Buff Gardeners

I have 2 raised beds and the ants love them. Anybody know of a food-safe way to eradicate them? I usually pour a teakettle of boiling water on them, but it isn't long before they are back.

I welcome you all to the group, sorry I lost track as to who has recently joined. But I will try to keep up on the posts, but have to admit that we are going on vacation next month and will probably fall behind again. Anyway, glad you are all...
