Ladybugs
If you’re not gardening with ladybugs, you really should try it. These pest-killers can be purchased from many farmer’s markets, and are an incredible natural insecticide. Simply release a bag of little red ladybugs into your garden and they’ll do the hard work for you, eating all the aphids that would otherwise munch on your plants. Don’t worry: ladybugs are carnivorous, so won’t eat your leaves.
