Neem is said to throw off their breeding. need to spray a few times as eggs hatch. seems to work for me. white fly likes hot and dry change that if you can.

Subject: [permaculture] White flies in the greenhouse


After reading the aphid in the GH thread, I thought I would ask about a
similar problem I am having, white flies.

White flies tend to be a persistent problem in my GH, worse in the
warmer months, almost disappearing in winter but they always reappear
the next spring. I've tried various things: yellow sticky cards, soap
sprays, etc but nothing seems that effective for any length of time.
Without continuous battle the white flies quickly rebuild their
population levels.

Any thoughts about control methods or predators that would be effective
in a year round cool temp GH?

TIA
