Pest Ants of Alabama [Alabama Ants] [Alabama Exotic Ants]
The following list of pest species includes 57 species. This list includes species that are considered to be serious pests, in that they may cause significant damage, health problems, kill small animals, or disrupt ecosystems, to mild, nuisance pests. The most serious pests are prefaced with a (*) symbol. Some of the species listed are seldom encountered, but when they are, they may give painful stings. This is the case with the army ants listed (Neivamyrmex spp.). Although we infrequently find them, they are aggressive and may inflict a painful sting. Not all ants that sting are listed as pests, because many of these are non-aggressive, however, keep in mind that if an ant has a stinger, it can sting. Likewise, many species can bite if provoked, but not all of these are listed. Additionally, there may be occasional species that bother mankind in various ways that are not listed. The pest status of some of the listed species, such as Cardiocondyla spp., is questionable, and their negative effects may be more that they compete with native species. Many of the species from this list were included by Smith (1965) as pest species in his publication entitled "House-Infesting Ants of the Eastern United States."
Clicking on a species name will lead to a page with further information and photographs of that species. Although species pages are at various levels of progress, most pages now have representative photographs of at least workers of the species. In addition to the photographs of ants taken by Joe MacGown at the Mississippi Entomological Museum (MEM), many photos are used, with permission, from AntWeb, a web site about ants of the world with amazing photos. Another site with photographs of ants is "Discover Life." The Discover Life site provides a list of North American ants with photos at "Kinds of Ants, Ants of North America Page". On each individual MEM species page, a link is provided (at the bottom of the page) for that species on both the AntWeb site and the Discover Life ant site. Additionally, many of the species found in this list can be identified using the identification keys found on this web site.
