Distant: Ant mounds are only a problem on golf course tees, greens and fairways, or where turfgrass is mowed very short (< 1.0 inches). Ant mounds are undesirable on tees and greens because they interfere with putting and may be unsightly. In addition, stepping on ant mounds, or running over them with mower wheels may result in ½ to 1.0 inch diameter round patches where the turf is covered by soil.

Up close: Round-based conical mounds about 1 – 2 inches in diameter with a hole in the middle. They consist of finely ground soil or sand. Ants can be observed coming and going when the temperature is 60 °F or warmer. The mounds are most obvious if the area has not been disturbed by mowing or irrigating for several hours.
