Hi all, And here I thought I had managed this entire inter with only irritating fungus gnats as my enemy. But now, when watering one of my meyer lemons, I found a cottony cushion scale. Disgusting thing, made my skin crawl (not the biggest lover of bugs!) The question I have now, is what do I do? I got it off the plant, and will be closely inspecting all of my others. I don't have access to horticultural oils (only cooking oil ha ha) any idea what I should do?
