The soil in my raised beds is alive with worms and by mid summer the soil is covered with worm castings and it has made no difference in the whitefly population. As a matter of fact they seem to be worse than years ago when I didn't have nearly as many worms.
I have tried everything to slow down the whitefly population and have found nothing that works for very long. My best results have come from spraying with various things like dormant oil, mild poisons, soaps, essential oils and simple water sprays and alternating them. I only use poisons when the population becomes unmanageable.
If anyone finds something that really works on a heavy population of whiteflies I would love to try it. The last 3 years have been a constant battle from mid July til cool weather arrives in November.
