DATE: August 17, 1989

ARCHIVAL (NBC NIGHTLY NEWS, 8-17-89):TOM BROKAW: They have a lot to talk about tonight in a Fort Lauderdale, Florida neighborhood. This was the day of the snake.

NARRATION: It was the snake that made national news 20-feet, 250 pounds and somebodys pet. But these massive snakes imported from Asia are more than a backyard nuisance.

ARCHIVAL (ABC, 7-17-09):NEWS REPORT: Twenty years ago there were no pythons or boa constrictors in the Florida Everglades. Today they seem to own the place.

ARCHIVAL (NATIONAL PARK SERVICE):WOMAN: Theres one up there.MAN: OK Yeah, I think we got one.

NARRATION: Theyre multiplying unchecked in the wilds of Florida.

ARCHIVAL (CNN, 4-21-09):NEWS REPORT: The pythons are expanding outwards in all directions.

ARCHIVAL (NBC, 02-04-09):ALISON HIGGINS (THE NATURE CONSERVANCY): This isnt the case of a let loose gold fish. This is something that can grow up to 20 feet and will eat anything in its sight.

ARCHIVAL (WPTV Ch. 5, 10-7-13):NEWS REPORT: Add another invader tonight to the list

NARRATION: Thousands of foreign pets are now ranging free in our midst.

ARCHIVAL (CNN, 10-12-09):NEWS REPORT: This place has become the Ellis Island of exotic species.

NARRATION: How did this happen? And how afraid should we really be?


ARCHIVAL (CBS LOCAL 12, 8-10-14):NEWS REPORT: This is a 12-foot long Burmese python caught by a Port Saint Lucie police sergeant in the middle of a neighborhood.

NARRATION: Encounters with wayward snakes once pets in someones home have become a regular feature on the news in reptile-loving Florida today.

ARCHIVAL (CBS LOCAL 12, 8-10-14):WOMAN: Oh my god. Thats on our street?REPORTER: Yes, yes it was.

NARRATION: More than two-million constrictor snakes pythons, boas and anacondas have been imported into the U.S. since the 1970s. Non-venomous but still fearsome, they kill their prey by strangling it, then eating it whole.

ARCHIVAL:Brittany Spears with a python singing at the 2001 Video Music Awards

NARRATION: Despite all that, the Burmese python, bred in a rainbow of colors, caught on with rock stars and regular folks.

BRIAN BARCZYK (REPTILE BREEDER, OWNER, BHB REPTILES): It used to kind of be the biker, long-haired, tattooed, you know, rebellious guy; now it can be a lawyer, a doctor. Really, the person next door could be keeping reptiles.

NARRATION: And often the person next door doesnt understand what theyve gotten into.

ARCHIVAL (NBC, 1-22-05):MIKE BERRERA (SNAKE IMPORTER): They buy them, you know, 12, 14 inches long, but then three or four years later they realize, you know, its a seven, eight foot snake, and they cant take care of it anymore.

NARRATION: Snakes roaming neighborhoods are one thing. But how did they end up 80 miles from Miami, in a remote region of Everglades National Park?

Beginning in the pre-Instagram 1980s, park visitors filled out cards to report sightings of snakes that were bigger than anything theyd seen before.

WALTER MESHAKA (CURATOR, EVERGLADES NATIONAL PARK 1995-2000): One time, I got a call from Royal Palm Hammock. And it was about an 11-footer, a female, didnt have a mark on her. And when I opened her up she was just full of fat, no parasites, no nothing. This was somebodys pet, clearly.

NARRATION: A pet most likely dumped out of the trunk of someones car.

ARCHIVAL (ABC, 7-19-09):NEWS REPORT: The problem isnt just pets. Hurricane Andrew destroyed snake hatcheries in the Miami area sending hundreds of baby snakes into the Everglades.

NARRATION: By 2000, Meshaka had published a study warning that Burmese pythons were reproducing in the southern end of the park.

WALTER MESHAKA: At the park it was not met with a sense of urgency that I felt it warranted. It is, in a way, a ticking time bomb. Will it be relatively localized? Will it explode, which, lo and behold, it did.

