How to Make Organic Pepper Spray for Plants

watering plants image by david hughes from

There are a number of plants that attract deer, squirrels and rabbits. These animals will munch on your plants until there is nothing left. Your plants also have other predators that are interested in feasting on them. They include aphids and mites. There is a solution that will both repel the animals and kill the insects at the same time: An organic pepper spray acts as both a repellent and an insecticide.

Place 1/2 cup of jalapeno peppers in a blender.

Pour two cups of water in the blender and use the puree setting on the blender to combine the two ingredients.

Set the pepper water aside for 24 hours.

Strain any pepper pieces out of the water using a cheesecloth.

Pour the strained pepper water in an empty spray bottle.

Add five drops of liquid castile soap to the pepper water. The soap helps the pepper water stick to the plants so that it can do its job.

Spray on your plants.

Organic Pepper Spray For Insects

A discussion of organic pepper spray or any pesticide should include a discussion of integrated pest management (IPM). IPM uses predator insects to keep pests in check before resorting to pesticides. ( The EPA has approved capsaicin as a biochemical pesticide used to repel and kill insects. Mammals are repelled but not harmed. The impact on aquatic organisms is not well researched, so gardeners should avoid using pepper spray near water. Gardeners should wear gloves and goggles when applying pepper spray to plants. Spraying on windy days should be avoided. Pour the pulverized pepper into a gallon container and add enough water to make a gallon of concentrate. Wear gloves when preparing and using the spray.


You will need to reapply the pepper spray every two weeks, and after any heavy rainfalls.


Avoid spraying your plants when the temperatures is above 80 degrees F. First thing in the morning, or late at night is best.
