We have the same probelm in our greenhouses. There are a couple of
things you can try that shouldn't injure your plants:
1. Try a product called Safer soap. It should be available at Target or
Home Depot or such. It's about $8 a concentrated pint but I think it's
sold ready to use also. It's composed of fatty acids.
2. Utra fine or super fine oil spray is used in some greenhouses here
and some people swear by it. You should be able to get it from a
horticultural supply house.
3. Enstar is the insect growth regulator used to control whiteflies but
I think you need a license to get it.
4.Commercial greenhouses often use very fine netting to protect their plants
5. Parasitic wasps - I have the name of a local supplier if you
want but they are more work.
