my angel’s wing has mealy bugs!! i have isolated it and am routinely inspecting/spot killing with diluted rubbing alcohol. i’ve also added bonide systemic granules to the soil. is there anything else i can do? I haven’t seen any of the cottony egg sacks, but i’m keeping an eye out to kill those too. i feel like just spot killing will keep me behind, like playing whack a mole. also, are these brown things on the stems normal? they kinda come off with some force and rubbing alcohol…
