1 lemon
2 cups (500ml) water
To prepare a homemade flea spray, cut the lemon into 4 to 6 pieces and place in a large glass bowl. Bring the water to a boil and pour over the lemon pieces, then let the mixture sit overnight. In the morning, strain the liquid and transfer to a spray bottle. Use to spray your dog or cat generously from head to tail, especially behind the ears (be careful to avoid the eyes).
