What do Field Ants look like?

When you first glance at a field ant you may think they look like any other ant, but they actually have a segmented body that is distinctively uneven on the upper side. Adults will grow to be 1/8 to 3/8th of an inch in length. Field ants can come in a variety of colors that include pale yellow, black, reddish-brown or a combination of colors.


What are the signs of Field Ants?

Field ants feed on other live and dead insects, honeydew produced by aphids, and food commonly found in homes like sweets, liquids, and meats. Field ants get their name because they are more often than not living and nesting outdoors. Outside field ant nests are found in fields, lawns, meadows, and along sidewalks, building foundations, and fences. They will dig the soil out of the ground to create their nesting area and will mound the soil on top of the nest.

Field ants typically only become problematic in the late summer after the reproductive females swarm from the colony. Field ants typically only enter homes to forage for food and rarely create nests inside homes and other buildings.

What Damage do Field Ants cause?

Field ants build large, tall mounds on your lawn that make mowing hazardous. They also inject acid into your lawn which could create long-term damage to your landscaping. These colonies can survive for 10+ years growing larger over time.

How do you prevent Field Ants?

Listed below are some tips to deter field ants:

Keep trees, shrubs, and other landscaping trimmed back from the exterior of your home.

Create a barrier between the foundation and any mulch or grass.
Seal any cracks or crevices found in the foundation or exterior walls.
Install door sweeps on all exterior doors.
Store food in the refrigerator or in tightly sealed containers to prevent ants from gaining access to it.
Regularly sweep floors, and quickly clean up spills and crumbs.
