How to Make Dog Repellent for Mulch


Mulch helps protect plant roots during the winter months and also helps keep weeds from sprouting and stealing essential nutrients from the plants. Unfortunately, if you own a dog that likes to dig, you could be at risk for the dog discovering the mulch and digging it up. It is best to make a homemade dog repellent and use it on your mulch before your dog has a chance to ruin your hard work.

Pepper Mixture

Step 1

Pour 1/2 cup of cayenne pepper in a small bowl. When a dog sniffs cayenne pepper it begins to irritate its nose. Your dog will not like this and will stay away from your mulch.

Step 2

Add 1/2 cup of black pepper to the small bowl and mix the two peppers together. Black pepper when sniffed by your dog will make it sneeze. Again, it is another irritant that your dog will want to stay away from.

Step 3

Sprinkle the pepper mixture over the mulched area.


Step 1

Place cotton balls in a bowl. The number of cotton balls needed depends on the size of the mulched area. A small area may only need 20 cotton balls, while a large area could use double that.

Step 2

Pour ammonia over the cotton balls and allow the ammonia to soak in to the cotton balls. Dogs have a heightened sense of smell and hate the smell of ammonia.

Step 3

Place the cotton balls all around the area you mulched. You can do this in conjunction with the pepper mixture.

Tips and Warnings
