I'm A Celebrity… Get Me Out Of Here! is reportedly under investigation over fears the non-native species used in the challenges could escape.
Insects such as cockroaches, maggots, spiders and worms, some of which are not native to Wales, have featured in challenges, which see the cast of celebrity campmates covered in bucket-loads of bugs.
This year, the show is being hosted on the grounds of Gwrych Castle, near the town of Abergele, with a sprawling 250-acre estate surrounding the fortress.
North Wales police are looking into complaints these Aussie creatures could pose a threat to the Welsh landscape, according to The Guardian.
When contacted by Daily Star, an I'm A Celebrity spokesperson confirmed the species used in the show were non-invasive and said there was no possibility the insects could escape into the local habitat.
Their statement read: "All of the insects used on I'm A Celebrity are non-invasive species.
"They are only ever released in a contained area and collected immediately after filming.
"The bugs are UK bred and are commercially purchased in the UK for birds and exotic animal feed for pets and zoo keepers in normal circumstances.
"Our insects have been donated to local wildlife sanctuaries, trusts and zoos for their exotic animal and bird feed after filming."
The concerns initially came to light when TV presenter and naturalist Iolo Williams made a complaint while watching the show, pointing out the species that were being used in the challenges were not native to North Wales.
He told The Guardian: "I'm not sure which species they're releasing, but I can tell you they're not native.
"We don't have those cockroaches here in the UK and we certainly don't have them in north Wales."
The nature-expert added: "There are going to be cockroaches in every nook and cranny along their bodies, you're going to tell me that every single one of those is found immediately? Of course it's not."
I'm A Celebrity… Get Me Out Of Here! continues tonight at 9pm on ITV.