NARRATION: In the four years after Meshakas warning, python captures around the park went from 2 a year to 70. Park officials were caught behind the curve.

SKIP SNOW (WILDLIFE BIOLOGIST, EVERGLADES NATIONAL PARK, 1988-2013): We couldnt go to the Home Depot and buy a can of Snake-Be-Gone and just figure out what the-what the right dosage was to kill it. We didnt have those tools. Those tools werent there.

NARRATION: At the state level, Florida Fish and Wildlife officials hesitated to ban the sale of pythons, a move that would hurt the states $100-million reptile industry, hoping the snakes might die off on their own.

KRISTINA SERBESOFF-KING (ENVIRONMENTAL SCIENTIST, STATE OF FLORIDA 2001-2004; THE NATURE CONSERVANCY): We keep saying, Well, lets just make sure we get this right, you know? We dont want to ruffle any feathers. Lets make sure we really know that this is gonna to be a problem before we go and really impact somebodys livelihood. Were we taking it seriously? I wouldmy personalno.


NARRATION: What forced the issue onto everyones radar were clashes between pythons and the parks top predator, the alligator.

ARCHIVAL (NBC, 1-22-05):NEWS REPORT: After a 30-hour exhaustive battle, a draw.

ARCHIVAL (ABC, 08-11-06):NEWS REPORT: What youre looking at is a 13-foot python that ate an entire six-foot alligator, before bursting.

SKIP SNOW: That was the sort of the very first, very public display of these two rather large reptiles and kind of a turning point for-for both management as well as the media, I think, to pay attention.

NARRATION: And pay attention they did.

ARCHIVAL (NATIONAL GEOGRAPHIC TV, PYTHON WARS, 2-09-10):An alien species is invading the swampland of America.

NARRATION: As python captures soared to 367 in one year, so did media speculation about how big and scary the problem was.

ARCHIVAL (CBS, EARLY SHOW, 7-27-09):HARRY SMITH: Snakes are eating Florida.

ARCHIVAL (FOX, 01-14-13):SHEPARD SMITH: 150,000ARCHIVAL (NBC 6 LOCAL, 01-17-12):NEWS REPORT: 183,000

ARCHIVAL (WPLG CHANNEL 10, 01-17-12):NEWS REPORT: Over 200,000

ARCHIVAL (CNN, 4-21-09):ANDERSON COOPER: On the loose, traveling faster than you might think.

ARCHIVAL (NBC, 2-4-09):BRIAN WILLIAMS: A clear and present danger to people.

SKIP SNOW: Invariably, what would come out would be Big Snake. Be Afraid.

NARRATION: Adding to the sense of panic, a tragedy in 2009.

ARCHIVAL: (911 CALL, 7-1-09):OPERATOR: 911 – Do you need police?MAN: Our snake, we have a Burmese python, and shes about 12-foot long. She got out of the cage last night and got into the babys crib and strangled her to death.

ARCHIVAL (CBS, 7-03-09):NEWS REPORT: The autopsy report revealed the snake had in fact strangled two-year old Shianna Hare and may have tried to eat her.

NEW NARRATION: There have been 10 Americans strangled by constrictors since 1990 all victims in homes where snakes were kept as pets. Pythons have never attacked a tourist in the Everglades, but that didnt stop park visitors from being spooked.

ARCHIVAL (CNN 2-7-2012):TOURIST: I was afraid that thered be snakes everywhere, pythons and everything.

NARRATION: The real danger, park biologists argued, was not to humans, but to wildlife. With few natural predators to keep them in check, pythons were eating their way through the ecosystem, devastating populations of native birds and mammals, including a 76-pound deer.

SKIP SNOW: We know very little about them in their native habitat. So it makes it that much harder when they become an invasive species.

NARRATION: With their $10 billion effort to restore the Everglades under threat, federal and state agencies began spending a million dollars a year on python control.

ARCHIVAL (NBC, 01-22-05):WOMAN: Find it, Pete! Find it, find it, find it.

NARRATION: Enlisting a python-sniffing dog


NARRATION: Implanting transmitters in so-called Judas snakes to lead scientists to mating areas.


NARRATION: And setting traps. But the efforts barely made a dent. The snakes set new records for length and for eggs, 79 in one female.

