It isn't that distinct rough pattern that you see in Surinam cockroaches. Also, this is why looking at just one character can be misleading. Check out those cerci, see how big they are? Surinam cockroaches have much smaller cerci. Another thing, Blaberidae don't have spines ( or have a few very small spines) on the prothoracic femora, where as Blattidae have a row of subequal spines, and Blatellidae would have a row of varying sizes. Pretty sure on that ventral pic I can see a row of subequal spines when I zoom in.

Oriental:
Surinam:

Appreciate that response; I've never found any information on the differences other than that one feature.

Lots of characters to keep straight with insects :)

Because my Mom has a service contract with Terminix, and the woman that came out said to her "Just be glad they're not Oriental roaches." She said that she KNEW they weren't because the "oriental roaches are red".

Most roaches are not pests of homes, just got lost looking for food and wandered in. Oriental roaches can be varying shades of red, black, reddish black. They feed on decaying organic matter so that's why you find them all over. Actually very helpful to the planet, it upsets me so many people dislike them.

An old unused greenhouse that they began in (I believe). There were some old paper bags from maybe charcoal that sat in there and the greenhouse kept them moist. Once the greenhouse came down, all bets were off! That's when they moved in, mostly into the garage but occasionally into the house. Thanks for the ID Natalie! Much appreciated!
