What To Do With Ant Mounds?
Q: I have two bare spots in my bermuda lawn where ant mounds have disappeared and a third hill that’s still active. What do I do with the hills?
A: Dilute a liquid lawn insecticide according to label directions and pour a pint into the mound. This will usually kill all the ants within. You can then plant three-inch diameter plugs of bermuda grass into the bare spots. It’s usually easy to find places where the grass has overgrown the edge of a sidewalk or driveway. You can dig out the plugs there. I am guessing these were fire ant hills. Make a note to treat the lawn with fire ant bait (Amdro, etc) next May to poison small mounds you don’t see now.
