Neem oil, made from seeds of the neem tree, is available online or at garden nursery stores and some discount department stores.


Take 1 gallon of water and add 2 tablespoons (29.6 ml) of neem oil.
Add 1/2 tsp. (2.46 ml) each of rosemary and lavender essential oils. Essential oils can be purchased online, at local health food stores or co-ops, herb shops, vitamin stores or farmer's markets.
Add 2 tbsp. (29.6 ml) of liquid detergent to make the insecticide more effective.
Mix thoroughly and pour into a spray bottle.

Make a mixture of neem oil, essential oils of rosemary and lavender, and water for a natural insect killer that may also kill fungi and mites.
Spray your plants, mixing the solution frequently as you spray because oil and water separate.
