Cockroaches
There are about 30 species of cockroaches that are associated with human habitats. The most common species we have in the Coachella Valley are: The American Cockroach, Oriental Cockroach, German Cockroach, and Brown-banded Cockroach. These pests prefer warm conditions found in and around buildings. Cockroaches leave behind chemical trails in their feces, as well as airborne pheromones for swarming and mating. These chemical trails can transmit bacteria onto surfaces. Cockroaches also can pick up disease causing bacteria like salmonella on their legs and later transfer them on foods and cause food poisoning.
