4613 Ant hill nest

We bought a house last year and found we have carpenter ants outsized all over the place. We think we finally located the parent hill. A giant three foot ant hill hidden in the brush. Your site says to physically remove it? How do i do that ? Do I use any thing to kill them off when they start to swarm out?

Carpenter ants build nests by burrowing into wood. They do not build ant hills.   Thatching ants build ant hills.  There are some control suggestions on this web page:  http://pestcontrolcanada.com/ants.  Thatching ants can be considered beneficial because they kill other garden insects pests.
