Many have taken to social media to post their snaps of the creepy crawlies
One dad, Nick Oldham, took a snap of a huge spider, with a seven-inch leg span in the spare bedroom of his home.
There are fears the spiders are looking for a spot to lay hundreds of eggs which could see their homes overrun with spiders.
Mr Oldham said he his was horrorfied when he found a spider with a seven inch legspan lurking in the corner of a room.
He said: “These things are seriously BIG!! Imagine the horror on my son’s face when the spotted this big boy on his wall.”
The Giant House Spiders, whose bite is similar to a bee sting can even pierce the skin.
Arachnologist Chris said: “Giant house spiders are the Golden Retrievers of the spider world, because they are much less shy than their relatives.”
Some have warned the some of the larger specimens could potentially break through human skin although most of the spiders do not have fangs long enough to pierce skin.
Kris Clare said his wife was chased from room to room by a giant spider.
Macclesfield’s Bethan Tuckman said she was given a fright when she saw a four inch wide spider and she got an even bigger fright when she realised there were at least three of them in the house.
The spiders, who prefer dark spaces and crevices, are among the largest spiders in Europe.
The male spiders are often said to sample the silk that females leave behind, tasting it to see if it is from the same species, making it a good idea to dust and keep your house clean in a bid to prevent entering in the first place.
