Organic Garden Pest Control

Organic garden pest control looks at managing garden pests naturally and realistically. Unwanted insects and weeds are the pests we are concerned with. Before spraying them to death, literally, and introducing poisonous chemicals into your environment, try your hand at organically removing them. Keep in mind complete annihilation is not the goal or even necessary.

Through organic garden pest control methods you can safely and effectively control your pest populations without harming the beneficial organisms and desirable plants in your garden. For more details on these methods read the related articles on organic pesticide and organic weed control .

This article is mainly concerned with giving you some homemade alternatives for your organic garden pest control needs that will kill unwanted pests safely.

Organic Garden Pest Control Recipes

Homemade Organic Pesticide

The most common of all homemade pest control remedies is the soap spray. Soap is safe for your vegetables and leaves no residue. It kills soft-bodied insects such as mites and aphids. Hard-bodied insects will need additional treatments.

Oil sprays make good insecticides and fungicides with the right ingredients. These will only work on pests that remain on plants. Some plants can be burned with oils so remember to test your spray. Spray tops and bottoms of leaves in warm weather.

Soap Solution
easy to make insecticide soap spray

• 2 tablespoons of dishwashing liquid
(I’d use an eco-friendly brand)
• 1 gallon warm water

Mix ingredients and fill a spray bottle. You can add sulfur (according to package directions) or 1 to 2 T of baking soda to kill fungi as well as insects.

Oil Spray Recipe
    • 1 cup of vegetable oil
    • 1 tablespoon of dishwashing liquid
    (I’d use an eco-friendly brand)
    • 1 tablespoon oil mixture
    • 2 cups water

First, combine oil and dishwashing liquid in a jar or plastic squeeze bottle. Set aside. In a spray bottle make solution using 1 T of oil mixture (less for sensitive plants) and water.

Tip: Shake bottle every so often while applying as water and oil don’t mix. Re-apply after a week as needed.

Garlic Oil Recipe

    • 1 whole garlic minced
    • 1 cup vegetable oil
    • 2 teaspoons garlic oil mixture
    • 1 quart water
    • A few drops dishwashing liquid

    First prepare garlic oil mixture by combining garlic and oil. Refrigerate for a day or two. Strain out garlic. Mix remaining ingredients with 2 tsp of garlic oil mixture. Spray as needed. Garlic oil works on insects, mold and mildew.

Homemade Organic Weed Killer

Vinegar can be used un-diluted or mixed into a spray. You can also make solutions with a few tablespoons of either alcohol or soap in a quart of water.

I can’t stress how important it is to take care not accidentally spray your desired plants as all these solutions are deadly. Shield your plants with cardboard or plastic dome. Don’t spray when it’s windy.

Vinegar Solution
    • 1 cup vinegar

    • 1 cup water

Mix ingredients and fill a spray bottle. You can use vinegar full strength but it can alter the pH in the soil so use caution.

Bleach Solution
    • 1 cup bleach

    • 1cup water

Mix ingredients and fill a spray bottle. You can use bleach full strength for tough weeds.

All of these recipes should be used sparingly and conservatively. At the risk of sounding like a broken record, keep in mind that eventhough these are organic garden pest control remedies, they will also destroy the "good guys,” too.

If you must use them, at least you can rest assured that they are benign, not harmful, to your family, pets, the environment, or you.
