An Organic Farmer’s Experience with Bat Houses

Nearly 20 years ago, Frank Bibin, a Georgian pecan grower contacted Merlin for advice on attracting bats to help control insect pests in his orchards. He has since gone organic and become an important advocate for building artificial bat roosts.  To learn of his results go to Pebble Hill Grove–About Bats.

Frank’s first small bat houses were put up in 1998. This video, filmed in Frank’s pecan orchard, tells his early story. It took two years to attract the first bats. Thereafter, numbers grew rapidly. Now that local bats are accustomed to using bat houses, new houses are normally occupied within 30-40 days.

Through years of testing, he has developed many new innovations. His bat houses and mounting accessories are achieving nearly 100 percent occupancy at many locations in the Southeast and are available for purchase at Frank’s website, Pebble Hill Grove–Bat Houses . Parks and nature centers are among his primary customers.  Though there are many suppliers of smaller bat houses, we know of none better than Frank’s when it comes to long-lasting roosts that attract larger numbers of bats.

The story of Cave Nectar Bats’ contributions and requirements is complex and only beginning to be fully understood. These bats traditionally formed huge colonies in caves, 100,000 individuals in a single cave. However colonies are extremely vulnerable, and few large colonies remain. People commonly set nets over cave entrances, capturing large numbers to be eaten as a delicacy. Also, limestone quarries pose constant threats of permanent destruction of essential caves, and durian growers themselves sometimes kill large numbers.
