The number of false widow spiders is starting to soar across the UK, insect experts have warned.

The eight-legged creatures, related to the deadly black widow, are reproducing at a higher rate than in many years, it has been claimed.

Attacks have already been reported as pest controllers warn of their dangers, the daily star reports.

The recent heat has led to a surge and people said to be on the lookout for Britain’s only poisonous spider.

False widow spiders are breeding in the millions as hibernation ends and the thermometer soars – and their bite is a real punch.

Expert Clive Boase said: ‘The population of false widows in the UK is constantly growing.

“People don’t realize how mainstream they have become. They can survive both indoors and outdoors.

“They are generally shy creatures and don’t come out into the open – but they can crawl through curtains or perhaps clothing left on the floor.”

Joe Hildebrandt, from Conwy in North Wales, revealed his hand swelled up like a balloon after being bitten in his garden.

He said, “Spiders don’t scare me, but this one does.

“When I saw it on the floor it scared me a little like it had on my arm – and I know they won’t bite unless provoked.”

The British Arachnological Society says the bite of a false widow spider is similar to a wasp sting.

Experts say symptoms of seizures can include pain, swelling, nausea, tremors and altered blood pressure.

Michel Dugon, an expert from the National University of Ireland at Galway, said: “In addition to their medically significant venom, false noble widows are extremely competitive.

Two decades ago, this species was almost unknown in Ireland, the UK or mainland Europe.

“One thing is certain, however – this species is here to stay, and we must learn to live with it.”

Pest controller Rob Simpson urged people to keep homes tidy and vacuum regularly to keep critters at bay.
