tiny white worms in fall bearing raspberries

Question

Is it ok to use neem oil on fall bearing raspberries to eliminate the tiny white worms on the berries. Can we use the berries after spraying, or how long would we have to wait to use the berries after spraying.

Answer 1

Neem oil will leave an oily residue an a bitter taste. And may not be effective for contact knock down.
I would use the botanical chrysanthemum extract called pyrethrum or pyrethrins, which biodegrades in 12 to 24 hours with sunlight. After which you can re-enter sprayed area and harvest berries. Wash thoroughly before eating. (Not to be confused with the synthetic chemical version called pyrethroid which is effective but has a longer residual presense and should not be consumed for a month or more.)
