I attempted in 1939 to gather data on the life history of this cockroach. I was carrying on similar work on the wood-roach, Parcoblatta pennsylvanica Deg. and the American cockroach, Periplaneta americana L. However, B. germanica were so quick in their movements and escaped so easily, that I found it necessary, since my laboratory is in my home, to abandon the project. Some data were gathered, however, before the project was abandoned, on the period of incubation and the length of life of the immature roaches.
