The colony consumes approximately 2.5 billion insects nightly.
The bat houses were relocated to their current site in 2017 to accommodate campus construction.
Brazilian free-tailed bats are capable of flying at speeds of 60 miles per hour.
The structures utilize a specific ventilation design to maintain the high internal temperatures required by maternity colonies.
In 2009, a major structural collapse occurred, requiring the construction of the current larger facilities.
The project is overseen by the Florida Museum of Natural History.
The UF Bat Houses are one of the world's largest occupied bat roosting sites, housing an estimated 450,000 to 750,000 bats. The colony consists primarily of Brazilian free-tailed bats, southeastern bats, and evening bats. These structures were originally built to provide a safe alternative habitat for bats that were displaced from campus buildings. The bats emerge en masse at dusk to feed on insects, creating a visible stream that can last for fifteen to twenty minutes. The site is managed by the University of Florida to support pest control and biological research. Visitors observe the colony from a designated viewing area located a safe distance from the structures. The bat houses serve as a biological experiment to determine if artificial roosts can sustain large populations. This colony provides significant ecological benefits to the local Gainesville area by consuming tons of agricultural and garden pests nightly.
The designated viewing fence offers the best perspective to capture the bats silhouetted against the twilight sky.
Arrive well before sunset to secure a spot at the viewing fence.
Bring mosquito repellent, as the humid Florida environment is active during dusk.
Remain quiet and avoid using flash photography to prevent disorienting the bats during their emergence.
Do not stand directly beneath the flight path of the emergence, and avoid using bright white lights or flash photography.
Emergence activity is significantly reduced or absent during cold weather months when bats remain inside to conserve energy.
Keep noise levels low, stay behind the viewing fence, and do not attempt to touch or feed the bats.
