Beetles in the basil

[joeysmama]

I grow basil, and other herbs, every summer and the basil always does very well. But this year beetles got into it. They didn't touch the parsley which is in the same pot, or the other herbs in other posts, but they destroyed the basil.

My husband suggested I spray it with something but I don't want to do that. I think I have to just tear it out and plant again--it's really crummy. But how do I keep it from happening again without using pesticides ??
