The American cockroaches are the biggest type of roach you will find around Washington. The yellow band behind their heads is what you can use to tell them apart from other types of cockroaches. They also have wings, can fly(not very good), and are good at climbing walls.

They can grow up to about 2 inches in size and are reddish brown in color. They are not called American cockroaches because they are native to America; they are believed to have migrated from Africa in the ships when ships were the major means of transportation which is why they are also called ship cockroaches.

When they are outdoors, you will see them in the cracks of sidewalks and under leaf debris. But when they come inside the house, they stay in places like their basement and other dark places feeding on whatever garbage they can find. 


  • German Cockroach

German cockroaches are considered to be pests and the worst type of cockroach to find in your house. One of the reasons is that they are small (around 1.6cm), so it is easy for them to enter anywhere no matter how small the space or crack looks.

It is quite common for people to unknowingly carry German cockroaches inside their houses from elsewhere because of how small they are and how easily they can fit into cartons and clothing.

Another reason is that they breed very quickly and will produce over a thousand offspring in a short period. German cockroaches have wings but rarely fly. They prefer to run. Their distinguishing feature is the two black stripes behind their heads.

They are the cockroaches you will find in your kitchen and bathrooms, but also in places like under cabinets and behind appliances where they will feed on crumbs of leftover food and other things they find.
