Oakland's rodent problem is well documented enough that the county's vector control agency was created to deal with it. Alameda County Vector Control Services District was established in 1984 and began as the Oakland Rat Project. In 1987 the City of Oakland recognized a severe rat problem coming out of the sanitary sewers, and the district started a sewer baiting program covering roughly 8,000 manholes under contract with the city. That program has run for close to forty years, which tells you something structural about where Oakland's Norway rats come from.
The species split here follows elevation. Norway rats (Rattus norvegicus) dominate the flatlands, from West Oakland and the Lower Bottoms through Fruitvale, Chinatown and the Jack London corridor. They are ground-dwelling burrowers and strong swimmers that move through sewer lines, enter through cracked sewer laterals, floor drains, crawl space vents and foundation gaps, and burrow against footings. Roof rats (Rattus rattus) are established across the Oakland Hills, Montclair, Rockridge and the semi-urban east side, entering high along rooflines from the mature tree canopy and hillside vegetation. House mice (Mus musculus) show up across every ZIP from 94601 to 94621.
Housing stock does most of the rest. Pre-1940 Victorian, Craftsman and bungalow construction across West Oakland, Fruitvale and Temescal sits on raised foundations with vented crawl spaces, shallow footings, open utility chases and, in many cases, an original clay sewer lateral that has never been pressure tested. Oakland's Private Sewer Lateral ordinance requires an EBMUD compliance certificate at title transfer, on remodels over $100,000 and on water meter changes, which means plenty of laterals in the older neighborhoods remain uncertified. A defective lateral is a direct route from the sewer main into a building, and it is the entry point most often missed on Oakland Norway rat jobs.

Many older laterals in the flatlands have never been tested, and a cracked lateral is a direct route from the sewer main into a building.
- •Pre-1940 Victorian and Craftsman stock in West Oakland, Fruitvale and Temescal sits on raised foundations with vented crawl spaces and open utility chases, which is the construction Norway rats exploit.
- •Roof rat pressure concentrates in the hills and canyon neighborhoods, Montclair, upper Rockridge and the Oakland Hills, where mature tree canopy and dense hillside vegetation reach the roofline.
