How To Make Home Made Organic Pesticides

With growing concerns about the environment and the long term impact of chemicals on soil and our food supply, many homeowners have turned to making their own organic pesticides. Homemade agents to get rid of unwanted pests and weeds is not a new concept, and farmers have been fighting invasive insects as long as humans have been growing food.

Common Ingredients

Most ingredients for organic pesticides are easily found and are quite economical. For the most part, if you look in your kitchen pantry you can find the basic foundational items that are found in most natural weed or pest killers. When attempting to kill insects, the primary goal is to stop the pest from invading your plant. You can accomplish this by making the plant unappealing or distasteful to the insect or by tricking the pest into thinking that the plant is poisonous to them.

Common methods include using:

  • spicy ingredients (peppers, garlic, horseradish)
  • nicotine 
  • soap

Soap Spray

Liquid soaps are very effective in killing almost any insect found on plants. This includes aphids, mites and thrips. Not only does the soap make the plant unappealing, but it can also suffocate the insects if sprayed directly on them.

The materials include:

  • ¼ Cup Liquid Dish Soap – Use a gentle soap like Dove that is actual soap, not a detergent, since detergents will burn plant leaves.
  • 1 Quart Warm Water

Blend the two ingredients and then pour them into a spray bottle. Spray the mixture on plants that are infected. If possible, spray directly on insects.

Nicotine Spray

Organic pesticide sprays made of nicotine or tobacco are great for combating a combination of pests. This can include worms, aphids and caterpillars. Nicotine spray should not be used on eggplant, tomato or peppers, since it will kill these types of plants.

The materials include:

  • 1 Cup Tobacco – You can find tobacco by purchasing it at a natural food store or simply unraveling several cigarettes from their paper.
  • 1 Gallon Water

Mix the tobacco with the water and set aside for a minimum of 24 hours. When the mixture is ready, it should be the color of weak tea. If you discover that it is too dark, then dilute it with additional water until the right color is reached. Strain the mixture through a fine sieve or cheesecloth to remove the tobacco. Pour into spray bottles and spray on plants or insects.

Garlic and Pepper Spray

Garlic and pepper are very spicy ingredients that insects find unappealing. It works great for fighting slugs, fleas, mites, cut worms and tomato worms.

The materials include:

  • 1 Bulb Garlic
  • 1 Medium Onion
  • 1 Tablespoon Cayenne Pepper
  • 1 Tablespoon Liquid Soap
  • 1 Quart Water

Crush and mince the garlic until it is a fine paste. Cut and mince the onion. Mix the garlic and onion together. Add the pepper and water. Let the entire mixture sit and steep for a minimum of 1 hour. Strain the mixture through a fine sieve or cheesecloth and then add the soap. Pour the mixture into spray bottle and spray on plants. Any unused mixture should be stored in the refrigerator and will last up to a week.

There are literally hundreds of recipes for natural and organic pesticides that can be used in the home and garden. Probably one of the most simple is to pour boiling water directly on unwanted bugs or plants. Within a matter of minutes or days, they will die. Eco-friendly methods of pest control have been used for centuries and are easy and simple to use today.
