The brown-banded cockroach has a fairly wide distribution, being found in the northeastern, southern, and midwest regions of the United States quite commonly.

In an experiment by Tsai and Chi they found that populations of brown-banded cockroaches would be expected to thrive in environments with a temperature between 25 and 33 °C.

In an experiment by Cohen and colleagues they found that the larva of the brown-banded cockroach when given a choice will choose a casein:glucose ratio of 15.5:84.5.

[7] In Prakash and colleagues experiment they observed that the curved edge of fifth segment that remained most ventral and probes the substratum with it during foraging.

[7] On the fifth segment parallel to the curved ventral edge on the medial surface is a longitudinal furrow that's densely lined with papillaform sensilla.

[7] The shaft of the papilla has a longitudinal slit near the distal tip, allowing dendrites of the sensillum to sense the external environment.

[10] According to Schal and colleagues the site of sex pheromone production in the female Supella longipalpa is located on the fourth and fifth abdominal tergites.

[11] Each pore is connected via a long duct to modified epidermal cells, suggesting that these structures are involved in pheromone production.

[26] Smith and Schal found that ventral nerve cord transections, either immediately following copulation or after odthecal deposition, restored calling in mated females.

[27] Their experimental evidence suggested that termination of calling is moderated neurally by a two-stage process, initiated by placement of the spermatophore and maintained by the presence of sperm in the spermatheca.
