Both cayenne and black pepper repel ants. Ants hate cayenne pepper. Black pepper will work just as well too. Locate the source of the ant infestation problem, sprinkle some pepper around that area and if possible, create a wall that will stop the ants from accessing your household.
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.
Ants hate the smell of strong citrus fruits. Save your orange, lemon and grapefruit peels and scatter them around entry points. It's a natural way to deter ants without harming them.

Diatomaceous Earth is one of the most effective ant-killers out there, and placing them in the ant entryways can solve the problem of “how to get rid of ants permanently”. Diatomaceous Earth is made from remains of diatoms. Basically, by sprinkling them, ants dry and die.
Boiling water is an easy, effective way to kill ants immediately. If you see ants emerging from a crack in the concrete or a hole in the ground, pour boiling water into the area. This will kill many of the ants within it.
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.
Ants prefer salty snacks to sugary ones, at least in inland areas that tend to be salt-poor, according to a new study published this week in the journal Proceedings of the National Academy of Sciences.
Better Than Hopscotch: Ants will not cross a chalk line. Draw a chalk line in front of exterior doors, to prevent ants from coming into the house. You can also draw a chalk line around tables on the porch or patio, to keep pesky ants away while dining outdoors.
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.
Ants hate Vinegar. The smell of Vinegar will cause them to stay away from it or permanently leave the house. Ants crawl in a straight line, marching towards the food sources. The Vinegar solution will interfere with these pheromones, and the ants will get lost.
These are chemicals that send signals to other ants. Pheromones send messages of a food source, sexual desire, and death. It is advised not to squash ants, doing so will only release pheromones and trigger more ants to come to the location and cause more trouble to you and your family.

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.
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.

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.
Ants seem to be attracted to the electronic components of your AC unit, and often become stuck in between electrical contact points on the unit. When the ants burrow themselves in these tiny spaces and touch the contacts, it can cause malfunction and even permanent damage to the unit if the pests are never removed.
As a general rule, ants are strongly attracted to smells from candy, sweet-scented foods, carbohydrates, sugary drinks, fruit-scented candles, meat, perfume, nuts, seeds, grease, oil fats, and dirty laundry.

Diatomaceous earth (DE) is not only inexpensive and effective; it's non-toxic to kids, birds, and pets. And yet it destroys ants, earwigs, slugs, beetles, ticks, fleas, cockroaches, and bed bugs. As these pasts move across the powder, it sticks to their feet and legs only to get into their joints and exoskeleton.
