The Western harvester ant is found in the west at high elevations. This is a red colored ant that can be 6.5 to 10 mm long. Galleries have been found to go over 600 cm deep.

How Did I Get Harvester Ants?

Flat, open and sparsely shaded lawns give harvester ants room to build their mounds, plus these ants generally prefer to build their nests in sandy soil. Since seeds are a major part of the harvester ant diet, gardens or bird feeders may also attract these insects. Harvester ants tend to avoid indoor areas, but sometimes enter homes by accident through cracks and gaps around windows or doors. Harvester ants are very large and robust.

How Serious Are Harvester Ants?

Harvester ants are an outdoor nuisance, especially in backyards or recreational areas. Many species of these pests can deliver painful stings and bites, but are not considered as aggressive as fire ants. However, a harvester ant sting can last longer than the stings of other stinging ants, and allergic reactions can be serious. Their mounds cause unsightly barren spots in lawns and landscaping.
