Anyone ever dealt with flea beetles?

[LauraMoser]

I'm pretty sure some have started to eat the leaves of my potato plants. Boo. What can I do to get rid of them? And I read that the larvae will eat holes in the potatoes in the ground. Is there anyway to try and keep that from happening? Will they damage my potatoes so terribly that I can't eat them?

This is only my second attempt at growing potatoes, and last year I had no bug problems. Ugh.
