Tawny crazy ants are known for building colonies in odd places like pipes, car engines and computers, and for sometimes short-circuiting electronics. They are more likely to alarm you by invading places you don’t normally expect to find ants. Although their bite is mild, an encounter can be unnerving because they tend to swarm in chaotic fashion. Tawny crazy ants do not have stingers, but they can bite. They can cause damage to wood structures in the process of creating galleries they use for nesting. While carpenter ants don’t eat wood, they nest in it. For example, carpenter ants are probably more interested in the food you have spilled or left behind. Unless they are the fire ants mentioned above, red ants are generally more annoying or destructive than they are dangerous. Though the sting of a velvet ant can be painful, these “ants” are not known to be aggressive. Some species have red bands, and the female velvet ant lacks wings, so their appearance can be similar to red ants. Velvet ants are actually members of the wasp family.Researchers at the University of Texas at Austin discovered that tawny crazy ants have begun wiping out RIFA colonies and taking over their territory. Tawny crazy ants are a relatively new species in North America, but they are fast gaining dominance in the areas where they are currently found.Along with other ant species, carpenter ant swarmers are also sometimes mistaken for termites, due to their appearance and the fact they do build colonies in wooden structures and trees. They are often found on trees and plants or near easy food sources indoors, such as pet bowls or sugary spills. Most fire ants only grow to be as large as a quarter of an inch. Carpenter ants can grow to five-eighths of an inch in size.Other species of red ants can be mistaken for fire ants due to their reddish-brown appearance and a few similar characteristics. The Southern red fire ant is most commonly encountered in arid regions of Texas, New Mexico, Arizona and California. The red version prefers a desert-like climate, and its mounds are smaller and looser in form than other varieties. Southern fire ants - also known as desert or California fire ants - are found across the American South, as well.Unlike many ant species, tropical fire ants live in the soil and are most commonly found in dry, coastal areas of Hawaii and the southern United States. The heads of tropical fire ants are larger and more square-shaped, however. Tropical fire ants also invaded new territories via shipping routes and are almost identical to the RIFA variety.Since their introduction this invasive species has infested land in 15 southeastern states. Legend has it, they traveled here in the ships' ballast tanks where soil was used for stabilization. They are believed to have entered the country from South America via the port of Mobile, Alabama, in the 1930s. Red Imported Fire Ants (RIFA) are the most common red ants in the United States.True fire ants sport a red or reddish-brown appearance and belong to the genus Solenopsis. Not all red ant species are fire ants, and not all fire ants are red in color. Here are a few basic facts about fire ants, as well as some big red ants you may encounter. Learning more about the different species of big red ants common to your area can make it easier to identify the ones you are seeing.
