Was just curious if I'll see left over ootheca or any telling signs besides tiny nymphs.
Any advice/help is greatly appreciated!
I only quickly glanced the responses, so perhaps I missed something but...
You don't have any adults? Nymphs don't breed and it takes them upwards of several months to reach breeding age.
You should have adult males and females (Males have visible wings, Females don't). 1 male: 2.5 females is a ratio I use but you can experiment; you don't need 1:1. With heat (80F+) they breed within a month; you can usually tell by a huge burst of tiny guys.
IMO, you should have crystals for them (no standing water). Orange slices or similar will work but you have to keep them fresh and its just not wroth the hassle compared to water crystals you "set and forget".
