Please Ursula next year try BigBill's preventative "little bad beasties" program!! It might help.
I use Neem oil, dish soap in a gallon and a half pump sprayer once a month as a preventative. I soak the plants early in the morning, undersides and top sides. The nozzle adjusts to a fine mist. You could do it May 1st through October 1st outdoors and maybe knock these little crumb buns back before they come inside. Then you can spot treat all winter.
I do Neem oil once a month year round and I must say, 98% of these little buggers are gone. Mealies, thripsters, hipsters, gnats, bats, homeless people
are not seen in my Orchids! No scale either.
Please try it! It's like chicken soup, it can't hurt.
