The snails were first discovered in Miami in September 2011, [_AFP_ ](http://www.afp.com/en/news/floridas-giant-snails-prove-be-slippery-foe)[reports](http://www.afp.com/en/news/floridas-giant-snails-prove-be-slippery-foe), the first invasion since the 1960s. Since then the species has spread to new territory, including the southern suburbs of Miami and the neighboring Broward County. “The fact is they’re a human and animal health threat and they’re a threat to Florida’s agriculture. We can’t let the population continue,” said Mark Fagan, a spokesman for the state agriculture department. The giant African snails have continued to elude the state’s eradication efforts, which can prove fruitless when the gastropods climb trees to avoid chemicals on the ground, or hibernate below the soil for months at a time. Still, over 158,000 giant African snails have been removed in the past four years, with the last sighting reported in April, officials said. Two years must pass since the last snail is found alive in the wild for the state to declare the species eradicated. \[[_AFP_](http://www.afp.com/en/news/floridas-giant-snails-prove-be-slippery-foe)\] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3981509/giant-african-snail-florida/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3981509/giant-african-snail-florida/"},"headline":"Giant Snails the Size of Tennis Shoes Are Waging Terror in Florida","datePublished":"2015-08-02T19:19:09.000Z","dateModified":"2026-08-04T07:48:17.071Z","description":"The invasive snail was discovered in Miami in 2011","url":"https://time.com/3981509/giant-african-snail-florida/","keywords":["Newsfeed","animals","States","Florida"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt6ea2603a666af6bd/69885d7b196cf4fa8e0375dc/giant-african-snail-florida.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Jack Linshi","jobTitle":null,"url":"https://time.com/author/jack-linshi/"}],"articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt6ea2603a666af6bd/69885d7b196cf4fa8e0375dc/giant-african-snail-florida.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Giant African Snail Florida","caption":"Giant African Snail Florida","creditText":"Joe Raedle—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/tag/time-section-newsfeed/","name":"Newsfeed"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/3981509/giant-african-snail-florida/","name":"Giant Snails the Size of Tennis Shoes Are Waging Terror in Florida"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"Overstepping Boundaries: The Danger of Invasive Species","description":"What are invasive species, and why are they dangerous?
