Well, yes, you'd want them out of your garden area just so that you don't get bitten by them (if they are the biting kind).

Even if they don't bite, for me, I don't like things (lots of things is even worse) crawling on my hands and arms when I'm doing yard work.

Since you mention specifically that they are different kinds of ants (with wings), then you'll need to check what kind of food they eat to get the proper bait or food to trick them and remove them. For example, something sweet or something else?

You can also keep that bed area constantly wet and see if they move on their own but then when they do move, you'll have to handle them at their next spot also.

Another discussion about this same question just a couple of threads down the page.
