Florida battles slimy invasion by giant African land snails

ORLANDO, Florida (REUTERS) - 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 molluscs are being caught each week in Miami-Dade and 117,000 in total since the first snail was spotted by a home owner in September 2011, said Ms Denise Feiber, a spokesman for the Florida Department of Agriculture and Consumer Services.

Residents will soon likely begin encountering them more often, crunching them underfoot as the snails emerge from underground hibernation at the start of the state's rainy season in just seven weeks, Ms Feiber said.

The snails attack "over 500 known species of plants... pretty much anything that's in their path and green", Ms Feiber said. In some Caribbean countries, such as Barbados, which are overrun with the creatures, the snails' shells blow out tires on the highway and turn into hurling projectiles from lawnmower blades, while their slime and excrement coat walls and pavement.
