But it would take a longer run of cold days to do kill the invasive nuisance, which eat landscaping, dig burrows that undermine foundations and produce droppings that can carry salmonella bacteria.
That happened in January 2010 when South Florida experienced nearly two weeks where the temperatures reached into the 30- to 40-degree range.
Not only was a substantial portion of the iguana population killed, Burmese pythons also died.
“Many pythons were reported dead, floating in the Everglades,” a statement from FWC said. “Although the iguana or python population may have some mortality occur, the length of time of cold weather may not be enough during this cold snap to make a significant difference.”
Be forewarned that a cold-paralyzed iguana, or a knight anole as seen in the photo above, can become active again when temperatures begin to warm. That means it’s probably not a good idea to bring them inside.
