Hey Don,

It sounds like they might be carpenter ants.

Here’s a good article about them…

They like easy entrances and heart rot is perfect for them. The ants didn’t cause the rot. They just take advantage of it. Keeping ants out of trees is easy enough with a painted zone on the trunk, but heart rot often goes to ground level or into the root ball at the base of the trunk and can go up the main trunk quite a ways.

Hey Mark,

What do you mean by a painted zone? Just standard issue paint, painted around the trunk?

Hi Duncan, it’s a special sticky sort of glue/paint/ band that you either paint around the tree trunk or stick around the trunk. The ants get stuck on it and physically can’t move any further.
Also always remember to paint your cut wounds with milk after pruning. It stops diseases and insects from entering the open wood.
