What Kills Black Ants Outside

Black ants may seem like an insignificant part of the complex puzzle of life, but in reality, they have an integral role to play in the web of life. Black ants are predators that feed on other insects and help control populations, thereby helping to maintain the ecological balance.

As it turns out, there are a number of things that can kill black ants outside. One of the most common killers of black ants is insecticides. These can be found in over-the-counter products and are effective at killing black ants. However, insecticides can also be harmful to other species, so it is important to use them with caution.

The use of boiling water is an effective and eco-friendly way to eliminate black ants outside. Boiling water can instantly kill black ants and has no long-term negative effects on the environment. Plus, it is easy to use and can be done anytime, anywhere.

Predators are also a large factor when it comes to killing black ants outside. Predators of black ants include birds, reptiles, small animals and even other insects. Birds, in particular, have been found to have a large negative impact on black ants, as they eat both the adult ants and their larvae.

Temperature also plays a role in killing black ants outside. Temperatures that are too high or too low can lead to the death of black ants. Heat waves or cold spells can cause black ants to die from dehydration or from overexertion. Also, excessive exposure to extreme temperatures could cause the black ants to enter a state of hibernation, which can ultimately lead to their death.

A less extreme, but still effective, way to kill black ants outside is to make sure that their nesting areas are kept clean. This means eliminating food sources, such as spilled food and water, that could attract black ants.


Traps are another way to try and rid yourself of black ants. Traps can be found in many home improvement stores and come in different shapes, sizes and types. Each type of trap has its own advantages and disadvantages, so it is important to research the product you are considering before purchasing.

Some traps are baited with sweets and other food sources that attract black ants. These traps can be very effective when it comes to killing ants. However, they can sometimes be difficult to clean and they may attract other pests, as well.

The type of trap most commonly used to effectively kill black ants is the liquid insecticide trap. This type of trap uses a liquid insecticide to kill black ants almost instantly. These traps are easy to use and cost-effective, but they must be used with caution as they can be very dangerous if not handled properly.

Natural Solutions

In addition to insecticides and traps, there are some natural solutions that can help to keep black ants away. Vinegar and citrus-based sprays are two popular solutions that have been found to be effective at repelling black ants. These sprays are not only effective, but they have no long-term negative effects on the environment.

Another natural method for killing black ants is to introduce predatory insects, such as wasps and spiders, into the area. These predators can help to keep black ants away, as they will prey on them. Introducing predatory insects is a great way to keep black ants under control without using any harsh chemicals.

Overall, killing black ants outside can be done in a variety of ways. Insecticides and traps are two of the most common solutions, but natural solutions such as vinegar and introducing predators can also help to keep black ants at bay. It is important to use these methods with caution, as some can be dangerous if not used properly.

DIY Solutions

DIY solutions are a great way to rid yourself of black ants without having to buy expensive products such as insecticides or traps. Some DIY solutions, such as petroleum jelly and sugar water, are specifically designed to repel black ants. Petroleum jelly, when spread on the edge of walls, will create a barrier that will prevent black ants from entering the area.

Another DIY solution is the use of borax-based solutions. These are most often used in the form of granules, which can be sprinkled around the area where black ants are present. Once the granules are spread, the ants will be attracted to them and will eat them, resulting in death within a few minutes. Although this method is effective, it can also be dangerous to other insects and animals, so it should be used with caution.

A less extreme, but still effective, DIY solution is using diluted soapy water. This can be sprayed directly on the black ants or used as a moat around an area to prevent black ants from entering. This solution is also safe to use around children and other animals.


The best way to deal with a black ant infestation is by preventing it in the first place. This can be done by eliminating potential sources of food in the area and sealing any cracks or crevices in walls and foundations. These steps will discourage black ants from entering your home or garden.

Another important step in keeping black ants away is to eliminate any excess moisture, as black ants are attracted to moist conditions. Eliminating any water sources or damp spots will help to keep black ants away from your home or garden.

Finally, it is essential to keep your home or garden clean and tidy. This will help to discourage ants from setting up shop in the area, as they are not attracted to clean and orderly places. Also, regularly vacuuming or sweeping your floors and surfaces can help to remove food and moisture sources that could attract black ants.


In conclusion, there are a variety of ways to kill black ants outside. Ingredients such as insecticides and traps can be used, as well as natural and DIY solutions. The best way to keep black ants away, however, is by preventing an infestation in the first place. Eliminating potential food and moisture sources and keeping the area clean and tidy will help to dissuade black ants from setting up shop in your home or garden.
