Black Walnut Flies
Hello, My property has numerous black walnut trees. I have lived here for 15 years and each year some trees have produced more walnuts than others. Flies have always be a pest. But this past year we had an abundance of nuts fall from our younger trees. No more than from what we have experienced in the past from our mature trees. But this year along with the high volume of nuts we had a disturbing amount of flies. I should say an unbearable amount of flies. Is there a way to control this in the future? I know the flies find a love to reproduce in the husks. I am getting ready to tap the trees for sap to make syrup and also am interested in utilizing the husks for medical purposes. The nuts are very good for you as well. Do you have any recommendations on how to get rid of the flies? I understand that they naturally are drawn to these trees but since we have lived here we have seen the lady bug invasion, stink bug invasion and now the fly invasion. One can only stand so many bugs. Any recommendation will be appreciated.
