Mealy Bugs =(

[Zoey339]

Hello,

I have a fairly large collection of Phals. I noticed 2 days ago one was dropping leaves. On inspection I found tiny mealybugs around the leaf joints. I unpotted the plant. Cleaned it the best I could with alcohol, boiled and clean media and pots. Just to find an adult mealybug on one of the flowers after. Maybe it was dead? Since then this morning I found an adult on the plant next to it and a nest in the roots on the plants next to that one. I'm looking hard to find them, they aren't very noticeable. Help?? Repotting everybody is really not feasible. First reason rubbing alcohol is very hard to find now a days and I don't have enough to treat 30 orchids. Second I have a tenancy to kill orchids when they are repotted and some are not in the best shape already. Is there a easily solution? Like an insecticide to add in the water would be super!
