Sugar water and borax is the best answer, if they are aphid ranchers.
Get you glass and examine the ants closely.
Look at the mouth parts, Carpenter ants have large, strong mandibles and will ignore the sugar water.
If you put a drop of isopropyl, (rubbing ) alcohol in it, and then plug the hole with putty, they will go elsewhere.
And then there's predator ants.
They, move fast, and have sharp, pointed mandible for seizing prey.
They actually hunt down and eat aphids.
We have them here, they were imported from south America to eat cane borers.
If you have them, count your blessings. But be aware, they are meat eaters and will take a bite out of you.
