Have you ever heard of a “Garden Mini Insectary?” It is a small garden placed near or in your regular garden that attracts and hosts beneficial insects. These insects prey upon the many bad insects that prey on your garden. A natural way to control pests, a Garden Mini Insectary assures that you won’t have to use insecticides or other dangerous customers to rid your garden of bad pests.
You don’t need a large plot of ground to accommodate this type of garden. It just needs to be large enough to hold six or seven varieties of plants that attract the good insects.
Plants that would prove beneficial and the predator insects they attract include:
