How to deter cats with pepper spray

Updated June 18, 2018

Cats, like most animals, do not like the scent of pepper. It irritates their nasal passages. The good thing about pepper is that it can be used to keep cats away from unwanted areas in and around your home. If, for example, your cat likes to claw up your sofa, you can apply a pepper solution and the cat will stay away. You can do the same thing in a garden if you find that a cat is urinating in that area.

Pour 1 cup of distilled water into a spray bottle.

Grind 3 tsp of red pepper flakes in a grinder and add it to the spray bottle.

Shake the spray bottle to combine the ingredients.

Spray over any area in the house that you want to deter your cat from going.

Repeat once every two weeks.

Measure and pour 2 Tbsp of cayenne pepper in to a plastic zipper bag.

Add 3 Tbsp of powdered mustard, and 5 Tbsp of flour to the plastic zipper bag.

Close the zipper on the bag and shake rapidly to combine all three ingredients.

Sprinkle your homemade pepper cat deterrent outdoors in the areas you want to keep cat-free.

Repeat every two weeks or after it rains.


Always check an inconspicuous area inside your home (carpet or couch fibres) to make sure the pepper spray won't leave a stain.
