I have one lemon tree and one lime. White flies are a problem here. I mix a little Dawn dish detergent with a little Listerine Mouth wash and put it in a spray bottle with water to fill. I spray it on the trees when they have no flowers and the white flies disappear. If there are buds I hand wash each leaf rather than spraying. So I decided to try it on my Nun Orchid that had scales…they died in place. At first I thought it didn’t work but then I ran my hand over them a couple of days later and they just fell off. Listerine by itself may be used on the roots of orchids and I knew soap water keeps sap sucking insects off plants. From what I have read neither one is considered a pesticide so I mixed them together and it is very effective.
*Note: This was my own experiment. I have never seen bees on those 2 trees so I felt comfortable using the concoction.
