If you find specific entry points where ants are coming into your home, focus your repellant and deterrent efforts on these areas. [1] X Research source That way, you reduce the chances of the ants reentering you home through these avenues.
When in doubt for what kind of ant bait to use, consider getting one of each. [3] X Research source If you find that the ants are not taking the bait, you may have to change the type of bait you are using, or relocate the bait to a more active area. [4] X Research source When using bait, all other food competition must be removed from the area. [5] X Research source This food competition could inhibit the effectiveness of the bait. When the ants start feeding on the bait, leave them alone to feast and bring it back to their colony. After some time, you should see a reduced number of ants.
Consider setting this bait at night, because ants tend to hunt for food during the night hours. You could also make a poison mixture with Borax and powdered sugar. Mix together 1 part Borax with 3 parts of powdered sugar. [9] X Research source Fill small containers with this mixture (bottle caps, spoons, etc. ), and place these containers around areas where ants may be entering your house. If you have pets or children who could get into this powdered Borax mix, consider mixing 1 cup of warm with ½ cup of sugar, and 3 tablespoons of Borax. Soak cotton balls in this mixture, and set the cotton balls out in shallow dishes near known ant entry points. [10] X Research source
Latex and siliconized acrylic caulks are not effective when trying to seal ant entryways, because ants can break down these caulking treatments. [12] X Research source
Consider keeping mint or chili pepper plants around your house or planting them in your garden. [14] X Research source These plants are known to keep intrusive ants at bay. You could also lay down a ring of food grade diatomaceous earth around the perimeter of your house or garden. [15] X Research source Sprinkle this powder near from your home’s foundation or garden, and try to sprinkle a ring around known anthills and nests. Diatomaceous earth breaks down the ants’ exoskeleton and causes them to dehydrate. DE is non-toxic to humans, but try your best not to directly breathe in powder particles. [16] X Research source Commercial insecticides can be used on the outside of your home, but bear in mind that insecticides are usually dangerous to humans, pets, and sometimes the environment.
You could also use vinegar to remove scented trails. Simply spray white vinegar over areas known for a lot of ant activity, and wipe down surfaces where you have seen ants before. [18] X Research source

Consider pouring a small amount of bleach or vinegar down the sink drain to help clear away any remaining food particles that could attract ants. [24] X Research source
Consider keeping baking goods (sugar, flour, etc. ) and cereals in airtight containers or bags.
