The dreaded Argentine ant…(Part 2)

The Argentine ant is one invasive ant that is on the move and whose advancements should be closely monitored. Here is part 2 in our Argentine ant series, and a look the pest control procedures that are taken by Meryl’s Termite and Pest Control.

The Argentine ant is black or darkish brown in color. It’s native to such place as Argentina (thus where it gets it’s name), Brazil, Uruguay, and Paraguay. It is now an introduced species, or invasive species and has been accidentally introduced to such places with Mediterranean type climates including Japan , New Zealand, Africa, Australia as well as other places like the United States. The Argentine ant was first identified in Argentina in 1866. Other similar species that can sometimes be confused with the Argentine ant is the related Pharaoh Ant.

The worker ants are are smaller than the queens and can fit into very small holes that they can find in order to enter a structure or home. in my own experience with these ants they have their main nesting colony in trees, both alive or dead, although they will also nest in the ground, wall voids, and cracks in concrete walls. In areas such as forests they will nest in loose leaf litter, small stones, or fallen over logs. They usually are unable to dig very deep but if another ant colony is already established and abandoned by another ant species, the Argentine ant will take over their nest.

The Argentine ant is a very hardy ant adapting well to it’s environment. They spread quickly and remind me of a similar situation with the red imported fire ant. They will however, by limited to warmer climates as they don’t tolerate lower temperatures in the north. The ants rank as one of the worst invasive species, and most destructive to our environment and ecosystem.

As far as pest control goes, they can be treated somewhat similar to that of carpenter ants. During ho and dry weather is usually when they will enter a home or similar structure looking for food or water. Spray should be limited to a non-repellent pesticide because a repellent my cause the queen to lay more eggs which can compound the problem. Industry standard baiting and ant traps are the preferred method of pest control, while tracking the ants to their nest will greatly affect total success of eradication of the colony. We at Meryl’s Termite and Pest Control would discourage the use of over the counter pesticides when dealing with such a menace. In Florida several of our ant and cockroach species are treated with different methods depending on the species. One must have a knowledge of the ant they are dealing with, it’s biology, habits and life-cycle if one is to achieve successful control.
