Every gardener has experienced it, usually more times than they can count. You walk into the garden and discover a plant that’s been defoliated or otherwise damaged by caterpillars. The canna leaves are riddled with holes, the cabbage leaves look like lace, half the tomatoes have worms in the fruit, or the azaleas have been stripped of their leaves. How could this happen so quickly?

Dragonflies with their ominous beauty, vivid colors and their spectacular flying maneuvers have provided hours of entertainment for many gardeners. Dragonflies are widespread across the United States and can be enticed to visit most yards. There are more than 450 species found throughout the United States and Canada. They range in color and size from the small eastern amberwing to the very large and brilliantly colored green darner. Although these insects tend to stay close to their birthplace, they are strong fliers that will explore surrounding areas. So if you garden even remotely near fresh water or a wetland, you can lure dragonflies to your yard.

Spiders are perhaps some of the most feared and misunderstood inhabitants of any garden.

Knowing how to live side by side in harmony is a simple matter of understanding what makes them tick – or twitch.

Their distinct vocalizations often give their locale away, as they fly silently with their fringed feathers hunting for vermin. Having pest control working not only for free, but throughout the night unseen, is an added bonus. Owls are an environmentally safe form of pest control – no harsh chemicals needed.

All bats found in the Southeast are insectivores and therefore provide the ecological benefit of acting as a natural pest control. Forty-five bat species are native to the United States with 15 living in the Southeast. Nearly 40 percent of these species are threatened or endangered, and around the world, many more are declining at alarming rates.
