H. subcincta not producing nymphs?

[recluse]

I have had these for a while now through a trade with Dave Grimm, I have increased temps. and humidity but still no nymphs, any help would be appreciated. Thanks in advance.

Do you mean the roach species Lucihormetica subcincta? if you keep them in good conditions they should produce nymphs eventually.
