Black Ants In Garden

In the case of a garden infestation, your main concern is locating the point of entry into your home.

There will be a small gap somewhere for the army of ants to get through. Typically this small gap is the passageway that leads the ants to a food source indoors.

Black Ants In House

An internal infestation is more problematic to find and to control. Generally, the ants have decided your home provides better shelter than a pile of logs or the underside of a rock. Usually, they will hold up inside the external wall cavity or some other similar space where it is warm, dark, and sheltered.

They will find the smallest gap in your external brickwork or around doors and windows and move through it in search of food or shelter.

4 Simple Steps To Remove Little Black Ants

Locating the ant colony is an essential task to get rid of ants completely. The ants you see running around your kitchen floor are the worker ants, searching out food.

Eliminating these will help, but it won’t completely eradicate your problem. The colony will simply send out more ants to replace the soldiers missing in action.

You need to find the entry point into your home and block it, or locate the nest within your home and destroy it.

1. Find The Ant Trail

Finding the ant trail will lead you to their entry point, their nest or a food source.

The ant trail is a pheromone pathway that the ants follow. It’s not the line of actual ants, as you may think, it’s a smell they are hardwired to follow. This means the ant trail is actually invisible to the human eye. More often than not, you will only find the trail if the ants are using it, giving away its presence.

Once you notice the ants marching in a line, follow it. This will lead you to the ant entry point, the nest, or lead you to the reason they invaded your home…food.

Tip

If you cannot find the ant trail then place a dab of honey or jam on a piece of card and lay it on the floor where you have seen ant activity. Wait a couple of hours for the worker ants to give away their trail. Follow the trail and find the ants’ entry point or nest.

Establish if the ants are coming into your house to the bait, or from an infestation inside your home.

2. Remove the Ant Food Source

If the Little Black Ants give-away the food source it is essential to clean thoroughly. Remove any trace of food residue with a detergent. Seal any loosely packed foods in airtight jars.

3. Block The Entry Point

Next, you need to block the entry point into your home. You may remember me asking you to explore both ends of the trail. The food source and entry point.

Use a domestic decorators filler, expanding foam or mastic gun to block the entry point to prevent any future invasion.

4. Treat The Ant Nest or Colony

If you find the infestation is inside your home or an outbuilding, you will want to treat the nest to permanently fix your problem. There are several ways to do this, but for an internal ant problem, traps, baits, and insecticide powders work best. So let’s look at these options in more detail.

Choosing Home Remedy ‘Ant Killer’ Products

Black Ant Powder

Using Black Ant powder is an effective way to treat ant colonies. Just sprinkle the dust across the known ant pathways and into the opening of the nest.

The dust particles from the powder are picked up by the ants on contact. The powder will be effective within 30-60 minutes. Killing the little black ants.

The presence of ant powder in the nest will also prevent re-infestations for about 12 weeks. If needed, re-apply the powder until the colony is completely eliminated.

Black Ant Bait Traps

Ant traps contain killing chemicals mixed with feed stimulant materials to attract worker ants. Workers carry small portions of the ant trap (which has the killing chemical) to the nest to feed other workers ants, larvae, and queens. Using this method, you can successfully kill the entire colony.

Baiting is one of the most effective ways to treat the ant colony both indoors and outdoors. Place them on the ant trails you have located. Put them near the entry point or in other areas of ant activity.

Each manufacturer may use different kinds of ant bait inside their traps, some use sweet-flavored bait or maybe a protein-based ingredient. All of which are effective.

Be patient! It can take several days or even weeks to eliminate the entire ant nest. Just keep reapplying until the bait traps until all signs of ant life are gone.

Tip

When using an ant bait, be sure you remove all other food sources such as dirty dishes, crumbs on the floor, or pet food. This is to ensure that the bait is the only food available to the ants.

Professional Ant Exterminators

Depending on the danger posed by the ant species, or the size of the infestation, you have to choose between the do-it-yourself products or calling a professional.

Given Little Black Ants pose no risk to humans, we suggest you roll your sleeves up and tackle the critters directly.  

If you can’t stomach it, you can expect to pay between $150-$300 per home visit from an pest control professional.

When Should You Call An Ant Exterminator?

If ants continue to make their way into your home, even after multiple DIY treatments, it means that something else is in play. In this case, calling a licensed pest control professional is the best option to effectively treat and seek advice on how to prevent future infestations. 

When the ants can sting, its better to be safe than sorry.

Even though little black ants have a stinger, they’re not dangerous. But if you notice severe or strange reactions, it is most likely another species. Seek medical attention immediately.

In this case call a pest control professional to locate and remove the ant colony.

How To Prevent Ant Infestations

The best way to avoid infestations is not attracting them into your house in the first place. Most species of ants are simply in search of food. You can’t blame them for wanting to munch on the candy you left on the table, or the sugary crumbs lying on your floor.

Here are a few actionable steps that will help you prevent ant infestations:

Practice Good Sanitation

Sanitation is key to a pest-free environment. Like all living creatures, ants need food to survive. If there are no leftovers in your home that the ants can access, they will not stay for long.

Keep the floors swept, and the kitchen workbench cleaned. Sweep and vacuum regularly. Sometimes, we won’t notice the food crumbs on the floor, or behind the kitchen furniture.

Clean up dirty dishes. It might not be the most fun thing to do right after a scrumptious meal, but dirty dishes invite ants, and you don’t want that, right!

Keep food in sealed containers. It is not likely for ants to crawl into airtight containers, so seal all the food storage containers after use.

Tip

Do not forget to wipe down the outside of the storage bins and waste containers. Ants can nibble on even the smallest morsel of food stuck on a container.

Seal Off Gaps And Cracks

Though ant colonies are usually found outdoors, they can form in the cracks of rotten wood, gaps in the walls, window frames, and cabinets. It is often hard to locate an ant colony, as most of them are hidden in these tiny gaps and cracks.

Seal all the cracks in your home, and the ants will have a hard time setting up a nest. This will prevent ant infestations to an extent.

Remove Ant Trails

When a worker ant finds food, it leaves a trail made of pheromones along their route for the other ants to follow. Removing ant trails will eliminate the scent, which will prevent them from following the same route.

There are many ways to remove ant trails. You can use a mix of vinegar and water or baking soda and water to clean the trail completely. Or a good detergent will do the trick.

But don’t try to remove the trail as soon as you discover it. Remember use it to locate the source of your ant infestation first.

Repair Leaky Pipes And Faucets

Little black ants typically live outdoors in decaying wood and other open areas, but they also build their nests in cracks in walls. A few species of ants prefer to live in moist areas. Look out for leaky pipes and faucets, as these may serve as ideal sites to set up ant colonies.

Summary How To Get Rid Of Little Black Ants

Even when you see thousands of ants rampaging across your kitchen floor there is hope. In truth, it’s not a complicated process to rid your home of the army.

Simply locate the ant trail and work your way back to the entry point or nest. Take appropriate steps to block the entry point to prevent re-infestation. Then apply one of the treatments we have recommended to destroy the colony and queen.
