Make your own pest control spray using items you already have in your kitchen. Blend together 10 garlic cloves (husks included), one tablespoon of crushed red pepper flakes, and two cups of water. Strain the mixture through cheesecloth into a jar. Pour the mixture into a spray bottle, then add about one teaspoon of biodegradable dish soap. Spritz contents on plants that are infested with bugs. You may have to repeat for a few days, especially after a hard rain.
