The iguana population now numbers in the hundreds of thousands in the southern portion of Florida. The weather keeps the reptiles, who are native to South and Central America, from going any farther north than the I-4 corridor.

The most abundant lizard is the green iguana (pictured right on a Boca Raton hotel pool deck), which lives up to 22 years, grows up to 6 feet long and defecates about a pound of feces a day. One lizard population on the rise is the Nile Monitor, a relative of the Komodo dragon. Indigenous to Africa, the 7 1/2-foot-long, 22-pound reptile that looks like it came from the dinosaur days preys on baby crocodiles for food.

The biggest complaints about iguanas seemed to be their poop, which contains salmonella, and their love of decorative plants.

Some options for annoyed citizens? A "Super Soaker" filled with ice water, a tether ball attached to a rope and the "ever popular broom or mop." One local man also created and is selling a special "Iguana-Rid" spray. While euthanasia is an option for some, there are strict guidelines governing the method, Bill Kern Jr., a University of Florida associate professor of entomology and nematology, told the crowd.

"Whack them in the head, stun them and then decapitate them," he said. "Whack them in the head more than once and it's animal cruelty."

The harassment and euthanasia discourse elicited a question from an audience member: "Can you whack them with a machete?" a man asked, drawing roars of laughter from the crowd.
