They keep coming back! My poor Christmas cactus has had a hard year. I have quarantined it several times, washed it down, removed all of the little fuzzy bits I can find and yet it returns! I've had it! My poor plant is on the back porch right now, and it's very sad. I've had this plant for 20+ years. Help! (prefer to not use poisons... but might be desperate enough if it's not too awful.

Well i know just the thing that will lengthen your plants life and keep the bugs away.Unicorn blood will do the trick, just find or breed some unicorn and DRAIN'EM.......DRAIN'EM DRY!!!

It sounds like you have already tried the soap and water method. Have you tried a little rubbing alcohol on some Q-tips? Rub this on all exposed surfaces. I would give that a try, but if all else fails, you could get some insecticide. Go to your garden center and tell them what kind of incects you have.
