Bats bring a beneficial component to your property and community. This flying mammal is an exceptional nocturnal feeder of many insect pests and they are important pollinators of many food plants. However, several challenges face this night flyer, like reduced roosting locations, reduced foraging sights, and over use of pesticides.

There are ways to attract bats to your backyard, farm, and community. Placement of bat boxes with ample water sources nearby is a good start. Water sources are another area of importance to attract bats. Have you sat by a swimming pool and witnessed a bat swoop down and skim across the water? It is likely they are either consuming a little water after feeding on a large number of harmful insects or are wetting their modified arms (wings) to help remove dust and dirt to reduce drag on their wings. Bats are the only mammal that are capable of true flight, the modified wings with skin spanning between specific bone structures allows them to accomplish this amazing action.
We often refer to bats as blind, but they can see shadows if out during daylight hours. This poor sight is not helpful enough for survival, this is where their echolocation abilities come into play. Humans studied bats to better understand how they make the sounds that bounce of an object and back to their sensing system that includes exceptional hearing. They locate and consume insects this way. If this sounds familiar, sonar systems were developed by studying this process.
Bats are the major harvester of night-flying insects, many that carry diseases that impact humans and other animals. Insect prey for bats include cockroaches, mosquitos, moths, beetles, gnats and others. A Big Brown Bat can catch and consume 3,000 to 7,000 mosquitos a night. Multiple this by a large bat population the amount of harmful insects harvested can go into the thousands of tons in a year. This is a positive impact for our forest and agriculture lands against major pests.
Florida is home to 13 different species of bats. They are always on the hunt for warm, dry, dark areas that are either natural or manmade narrow crevices. Out of all of these species, 4 bats are the primary inhabitants of bat houses. The Evening Bat and Brazilian free-tailed Bat are the most common in the panhandle of Florida. The Big Brown Bat and Southeastern Bat can at times occupy houses.

You can often locate bats boxes at your garden and agriculture centers or order online. Another option is to build your own boxes. Just remember the best way to erect a bat box is on a tall post. It is recommended to set the boxes around 10 feet off the ground. Placing boxes on trees creates a setting for potential predators to approach and feed on bats. Snakes have been known to enter and feed on young bats that are not fully developed and at best are poor fliers.
As a reminder, never touch a bat or any other wild animals. Bats that are healthy are not found on the ground, so assume the bat is not health and may be carrying a disease. On a final note, enjoy sitting on the back porch and watching the acrobatics of these amazing mammals in the evening sky.
The showy chaste tree makes an attractive specimen as the centerpiece of your landscape bed or in a large container on the deck. Much more of them are being seen since the Florida Department of Transportation has recognized the tree as a desirable median planting. Easy-to-grow, drought resistant, and attractive to butterflies and bees, Vitex agnus-castus is a multi-stemmed small tree with fragrant, upwardly-pointing lavender blooms and gray-green foliage. The chaste tree’s palmately divided leaves resemble those of the marijuana (Cannabis sativa) plant; its flowers can be mistaken for butterfly bush (Buddleia sp.); and the dry, darkened drupes can be used for seasoning, similar to black pepper, making it a conversation piece for those unfamiliar with the tree.
Vitex , with its sage-scented leaves that were once believed to have a sedative effect, has the common name “Chastetree” since Athenian women used the leaves in their beds to keep themselves chaste during the feasts of Ceres, a Roman festival held on April 12. In modern times, the tree is more often planted where beekeepers visit in order to promote excellent honey production or simply included in the landscape for the enjoyment of its showy, summer display of violet panicles.
Chaste tree is native to woodlands and dry areas of southern Europe and western Asia. It will thrive in almost any soil that has good drainage, prefers full sun or light shade, and can even tolerate moderate salt air. Vitex is a sprawling plant that grows 10-20 feet high and wide, that looks best unpruned. If pruning is desired to control the size, it should be done in the winter, since it is a deciduous tree and the blooms form on new wood. The chaste tree can take care of itself, but can be pushed to faster growth with light applications of fertilizer in spring and early summer and by mulching around the plant. There are no pests of major concern associated with this species, but, root rot can cause decline in soils that are kept too moist.
Crape myrtles are all around good tree selections for the landscape. When left in their more natural form with just a little selective pruning, crape myrtles can provide shade during our hot summer days. Learn the many qualities of the crape myrtle with UF IFAS Extension Escambia County.

In the Panhandle, fall is the prettiest season for wildflowers. Our roadsides and woodlands are covered with pinks, whites, yellows, blues, purples, and even a little red here and there. Pretty as it may be, the beautiful wildflower look isn’t super appropriate for most yards. It would look unkempt, a little “wild” if you will, would be hard to manage and is probably best enjoyed in natural areas. However, we can bring some of the native colors of fall into our landscapes in a much lower maintenance, refined manner with two Panhandle species that pair excellently together, Muhly Grass (Muhlenbergia capillaris) and Darrow’s Blueberry (Vaccineum darrowii).

Muhly Grass, the native grass with the pinkish/purple panicles blooming right now, has gained much popularity in recent years, earning a reputation as a near pest/disease free, drought tolerant, attractive landscape plant. Operating in lieu of more traditional low growing shrubs in landscapes, Muhly is an airy, greenish gray bunch grass growing about 3-4’ tall and wide, lending informal, coastal texture to landscapes most of the year and really shining in fall during its flowering season. Once established, it never needs extra water, prefers little fertilizer, and only needs a rejuvenation prune (or burn – the Leonard preferred method. It’s fun and mimics the role of fire in Muhly’s native ecosystems!) every couple of years to keep it looking tidy.
Unlike Muhly Grass, Darrow’s Blueberry has not caught on broadly in the landscape industry but is no less deserving. This native blueberry species only grows a couple of feet tall, produces edible fruit that wildlife enjoy, and adds an unusual blue green color to landscapes via its tiny-leaved, evergreen foliage. It prefers the same sites as Muhly and is part of the reason they pair so well together. Our mostly sandy, well drained soils work just fine, but both plants can handle soils that are occasionally wet. A bonus, Darrow’s also has tiny, bell shaped flowers in spring that attract all manner of beneficial bee species. This makes it a must in any native pollinator garden!
As good as these species are alone, I think they are better together. In my family’s yard, we created a loose screen of widely spaced (8’ apart) Muhly Grass specimens around a pool, in the spirit of giving the area a “coastal” airy feel, and interspersed Darrow’s Blueberry in between.

The look has been outstanding, particularly in the late summer/early fall. The pinky purple flowers of Muhly Grass complement the green-blue foliage of the blueberries nicely and provide easy, lasting color without having to worry about planting finicky annuals or perennials each season.
Landscaping with natives does not have to look wild and unkempt, nor does it have to be drab and unattractive. Combining native yet showy plants like Darrow’s Blueberry and Muhly Grass makes for an unusual, refined, nearly no-maintenance feature in your landscape. Look for these and other neat native plants at native nurseries and independent garden centers around the Panhandle. If you’d like more information on native grasses, blueberries or any other horticultural topic, please contact your local UF/IFAS County Extension Office! Happy Gardening!
