As National Sales Representative of the Cockroach Institute of America
(CIA), may I suggest you select either of our excellent choices, the
Hissing Cockroach or the Hissing and Spitting Cockroach.  I would
suggest if you choose the latter, you should try it out experimentally
first, before you make a large purchase, as cochlear gumming is one of
the lesser contra-indications for this species.

Best,
