After I researched moth balls being used outdoors turns out it is not a good idea and very toxic to the soil and environment.
Here is an environmentally safe, homemade recipe to try instead! @riverflows
First fill a one gallon container, such as a milk jug, with water. Crush 5 garlic cloves and add then to the water. Add a teaspoon of crushed red peppers and 1 tablespoon of dish soap.
Shake the container very well and then place in outdoors in the direct sun for two days. This is to allow the ingredients to permeate the water.
To use, shake the container well and then pour or spray the solution on the plants you want to protect from rabbits.
