34. Attract Beneficial Insects
While many of the items on this list have dealt with how to avoid insect pests, there are actually several insects that are beneficial to gardens. Praying Mantis and Ladybugs are two incredibly helpful insects that help keep your garden safe by eating problematic bugs like aphids.
Some garden catalogs offer to ship Praying Mantis egg sacs and live Ladybugs directly to your door for introduction into your garden. Yarrow, Angelica, Cosmos, and many other flowers are attractive to both Mantis and Ladybugs; they will help make your garden home to beneficial predatory insects.
