Python Lures Fail: Everglades Snakes Elude Scientists

Florida scientists have struggled to effectively detect invasive Burmese pythons in the Everglades using novel scent-based methods. A recent study involving female pythons as live lures in cages for 90 days failed to attract wild males, yielding only three detections from over three million camera trap photos. Researchers suspect that the stress of captivity may have inhibited the female pythons from releasing attractant pheromones.

Further complicating detection efforts, a separate study testing mammalian scent lures, specifically rabbit scent, also proved unsuccessful. Over 84 days, these lures did not significantly increase python sightings compared to plain soil. These failed scent experiments underscore the difficulty in locating these apex predators that have decimated native mammal populations.

Despite these detection challenges, ongoing removal efforts are showing steady progress. The Conservancy of Southwest Florida has removed approximately 20 tons of pythons over the past decade, utilizing a successful 'scout' snake program. This strategy involves radio-tracking male pythons during the breeding season to locate breeding groups and remove females before they lay eggs.

Similarly, the South Florida Water Management District has removed over 15,650 pythons through its Python Elimination Program, which employs paid hunters. Annual events like the Florida Python Challenge also contribute to removal efforts, with 195 pythons caught in 2024. These combined efforts are beginning to show localized impacts, with fewer large pythons being observed in certain areas.
