Bed Bugs in San Francisco
Last reviewed:
San Francisco is dense. Victorians cut into flats, apartment buildings with long shared walls and small units mean that a problem in one household can easily reach the next. This guide is built around that density.
Your first week
- Identify the bug. A sealed bag with a specimen, plus photos of droppings along mattress seams, gives a professional something to confirm.
- Report it to whoever manages your building, in writing, and keep a copy. In a small building the owner may be close by; in a larger one, go through the management office.
- Contain your own belongings. Wash and dry bedding on high heat, and keep clean items in sealed bags away from the infested room.
- Tell the units next to yours if you have good relations with them, or ask the landlord to. Early notice limits the spread.
Flats, Victorians and dense buildings
In an older building divided into flats, households share stairwells, walls and sometimes a basement or garage. Bugs commonly travel through shared walls and utility chases, so treatment is most effective when the units around yours are inspected at the same time. Larger buildings usually have a manager who can authorize a coordinated treatment.
Small units also make preparation harder. Plan where belongings will go during treatment, and ask your exterminator for a written prep list.
Mild weather and year-round activity
San Francisco's mild weather means there is no off-season for bed bugs, and cool weather will not kill them. Professional heat treatment works year-round, and a good exterminator can tell you how long you need to be away.
What to ask a local exterminator
- Are you licensed to do structural pest control in California?
- How will you coordinate with neighboring flats, and who is responsible for the cost?
- What is the written guarantee, and what do I need to do to keep it valid?
- What preparation do you need from me, and can I get it in writing?
Official resources
For help with a rental, start with your city or county's housing or code enforcement office, and check your state's pest control licensing agency to confirm an exterminator's license. A local legal aid group can tell you what your lease and local rules say about pest problems. This site is not legal advice.
