How to Make Flea Medicine for Cats

The citrus in lemon juice kills and repels fleas. Spraying your cat with a lemon juice mixture is a safe, chemical-free way to control fleas on your pet. This natural lemon flea spray for cats can be made for less than a dollar. It smells pleasant, works well and is safe for you, your cat and the environment.


Step 1

Fill a medium-size sauce pan with 2 cups of water. You are boiling more water than you need to account for evaporation. Heat the water over high heat until it is rapidly boiling.

Step 2

Slice one lemon, with the rind on, into thin slices using a knife. The rind contains strong citrus oils. The exact thickness of the lemon slices is not important. Put the lemon slices into a large bowl.

Step 3

Measure 12 ozs. of the boiling water in a measuring cup. Be careful not to spill the water; it will be very hot and could cause third-degree burns. Pour the water into the bowl over the lemon slices.

Step 4

Leave the lemon slices to soak in the water overnight.

Step 5

Line a kitchen colander with a cheese cloth. Set the lined colander inside of a large bowl. Pour the lemon slice and water mixture into the colander. The colander and cheese cloth will catch the lemon slices and lemon pulp, allowing the lemon water to fall through, into the bowl.

Step 6

Pour the strained lemon water into a spray bottle.

Step 7

Shake the lemon water before use. Spray the lemon water on your cat up to once a day. Be careful to avoid your cat's eyes, nose, mouth and genital areas.
