Katherine Linden @ed us, asking How come there aren’t rats in SF? I hate NYC, rats everywhere.

Luis A. Agurto Jr., president of Bay Area pest management provider Pestec, told me in an email that, “In short, New York does a better job housing and feeding rats than [does] San Francisco.”

Agurto pointed out that rats, just like us, need food, water, heat, and shelter. Rats in New York have more access to these basic needs, thanks largely to New York’s “infamous waste disposal services” and the simple fact that more people = more food.

“What’s being flushed, tossed, stacked on the curb in trash bags, or not picked up after the dogs is food [for rats],” Agurto wrote. “Everything else is found in abundance in the sewers. Remember that New York is older than San Francisco, and has been built upon itself. There are sewer systems on sewer systems.” Which, of course, means rats upon rats.

For those who yearn to know more on this topic, Agurto suggested googlingt rat-expedition-going Dr. Robert Corrigan, or reading Robert Sullivan’s “excellent” book, Rats.

Note: I personally do not recommend googling “rats” unless you want to see this.
