Vinegar—whether white vinegar or apple cider vinegar—is a common ingredient in many kitchens. That's probably why many homeowners hope that vinegar or a mixture of apple cider vinegar and dish soap will kill ants. Unfortunately, it doesn't work.

Soap and water
Provided you really saturate those little critters, the soap actually breaks down their exoskeletons, and they die almost immediately.
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.

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.
Fragrant shampoos, soaps, and lotions may also attract ants, so keep bottles sealed and do not leave residue behind. The best way to keep ants out of your bedroom is to keep food and sugary drinks out too. Ants will come looking for it.
If you spray a vinegar solution on ant trails, it may repel ants for 4–48 hours. However, it won't kill ants or repel them permanently. The acids in vinegar destroy the scent trails ants leave as they travel between their nest and a food source.

Dish Soap. The scent trails that ants use to follow each other into your home can be disrupted with nothing more than ordinary dish soap. Fill a spray bottle with water, add 1/4 cup of dish soap, and shake the bottle to dissolve. Spray the mixture liberally near access points like doorways, windows, and other cracks.
“The most effective method for controlling an ant infestation is using ant baits.

The sugar attracts the ants, and the baking soda is what kills them: It reacts with the acid in their digestive system, and they explode. Place the mixture in strategic locations and wait for the baking soda to do its thing.

Ants may also be found in or around floor drains, inside the motor areas of refrigerators and microwaves, behind wall paper, and in cracks and crevices in cabinets and around walls.
Simply sprinkle baking sofa directly on an ant nest, then spray with white vinegar. This will cause an a foam-like reaction to help kill the nest. The acetic acid in the vinegar will treat a wide range of garden and common houseplant pests but it requires contact.
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.
Ants know to avoid pure baking soda, so you can sprinkle it around doorways, window sills, and other entry points to keep them out of your home. You can also sprinkle some in cabinets, under sinks, and in other dark, moist places where ants may find shelter in your home.
