Most species of harvester ants are red to reddish brown and monomorphic (6–8 mm). These ants are easily recognized by their psammophore or beard under the “chin,” which is used as an aid in digging for seeds. Harvester ants nest only in sandy soil of a particular texture. Ordinarily these ants feed on seeds of grasses and various weeds, but they can also be a problem in alkali bee beds. Reproductive swarming occurs in spring.

Primary Concerns with Harvester Ants

These ants are among the few in the Pacific Northwest that can give a rather severe sting, somewhat like a honey bee or yellow jacket. Since the greatest number of colonies of these ants occurs along the Snake River and Columbia River areas, people who are stung are usually engaged in picnicking, fishing, rockhounding, or other recreational activities. This is usually not a serious pest, unless there is an allergic reaction; few people are stung.
