American Cockroach

(Periplaneta americana)

The American cockroach is the largest of the common cockroach pests found in Britain. Not as common as the German or Oriental, they are omnivorous eating anything from decomposing food to other roaches.


American cockroaches are reddish to dark brown, with red and tan on their head. Adults are 20 - 40mm long, with wings longer than the abdomen in males, and shorter with females. The nymphs are exact replicas of their parents.


It will take an American cockroach over 1 year to reach from egg to adult. A female will lay around 50 oothecae (Egg Case) in her lifetime, with around 10-16 eggs per ootheca. Nymphs will go through 10-13 moults before they become adults.


They are considered omnivorous but prefer to feed on starchy or decaying foods but will eat almost anything they can. They can get most of their water consumption from their surroundings and food they eat but can live without food for around 30 days, but without water only around 15 days.

These cockroaches are often found in sewers, heating ducts greenhouses and large central heating areas, such hotel or hospital boiler rooms.
