Sugarloaf Key Bat Tower, Historic bat tower in Lower Sugarloaf Key, Florida.

Sugarloaf Key Bat Tower is a wooden structure with multiple chambers designed to house bat colonies for mosquito control. The building demonstrates an early approach to natural pest management through deliberate use of bat populations.

Richter Clyde Perky, a fish lodge owner, built the tower in 1929 using plans bought from Charles Campbell of Texas, an early bat-studies pioneer. Campbell called the design the Hygiostatic Bat Roost, meant to house bats that would eat malaria-spreading mosquitoes. It was one of fourteen Campbell towers built worldwide. Hurricane Irma toppled it on September 10, 2017.

The tower appears in Tim Dorsey's novel Torpedo Juice, Neil Gaiman's American Gods and Tom Corcoran's Gumbo Limbo, and was discussed on the June 1, 2025 episode of Last Week Tonight with John Oliver. Local folklore credits the skunk ape with early damage to the structure and with driving off some of the bats.

The tower stood a mile northwest of U.S. Route 1 on Lower Sugarloaf Key at mile marker 17, reached via Bat Tower Road. Hurricane Irma toppled it on September 10, 2017; as of October 2017 it was undecided whether it would be repaired or re-erected. Check current access before visiting.

Fourteen Campbell bat towers were built worldwide, not three. Two remain standing in Texas, at Comfort and at Shangri-La Gardens in Orange; the Sugarloaf tower was toppled by Hurricane Irma on September 10, 2017. Local folklore blames early damage and the bats' departure on the skunk ape.
