Organic garden use can be made without using any dangerous chemicals. Want to know how to kill weeds without using pesticides? These homemade organic weed killers are non toxic, natural, cheap and effective. Natural pesticides use common ingredients that are easily accessible. Here are a few of the best:
Outdoor Options:
Tobacco Spray – Tobacco has long been used as a natural pesticide because the nicotine in it kills many kinds of pests, including aphids, caterpillars, beetles, potato bugs, and even some fungi. It should not be used on tomatoes, peppers, or eggplants but is safe on most things in your garden. It’s also quite easy to make. Simply soak organic tobacco in water overnight. Some suggest boiling it is also effective and that the heat helps to release the nicotine. The water should be light brown, so if it becomes dark you can add more water to it. You can “paint” the leaves of your plants or spray the water on plants to discourage most pests.
Diatomaceous Earth and Chili Pepper – 1 cup Diatomaceous Earth mixed with powdered dried chili peppers and 2 liters of water and allowed to sit overnight makes an effective spray for outdoor plants. The chili pepper will also repel cats and rabbits from your garden.
Indoor Options
Garlic, Onion & Chili Pepper Spray – This is one you can make cheaply with things already in your kitchen. It should be refrigerated and is good for a week. It takes one garlic bulb and one small onion, finely chopped, one teaspoon of chili powder and a quart of water. Steep the mixture for an hour, strain the mixture and add a tablespoon of dish soap to the water. You can coat your indoor plants with this to keep your cats from bothering the plants and it will also repel pests.
Orange Oil Water – You can buy commercially prepared orange essential oils and add to water, or you can save orange rinds and boil them in water to make your own infused water. Add a tablespoon of castile soap or dish soap. Simply spray your plants and repel pests while also making your home smell nice.
