Citrus
Harness the power of tangy citrus fruits like lemons, oranges, limes, and grapefruits to keep ants at bay. The natural acids present in these fruits work wonders by masking the scent trails of ants, at least temporarily. Squeeze lemons into a spray bottle or create a pureed mixture of orange peel and water to rub on window sills and door jambs. These methods will discourage the tiny insects from crossing over into your living spaces.
Coffee Grounds
A tried-and-true method for repelling ants is to sprinkle coffee grounds around the stems of both indoor and outdoor plants and flowers. Some claim that it is the smell of coffee that repels ants, while others believe that ants dislike the texture of the grounds beneath their feet. Regardless of the reason, this method has proven to be effective in keeping ants away.
