I have purchased them from lowe's & Home Depot. Actually I had a miniature rose bush that the same bugs got to. Yuck! So Mealy bugs huh? Yummy! *lol* They are flat, oval like shape, grey little buggers! So do you think that the insectiside could have caused the leaves to yellow & die? Or is that something else I am doing? ;) I know they should be in a shallower pot, I used cactus mix & I only water when dry, could it be too much water? I know that will sometimes cause plant leaves to yellow. Thanks so much everyone!! This site is great!! I could have saved lots of poor plants this way!! hahaha!!
