The stated remedies above are only a part of the possible solutions you can use in dealing with black ants.

What Are Little Black Ants?

Little black ants are social insects that live in large colonies. They’re most prevalent in rotting logs and can also be found under rocks and piles of lumber or bricks.

Once they enter your home, they’ll nest in places like wall voids, behind facades, woodwork, and decaying wood or masonry. Little back ants are about 1/16 of an inch and are typically jet-black in color. 

They live in large colonies, comprising 2,000 workers and several queens. Additionally, they scavenge for food in trails and are typically attracted to sweets, greases, and meats. They’re usually seen scavenging for food in long trails on the sidewalk of your property or kitchen cabinets. 

How Do You Identify Little Black Ants?

You can recognize black ants with their dark brown or jet-black color. They are about 1/16 of an inch in length and have a round, asymmetrical shape.

These minuscule insects have uneven, round thorax and antennae that are divided into twelve segments. In addition, they possess two nodes on the petiole. They’re also pretty small and have a shiny appearance, compared to other ant species that are dull.

Where Can You Find Little Black Ants

You can usually find them in dark and hidden spots. Outdoors, you may see the worker ants forage in trails, typically along the foundation walls or sidewalks. 

Indoors they can be found in wooden items, walls, and the junction between the walls and carpet.

How Did These Little Black Ants Get Into Your Home?

It’s also best to repair the cracks and holes in your place to ensure they have a lesser point of entry. When you notice some ants in your house, it’s best to scan your property ahead for infestation. This may have come from outdoors or could be indoors.

Thus, take time to inspect your place to avoid severe infestation on your property.

What Damage Do Little Black Ants Cause?

What Damage Do Little Black Ants Cause

In general, little black ants don’t cause severe damage to your property. However, they can create jagged patches and holes in the turf by moving the soil beneath.

To get rid of these black ants, you may opt for natural ways or chemical methods. You may also call for a local pest control expert to inspect your place and solve the ant problem for you.

If you want to treat the black ants yourself, you may consider the following methods:

Use Chemical Products

For chemical methods, many available products in the market kill ants effectively. But, you have to choose the one that wouldn’t harm your kids or pets

The Use of Natural Means

One of the best ways to get rid of ants is the use of borax . Borax has a component that acts as a poison when ingested. This damages the digestive system of ants, killing them in the process.

Just mix borax with sweet things, such as syrup and sugar, and you’ll have your effective bait. In addition, coffee grounds, boiling water, and cornstarch are also great options for getting rid of your black ants’ dilemma.

Moreover, you may also opt for herbs and spices, essential oils, vinegar, and chalk. These are great items for deterring ants from invading your space.

So, whenever you face these ant types, you may use these natural means to eliminate them. To know further about natural means, you may continue reading the given remedies below.

How to Get Rid of Little Black Ants Naturally?

When consumed, borax  acts as a slow-acting poison, damaging the digestive systems of ants. This is then passed to a larger ant population, resulting in the death of many ants.

Just mix equal parts of borax and sugar or syrup and put the mix where ants can easily find it. However, make sure that your children or pets won’t reach it, as this can still be toxic.

Diatomaceous Earth (DE)

Diatomaceous Earth  is another way of getting rid of black ants. This is composed of diatoms—the aquatic organisms’ fossilized remains.

This works by sprinkling DE on ants, which absorbs the oils in their exoskeleton, drying them out. Its component is an irritant to avoid breathing it or letting it contact your skin.

Peppermint Oil 

Peppermint oil  is one of the best oils you can use to discourage ants from invading your place. Just fill the mixing bowl with 2 cups of water and blend in at least 10 to 20 drops of peppermint oil.

Spray the mixture around your windows and baseboards and let it dry. Ensure that your pets aren’t exposed to this solution as they can get sick of it, particularly cats.

Boiling Water

This is one of the most straightforward methods of killing ants. Just boil some water and pour it directly into the holes near your home where ants are nesting. 

This method is effective in killing many ants, but this wouldn’t wipe out the entire colony. Thus, make sure to pour hot water into every ant’s hole you see. 

Cinnamon Leaf Essential Oil

Another option you have is cinnamon leaf essential oil . This oil contains compounds such as trans-cinnamaldehyde that are proven effective in repelling ants

To apply this, soak cotton balls with cinnamon leaf essential oil and place them where ants can easily find them.

Boric Acid

Boric acid  is proven effective in killing worker ants and their queens after three weeks of exposure. This erodes their stomachs and outer shells, which kill them in the process.

However, you must take extra precautions in using this product as this is a type of poison. Make sure that pets and children won’t have access to the treated area to ensure their safety.

Furthermore, you have to wear gloves while executing the treatment. To make the solution:

Step 1: Prepare 1 cup of warm water, 1/2 teaspoon of boric acid, and 8 teaspoons of sugar. Then, mix them all together.

Step 2: Stir until the boric acid and sugar are dissolved completely.

Step 3: Once done, soak cotton balls with the solution and put them on the grounds of your home, where ants are frequent.

Boric acid can also be used as a DIY ant trap by mixing the powder with corn syrup or other sweets that attracts ants. Place the bait in the cardboard and put it in areas where ants are typically seen.

With the use of cornstarch , you can choke the ants. Just apply a liberal amount of cornstarch directly on the black ants and add some water on the top.

This will suffocate and drown the ants, leading to their demise.
