I'm sure everyone would like to fight pests as naturally as possible. I, myself, prefer to use non-toxic products as often as possible, especially when it comes to my pets health. So here you go.
8 oz. apple cider vinegar
4 oz. warm water
1/2 tsp. salt
1/2 tsp. baking soda
Mix dry ingredients first then slowly add to wet as the vinegar and baking soda will react slightly. Put into spray bottle and spray pets down. Be careful not to get in pets eyes.
Use Borax throughout the house, sprinkle it on the carpets and let sit for a few hours, then vacuum. This should kill all the fleas and ticks in your home and on your pets.
