Due to my mealybug infestation, I will never be growing outdoors (or in my greenhouse) ever again. I have sprayed with Azatrol regularly up to and throughout flowering and it doesn't seem to slow them. I've tried the alcohol rinse and that didn't work either. Can't do it while my buds have resin on them anyway. Can't freeze em out because i'd have to make my greenhouse too cold for the plants/fish/turtle. Its so bad that one of my plants that has been flowering sinceJuly 21st now SMELLS like mealybugs. Its disgusting. All of my harvests from the greenhouse this year have been infested with mealybugs. Even if i pick them out manually, ill never get them all AND it still leaves behind their mess. Hash, anyone?

Have you tried introducing predator mites into your greenhouse/garden area?

There are means of chemical control, but I'd try getting some good mites and letting them loose. I think you might also be able to try lady bugs (australian ladybird beetles i think.)
