So we typically find a few tents per season, less than 10 a season for sure. I'll be honest, I've gotten away from spraying since I started planting fruit trees. If I do spray it's typically reactionary spraying. I dont have time to do it, and, I just don't like spraying the chemicals into the environment. We spend a lot of time establishing native wildflowers and plants and pollinator habitat in general, so I feel spraying goes against one of our primary habitat goals. I have focused on disease resistant varieties and this is a wild life orchard, I dont really care what the fruit looks like.
I wouldn't mind looking into a more earth friendly spraying program if one exists and I find more time in my busy schedule, but frankly i just dont see that happening anytime soon.
For now, I cut them out where possible or scraped them off. Ideally i would have hauled them off and burned them, but there was close to 14" of snow on the ground so nothing was easy yesterday, I just tossed them on the ground. Hopefully they turkeys and other migratory birds find them and eat them if / when they hatch.
