1. Appearance and size

These ants can vary in size from 1/16 of an inch to a quarter of an inch. They have a segmented oval shaped body with a shiny dark brown to black shading of color. Argentine ants have six legs and are classified as insects. They are equipped with antennae which assist them in finding their food and for social correspondence. Furthermore, some of them are equipped with wings.

2. Habitat and distribution

Similar to California queen ants, Argentine ants like to build the colonies in damp conditions specifically located near their source of food. The Argentine ant colonies can grow to enormous sizes and have the potential to cover the entire habitats. For example, their colonies can cover your entire backyard or the whole garden.

3. Reproduction and life cycle

The Argentine ant workers are not able to lay eggs, however; they do direct the development of these eggs into females. The reproduction of male Argentine ants depends upon the supply of food for the larvae. The colonies of these ants have many queens. In some cases, Argentine ants have multiple queens per colony, and a single colony of a thousand worker ants which are male Argentine ants has up to 8 Argentine queen ants.

The colonies reproduce and new nest bud off, and it continues until they take over their habitat. In the case of Argentine ants, a single queen with ten worker ants can initiate a new Argentine ant colony. As Argentine ants thrive in the hot and humid environment, a seasonal low in reproduction takes place during the mid of winter season. It primarily depends on the temperature and a damp environment that is available to them.

4. Diet and habits

These ants prefer to eat sweet material and substances as their food. However, they are not very selective when it comes to their diet. They can eat eggs, meat, fats and oils as well. These ants have the tendency to leave their trails of pheromone which allows them not to visit the same place twice in search of food and waste time. In other ant species only the worker ants are designated with the job to find food, however, in the case of Argentine ants, Queen also play her role for finding food for the colonies.

Argentine ant damage

Argentine ants do contaminate the food using their body wastes behind. It is the only significant threat that they pose to the human health. Even with this minimal amount of risk, invasive Argentine ants are rated amongst the worst animal invaders in the world because they are one of the most difficult ants to manage. When these ants travel and enter a habitat, they tend to replace all other smaller sized ants as well as native ants which can be disturbing for the ecosystem.

For instance, some plants do rely on other native ants to disperse their seeds from one place to another. Many other insects like beetles or reptiles like lizards purely depend upon the native ants, and these mega-colony ants displace the native ants which disturb the ecosystem. Therefore, it is ideal to use sweet syrup baits for these critters. These ants are also dangerous because these ants and some sweet secreting pests remain friendly to one another.

1. Direct and indirect damage to crops

Another problem is that these ants benefit from the aphid colonies, as Argentine ants feed on their secretion known as honeydew. The ants protect these aphids from their predators, and the plant parasites cause damage to the crops.

2. Nuisance pest in homes

Because they do not pose any direct threat to human health but do contaminate foods, they are considered to be nuisance pests. They invade households when they are in search of water and food during their peak reproductive season or when rain floods their nests. When they find plenty of places to hide and build their colonies, they start multiplying, and this requires immediate pest control.

3. Economic threats

Argentine ants are considered as economic threats because they tend plant pests and protect them from their natural predators in return for the sweet substance called honeydew from the pests. Moreover, these ants shift the household pests from one place to another with a better climate so that more honeydew can be produced.
