The giant African land snail (Achatina fulica), which now terrorizes Florida, dines on more than 500 species of plant and will even devour stucco and other building materials. One solution to the snail invasion could be culinary. Floridians could learn from people in the snails' native Africa, where snail soup is a delicacy.
The giant African land snail joined a buffet of other edible invasive species in Florida, including: tiger prawns (Penaeus monodon) and lionfish (Pterois sp.) from the Gulf of Mexico, an aquatic rodent known as a nutria (Myocastor copyus) and feral hogs (Sus scrofa). Vegetarians with a taste for invasives can dine upon the kudzu plant. Kudzu cooks prepare the roots like potatoes, make salads of the leaves, turn the flowers into jelly and nibble on the tender shoots of the plant, which taste like snow peas.
Making a meal out of invasive species isn't to everyone's taste however. If you can't (or won't) eat them, you can hunt, drug, sniff, zap, infest, or adopt the creatures, as well as give them contraceptives.
