Pick up all walnuts that are maggot infested and put in bucket of water. Do not leave any of the shucked maggot husk out there because they go into the ground to pupate and stay in the ground till late June and then home out and turn to flies that lay the eggs in the walnuts. The population grows with every year till they get all nuts. I used to put a bug zapper under certain trees every year and it helped a lot.
