I battle the mite plague-the 2 spotted kind-Can't tell from the pic if the spots are white or yellow. If they are white you got the mite.if they are yellow stay mellow, and they can be very! hard to see. The eggs are miniscule, clear to white , and usually you'll see a lot of them especially on the sides of the main stem of the leaf. When they hatch, even under a magnifier, they look like white fluff, hard if impossible to see moving. Then they are clear bodies with 2 spots, 1 on each side . At this stage you can see them move. At adulthood without mag they look like specks of pepper or even smaller. so go to Radio Shack and get their 3 stage loop-I think it's 5x,10x,and 15x for like $8. Sraying with water, alcohol, doesn't work. I try to use OMRI rated pesticides and have had luck with Sucrashield, but you have to keep up-you can spray every day if they get bad, but after they're under control I usually spray once a week. Bought the sucrashield on the net in a small bottle (I think 12-16oz for like $20 or so-very reasonable). Hope this helps and good luck.
