The ITV show has defended its use of bugs, saying all the insects used during the programme are "non-invasive species".
"The matter is being investigated by Rural Crime Team officers", a North Wales Police spokesperson said.
The Guardian newspaper reports that the ITV programme is under police investigation after complaints that cockroaches, maggots, spiders and worms could threaten Welsh wildlife if they have escaped.
The report said that Natural Resources Wales - the authority which gives out licenses for release of species in the wild - did not receive any request from ITV.

He told BBC Breakfast the Welsh Government had "worked carefully" with the production company to make sure that all the rules were being observed and they "would be concerned about non-native species being released".
"Viewers will have seen the stories from Denmark recently about mink and coronavirus crossing species".
It will be a breach of the Wildlife and Countryside Act if the non-native creatures have been released by ITV without a license.
The programme's spokesman added: "All of the insects used on I'm A Celebrity are non-invasive species".
According to them, they are released in an open area and are collected immediately after shooting.
He said: "The bugs are United Kingdom bred and are commercially purchased in the United Kingdom for birds and exotic animal feed for pets and zoo keepers in normal circumstances".
Welsh naturalist and BBC Springwatch presenter Iolo Williams raised questions over the programme's use of the creatures.
"Our insects have been donated to local wildlife sanctuaries, trusts and zoos for their exotic animal and bird feed after filming".
