Natural Organic Pesticides For Green Gardening | Homemade Insecticide Sprays, with Only 2 Ingredients, it's Simple, Organic and Safe! by Pioneer Settler at http://pioneersettler.com/natural-organic-pesticides/
Homemade insecticide - 1 1/2 tsp. Castile soap and 1 quart of warm water. Add some tabasco sauce. Put in a spray bottle.
Natural Pesticide - Mix 1 gallon of water with 2 tablespoons of neem, and ½ teaspoon each rosemary and lavender essential oils (I used organic version of all the oils). You can also add a couple of tablespoons of phosphate-free liquid dishwashing soap. Mix thoroughly and pour into a spray bottle. Spray over every part of your plants, mixing frequently to keep the oils and water from separating.
