A simple and natural way to get rid of an
Mix soap and water
Mix well 1-2 teaspoons of liquid dish soap with 2l of warm water. Identify the nest and pour the mixture slowly into it. The mixture will kill the ants and prevent them from escaping the nest.
Mix water and White Vinegar in a misting bottle in equal proportions. Spread the solution around the vulnerable areas to an ant infestation. If you want to make the solution more concentrated, forgo the water and spread only the White Vinegar across the affected areas.
White vinegar, available at all grocery stores, is a cheap and effective way to kill and repel ants. It is also a natural cleaning agent. Try using a 1-to-1 vinegar/water mixture to clean hard surfaces, including floors and countertops, wherever ants are likely to travel.
On the other hand, plain table salt does not. It is only effective in intercepting the ants. This should not be applied on heavy ant-infestation.
Just spraying ants with a typical ant spray, will only kill a few, at best, and scatter the colony, making it more difficult to eliminate and thereby prolongs the process. Baiting is the only option that truly gets to the nest and roots out the entire colony.
Cinnamon is a great option for killing ants. When an ant inhales cinnamon, it suffocates and dies. You can use ground cinnamon and sprinkle on the ants' path or around an anthill opening. Cinnamon essential oil also works well to repel ants.
Try combining three parts powdered sugar with one part boric acid. The sugar will lure the ants in and the boric acid will kill them, Pereira says. Liquid is better—adult ants prefer to drink their food—so water this stuff down a little. “I recommend this to a lot of people,” Pereira says.
Simply boil a kettle of water, locate the ant hill and pour it right over the top. The water will gradually trickle through the entire maze of tunnels and flood the colony; the heat of the water will be enough to eliminate any ants that come into contact with it.
Using Salt to Kill Ants
Ants despise salt, and if they come into contact with it, it will kill them because it dehydrates the ants to the point where they drink so much water that they explode. If you can't discover the colony, leave a salt path along the cracks in your driveway to keep them from leaving.
Natural deterrents.
Salt, baby powder, lemon juice, chalk, vinegar, bay leaves, cinnamon, or peppermint oil are a few items that you have around your home that will stop ants from coming inside. Lay these out in areas where you see ants, and they'll stop using that area as an entrance into your house.
Epsom salt can be a very effective pesticide, and it can be used against ants specifically. However, it does pose a risk to your garden if you use too much. Consider saving the Epsom salts for a relaxing bath and pick another organic pesticide if you have a small infestation.
Aside from garnishing your tea, lemons can also be extremely helpful when it comes to combating ants in your home. The smell of the lemons masks the scent trails that they use to get to and from food, and also generally deters them from taking up residence.
Step 3: Spray Entry Points
Use this white vinegar solution to spray all entry points of your home, try to spry all windows, doors, baseboards and the common paths that ants would travel within your home. Give about an hour for this solution to take effect, then after a few hours the ants should be dead.
Many types of ants are drawn to jelly, syrup, honey, candy, and other rich sources of sugar. Many households have areas within their pantry or on their countertops where products such as these get spilled, leaving a tempting source of food for ants to find.
Borax, a mineral used in many cleaning products, is lethal to ants, interfering with their digestive system. Create a syrupy paste with borax, confectioner's sugar and water. Put the mixture inside shallow containers with narrow, ant-sized openings and place them near ant mounds or wherever you see ants.
Repel ants
Leave coffee grounds where the ants are and they will carry it home and eat it. This method takes a few weeks to see, but after a while you'll notice a decrease of the ants population.
Soil: Many ant species build nests in soil, which your yard happens to have. Some species prefer soil that is dry and drains well. If you notice mounds of dirt, ants could be nesting in your yard. Yard Debris: Things like grass clippings, tall grass, overgrown shrubs, rocks, and leaf litter can act as shelter for ants.
