I have been having a terrible time with mealy bugs in my greenhouse.
I have tried Neem oil, but it doesn't seem to slow them down at all! I have also tried a systemic imidicloprid made for citrus (the Bayer one), but it is still an ongoing battle.
What kind of horticultural oil do you use?
I get so confused when I read the labels. Is it different than dormant oil? The guy at the store said to be really careful with "heavy" oils or I can kill the plants, too. Also, I was told not to use it in my greenhouse because of the high humidity and sometimes high temps (up to 100 in the summer, but it IS shady and the fan is usually going...).
I have birds flying loose in the greenhouse, so I also don't want anything that smells really strong. They don't chew on the plants, though.
My biggest battle is with my citrus and coffee.
Or should I just keep using rubbing alcohol?
Thanks!
