Since September, giant African land snails have put a roughly 300-acre zone in Hialeah, Florida, on high alert, with state authorities restricting movement of yard waste and bricks without permission. Scientists patrol the area to find the mollusks, which grow up to eight inches but are often cited as nine inches for headline impact, and can spread the rat-lungworm parasite. Florida has spent millions since 1969 fighting three infestations, one lasting a decade.
When snails are found, inspectors from the Division of Plant Industry set bait, apply anti-mollusk poison to soil, and distribute public mug shots to raise awareness. An area is deemed clean only after three years of monitoring and treatment. Paul Skelley, a key architect of the state’s crackdown, said the current outbreak appears limited to one city block but emphasized a full-bore response: “We are serious about this snail in Florida… you need to cut them out.” Skelley, who also led the response to the 2011–2021 infestation, described the snails as “meaty and sweaty-looking, like a boxer’s fist,” and warned that if they spread, they could travel up the East Coast via human transport.
The snails pose agricultural hazards by eating beans, melons, flowers, and shrubs, damage stucco and tires, and have previously blocked roads in Hawaii and overwhelmed schools in India. Climate change may expand their range further.
