I haven't had this problem before, but this year my iris leaves are just covered in whiteflies and I have lots of irises. And there's that sticky gooey white stuff all over the leaves with their eggs and some of the leaves are yellowing as a result. I sprayed my homemade insect soap on them two weekends in a row and it doesn't seem to be doing any damage. I wondered if anyone else has had this and wondered if there is a soil problem that might be underlying their unusual numbers... or drought problem? And are whiteflies only an early summer problem or do they stick around all summer long?
I've started using some extra yellow sticky traps I had laying around but I get worried about catching good bugs on those sometimes. (I once caught an anole in a sticky trap going after his lunch. Doh!)
