A few drops of your favorite essential oil on your return air filter and your whole house is freshened with your favorite natural scent. It's so much healthier than synthetic man made air fresheners wafting through your home. Try lavender, orange, lemon, or ( my favorite ) clary sage.
remember....Borax ant bait. Borax is the most common ingredient in house ant control products, and get this: it's absolutely 100% natural. The best way (in my opinion) to use Borax is to mix 1 cup of warm water with 1/2 cup of sugar, and 2 tablespoons of Borax. Then soak the Borax mixture up with cotton balls and place those cotton balls near any trails the ants have established in your home. Feeding frenzy... tomorrow they'll be gone. I knew there had to be a way to do this naturally!
