Rat control in Hayes Valley — trapping, rodent exclusion, and ongoing monitoring for the Victorians, condo buildings, and restaurants along Hayes Street.
Hayes Valley mixes original Victorians with newer condo buildings on tight blocks between Gough and Divisadero. The Hayes Street restaurant corridor — from Octavia to Laguna especially — keeps food pressure on the residential blocks behind it day and night. Once rats are working the alley side of a building, they push into the units through the rear walls.
Older foundations have settled, vents have rusted, and shared trash enclosures sit against the back walls of mixed-use buildings. We see consistent wall activity in units that back up to Hayes Street and the cross-streets just off it.

Real patterns from rat control work in Hayes Valley — buildings, streets, and the entry points that keep coming back.
A typical Hayes Valley job: a renovated Victorian on Linden or Ivy with a unit at the rear of the ground floor. The tenant hears running in the wall behind the kitchen every night. The rats are coming from the alley behind the building, climbing the gas line into the wall cavity behind the stove, and traveling the chase up to the unit above. We trap the cavity, seal the gas penetration, and harden the alley-side vents.
On the newer condo buildings, the pattern is utility chases. Rats enter through an unsealed conduit penetration in the parking garage or trash room and use the chase to reach upper floors. We coordinate with the HOA or property manager to seal the chase at the source and trap the affected units.
Hayes Valley back walls face tight alleys where rats run undisturbed at night. Gas penetrations and dryer vents on those walls are the most common entry points. We seal in metal — foam and caulk fail within a season.
Units backing onto Hayes Street pick up steady activity in the kitchen walls because of the food density on the corridor. We trap the cavity from inside the unit and seal the rear wall penetration the rats are using to get in.
Condo trash rooms with bin storage and chute access are reliable harborage if not maintained. We trap the room, identify the conduit penetrations rats are using to leave the room, and seal those at the wall.
When a Victorian has been converted to retail or restaurant on the ground floor with units above, activity moves between them through utility chases. We treat the building as one job, not two.
This is not basic pest control. We trap, we seal, and we follow up — built around the unique challenges of San Francisco buildings.

Rat control and rodent exclusion across the surrounding San Francisco neighborhoods.
"John did an excellent job resolving a mouse issue in a commercial kitchen. He arrived promptly, diagnosed the problem immediately, and had it resolved within two days using a few strategic traps. He is clearly very knowledgeable and experienced. Highly recommend his professional services!"
"John is a hardworking, incredibly diligent rodent control expert. He came to the site multiple times in the cold, rainy, dark and thoughtfully put together a plan to mitigate the problem. Thank you."
"John is very easy to work with and clearly passionate about what he does. He took the time to understand the root cause of our rat problem and focused on solving it properly, not just putting a temporary fix in place. Professional, knowledgeable, and thorough. I would absolutely recommend John to anyone dealing with rats and wanting the problem handled the right way."
Through gaps around pipes, conduit, foundation cracks, vents, rooflines, and unsealed crawl-space access. Rats only need a hole the size of a quarter to squeeze through, and SF buildings are full of them.
Fast. A single pair can produce 5–8 litters a year, with 6–12 pups per litter. A handful of rats becomes a serious problem in a matter of months if entry points aren't sealed.
No. Trapping removes the rats currently inside, but if the entry points stay open new rats move in. Real rodent control combines trapping with exclusion work focused on the entry points identified during inspection.
Rodent exclusion is closing identified entry points with durable materials. We use hardware cloth, mortar, sheet metal, and proper sealants based on what the inspection finds.
Yes. We work with restaurants, apartment buildings, HOAs, and property managers throughout San Francisco — discreet service, after-hours availability, and documentation when you need it.
Yes. Restaurant work on Hayes is almost always coordinated with the residential building above or behind. Treating only the restaurant pushes the activity into the residential units, and vice versa.
Typical 2–4 unit Victorians take two to four visits — initial inspection and trap set, follow-up trapping, then exclusion work once the building is verified clear. We don't rush the seal: closing entry points with rats still inside causes more problems than it solves.
