The popular ITV show, helmed by Ant McPartlin and Declan Donnelly, is set to return to the small screen on November 19, but just days before the celebrities pitch up in the Australian jungle the shows bosses have found two huge reptiles, one reaching over five foot, and they predict the camp will be invaded by swarms of slithering animals during this series.

The two carpet pythons, which are also known as Morelia Spilota, are common in Australia, and they kill their prey by constriction.

Although the creatures are not poisonous and would not kill a human being, they have been known to devour small dogs and cats.

And it is believed the "unseasonably cold weather" is the reason for the snake infestation.

Speaking about the discovery to The Mirror Online, a source said: "The unseasonably cold weather has brought the snakes out as they try and find somewhere warm. This will be an ongoing problem this year, which is not good news for the celebrities."

However, experts and the medical team will be nearby and "on the lookout" for any dangerous species that could prove "fatal" to anyone competing on the programme.

The show insider continued: "Medic Bob and the team will have to be on the lookout for anything dangerous as a snakebite can easily prove fatal if not treated quickly."

But snakes are not all the contestants will have to worry about as the camp has also been invaded by killer spiders.

Dr Robert Raven previously said: "In the past we've had early rain and nothing. Just really dry summers. But this summer, the rain is allowing the whole system to crank up again. People should check everywhere.

"If you pick up your towel, the next thing you know you could have a huntsman on your face. A lot of spiders are pretty harmless, but redbacks are of particular concern."
