How To Get Rid Of Black Ants | A Review of Scientifically Proven Methods

1. The first step to take is to figure out where they come from and where their nests are located. As the University of California experts recommend,, regularly inspecting your home for ants or their entry points. Monitor for ants near attractive food sources or moist areas.

{code 416}

2. Your main aim is to kill the queen.

The University of Kentucky specialists warn that the mistake most people make when attempting to control ants is only spraying the ants they see. This approach usually fails because the ants seen foraging over exposed surfaces are only a small portion of the colony.

Typically, there will be thousands of additional ants including one or more egg-laying queens hidden somewhere in a nest. Eliminating queens and other colony members within nests is often the key to effective ant control. Our review of TOP 12 black ant killers will help you decide on which product you should purchase.

3. The only way to achieve your goal and kill the queen is to feed it poison.

There are a great number of various slow-acting baits, and such poison acts like domino. A poisoned insect has enough time to share a poisoned piece of food with others and their queen before dying. Not only does this worker carry some food into the colony, it also attracts others to the bait. If used properly, baits and poisoned bait stations are much safer than sprays.

TERRO Liquid Ant Baits: photo

Baits are the key method of getting rid of black ants.

Scientists believe that baits in dispensers or containers are more effective than disposable ones, especially liquid ones that tend to dry quickly. Read more: TOP 12 black ant killers.

Gel baits are used when you need to leave a small amount of bait somewhere inaccessible: in the cracks, behind the skirting boards or on pipes and wiring.

Ants tastes’ differ and they are extremely finicky. While most ants love anything sugary, they are opportunistic eaters. That is why you will have to provide a variety of poison baits for insects or switch sugar and protein-based baits frequently. First, attract them to a non-toxic food source like sugar milk, cherry or diced crickets or mealworms. After they start feeding, replace the nontoxic food source with several different toxic baits, and let them choose the one they prefer.

I Have a Black Ant in My Kitchen, Should I Be Worried?

Have you noticed a single ant at home and can’t find any others? Should you be worried? You should. As the scientists explain, this isn’t a wandering ant, but a forager looking for some food for the colony. Once it finds some, it signals the others to attract them to the food source. At this stage, you can stop the invasion by eliminating the forager. If you don’t do this, soon enough, hundreds or thousands of insects will head to your food stocks along the newly formed trails.

What Should You Do If There Are Nests in the Wall?

As the Texas A&M University entomologists recommend, nests in wall voids can be treated by injecting aerosol through cracks and crevices and around baseboards. If nests cannot be located, toxic baits can be effective when placed on foraging trails.

Top-12 Black Ant Killers

In accordance with the scientists’ recommendations we have found 12 effective and accessible products: organic for kitchen and food storage, foam for insects in the walls and effective baits for removing the entire colony, including the queen as well as powerful outdoor insecticides.

How to Kill Black Ants in the House & Kitchen

1. TERRO T300B Liquid Ant Bait Ant Killer | Best Indoor Slow-Acting Poison

TERRO T300B Liquid Ant Baits: photo

A slow-acting Borax is the most popular and affordable option, which is why I recommend you try this product. This insecticide targets foraging ants but kills them slowly, within 2-3 days, so that they could share the poison with other members of the colony. The active ingredient is Borax that works by interfering with the insect’s digestive system and killing them after a while.

The baits come in a snap-off tab, which makes the product easy-to-use. Place the item on a flat surface, with the best locations including the spots along baseboards, under electric equipment, and around the windows. Do not place the station in the areas that have been previously sprayed with insecticide, nor should you leave any food available in the room.

The manufacturer promises that the ants will be eliminated in about two weeks but suggests that you should place new stations every three months to prevent new colonies from establishing. Based on the feedback, customers are happy with this product, rating it highly. According to them, at first, you will see a line of ants coming to the trap and a line returning to the nest. But don’t give in to the temptation to kill them! Within a month, there will be not an ant to be seen.

