I have a serious infestation of asparagus beetles in my patch. Should I remove all of the rotting leaves now and replace it with straw since I read that rotting leaves encourages the bugs? If the infestation is really bad should I dig up my entire patch and start over next y to ear? My patch is about 5 years old now. I have never seen anything like this before and am greatly distressed about it. Did I do anything to encourage these beetles? Thank you kindly.
