That's a flea beetle.

I agree..flea beetle. They usually have little holes all over the leaves. With my own research, It doesn't harm the plant at all and make sure you just wash your leaves well.

I hate flea beetles. I don't have issues with them each year but when I do, they do a world of hurt to various brassicas like my mustards, tatsoi, chinese cabbage and more. Never seen them go after basil though.

Thank you! Now at least I know what I'm dealing with. I'll sniff around for a solution, and try the garlic spray anyway, as some sites recommend it.
Fata, my two basil in the upper flower garden are infested with them, and so far the lower veggie gardens - also with more basil - are pest free of anything, but that will change, as we all know. Do you have any pest control ideas that don't involve large cash outlays?

You could try planting some radishes to trap them in and then use sticky traps among the radishes or spray the radishes.
