I seem to have tiny, pests, on my sweet potato vines (in the house).Look like tiny drips of moisture on the leaves mainly, both top and bottom. NO IDEA what they are, or how to kill them off permanentlt! I can lightly squeeze the leaf and it seems to kill a lot, but not all. I did wipe them down with a Q-tip dipped in rubbing alcool, and that did kill the ones it touched ( look like tiny brown specks on the leaves)...but that also did damage the leaves a bit. Considered wiping down with thinoil, but worried the plant will suffocate. Also wondered if I can totally immerse the cuttings in alcohol safely to get rid of them...Anyone know what I am dealing with and how to stop permenently???
