A can of bug spray only hits the few bugs you can see. Most of the colony stays out of reach in mattress seams, bed frame joints and the gap under the baseboard, and a lot of bed bugs today survive the ingredients sold in stores. Home spraying can also drive them through a shared wall while eggs keep hatching.

Bed bugs ride along with people. They hide in overnight bags, instrument cases and used furniture, and a clean home is no defense.
Cotati is a small city of about 7,600 residents (2020 Census) on less than 2 square miles, and it calls itself the Hub of Sonoma County. Highway 101 runs straight through town, the SMART train stops on East Cotati Avenue, and Sonoma State University sits about a mile east of the city limits. Census figures for ZIP 94931 show about 4 in 10 occupied homes are rented, and most of the housing was built in the 1960s and 1970s.
Festival Weekends and a Late-Night Downtown
Cotati's downtown is laid out around a six-sided plaza, La Plaza Park, designed in the 1890s and now California Historical Landmark 879. Every August the Cotati Accordion Festival fills the park, with the 2026 edition held August 15 and 16. The rest of the year, bars and cafes along Old Redwood Highway, such as Tradewinds with its karaoke and trivia nights and the Redwood Cafe with evening live music, draw people in from around the county.
Busy weekends often end with friends crashing at a local home, when a guest bed, futon or couch can pick up hitchhikers. These habits help:
- Give overnight guests a hard floor or a luggage rack for bags instead of a bed or sofa.
- After visitors leave, strip the guest bed and dry the sheets and blankets on high heat for at least 30 minutes.
- If anyone reports bites the week after, leave the bedding in place and call for an inspection rather than moving guests to another room.
Duplexes, Small Apartment Buildings and Mobile Homes
Much of Cotati's rental housing is small scale: duplexes, fourplexes, older apartment buildings from the 1960s and 1970s, and around 100 townhomes built in the early 2000s along Santero Way near the train station. The city also has mobile home parks, which fall under their own city space rent ordinance.
- In a duplex or fourplex, bugs can cross between units through wall gaps and plumbing runs, so ask for the attached units to be checked too.
- Mobile homes have built-in furniture and lighter construction, so mention the home type when you call, since some heat and fumigation setups must be adapted.

Renting in Cotati? California Law Is on Your Side
California Civil Code 1954.600 to 1954.605, known as AB 551, covers bed bugs in rental housing statewide, including Cotati duplexes, apartments, townhomes and rented houses.
- 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.
With roughly 4 in 10 homes in 94931 rented, a lot of Cotati households are covered by these rules. Report bed bugs to your landlord or property manager in writing, date the note and keep a copy for yourself.
What Bed Bug Treatment Costs

Cotati Bed Bug Questions
Does ZIP 94931 cover all of Cotati?
Yes. Cotati uses a single ZIP code, 94931, on both sides of Highway 101, from the downtown plaza and Old Redwood Highway out to the SMART station on East Cotati Avenue.
Friends stayed over for the Accordion Festival and now I have bites. Could they have brought bed bugs?
It is possible. Any overnight guest, bag or sleeping bag can carry a few bugs in. Leave the guest bed and couch as they are, wash the bedding on high heat and book an inspection before anyone sleeps there again.
I live in a duplex. Should my neighbor be inspected too?
Ideally, yes. Bed bugs can travel through shared walls, plumbing gaps and a shared laundry area, so ask your landlord or the owner to have both sides checked at the same visit.
How much does bed bug control cost in Cotati?
Three things set the price in Cotati: home size, how many rooms have bugs and the treatment chosen. Angi's US averages put treatment at about $200 to $400 per room, and a full house often lands between $1,500 and $6,200. Rely on the written quote you get after the inspection.
Will a fogger from the hardware store take care of it?
Unlikely. Ohio State researchers tested 3 retail foggers and found almost no effect on bed bugs, and the spray can drive the survivors into walls or the unit next door.
