RASPBERRY MAGGOTS

CAN SOMEONE TELL ME WHAT TO SPRAY RASPBERRY CANES WITH TO STOP THE MAGGOTS IN FRUIT & WHEN TO SPRAY THEM PLEASE.

ALSO WHEN IS THE BEST TIME TO PRUNE THE CANES.

Daintiness answered the spray/maggot question for you last year-did that not help?

If they are summer fruiting you should remove the old fruiting canes after cropping-autumn fruiting ones you cut hard back around now
