Rat Control in
Russian Hill, San Francisco
Rat control in Russian Hill — trapping, rodent exclusion, and ongoing monitoring for hillside Victorians, garden apartments, and the restaurants along Polk and Hyde.
Why rats are a problem in Russian Hill.
Russian Hill is hillside construction stacked tight — Victorians, garden apartments, and pre-war buildings sitting on retaining walls and crawl-space foundations. The grade gives rats easy access from one property's roof to the next property's basement, and the retaining walls on the back side of buildings are full of weep holes that were never screened.
Polk and Hyde keep a steady restaurant footprint on the east side of the neighborhood. Mature ivy and jasmine on the upper blocks gives roof rats cover into the rooflines and attic vents. We see attic and roof activity here more than almost anywhere else in SF.
Common signs in Russian Hill buildings
- Scratching in rooflines and attic spaces at night
- Droppings in garages and lower-level storage
- Chewed wires or insulation in the attic
- Rats sighted on fence lines and ivy at dusk
What we run into on Russian Hill jobs.
Real patterns from rat control work in Russian Hill — buildings, streets, and the entry points that keep coming back.
On a typical Russian Hill job, the call comes from the top floor — scratching above the bedroom ceiling. The rats are roof rats traveling ivy or a tree branch onto the roof, dropping in through an unscreened attic vent, and nesting in the insulation. We trap the attic, screen every vent in metal mesh, and cut back the access vegetation so they can't reach the roof again.
On the lower side of the hill we run into garden-level units with crawl space underneath. Rats enter through a foundation weep hole on the downhill side, set up in the crawl, and come into the unit through the bathroom plumbing penetration. Sealing the weep hole and the plumbing chase together is the only way to keep them out.
Attic entries from rooflines and trees
Russian Hill has more roof-rat pressure than Norway-rat pressure on the upper blocks. Vent screens rust through, and overhanging branches give rats a clean path onto the roof. We screen vents in galvanized hardware cloth and trim back contact points.
Retaining-wall weep holes
The retaining walls on the back side of hillside buildings have weep holes for drainage. Almost none of them are screened. Rats use them as a back door into the crawl. We screen them with metal mesh that still allows drainage.
Garages built into the hillside
Sub-grade garages have the worst sealing in the building — the door tracks, the conduit penetrations, and the gap where the slab meets the wall. We trap inside the garage and seal every gap before moving upstairs.
Restaurant alleys behind Polk and Hyde
Tight rear access, shared trash, and grease deposits on the back walls. We coordinate with both the restaurant and the residential building above so trapping happens on both sides at the same time.
Our rat control process in Russian Hill.
This is not basic pest control. We trap, we seal, and we follow up — built for the way San Francisco buildings actually fail.
1. Inspection
Full walkthrough — interior, exterior, crawl space, roofline, conduit penetrations, and trash areas.
2. Strategic trapping
Snap traps placed on active travel paths — along conduit, inside walls when needed, and at entry points.
3. Rodent exclusion
Hardware cloth, mortar, and proper sealing of every gap rats are using to get in. The fix that actually lasts.
4. Monitoring & follow-up
Return visits to verify activity is gone and to lock down anything new before it becomes a problem.

What San Francisco clients say.
"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."
Rat control questions, answered.
How do rats get into walls?
+
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.
How quickly can a rat infestation grow?
+
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.
Do traps alone solve the problem?
+
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.
What is rodent exclusion?
+
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.
Do you service restaurants and apartment buildings?
+
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.
How do rats get into the attic in a hillside Russian Hill home?
+
Almost always from the roofline — over a fence, up a tree branch, along a power line, or onto an adjacent rooftop. Once on the roof they use unscreened attic vents, gable vents, or the gap behind fascia boards to get inside.
Do you cut back vegetation as part of the work?
+
We identify the contact points — branches touching the roof, ivy climbing the wall — and recommend exactly what to trim. We don't do landscaping, but we'll show you what has to come back so the exclusion holds.
