- On move-in day, look at mattress seams, the bed frame and outlet covers with a flashlight before unpacking.
- Run your clothes and linens through a hot dryer for 30 minutes as you unpack.

San Mateo Renters and Bed Bug Law
California Civil Code 1954.600 to 1954.605, known as AB 551, sets the bed bug rules for every rental in the state. In San Mateo that covers downtown studios, Baywood duplexes, rented rooms in Hillsdale houses and new units at Bay Meadows.
- 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.
Report signs to your landlord in writing the same day, and keep a copy. For questions about city housing programs, the City of San Mateo housing staff can tell you what applies to your unit.

San Mateo Bed Bug FAQ
Which San Mateo ZIP codes do you work in?
All 4 of them: 94401 (Downtown, Central Park, North Central and the bayside blocks toward Coyote Point), 94402 (Baywood, Aragon, the College of San Mateo hills and the unincorporated Highlands), 94403 (Hillsdale, Bay Meadows, Beresford and Laurelwood) and the San Mateo part of 94404 east of US 101.
My mailing address is 94404. Is that San Mateo or Foster City?
Most homes in 94404 are in Foster City, which has been its own incorporated city since 1971 and does not have a separate page on our site yet. A smaller slice of 94404 east of US 101 is inside San Mateo city limits. We can inspect and treat on either side of that line, and AB 551 applies to rentals in both.
I rent a room in a San Mateo house. Who pays for bed bug treatment?
In most rentals the owner arranges and pays for treatment once a licensed pest control operator confirms bed bugs. Tell the owner in writing, by text or email with a date. If you sublet from another tenant, both of you should notify the owner, since AB 551 duties sit with the landlord.
Do the new apartments at Bay Meadows get bed bugs too?
They can. Bed bugs travel on people and belongings, not through dirt, so a building opened last year is just as exposed as a 1940s duplex. In newer mid-rise buildings the management office usually runs the response, so report signs to them and ask that units next to yours be checked.
How much does bed bug treatment cost in San Mateo?
It depends on the square footage, how many rooms have activity and the method. As a guide, Angi 2026 US averages show $65 to $200 for a visual inspection, $300 to $600 for a K9 search and $200 to $400 for each treated room. We write down your actual price after we inspect.
