NC Whitefly Parasites 500 (Encarsia formosa)
Vendor: NATURE'S CONTROL
Item #53-120290
Tiny Whitefly Parasites (Encarsia formosa) lay their eggs inside developing Whitefly pupae, so a Whitefly Parasite hatches out instead of a Whitefly. You'll need a magnifier to see them, but they spell death for Greenhouse Whiteflies, and they provide some limited control of Sweet Potato Whitefly as well.
