To eliminate black ants from the house, put sticky tape near attractive items, insert boric acid into cracks and corners, draw chalk or sprinkle salt or talcum powder around entry points and discourage them with lemon juice or cayenne pepper. Get rid of ant nests by spraying them with a mixture of vinegar and water.
Discouraging ants from attractive edible items is an effective way to keep them out of the home. To keep insects away from goodies such as sugar and cookies, create a physical barrier with sticky tape.
Boric acid can effectively kill pests such as ants. To use it in the home, insert the powder into corners and cracks using a turkey baster. Homeowners with pets or small children should take care when using boric acid, as it can also be toxic to humans or animals if they eat any of the powder.
Barriers around entry points to the home can also help get rid of ants. Chalk, salt and talcum powder are all unattractive to ants. Draw lines with chalk or sprinkle talcum or salt around windows and doors to keep ants from entering the house.
Lemon juice, spices and herbs can be appealing to humans, but they are unappealing to ants. Spray lemon juice around entry points in the home and around cracks and crevices. Wash surfaces with a mixture of lemon juice and water. Put bay leaves in containers and use spices and herbs such as cinnamon, cloves and sage to make sachets for cabinets. Sprinkle cayenne pepper around baseboards and cabinets.
To remove ants from their source, mix one part vinegar with one part water and add the mixture to a spray bottle. Spritz the vinegar mixture on ant hills and nests to remove ants from the property.
