How To Identify a Harvester Ant

Harvester ants are ret to brown to black in color. They are a larger ant; 1/5 to 1/2 of an inch long. They have two nodes (bumps between the middle and rear body sections). The workers of harvester ants vary in size. Harvester ants have a row of long hairs on the underside of their head. They may also have spines on the back that are sometimes present. 

Where Do They Come From

Nests of the harvester ants appear as flat, bare, circular patches of soil averaging several feet in diameter. Their nests may be several feet deep as well.

How To Keep Ants Away

  • Trim back any shrubs or trees that come into contact with buildings. When plants touch a home or building they create an easy way for ants to crawl onto and access the building.
  • Seal all potential ant entryways. Common entry ways are around windows, doors, and utility lines.
  • Keep dry pet food in sealed bins and clean up any spills.
