ORLANDO, Fla. -- South Florida is fighting a growing infestation of one of the world's most destructive invasive species: the giant African land snail, which can grow as big as a rat and gnaw through stucco and plaster.
More than 1,000 of the mollusks are being caught each week in Miami-Dade and 117,000 in total since the first snail was spotted by a homeowner in September 2011, said Denise Feiber, a spokeswoman for the Florida Department of Agriculture and Consumer Services.
