Chalk lines aren’t just for crime scenes anymore. There’s speculation as to why ants avoid chalk, but most believe it’s due to the calcium carbonate in chalk. Whatever the reason, ants will rarely cross a chalk line, so just draw some lines around doorways and windows to keep the ants from getting into your house.
2. Peppermint spray
Unlike humans, ants hate the smell of peppermint. Now, you could unwrap a bunch of peppermint candies and strategically place them all over your house to repel ants. Or, you could make your own peppermint spray using distilled water, 2 tablespoons of witch hazel, and 12 drops of peppermint essential oil. Combine these ingredients in a spray bottle, shake it up and spray it wherever the ants seem to be coming in. It’s a natural remedy that will leave your house smelling great.
