This is the terrifying moment a British man discovered a family of four false widow spiders living in his kitchen - and managed to successfully trap them all.

The unnamed arachnophobe from High Wycombe, Buckinghamshire, posted a video which shows four of Britain's most venomous spiders scuttling around in the glass jars he used to capture them.

False widows are named for their physical resemblance to the deadly black widow spider, which is not found in the UK.

The man explained in the video that he discovered all four of the arachnids lurking in his kitchen, and because of their varying sizes he concluded they were part of a family.

He said: 'I have to be very careful with these spiders, this one's quite a big one - I hope he doesn't run off anywhere!

'To be careful I've got my glove on at the moment. If you see one of these in your house you have to be very careful.

'As you can see its a very horrible looking creature. I've found four today.'

The big one: This false widow spider was the largest of the four and was held in its own glass jar

Millions of false widows, Britain's most venomous spider, have been found across the UK and the population is believed to be growing

A one point he took the jar off the largest spider in order to show it off to the camera, but when it made a quick bid for freedom he scrambled to re-capture it, exclaiming: 'Oh god, Jesus Christ, phew, oh I won't be letting that out again!'

Breathing heavily, he adds: 'I wouldn't like that crawling over me at night.'

He explained he planned to release all four spiders back into the wilds of his back garden.

False widow spiders can grow up to 3cm across, including the legs, and are distinguished by their shiny, black, bulbous bodies and markings which look like a skull on their abdomens.

False widow bites are generally not life-threatening and have been compared to the pain of bee and wasp stings.
