Dubia roach colony dying.

[Jolan]

So my dubia look like they are recovering nicely. I looked through there bins last night and found only fast moving healthy roaches. I estimate I lost about 10% maybe a little more and mostly adults and sub adults. The bin that had nothing but adults (my new breeder bin) got hit the hardest. Sure wish I knew what happened, so I can avoid this in the future. Thank to everyone that replied.

stagger your egg crates and make sure the ventilation is on point?

I keep dubia, hissers, and giant caves and have for several years with only the occasional issue.
