Patti- the flour only works on the baby bugs, though. When they are still soft bodied. I still squish the adults that I see, and scrape the eggs off to keep them at bay. I feel like this year we drastically reduced our numbers and if I keep on top of it, we'll be ok. Just wanted to warn you that it wouldn't kill them adults.
Shoe- I hear you with the war. That's what the farmers here do- work with them until they just give up, but getting a fair harvest in the meanwhile.
