Trapping, full building exclusion, and follow-up monitoring for restaurants, apartment buildings, and mixed-use properties. Call or text and I'll get out there.
My approach to rodent control in San Francisco starts with a full inspection. I trap the active rats, then seal the building so the next ones can't replace them — no drop-a-bait-station-and-leave service.
I walk the property top to bottom — roofline, vents, conduit, crawl space, trash area — and map the actual entry points and travel paths before quoting.
Snap traps placed on the runways the rats are already using, monitored until the building goes quiet. No poison left in your walls.
For rodent exclusion in San Francisco buildings, I use hardware cloth, mortar, sheet metal, and copper mesh to close the entry points identified during inspection.
Scheduled service visits, trap monitoring, activity checks, and service documentation for commercial properties and apartment buildings.

Most buildings in SF are old. Victorians, Edwardians, apartments built on top of shops. The walls are solid, but there are gaps everywhere — around gas lines, pipes, wiring, and along the foundation. Once rats get into one building, they move right through the walls into the next one.
Then there's the food. Restaurants, cafés, and corner stores sit right behind apartment buildings in tight alleys. Trash bins don't close all the way, lids get left open, and grease builds up around the back doors and vents. That's why most of the activity ends up in the walls near kitchens, grease traps, and storage rooms by the trash.
And it mostly happens at night. The scratching in the walls usually starts after 10 p.m., once the building goes quiet. By morning, you'll see droppings or dark smudges along the baseboards — that's how I figure out where they're traveling.
Different buildings, same problems. If any of this sounds familiar, give me a call.
Anywhere a pipe or wire enters your building, there's usually a gap around it. Rats climb those lines from the basement up to the roof and slip in through the openings. It's the first thing I look for, and it's where I find them most of the time.
If you hear scratching at night near the stove or above the cabinets, they're living in the wall. Kitchens give them everything — food, warmth, and quiet places to nest.
If lids don't close or bins overflow, the rats have a free meal every night. I can seal your building, but if the trash next door isn't handled, they'll keep coming back.
Some companies plug a few holes and call it done. If rats are still inside, they die in the walls and the smell can last for weeks. I trap first, make sure the building is clear, then seal it up.
A lot of SF buildings sit only a foot or two apart. Rats use that narrow space as a hidden path to reach vents and openings on the side of your building you never see. I always check both sides, not just the front.
Quiet rooms with boxes, dry goods, or laundry are some of their favorite spots. Droppings usually pile up along one wall — that tells me exactly where they're traveling before I set a single trap.
Rats are skilled at staying out of sight. We know exactly where to look — even in the most overlooked corners of San Francisco buildings.

Call or text with what you're seeing, and I'll give you the earliest available time. Urgent commercial issues are prioritized when scheduling allows.
I'm a licensed trapper, not someone who shows up to refill a box. I trap the rats, then I seal the building so the next ones can't get in.
Discreet visits, after-hours scheduling, and written reports for owners or health inspectors when you need them.
I give you a price after I've actually walked the property. No mystery numbers, no upsells you don't need.
I've worked with restaurants, apartment buildings, and commercial properties all over San Francisco. The goal is always the same: get rid of the rats that are there now and seal the building so new ones can't get in.
Discreet service that meets health-code expectations.

"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."

Around pipe and conduit penetrations, foundation cracks, roofline gaps, vents, and unsealed crawl-space hatches. They only need a hole the size of a quarter, and SF buildings are full of them — especially anything pre-1940.
Fast. One pair can run 5–8 litters a year, 6–12 pups each. A couple of rats in the wall in October is a serious infestation by spring if the entry points stay open.
No — and anyone who says yes is going to be back at your building in a month. Trapping clears what's inside; exclusion seals the building so new rats can't replace them. You need both.
Sealing the entry points identified during inspection with the right materials — hardware cloth, mortar, sheet metal, copper mesh on weep holes, and proper sealant on conduit penetrations. Not foam or caulk over a hole; rats can chew through those materials.
Yes. A lot of my work is restaurants, apartment buildings, HOAs, and property managers. I do after-hours and weekend visits, keep it discreet, and provide documentation for health inspectors or owners when you need it.
Depends on the property and how active it is. I quote after I've actually walked the building — no over-the-phone guess. Inspections are straightforward and there's no pressure.
Call or text. Tell me what you're hearing or seeing and where. I'll inspect the building and recommend a clear plan for trapping, exclusion, and follow-up.
