How to protect red raspberries from yellow jackets?
I have a very small patch of red raspberries. Not enough to share with the local wildlife. Yellow jackets have been a problem. I was finding that my berries were 1/2 eaten by something. The bottoms were gone. The remains were doughnut shaped. As it got worse, I found yellow jackets with their heads burried in the berries and their back ends sticking out. By the end of last season, there were so many yellow jackets, I couldn't even pick them anymore. Seemed like every berry had a yellow jacket burried in it. At that point it didn't matter because the berries were pretty much ruined.
Any suggestions on how to save my red raspberries from yellow jackets this year?
