anything marked for white flies will do it..you'll not likely be harvesting for awhile now...so you can use most anything
posion.. or the suffocating neem oil .. just soap and whaterin a sprayer helps... doit eaarly or late.. as the oils can burn the leaves in full sun..

the most important thing is to spray regularly -- every two or three days, -- for a couple of weeks, even if you don't see any more bugs. Otherwise, eggs will hatch and start the cycle all over again.

Hopefully all this rain will help knock 'em down, too.

Death to whiteflies!!!