What I do not like about this solution is that it is liquid and, therefore, dries out quicker than a gel.

{code 1001}

2. Syngenta Advion Ant Gel 4 tubes 30 grams each

Dupont Advion Ant Gel Bait, 4 Tubes with Plunger: photo

If you need a faster result, opt for Advion gel baits that can be used either with a station or without it. Applying the gel directly on the surface is a more effective but less safe solution, especially if you own pets.

With the active ingredient of Indoxacarb (0.05%), this baits is intended to kill the entire colony. According to a study conducted by researchers at the University of Arizona, Indoxacarb resulted in high levels of ant mortality up to three months after application.

You can place the bait in hard-to-reach confined spaces, such as cracks and crevices, where a station will not fit. The recommended application areas also include the spots beneath electric appliances and furniture, and around the sink.

This product is as popular as the previous one, with customers reporting a noticeable decrease in ants.

Although this product is quite expensive, the users unanimously agree that it is very effective and much cheaper than hiring exterminators.

This is special outdoor bait. A borax-based bait station is installed on a surface. This slow-acting bait acts simply: foragers will find the bait and share it with other colony members.

AMDRO Ant Block Granules: photo

Your protection line against ants should start outside the house, which is why I recommend purchasing an insecticide that was developed specifically for barrier treatment.

Scientists from the University of California note that this chemical compound is effective both when it is used alone and in combination with other active ingredients.

The solution will kill the entire colony and its queen, with a residue lasting up to three months. This 24-ounce canister will cover an area of more than 1,000 linear feet, all you need to do is distribute the bait around the perimeter of your home. It is labeled for more than 20 most widespread species of ants, so you will not have to bother your head over whether you have identified the species correctly. Nor will you have to search for their nest or detect their trails. Creating a barrier is an all-in-one approach and a good way to eliminate even those ants that you cannot see.

How to Get Rid of Black Ants Naturally | Natural Treatment: Diatomaceous Earth, Boric Acid and Essential Oils

The University of Clemson scientists University of Clemson scientists distinguish limonene as one of the vegetative products effective against ants: limonene is produced from citrus oils extracted from oranges and other citrus fruit peels. It is used as a contact insecticide against ants, roaches, palmetto bugs, fleas, silverfish and many other insects.

Diatomaceous Earth is the most famous organic means of getting rid of insect pests. This mineral substance, which contains fossil remains of diatom algae, is crushed into powder sharp enough to cut through the chitinous cover of an insect and cause deadly damage to its insides. Diatomaceous Earth is safe for humans and animals, since it cannot penetrate their elastic skin.

10. Safer 51703 Diatomaceous Earth

The above mentioned diatomaceous earth is the most popular non-toxic insecticide. It is safe for humans and pets but not for insects. The fossil remains of diatom algae are crushed to a state of sharp deadly powder that can cut through the chitinous cover of an insect and cause deadly dehydration. Such a contact killer is unlikely to reach the queen so the colony will regenerate soon enough and repeat treatment will be required.

Safer Brand 51703 Diatomaceous Earth: photo

Safer Brand manufactures diatomaceous earth in 4-pound packs. Sprinkle the places of congestion and possible migration of ants in the house with it. It is undesirable to use diatomaceous earth outdoors as it is not water-proof. It is also effective against bed bugs, fleas, centipedes and other pests.

Black Ant Repellent

Eugenol, an active ingredient of clove oil, is actively used in organic insecticides. It is used when getting rid of ants, cockroaches, mites, flies, wasps, spiders and other arthropods, including herbivorous pests. Eugenol acts quickly but is not considered eco-friendly. It irritates human skin and eye mucous membranes, and that is why wearing safety goggles and rubber gloves is recommended. It is often combined with thyme, sesame, rosemary and other essential oils.

