Reported in Texas, Louisiana and Florida. Native to humid tropics worldwide, and elsewhere in the US may also be a pest of greenhouses and other indoor areas where tropical plants are grown .

Reproduces through parthenogenesis in the US, where no males are found. It has two sexes in some parts of the world (Europe and Indo-Malaysia), though. Unlike many roaches, the egg capsule is retained inside the female's abdomen until young are ready to emerge. Usually described as giving birth to live young, however Modern Pest Services site below seems to show that the egg capsule is ejected from the female.
