I did a few searches as well and this was one of the concerns I found:
Zebra Roach (Eurycotis decipiens) -- A strikingly patterned roach, about an inch and a half long, that is native to Central America. It is a fast runner and has tiny claws on its feet which allow it to scale glass or smooth plastic, and is therefore difficult to keep confined. The zebra roach also releases defensive chemicals when disturbed that many people find offensive.
Depending on the chemicals, probably doesn't look like a good feeder.
