Just noticed small brown worms on the underside of the leaves. Picking them off by hand but what are they and how do I control them.? They are destroying the vine! Thank you, Annie East China MI

Without a picture it is hard to guess. The timing is right for grape flea beetle. The adults are small beetles out early in the season and you are seeing the larvae.
I attach a picture of the larvae.
A stomach poison such as Sevin should kill them pretty quickly
