Giant African land snails (GALS) were found in Miami-Dade County in September 2011 and in Davie, Broward County, on September 9, 2014. Ongoing eradication efforts by FDACS have brought significant decline in the snail population, and most snails now being found by the inspectors are dead. Nevertheless, the public is urged to continue to be vigilant. Most of the snail finds have resulted from reports from residents. The snails can grow to be eight inches long and attack more than 500 plant species. They consume stucco to obtain calcium to build their shells and can damage buildings. They are known to carry a parasite that can spread a form of meningitis to which humans and animals are susceptible. Below are key numbers related to the eradication program.
