Ants are an extremely common pest problem. The occasional ant may not pose much threat, but if a large swarm has made its home in your yard or around your house, the resulting invasion can be more than a little problematic. If you need to kill off ants invading your home, you can use natural, household, or ant-specific pesticides.
Steps
-
Sprinkle food-grade diatomaceous earth around problem areas. Apply a fine layer of diatomaceous earth anywhere you notice ants gathering in. Common indoor areas are behind appliances, in cabinets, along the edges of carpets, and beneath rugs. Outdoor areas such as entrance ways, patios, window frames, and garden beds are also common. [1] X Research source
- Only use food-grade diatomaceous earth. Some diatomaceous earth is used for cleaning swimming pools, but this variety usually contains pesticides and other chemicals that can be toxic to pets and small children if ingested. On the other hand, food-grade diatomaceous earth is non-toxic, and is safe to use throughout your home.
- Diatomaceous earth is a natural compound made from ground, fossilized shells of diatoms, a type of small marine organism.
- The powder is very abrasive and absorbent. Once an ant crosses over it, diatomaceous earth damages the waxy, protective coating on the ant's exterior, which means that the ant can't hold water. The ant does not die instantaneously, but it does eventually die from dehydration.
- The ants need to physically come into contact with diatomaceous earth for it to be effective.

Hussam Bin Break of Diagno Pest Control says: "There are a number of different kinds of ants, but they basically behave the same way. They forage for food, and if they find a food source, they're going to keep coming for it. I've even treated ants in a 12th floor apartment."

Spray the ants and entry points with white vinegar and water. Make a solution that is equal parts white vinegar and water. Put it into a spray bottle, and spray all of the entry points to your home, such as windows, doors, and baseboard. You can spray the ants directly too.

- This will take a few hours to kill any ants that cross over these areas.
- Repeat this every day for 1 week for the best results.
- You can wipe up any dead ants with a damp paper towel.

Use a dish soap and water mixture to kill visible ants. Combine equal parts water and dish soap in a large spray bottle. Shake to combine, and spray any visible ants with the solution. [3] X Research source
- The solution will stick to the ants and the dish soap suffocates the ants to death.
- This tactic only kills the ants that have been sprayed, so it’s good to use in conjunction with a method where the colony and queen is targeted too.
- If you have a problem with ants on a plant, you can spray the plant with dish soap and water to help get rid of the ants. The spray won't harm the plant, but will be effective against the ants.
-
Sprinkle talcum powder around entry points to your home. Use a baby powder or body powder that contains talc, and sprinkle it liberally around foundations, windows, and doors. This causes ants to scatter and turn the other way when they reach the talcum powder.
- Ants are unable to cross through the powder, but will be kept from getting into your home. You will need to kill any ants that remain behind inside your house.
-
Make a paste of sugar and borax to attract ants from the nest. Combine 1 part borax to 3 parts white sugar. Slowly mix in a little water until the solution forms a paste. Apply the paste to the inside of jar lids, and place the traps near points of entry, food sources, and other spots frequented by the ants. [4] X Research source
- Borax, or sodium borate, is a salt of boric acid. This compound is often used for cleaning purposes and is usually sold in the detergent aisle of a supermarket.
- Borax can be toxic if consumed, you should keep these traps away from small children and pets.
- Ants are attracted to the sweetness of the paste and take it back to the nest, where the queen consumes it. Eventually, the borax poisons all of the ants that ingested it.
-
Make a trap using boric acid and corn syrup. Mix together 1 tsp (4.1 g) of boric acid with ¼ cup (2.6 oz) of corn syrup. Place a few drops on a piece of waxed paper, and place the paper in an area that you see ants passing by. [5] X Research source
- Boric acid is available from pharmacies.
- The ants will carry the solution back to the nest, where it will be effective in wiping out the colony.
- Replace the drops daily until there are no more ants.
- You can store the mixture for up to 2 weeks in a sealed container at room temperature.

-
Use insect sticky traps to monitor an area for ants. Place sticky traps along the edges of walls, and any other places where you think the ants could be travelling. Traps that are placed 5–10 feet (1.5–3.0 m) apart in places where the ants are likely to travel are the most effective. [6] X Research source
- Sticky traps are also effective for other non-flying pests such as cockroaches, spiders, and mites.
-
Place ant bait stations around your home. Purchase ant bait and place a station in every room that has an ant problem, focusing on areas where ants gather most often. Continue to refresh the bait until the ants stop showing up. [7] X Research source
- You can purchase ant bait stations from many supermarkets, department stores, and garden centers.
- Check the instructions of the ant bait stations for information about whether the product is safe to use with pets and children. Many products will specify placing the stations out of reach from children and pets. [8] X Trustworthy Source National Pesticide Information Center Organization run by Oregon State University providing objective, science-based information about pests and pesticides Go to source
- The ant bait will kill the ant that has consumed it, and the other ants will eat the body and will receive the poison too.
-
Spray visible ants with ant spray. Purchase a consumer spray pesticide specifically labeled to work against ants. Follow the instructions, spraying visible ants and perimeters in the manner described on the label. [9] X Research source
- Ant spray can be purchased from most grocery stores, garden centers, and department stores.
- It is absolutely crucial that you follow the instructions on the label. Not doing so can prevent the product from working and may even pose a health risk to you and your family.
- Make sure to use a pesticide labeled for use with ant problems. Some pesticide and insecticide chemicals are more useful against some insects than they are with others, so an insecticide meant to work on bees, for instance, may not work against ants.
- Some sprays kill ants instantaneously. Others coat the ants with a toxic chemical, killing them gradually so that the poison has a chance to get back to the nest first.
-
Call an exterminator if you get repeat infestations. Many ant problems can be solved at home with consumer products or natural solutions, but some severe infestations may require the help of a professional exterminator. Exterminators can quickly locate and kill the colony. [10] X Research source
- The exterminator will be able to assess the situation and determine which chemical will prove most effective against the ants. Chemicals used by professional exterminators are often more powerful than those available to consumers.
- Different species of ants require different treatments. A professional exterminator will be able to determine what species of ant you're dealing with and recommend the best solution. [11]

You should also trim back foliage that touches the outside of your house, like tree branches and vines, so ants can't use it to find their way inside. Also, try to keep your kitchen and dining areas as clean and free of food scraps as possible.

- The bait stations and liquid traps are awesome. Just make sure that you replace them every few days whenever you see dead ants in them. They tend to dry out kind of fast and stop working after 2-3 days in my experience.
- Soapy water works perfectly fine for me. I don't know why everyone else seems to need vinegar, alcohol, or pesticides. I just spritz the ants with a little soap water and they die a few seconds later. Easy!

If you want to naturally kill ants that are coming into your home, spray any ants you see with vinegar to kill them directly. You can also lay out a mixture of half powdered sugar and half baking soda, since any ant that eats this mixture will die. In addition, you can spread small piles of cornmeal by entryways so ants will take it to their colony and eat it, only to die of starvation a few days later. Keep reading to learn how to use commercial pesticides and when you should call an exterminator.