12. Majestic Pure Clove Essential Oil- Pure and Natural

Clove Essential Oil: photo

Clove essential oil is not an insecticide; it is used for contact insect repelling as it contains eugenol approved by scientists for eliminating pests. Mix some water with the essential oil in a ten to one ratio and use it to create a protective barrier around your house. Caution! Essential oils are dangerous for pets, especially cats, for pregnant women and small children. Don’t use pure essential oils and don’t be too hopeful if you suffer from a large-scale infestation. In this case, go back to using baits.

Know Your Enemy: Types of Black Ants

Ants while easily recognizable, become unwelcome visitors when they find a food source in your home and bring back others from the colony. Once in your house, they damage furniture and climb into food storage areas. Outdoors, they can become a nuisance in your garden, can spoil your outdoor retreat and even bite you unpleasantly. Let us examine these species in details. Here are the black ants.

The black garden ant (Lasius niger), also known as the common black ant, is a real headache for gardeners. They nest in grassy areas and eat ripe fruits, especially fruits like strawberries. Black or dark brown workers are about 3-5 mm (⅛-3/16 of an inch) long. Lasius niger queens are extremely tenacious, their average life expectancy is 15 years and some even survive for up to 30 years. Compare this with fire ant queens who live for 3 years on average. Black garden ants build their nests in the soil and under various objects, such as stones, wood, construction materials debris, as well as in hollows and inside some rotten wood. They feed on small insects and other invertebrates, aphids’ secretions and other sweets. They breed aphids on fruit trees and garden plants to consume the aphids sweet secretions. In early summer, they usually explore new areas in search of new food sources. They can make their way through the brickwork and cement and find or create new trails there. It is this species that people use for observation, creating artificial lab ant farms.

black garden ant

Odorous house ant. They are small black ants ⅛ of an inch long. Their color varies from dark brown to shiny black. They have an uneven chest and exude a strong smell if crushed. They feed on insects, aphids’ secretion and sweet foods. They lay their trails along tree branches, house foundations and skirting boards, along the wiring and pipes and carpet edges. Outside, they tend to live in colonies in the soil under stones, fallen trees or garbage, and in apartments, they build nests in house walls, around water pipes and heating pipes. Their colonies are usually large and can number up to 10 thousand insects with many queens. If they have occupied the walls, the entomologists recommend spraying insecticides in the cracks. If you do not know the exact location of their nest, use poisonous baits.

Pavement ant. Workers are dark brown or black, all of them are 3/16 of an inch long. They feed on sweets and insects and can also get in food rich in fats. They won’t spurn pet food and prefer to go “grocery shopping” at night. Their mounds are located in turf, under stones, wood or paving tiles and small anthills can be found near water sources. A colony has one queen, different colonies are at war.

Crazy ants. These are black shiny ants 1/16 of an inch long. As the University of Florida, scientists explain,, that their common name arises from its characteristic, erratic and rapid movement, and habit of not following trails as often as other ants. Their antennae and limbs are much longer than other species. They hunt insects or gather the secretions of aphids and scale insects. In the United States, they have widespread population from Florida to South Carolina and west to Texas; it can also be encountered in other states.

Little black ants. They are tiny, from 1/32 to 1/16 of an inch in length. Their presence can be detected by small craters in the ground. They often forage long distances from their nests, so their nests are often difficult to control. They live near trees or stone buildings and sometimes penetrate houses. Their preferences in food are unpretentious. They are widely distributed throughout southeastern Canada as well as northern and eastern sections of the United States, southward to the Pacific Coast. They are common in the southern half of California and in the San Francisco Bay area.

little black ants

Carpenter ant — Camponotus spp. Adult workers reach ¼-½ of an inch in length and are black or black and red. If you disturb them, they will exude a typical odor. They feed on insects, aphids’ secretion, fruit nectar and other sweets. They are nasty indeed as they gnaw maze trails and galleries in dry wood where their colony settles. Initially, their presence goes unnoticed. If you happen to face this very species, read our guide, “How to get rid of carpenter ants”.
