Bear Grylls is de-wormed by his wife before she lets him back into family home following his latest wilderness show 

Bear Grylls has been forced to take a de-worming pill by his wife after his latest show in the wilderness.

Shara, 41, refused to let her explorer husband back into their houseboat on the River Thames until he had taken one of the family dog Mina's tablets.

Grylls revealed his wife told him: 'Eat this. I keep seeing clips of you doing various things on telly and I think you need to be de-wormed,' The Sun reported.

'It was even one of the dog ones as well,' the father of sons Jesse, 12, Marmaduke, nine, and Huckleberry, seven, complained.

Known for his expeditions across the globe, the 41-year-old's latest exploits have seen him spending months in the South African bush for the latest series of his Mission Survive series on ITV.

During the show, which he claims is among the most dangerous in the world, the adventurer - who is known for drinking his own urine in the wilderness - pushed contestants to the edge of their limits.

Celebrities including Neil Morrissey, Michelle Collins and Stuart Pearce were expected to find their own food in extreme conditions, undertake gruelling treks and even attempt a leopard crawl over a huge drop.

Last year, Grylls had the unique experience of taking Barack Obama on a trek around the glaciers in Alaska to promote public awareness of climate change.

The President and outdoors expert shared tea brewed from berries, ate bear-gnawed bloody salmon, talked about drinking urine.

Throughout filming snipers kept watch from the mountains and the official food taster looked on nervously as the leader of the free world ate Grylls' offerings.

Obama is the first sitting president of any nation to take part in Running Wild with Bear Grylls, following in the footsteps of celebrities like Ben Stiller, Kate Winslet and Zac Efron.

The former SAS soldier turned adventurer and survival specialist, said the idea for the TV episode came from the White House.

But Grylls has been accused of fraud in his previous shows and was criticised for The Island.

In the series participants had to 'fight for survival' using 'the hunter gatherer skills of our ancestors', according to Grylls.

But it later transpired producers had shipped in water and released extra pigs, iguanas and crocodiles for the contestants to eat and even left coconuts on the beach.

While in Born Survivor, a crew member revealed the Eton-educated explorer would often stay in hotels with internet and cooked breakfasts after the cameras stopped rolling.

In one episode when Grylls declared he was a 'real life Robinson Crusoe' stuck on a desert island, he was actually on an outlying part of the Hawaiian archipelago and retired to a motel at nightfall. 

Channel 4 launched an investigation into the claims,which said members of the public were misled by the show.
