What do I Need to Know About Argentine Ants?

What do Argentine ants look like? How can I identify them? Before getting to identify these pests, you should know little about them and have an oversight of their behaviors.

Argentine ants are a very great nuisance to the homes they inhabit and gardens as well. They are known to occupy concrete walls, timbers, the floor, and even dwell among humans. Outside human dwellings, they can be found under stones and leaves, due to their inability to dig up deeper nests. One funny fact is that you will only find them in a deep nest if it was abandoned by the ants who previously created the nest.

These ants are commonly found in southern California, as they are known to invade homes in search of food and water. Unlike most ants, the Argentine ants will feed on anything called food! especially sweets, and egg yolks (do not have this substance littered in your home except you want an infestation of these dark-colored ants).

They are well adapted to the urbanized areas of the United States which has a mild climate and well-watered gardens. These ants pose a series of threats to native wildlife by upsetting delicate food webs. They are especially known to inspire fear due to their aggressive behaviors and the large size of their colonies which can literally team-up with other colonies (cool right?)

According to research, three supercolonies of Argentine ants found in America, Japan, and Europe were all closely related to each other even though they were from different countries. Below are reasons why scientists proposed these 3 colonies of Argentine ants to come from a single super-colony:

  • They all possess a similarity in the hydrocarbons present on their cuticles.
  • These ants have a similarity in their non-aggressive and grooming behaviors when interacting with each other, compared to when they mix up with ants from other super-colonies.

 

Did You Know?

  • Strength: Just like other ants, the Argentine ants can lift objects 20 times their body weight. A single of this ant can even lift 10 other ants its own body weight.

Imagine how strong you’ll be if you had such strength.

  • Hearing Abilities: Even though these ants are a great nuisance, they lack ears. Then how do they listen to avoid danger? well, these ants listen by feeling vibrations in the ground using their feet.
  • Level of Destruction: Trust me, you wouldn’t want to experience these guys in your home as they can cause a great lot of damage to household properties, as well as outside your homes.

In the world, these ants are ranked as part of the first 100 most dangerous animals on earth.

  • Insecticides: Using insecticides to get rid of these ants is no use, as it will even increase the reproduction rate of the queen and their population in your home.
  • Beneficiaries: Even though most animals are scared of the Argentine ants, including humans, some insects are gaining certain benefits from them. The Aphids, Whiteflies, and scales give out honeydews to this ant in exchange for protection.

This is somewhat weird, but it’s so true!

  • Aggressiveness: These ants are so aggressive to the extent that they are feared by other insects and reptiles. Argentine ants can even destroy a beehive! wait are you for real? yeah, I am! (smiles)
  • Nativity: These ants are native to Argentina, Brazil, Paraguay, and Uruguay.

Argentine ants are very interesting creatures and are incredibly fascinating but would you want these pests in your home? well, let’s find out.

What Do Argentine Ants Eat?

Argentine ants
Argentine Ants Eating

These ants are omnivorous feeders and will feed on a wide range of organic substances. Argentine ants prefer sweet foods and are often found tending aphids or scale insects on plants, in order to get honeydews in return.

The workers in the colony would rather prefer sweet foods such as syrup (even cough syrup), fruit juices, or plant secretions, and gather protein-based foods to take back to the queens and the larvae. Unlike other smaller sized ants, they prefer sweet food more than protein food.

The queens and larvae feed on protein-based foods almost excessively, while the workers eat sugar-based foods.

Just in case you weren’t really following the Argentine ant’s diet, below is a breakdown of what these ants eat:

  • Sugar Syrup
  • Vomit
  • Honeydew
  • Egg Yolk
  • Plant Nectar
  • Fruit Juice
  • Other Insects and dead animals.
  • In fact, they feed on almost everything you can term “food”

 

What Eats Argentine Ants?

Sadly, there is no known predator of these species of ants, as everyone is scared of getting close to them due to their abilities to attack in large numbers.

Some species of reptiles, birds, and even ants are reaching the stages of extinction because of an invasion by these small but mighty ants.

 

What is the Lifecycle of the Argentine ants?

Unlike in most ants, the Argentine ants have more than one winged queen in the colony producing fertile eggs. One very amazing fact about these queens is that they can keep reproducing these fertile eggs for about 10 years after a single mating with a male, cool right? They are different from other ants in the sense that the queens can leave the colony with the workers to go and form a new colony. Budding is what this process is called.

Just like in other ants, they lay eggs, but they have to bear the responsibility of cleaning themselves, feeding themselves, and raising the young growing ants. The development of these eggs ranges for an average period of 74 days as the queen has the ability to lay a minimum of 60 eggs per day. You surely wouldn’t want all this laying in your home, would you?

Did I forget to mention that all workers in the colony are females? We wouldn’t want men taking care of the eggs (they might break it) (smiles). The workers feed and tend for the larvae, and pupae while the queen cares for them when they emerge as young adults. The queen lays her eggs during the summertime to ensure a quick rate of development of these eggs.

  • The eggs develop to the larvae stage after 28 days.
  • The larvae develop to the pupal stage within a period of 10-60 days.
  • The Pupae develop to adults within a time frame of 11-26 days.

 

Where do Argentine Ants Live?

The nest is usually situated close to a food source (could be in your kitchen) and cannot be easily spotted as they may be situated between bricks, boards, rotting wood, refuse piles, stumps, beehives, and bird nests, etc. When establishing a nest, these ants will infest your home in search of food, water, and a suitable spot for nesting.

They will rather prefer to nest in/close to organic mulch.
