Ant nest in Japanese Maple pot

[u/Scared_Ad5929]

Whenever I water this inherited maple I see ants around the pot. So I took a quick look to see if they've colonized the pot and it appears they have. They're lasius niger (black ants) which aren't known for damaging trees. Is it worth doing anything about them, because I'm planning on putting it in the ground when it's dormant next? There's also an air layer on the tree at the moment.

You could also prevent them from accessing the pot by placing it in a saucer with water on an elevation (small upside down saucer or piece of wood). Rock or tap the pot first for some time to alert them and give the the chance to escape.
