It is the most dangerous spider to be living in the wild and breeding in britain, and its bite can put a fully grown man in hospital.
The species has been in the country for over 100 years after being introduced on a cargo of bananas from the canary islands.
But according to Stuart Hine, an insect expert at the Natural History Museum, it is spreading:
"There is no doubt in my mind that this is due to the milder winters caused by global warming,"
"Every year, the UK is breaking records for warm temperatures and it is these temperatures that are keeping the spiders alive. It used to be only a handful of spiders would be able to survive the cold weather so the numbers were always kept down. But now they are all surviving the winter and are crawling out of hibernation earlier to mate."
"The numbers have just rocketed into the hundreds of thousands. They can hide in gardening gloves and will bite when you put your hand in. We would urge gardeners to be on their guard in the future."
quoted from gmtv:
A bite from the false black widow delivers enough poison to cause severe pain and inflammation.
Last year market trader Jason Fricker, 34, from Dorchester, Dorset, spent three days in hospital after one bit him on the chest. An entry on the Natural History Museum's website said a bite from the spider at first caused a burning sensation. It then 'increased in intensity, like being scalded, stabbing pains spread first to armpit then down right arm'.
The entry concluded: 'Also flu-like symptoms, aches, sweats, fatigue, perspiring, cold and shaky. Face and right arm went purplish and slightly puffy. Felt unwell for three days.' Another victim reported that the bite lasted for a similar time before becoming infected.
One study found that the pain was far more severe than that from a wasp or bee sting. Mr Hine added: 'Normally an antihistamine cream will take the pain away but, depending on the amount of venom injected, a doctor may need to be seen.'
The species - only the female of which bites - had been considered native to Dorset but has spread as far as East Anglia. It usually lives on walls, fences and tree bark.
"Steatoda Nobilis' is the the most venomous of the 12 biting spiders in Britain.
Only the females bite and they live for around four years while males die younger.
Despite their reputation, they eat only woodlice and smaller spiders.
They have very poor eyesight and depend mostly on vibrations to find their way around.
They grow to up to half an inch long and are increasingly found in garden sheds and outbuildings
this is worrying news for me as i am an arachnophobiac as it is, and ive always told myself they cant do me any harm to try and overcome it, but now i cant be so sure!
So gardeners be careful this summer! and anyone else who is out and about in the UK.
P.s. sorry to kind of leave out anyone who isnt in the UK
