Hey are they black bug or small black pods that are on sps are they moving quick when you flash them ?All of the acros are affected you just might not see it with the naked eye.
I believe there cycle is 7-10 days to hatch or something like that. Thats why 3 treatments are required. The treatment will not kill eggs so until they hatch you cant kill them .
Quarantine is great but you still need to do 3 treatments to kill them in dt or quarantine
