How to Get Rid of Black Ants

Exterminate the black ant infestation in your home.

The moment most people notice a black ant in their kitchen, “Ride of the Valkyries” begins playing in their heads. With a few swift movements, they begin dispatching the tiny invaders one by one. This strategy is about as effective as trying to clean the dust off your shelves by removing each individual speck. Even though it’s a natural reaction, allow us to share some better strategies. Here’s how you get rid of black ants in your home.


How to get rid of black ants


Australian black ants can be particularly annoying. With the average number of workers around 4-7 thousand and a queen that can live up to 30 years, you can have a severe infestation on your hands. Don’t worry, here’s what you can do in order to deal with it:

Identify the source of the infestation.

Ants don’t spontaneously show up into your home because they have nothing better to do. If you find ants in your kitchen, they’re there in order to facilitate the survival of their colony. They’re foraging for food or looking for water. Because they use chemicals as a way to mark their pathways, you can easily detect where they come from. It’s usually the last place you’d figure, like under the kitchen sink or other moist spaces. Under the door is also among the usual suspects. Whatever the source is, find it and try to seal it.

Clean the house thoroughly.

Sometimes, no matter how hard you try, you can’t keep your place spotless. This is usually the time pests appear to remind you why you should. Make sure you clean the entire house top to bottom thoroughly (or hire a cleaner if you don’t feel like it or don’t have the time). This is one way to discourage future black ant visits (for a while). The thorough cleaning usually dissipates their chemical trails which makes it harder for them to get back to your house (think “Hansel and Gretel”, but if there were literally thousands of them you weren’t planning to eat them).

Spray white vinegar along the trail.

The idea is white vinegar will act as a deterrent. It’s useful in some cases, not so much in other. You can still give it a try. Especially if you find where the ants are coming in.

Use cinnamon at the entry points.

Cinnamon is a natural deterrent that helps with some species. It’s not a guarantee, but it’s another harmless method you can try before you get to the heavy stuff.

DIY black ant extermination methods

In case you’re the kind of person who wants to do everything on their own, here are some DIY black ant extermination methods:

Sugar and borax.

This is a deadly combination. The sugar attracts the ants and the borax deals with them. Permanently (at least the ones that come into contact with it). If you’re lucky, they might even bring some to the nest and do even more damage to the colony. Note: if you have pets or kids, mix this with a bit of water. Use pieces of cotton to absorb some of the mixture and place around the path of the black ants. If you’re really lucky, they will bring the cotton to their nests.

Use baits or slow acting poisons.

You’ve tried the steps above but they’ve just delayed the inevitable. Fear not – the game isn’t over, yet. The battle has just begun. The next step is to use a “Trojan horse”. Devious, yes, but also quite effective. Use a bait they will bring to the nest, which will poison the queen. Thing is, the queen is the most essential part of the colony. Without her, there is no colony. Even if you kill every single ant you encounter, more will come. But if you manage to kill the queen (or have the other ants inadvertently kill the queen), then the colony is finished and they will leave you alone.

Use natural solutions if you want to avoid pesticides.

If you have a reason to avoid chemicals, there are also natural remedies you can try. One of them is boric acid. The other is diatomaceous earth freely sprinkled where ants my pass by.

Appearance of the black ant


Appearance of the black ants

  • Queens are mid brown, while workers are dark brown to black in colour.
  • Workers black ants are around three to five millimetres in length.
  • Queen black ants can grow up to 15mm in size.
Queen black ants are characterized by their two pair of wings, which she removes once they mate. The wings are also used as nutrition over the winter months.


Behaviour of black ants


Black ants have a traditional social structure. There are three distinct castes:

Queen

The queen is the only fertile female ant. Contrary to popular belief, she has very little power over the happenings of the colony. She doesn’t “control” other ants. The queen’s only function is to reproduce. That’s her importance for the colony and why the other ants take such good care of her. Outside of that, she has very little function. The queens can live up to 30 years.

Drones

The drones are male ants whose only function is to mate with the queen, after which they die. They are winged ants and have a very short lifespan.

Workers

The workers are responsible for pretty much everything else. They are the ones that maintain the nest, find food, bring it to the nest, guard the nest, expand the nest and whatever else you can think of.

This is the reason the queen is so important. With her dead, the colony has no future.


Damages black ants can cause to buildings


Black ants can cause structural damage. Their digging habits can cause shifts in the sands/turf under the house. Needless to say, this is not the best thing that can happen under your home.

Aside from that, they can damage wooden foundations if it turns out you’re dealing with carpenter ants. Unlike termites, they don’t eat the wood, but dig inside of it and make their colonies there. This can be just as dangerous as the damage caused by termites, though. Immediate actions need to be undertaken. If you’re not sure what to do, you can always opt for professional ant control.
