One of the most successful groups of insects in Shreveport. Social in nature, they live in colonies. Most nest in the ground, but some species prefer wood, and occasionally some will infest homes and structures depending on the species. Some common structural ant species in northwest Louisiana:
Pharaoh Ants - Extremely small cream colored ants that can have numerous colonies in a structure. The use of traditional treatment methods can actually make this pest ant split off into numerous colonies in a structure. One of the hardest pest ants to control. Usually found around sinks, tubs, plants, pet dishes, microwaves, garbage cans, and in hospital rooms.
Fire Ants - Tough to control small to medium sized ant, normally red to reddish brown. Extremely aggressive mound building ant. Normally found outside under stones, along foundation walls, and throughout lawns, but will sometimes be found inside structures. Extremely painful stinger. Can cause air conditioner compressor malfunction due to mound building in the summertime.
Carpenter Ant - A large black or dark colored ant, normally nocturnal. Normally nests outside in tree trunks, wooden fence posts, and landscaping timbers. Will sometimes be found indoors when they establish "satellite" colonies indoors around windowsills, wood trim, attics and wall voids. they can and will climb telephone lines, power lines, and tree branches to enter a structure.
Argentinean Ant - Medium sized dark brown to black ant that can have numerous colonies in a structure. In extreme cases they can form "supercolonies" that can infest whole neighborhoods. Commonly found indoors around sinks, pet dishes, garbage cans, microwaves, and plants.
