Rat control in the Marina District — trapping, rodent exclusion, and ongoing monitoring for waterfront homes, apartments, and the Chestnut Street restaurant corridor.
The Marina sits on filled land at sea level with the bay on one side and a tight grid of stucco apartments and homes on the other. Most buildings have a tuck-under garage at street level, and the slab-to-wall seam at the back of those garages is where we find the most consistent entry points. Once rats are in the garage, they move up the conduit and pipe penetrations into the unit above.
Chestnut Street keeps a continuous restaurant footprint from Fillmore to Divisadero. The rear alleys behind those restaurants share property lines with apartment buildings, and the trash enclosures and grease bins in those alleys feed rats year-round. We see heavy wall activity in the units backing up to those alleys.

Real patterns from rat control work in Marina District — buildings, streets, and the entry points that keep coming back.
A common Marina job: a 4-unit building on Bay or Beach Street with a tuck-under garage. The owner sees droppings on the workbench, then a tenant on the second floor hears scratching at night. The rats are entering through the gap between the garage slab and the back wall, climbing the conduit serving the kitchen stack, and nesting in the wall cavity above the stove. We trap garage and unit at the same time, then seal the slab seam and the conduit penetration.
On Chestnut, we work the rear alley side of the buildings — restaurant grease bins push activity into the residential units behind. We coordinate with the restaurant on enclosure cleanup and seal the back wall of the residential building so the food source loses its travel path inside.
On most Marina buildings the garage slab meets the back wall with a quarter-inch gap that has never been sealed. Rats slip in along that seam from the rear yard. We pack it with mortar and hardware cloth — caulk alone fails within a season.
Marina stucco moves with the soil. Cracks open at the base of the wall and rats use them as entry points. We patch with mortar, not foam — foam gets chewed through in a night.
Electrical and plumbing conduit runs continuously from the garage ceiling up into the kitchen stack. That's the rats' interior highway. We seal the penetration at the garage ceiling and again at the wall plate.
Tight alleys behind the restaurants share property lines with apartment buildings. Trash and grease bins sit against rear walls and feed rats steadily. Sealing the residential side without addressing alley sanitation just buys time.
This is not basic pest control. We trap, we seal, and we follow up — built for the way San Francisco buildings actually fail.
Full walkthrough — interior, exterior, crawl space, roofline, conduit penetrations, and trash areas.
Snap traps placed on active travel paths — along conduit, inside walls when needed, and at entry points.
Hardware cloth, mortar, and proper sealing of every gap rats are using to get in. The fix that actually lasts.
Return visits to verify activity is gone and to lock down anything new before it becomes a problem.

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 — sealing every gap they're using to get in.
Rodent exclusion is sealing the building so rats physically can't get back in. We use hardware cloth, mortar, sheet metal, and proper sealants on every entry point we identify during inspection.
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.
Tuck-under garages have the weakest sealing in the building — the slab seam, the door weatherstripping, the conduit penetrations, and the storage clutter. They're also at grade with the rear yard, so rats don't have to climb to get in.
Yes — discreet trapping, after-hours service, and exclusion work coordinated with the residential building behind. Restaurants and the apartments above usually have to be addressed together.
