I have a robust (table) grape plant, but something is picking
off the immature grapes as they first bud. I had ants walking
on the plant up to a few weeks ago before the buds emerged.
I killed them off with ant baits located on the plant and
on the ground. The only pest I've seen now is a couple of
bound-up leaves with caterpillars inside. I've been able to
kill all of them - there were probably only ten so far.
Occasionally, I see some wasps flying around. Any help is
appreciated.

It's normal for the small grapes that came from flowers that didn't get
pollinated to fall off. On mine, some of the tiny grapes fall off the
cluster leaving most of them to continue on. Could this fit what you are
seeing?
