Ant Facts, Identification & Control

Group Name


General Information

Ants are insects that belong to the same group as wasps, bees and sawflies. Ants, however, all belong to a single group called the Formicidae; it contains roughly 11,000 species. These species can be easily separated from wingless wasps, because ants have one or two petioles; a petiole is a node-like structure found on the “waist” of ants. Although there are wingless wasps, most wasps lack any such node on the waist, making the waist appear as only a small or thin connection. Knowing to look for the petiole allows one to determine if an insect is an ant or not. One other point is the antennae are always elbowed in ants (not always so in wasps).

Ants are truly social insects. They have cooperative care of young, reproductive division of labor, meaning work is done by non-fertile females and overlapping of generations. The success of ants is attributed to their community building skills. Ants strongly influence the functionality of ecosystems. Ants dominate by their massive biomass, manipulate species composition, influence food webs, possess numerous mutalistic and symbiotic relationships.  Ants shape both the non-living (by moving soil) and living (plant- ant mosaics) communities..

Considered by many to be one of the most successful living things on the planet, ants often come into conflict with humans. Ants invade our homes, steal our lunches, infest houses and at times inflict pain. Ants range from mildly annoying to highly problematic. Knowing what species of ant one is observing in conjunction with its biology and control can help to manage them successfully. When controlling ants, it is important to locate the colony; inspection and persistence are the keys for effective and successful management.
