Some natural pet products on the market contain citrus ingredients to repel and kill pests. Orange and lemon pills smell nice -- certainly nicer than other insecticides -- and are safe for your family and pets. If you'd like to avoid spraying your home with toxic chemicals, try making a simple, homemade flea spray with citrus peels and water.
Boil five orange or lemon peels in a pot with four or five cups of water until the peels become soft.
Take the pot off the stove and allow it to cool completely.
Liquefy your peel and water solution in a blender.
Using a piece of cheesecloth, strain the solution into a glass jar.
Funnel about half of the solution into a spray bottle.
Pour the orange peel water on your pet after a bath.
Spray the solution throughout your home wherever fleas are a problem.
Spray again after four weeks, to eliminate any additional fleas that may have hatched.
