Buy farm-fresh cayenne pepper from the store or pick it from your garden to make cayenne pepper spray:

  1. In a cooking pan, combine 1 gallon of water and two tablespoons of cayenne pepper, and cut into small pieces to make a cayenne pepper deterrent
  2. Allow the pepper spray solution to reach the boiling point over a high-medium flame. Turn down the heat to low and leave it to simmer for 15 minutes.
  3. Turn off the flame. Allow for it to sit in the pan for 24 hours.
  4. After a day of rest, strain the mixture through a sieve, and this removes the pepper pieces from the pepper spray.

This spray can be used for up to two months and loses its potency afterward. Keep your distance when the mixture boils because the vapors can irritate your nose, throat, and eyes. Cayenne powder or crushed flakes can be substituted if fresh cayenne pepper is unavailable.
