Rat control in SoMa — trapping, full rodent exclusion, and ongoing monitoring for restaurants, apartment buildings, warehouses, and mixed-use properties throughout South of Market.
SoMa combines restaurants, apartment buildings, warehouses, loading areas, and active construction on the same blocks. Shared alleys, utility corridors, and frequent deliveries give rats steady food, shelter, and multiple ways to move between neighboring properties.
Many buildings have been converted or remodeled several times. New plumbing, electrical, and ventilation lines often leave gaps through foundations, rear walls, and shared utility spaces. Sealing those openings is what stops activity from returning after trapping.

Real patterns from rat control work in SoMa — buildings, streets, and the entry points that keep coming back.
A common SoMa restaurant call starts with droppings near dry storage after closing. The rats are often entering from a shared alley through a gap around a drain or utility line, then following the wall into the kitchen. We trap the active areas, seal the exterior opening in metal or mortar, and document the work for management.
In apartment and mixed-use buildings, we often find activity beginning in the garage, trash room, or loading area. Rats enter at the ground floor and use plumbing or electrical chases to reach units above. We coordinate access with the property manager so the building is treated as one connected system instead of chasing activity from room to room.
Gaps at the corners of roll-up doors and damaged door sweeps leave direct entry into warehouses, garages, and commercial storage. We reinforce these weak points with durable rodent-resistant materials.
SoMa properties often share narrow service alleys and waste areas. We identify the routes rats use between dumpsters and the building, then seal the openings that bring them inside.
Repeated tenant improvements leave oversized openings around conduit, plumbing, and refrigeration lines. We close those gaps with metal, mortar, and materials rats cannot chew through.
Restaurants and managed properties may need regular activity checks, trap monitoring, and clear service records. We provide scheduled visits and documentation when you need it.

"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.
