These two were found in Boston, MA…a juvenile and adult American Roach. This juvenile, including antennae is only 1″ where as the adult has a body of 1.5 inches. These roaches get BIG. These roaches can be found in sewer systems which then could lend entry in basements of buildings in city environments. These roaches behave much different than the German aka “kitchen” roach. They are not as much as a problem as the German roaches but certainly can give you a fright. These BIG American Roaches are fast and if you are quiet enough you can hear them scurrying about. Happy Halloween!
