I have carpenter ants in several trees on my property. Visible signs - large weeping areas, wood pecker holes, chip piles, and trees splitting. When I cut one that has split I get piles of ants. How can I kill them/stop them from spreading to other trees? What are my options? 1 acre wooded area.
Carpenter ants are a essencial part of the natural decomposition process for the wood. They generally prefer wood with a certain level of decomposition. It looks like you wooded area is the ideal environment for these ants. Best think to do would be removing as much as possible the rotting logs and other places where there ants are nesting so that you decrease the suitability of the environment for these ants.
