I noticed that on my blueberry bushes that are starting to turn ripe, the berry are shriveling up and falling off before they become fully ripe. There are dozens of shriveled blueberries laying under the plants. While discarding them I notice little holes and after inspection I found worms in them and I am certain it is maggots from fruit flys.

I sprayed some Seven because thats all I have that says it works for them. It says to wait seven days after spraying to pick. Will the berries rippen and fall off in that amount of time? Is there anything else to spray them with that has a shorter wait time?

All the solid green berries look great but as soon as they start to turn color they get that littl hole in them.
