When it’s cold and wet outside, be on the lookout: That's the time when ants are on the march towards your kitchen, looking for warmer, sugar-stocked climes to hide out in for the winter. The solution? Make a bottle of this potent natural spray to use on your window and door frames, baseboards, and anywhere else the little critters tend to sneak into your home.

There are plenty of ways to prevent ants from taking over indoors. Natural options include leaving out capfuls of Borax and sugar to trap the little guys, or putting a few drops of tea tree oil on cotton balls, then stashing them in the corners of your pantry.

I’ve found this super-mentholated spray to be the most effective remedy, though, since it wards off ants before they’ve gotten a chance to invade. You can find Castile soap and essential oils at any health food store, or order them online. While it can be a little pricey to stock up on these supplies, I do use them in many other natural beauty and cleaning products, and a little goes a long, long way.
