First of all we can’t think of anything nice to say about household pests. This is especially true of the common, ordinary German Cock Roach. Yes, there are ‘insect’ researchers who spent their entire professional careers trying to seek effective control methods to help in our battle with these nasty little germ-carrying insects.

According to the Maryland Cooperative Extension office we can find four varieties of cockroaches in Mid-Maryland. They are:

  • German Cockroach
  • Brown-banded Cockroach
  • American Cockroach
  • Oriental Cockroach

Does it really matter that we have four varieties of cockroaches in our area? Short answer: yes, it does matter. The primary differences are:

German Cockroach, light brown

  • About ½” long
  • Has two dark “racing stripes “ on its back
  • Are found where there is warmth and water, hence the kitchen and the bathrooms of the house
  • The most common roach and is found in homes and apartments

Brown banded Cockroach, brown in color

  • Does not have “racing stripes”
  • Are found in warm areas
  • Eggs are glued to the ceiling, in TV sets, in dresser drawers, furniture.
  • Adult males can fly, but not the females