WOMAN (AT REPTILE SHOW): Ready 1, 2, 3 smile.

NEW NARRATION: With Florida still allowing the sale of pythons as pets, the federal government in 2008 began considering a ban on imports of Burmese pythons and 8 other giant snakes. The reptile industry argued it would kill jobs in their $2-billion national industry.

ARCHIVAL (HOUSE COMMITTEE ON OVERSIGHT, 9-13-11 ):DAVID BARKER (REPTILE BREEDER): It will destroy American businesses and it will damage hundreds of thousands of people economically.

BRIAN BARCZYK: Theres no second amendment that says I can keep a python. But you take the Burmese Python away, the next thing you know youre taking a Leopard Gecko away and then maybe your dog or cat. You know, where does it stop?

ARCHIVAL (NBC 6 LOCAL, 01-17-12):KEN SALAZAR (FORMER U.S. SECRETARY OF THE INTERIOR): The action were taking today is a milestone for us in the protection of the Everglades.

NARRATION: After years of debate, while pythons expanded their range, the government in 2012 banned imports of the Burmese python, and ultimately seven other giant snakes. One newspaper expressed skepticism, saying Its closing the reptile cage after the snakes have already slithered out.


NARRATION: But pythons are not the only escaped or released pets that have become a public menace.

ARCHIVAL (CBS, 08-25-09):NEWS REPORT: Scientists are tracking an exotic invader, a small fish that has become one of the biggest bullies in the Atlantic Ocean.

NARRATION: Venomous lionfish, imported from Asia for aquariums, are now preying on native fish from Florida to Rhode Island.

ARCHIVAL (CBS LOCAL NY, 09-16-13):NEWS REPORT: Theyve blown up transformers, building massive nests on power lines.

NARRATION: Exotic birds from South America are causing headaches for power companies. And Floridas latest pet gone wild

ARCHIVAL (LOCAL 10, 03-05-14):NEWS REPORT: Its a cold-blooded killer eating its way through the Everglades.

NARRATION: A four-foot lizard with a nasty bite the Argentine Tegu.

FRANK MAZZOTTI (PROFESSOR OF WILDLIFE ECOLOGY, UNIVERSITY OF FLORIDA): There is nothing similar to this lizard in Florida, so when they get to a place like this, its kind of like walking into an untouched banquet table.

NARRATION: Tegus are eating the eggs of native birds and reptiles. Scientists are trying to contain it through trapping, but the lizard is already reproducing in three counties and spreading.

FRANK MAZZOTTI: To the west of us where tegus are heading towards rapidly, is one of the largest nesting areas for the threatened American Crocodile. A species that we brought back from the brink of extinction. Now may be threatened again by an invasive species.

NARRATION: In Florida, where there are now more non-native lizards than native ones, officials say stopping the tegu is a top priority. And yet tegus are still for sale as pets, virtually guaranteeing more releases or escapes into the wild.

FRANK MAZZOTTI: I think overall, the problem that were having is that we as human beings do not react until weve demonstrated theres a real problem. When you get to the point where you know you have trouble, then its too late to fix it.

ARCHIVAL (ABC, 01-13-13):REPORTER: What do you guys think your chances are of finding a python?HUNTER: Good. Oh, real good. Yeah.

NEW NARRATION: During a public bounty hunt in the Everglades in 2013, hunters bagged a disappointing 68 snakes, out of the 100,000 estimated to be there. Now the hunt, along with the dogs and transmitters, has been discontinued. After spending 10 years and more than $6-million fighting the python wars, the snakes appear to be winning.

SKIP SNOW: We dont know what to bring to the battle, right? You know, we really-we really dont yet have all that figured out.

NARRATION: Battling invasive animals, including those that arrive by way of the pet trade, costs taxpayers an estimated $50 Billion a year.

KRISTINA SERBESOFF-KING: We really should have a proactive approach and we still dont. Nobodys screening all the non-native wildlife thats being imported into the United States, to say which one is going to be the next bad actor. I mean, that-that right there just-just floors me.

WALTER MESHAKA: Maybe the way to put it is that the lesson learned is that no ones learned their lesson. Hows that for an awful lesson learned?
