Pest description and crop damage Ants normally establish their colonies in sunny locations in well-drained soils. In turf, a nest consists of a series of underground tunnels and galleries which may extend three or more feet beneath the soil surface. Multiple openings provide access to the surface. During nest construction, ants excavate large quantities of soil which they deposit in mounds on the surface. Not only are these mounds unsightly, but they can smother the turfgrass immediately surrounding colony openings and make routine maintenance difficult by producing a bumpy, uneven turf.

Biology and life history A typical ant colony consists of an egg-laying queen, males, immature stages (eggs, larvae and pupae) and hundreds to thousands of sterile female workers which can become a nuisance as they forage around buildings, sidewalks, foundations and driveways. Ants consume a wide variety of foods including seeds, small insects, plant sap, flower nectar and fungal growth. Many ant species feed on honeydew, a sweet liquid secreted by plant-feeding insects such as aphid, mealybugs, scale insects and leafhoppers. In the spring and fall, colonies produce winged ants that leave the colony, mate and seek new nesting sites.

Management-chemical control: HOME USE

Effective ant control normally requires destruction of the queen. In most cases, this necessitates one or more applications of a liquid or granular insecticide. In situations where only a few colonies are present, apply insecticides directly to colony openings and the areas immediately surrounding the mounds.
