Use about a cup of baking soda and just 5 or 6 drops of essential oils. Orange is a good choice. Just mix them together and place them in a shaker – an empty parmesan cheese container works great for this. For fleas add about 2 tablespoons of borax to the mix and it will take care of those little pests. Tea tree oil works just as well as borax and eliminates flea issues perfectly.
