Ants
ANTS: Argentine (Iridomyrmex humilis)
Description:
Biology:
The Argentine Ant is the most persistent and problematic ant in our environment. Argentine Ants are very aggressive and will drive out or even kill other ant species from their territory. They prefer to nest in the damp soil of landscapes, under rocks, ground covers, walkways, and even in a crack of a concrete slab. They also commonly nest in the sheaths of palms and under plastic landscape sheeting.
Along with some other varieties of ants, Argentine Ants display the fascinating habit of “herding” aphids for food. The ants protect and take care of the aphids and in turn, the ants harvest the honeydew secretions from their aphid herd.
Argentine Ants are known for their huge colonies with seemingly endless trails going in and around structures, invading everything in sight in search of food. Their colossal numbers can overwhelm a lunchroom, kitchen, or office space. Ants find their way through even the smallest cracks and crevices and travel up trees, bushes, or even across telephone wires to enter a building.
Did You Know?
According to leading entomologists, these colonies are part of one giant supercolony that spans 560 miles from San Diego to San Francisco. Some scientists believe that the colony may contain nearly one trillion ants!
Impact:
While ants are not typically dangerous to structures, their presence can be extremely disruptive to those working or living in the buildings they invade.
Solutions:
The best way to stop an ant invasion is to catch it early. A regular monthly inspection by a professional is key to eliminating the chance of a massive influx of ants in the summer.
