I have 2 pear trees in the back of my yard that get Japanese beetles in them every year. We don't eat the pears, but the chicken love them. This is the first year I've had ducks and the last couple of nights right before dusk the ducks go back to the trees and pig out on Japanese beetles. My DH even gets a pole and knocks them out of the trees for the ducks to get. It's fun to watch them enjoy themselves so much. I hope they don't get too fat from them. The beetles are sort of a bedtime snack as this is usually right before I put them in the their pen. My little pest control company. I'll try to get pictures tonight.
