About Oriental Cockroach
The oriental cockroach (Blatta orientalis) is a large, glossy dark-brown to black roach measuring 20–27 mm, commonly called the 'water bug' or 'black beetle.' It favors cooler, wetter conditions than other roach species, living in sewers, drains, basements, and leaf litter around building exteriors. It moves more slowly than other cockroaches, making it easier to spot, but populations in drains and crawl spaces are difficult to reach with treatments. Its strong musty odor is a reliable sign of infestation, and it carries E. coli, Salmonella, and other pathogens on its body and legs.
Geographic Distribution
This insect is found across South America, with notable populations in Argentina and surrounding regions.
