Whiteflies have me on the verge ...
... of doing something really drastic.
I cleaned and fumigated the greenhouse this fall, and cleaned & treated all plants before placing them in there. Nevertheless, there they are again. Between last year and this, I've tried sticky traps, insecticidal soap, neem oil, di-syston systemic (Bonide) and cyfluthrin (Bayer), but they seem as abundant and as healthy as ever.
I'd really like to get this problem under control before I start my seeds.
Does anyone have any advice, anything that's worked for you ... short of nuking the whole greenhouse and its contents?
Thanks in advance,
