Watch Spider Crawl Across Homeowner's Kitchen Counter In Terrifying Footage

A homeowner suffered every arachnophobes worst nightmare after spotting a large spider crawling across his kitchen worktop on a security camera.

Simon Thompson, 60, from Happisburgh, Norfolk, in the U.K., caught sight of the arachnid on his Ring Indoor Cam at around 6:44 p.m. in the evening. In a further terrifying twist, the spider was only visible through the camera's night vision feature, with its origin still something of a mystery.

Bites from spiders are relatively uncommon in the U.K. However, the official guidance from the National Health Service (NHS) does warn that some native arachnids, such as the false widow spider, are capable of giving the unsuspecting victim a nasty bite.

While the bite itself can be painful and may result in some redness of the skin or swelling, in rare cases the reaction can be much worse. "Some spider bites can cause you to feel or be sick, sweating and dizziness," the NHS warns. "Bites can also become infected or cause a severe allergic reaction in rare cases."

The main advice to anyone experiencing severe or noticeable symptoms following a spider bite is to get medical help immediately.

While this course of action only applies to extreme cases, the sight of a spider can still be a source of concern for anyone with an aversion to arachnids.

Plenty watching the footage will fall into that category, with the American Psychological Association estimating as many as 10 million adults in the U.S. alone suffer from at least one kind of phobia.

But while the footage might set some off, Thompson appeared nonplussed. "When I first saw the footage, I was amazed at the clarity, even more so as it was taken at night," he said. "Obviously, the closeness of the spider makes it look enormous!"

Some of that might be down to the fact he and his family regularly come into contact with wildlife around their Norfolk home. "This is the first time we have caught anything like this on camera apart from various wildlife on the outdoor cameras, [such as] deer, birds, rabbits [and] squirrels etc," he explained.

It's not clear exactly what species of spider features on the video but Norfolk is home to a variety of arachnids. One of the most notable types found in the region is the Fen Raft Spider, which is thought to be among the U.K.'s largest.

Fen Raft Spiders can boast a legspan of up to 7 centimeters, are brown in color and are noticeable for having a beige colored stripe down either side of their body as well as speckled legs, according to the London Zoological Society.

Typically the size of your palm, they mostly occupy wetlands, where they trap insects, tadpoles and occasionally fish.
