The beetles do not bother my raspberries because I have a ton of wild grape on the property and they seem to prefer the grape .
However they will go after my peaches and I use a spray of garlic pinch of pepper (any hot pepper will do ) and teaspoon of honey
2 cups of water
1/2 cup chopped garlic (or garlic chives)
1/4 tsp pepper
1tsp honey
Put through blender
strain through cheese cloth
and spray
It has saved many bushel of peaches from the nasty hungry bugs.
Of course it is best to wash the fruit before eating
