Rat Control in
Pacific Heights, San Francisco
Rat control in Pacific Heights — trapping, full rodent exclusion, and follow-up monitoring for the Victorians, Edwardians, and multi-unit buildings between Divisadero and Van Ness.
Why rats are a problem in Pacific Heights.
Pacific Heights is mostly Victorians, Edwardians, and 2–6 unit buildings sitting wall-to-wall on long blocks between Sacramento and Broadway. Foundations have settled, vents have rusted out, and the gas and electrical penetrations on the side of the building were never sealed when service was upgraded — those are the entry points we find on almost every Pac Heights call.
Rear gardens and shared trash areas behind the buildings give rats food and cover all year. We see the heaviest activity in the wall cavities behind kitchens on the parlor floor and in basement laundry rooms backing up to neighboring properties.
Common signs in Pacific Heights buildings
- Scratching in walls behind the kitchen after 10 p.m.
- Droppings in the basement near gas/electrical penetrations
- Grease marks along baseboards in pantries
- Activity in the garden along fence lines at dusk
What we run into on Pacific Heights jobs.
Real patterns from rat control work in Pacific Heights — buildings, streets, and the entry points that keep coming back.
On a typical Pac Heights job we find rats traveling the gas line up the side of the building, into the wall cavity behind the stove, and out into the upper units through the same chase. The owners on the top floor hear it first because the rats are running joist bays directly above their ceiling.
The other recurring pattern: a 4-unit Edwardian on Clay or Washington with a shared trash enclosure in the rear yard. Rats nest behind the bins, run the foundation seam to the side of the building, and enter through a rusted dryer vent or weep hole. Sealing the vent without addressing the trash enclosure just pushes them to the next gap.
Gas line penetrations on the side of the building
When PG&E upgrades service, the new line goes through the original opening with foam — not metal. Rats chew foam in a single night. We seal these with hardware cloth and mortar so the next service upgrade doesn't reopen the gap.
Wall activity above parlor-floor kitchens
If you hear running above the cabinets between 10 p.m. and 1 a.m., the rats are in the cavity between the kitchen ceiling and the floor above. We trap from below, then exclude the chase the rats are using to reach that cavity.
Shared rear-yard trash enclosures
Most Pac Heights blocks share trash space between buildings. Bin lids don't seat after collection day, and the rats nest in the gap between the enclosure and the back wall. We address harborage there before sealing the building, otherwise the population just relocates.
Crawl-space access doors that never sealed
Crawl-space hatches on the side or back of Edwardians warp over time and stop closing tight against the frame. We replace the gasket and add hardware cloth on the inside so rats can't pry through the gap.
Our rat control process in Pacific Heights.
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.

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.
Do most Pacific Heights buildings need exterior exclusion?
+
Yes. The age of the housing stock and the way utilities have been re-run over the decades means there are almost always unsealed penetrations on the side of the building, in the rear, and around the foundation. Trapping alone won't hold here.
Can you work in occupied multi-unit buildings without disturbing tenants?
+
Yes. We coordinate with the owner or property manager, schedule interior work around tenant availability, and keep traps in covered, tamper-resistant placements. Common areas, basement, and exterior work happen with no disruption.
