(Length: 1/2″- 5/8″) The brown-banded cockroach is easily recognized by alternating light and dark bands across its back. About the same size as the German roach, but not as dependent on moisture, it can be found anywhere in the structure. The Brown Banded roach doesn’t multiply as fast as the German, but is considered harder to control because they tend to be scattered all over the structure. It shows a preference for warmer areas over 80 degrees. They are often found high on walls, in picture frames, behind molding, near appliance motors, in light switches, closets and furniture.
