In the wake of Hurricane Sandy, New Yorkers may soon be facing a plague of rats. As floodwaters filled the city's subway system, large numbers of rats were forced to the surface in search of food and shelter. Bennett Pearlman, of New York’s Positive Pest Management, explained that, while their tunnels and nests were flooded, most were able to escape via subway entrances and stairs. Thousands were seen hiding under cars and behind trash cans Tuesday as they waited for nightfall. The rats are expected to thrive above ground, where the flood has brought an abundance of sustenance in the form of rotting trash, as well as dead birds and fish.
