I have several places in my yard with a lot of ant activity. It is clear the ant colonies are in the ground where it is bare and void of grass or other growth. I’m fairly certain these are field ants but would like to confirm to before beginning any mitigation. I have attached a few pictures of an ant that will hopefully be good enough to aid in identification. I would guess the ant in the photo is about 1/4” in length. Thank you for your help!
