Giant African Snail
Florida Department of Agriculture and Consumer Services.Florida Commissioner of Agriculture Adam H. Putnam announced today that more than 168,000 giant African land snails have been eliminated in Florida since the invasive snail was discovered in Miami-Dade County in 2011. In addition to threatening more than 500 varieties of plants and agricultural commodities, GALS consume plaster and stucco to get the calcium needed to grow their shells. Ninety-six percent of GALS initial finds have been identified due to calls to the helpline. To report a giant African land snail, call the department's toll-free helpline at 1-888-397-1517. To preserve a snail sample with gloved hands put the snail in a zip-top bag, seal it, and put in a bucket or plastic container. Do not touch the snails or release them in a different location.

See what states have a federal quarantine for any of the targeted Hungry Pests, and identify which pests or diseases are at greatest risk due to a suitable habitat. In addition to federal quarantines, state-level quarantines might apply see State Summaries of Plant Protection Laws and Regulations (National Plant Board).
