Strange things happening!...
My adult crickets are dying while my babies and juvs are fine.
The adult's criket belly turns pale black and then they die

I have cleaned their container, their water and feeding devices, but nothing, every day was counting 5-10 died crix.
What could be? Probably an old virus that killed many crix in the past or maybe inbreeding problems?
But then again...the babies are fine?...
