Japanese Beetles On Eggplant

Should be about 3 weeks until they start up here (knock).
Sevin dust is incredibly effective on them...
Eggplant, pole beans, okra, summer squash...tough to say which they like best. There is a time of day when they seem easier to knock into soapy water and kill. I want to say an hour before dark? But I wouldn't swear. I will have it back in current knowledge next month. But there are conditions where they are sharper and harder to kill.

I don't think japanese beetles are like doves or ducks that smell the food on each other on the roost and then follow the most well fed birds back to the good fields. At least I never thought of it that way. I don't know where the beetles go at night, but I doubt they roost up in bunches like birds!?

Edit I still think the worst thing to do is put up those beetle traps. That calls them in from a huge distance and they won't all go the trap if you they have tasty leaves to eat.
