Rodent Control in San Francisco County, California

Rodent Pressure in San Francisco County

San Francisco is a dense urban county occupying a 47-square-mile peninsula with over 870,000 residents and an enormous daily commuter population. The city's Victorian and Edwardian housing stock, much of it built between 1860 and 1920, features balloon-frame construction, interconnected wall voids, and aging foundations that provide extensive rodent harborage. Norway rats dominate the city's pest landscape, thriving in the extensive sewer system, BART tunnels, waterfront areas, and underground utility corridors. Roof rats are increasingly problematic in neighborhoods with mature street trees and dense vegetation like Pacific Heights, the Sunset, and the Richmond. Commercial districts including the Financial District, Chinatown, and the Mission experience persistent rodent pressure from high-volume food service operations, aging commercial infrastructure, and dense foot traffic that generates food waste.

Dense tree canopy throughout Oakland, Berkeley, and the peninsula creates extensive roof rat habitat. Bay shoreline proximity supports large Norway rat populations near marinas, storm drains, and waterfront restaurants. Older housing stock across the East Bay flatlands features raised foundations, balloon-frame construction, and aging stucco — all of which create persistent entry opportunities. Urban composting programs and backyard chicken coops add food attractants in residential neighborhoods.
