I use a garlic pesticide made up as follows: 10 – 12 Garlic cloves and 1 liter water. Blend and then stand for 24 hours, strain and add one tablespoon cayenne pepper and stand again for 24 hours, strain and place in a glass jar in a cool place. Mix 1/2 cup to 4 liters water and spray every 7 days. Works like a charm.
I use diatomaceous earth on my plants to keep them bug free. Seems to be working so far and I don’t have to worry about poisons or any side effects to my plants.
