Every year usually make close to 100 jars of raspberry jam. This year the gooseberry bush was infested for the first time by red currant fruit flies also known in there earlier stage gooseberry maggots. We ended up losing the whole gooseberry bush and it also wiped out the entire raspberry patch, going to have to double down on the wild huckleberry jam. Wondering if anyone else has dealt with this problem before and what they have done. Any tips would be greatly appreciated.
