Roaches are insects. Adults have wings but seldom fly in the northeast. Important types are the German cockroach (small - to about 1 inch), and the American cockroach (large - can be over 2 inches). Other large roaches seen indoors are the oriental and Asian cockroaches. The large roaches are not often seen in private residences in eastern Massachusetts, but are fairly common in multiple-family dwellings and commercial structures.

There are many roaches that live outdoors and some of these occasionally wander indoors. There are effective control measures for roaches that are nontoxic to people. In our area, these control measures have reduced the number of households with roaches, and have made it possible to bring an infestation under good control.

German Cockroach

The German cockroach is brownish and up to 1 inch long. It thrives in unclean areas and, in large numbers, produces a distinctive roach smell. Although German roaches have wings, they do not fly. German roaches are also known as "Croton bugs".

American Cockroach

The American cockroach can be over 2 inches long. It is also known as the "palmetto bug" and "water bug". These roaches are not as common in houses as German cockroaches, but are rather common in areas where trash collects and in some industrial settings. American cockroaches are common in the southern United States, but less seen in the north. These roaches have wings and do fly occasionally.
