Creepy crawlies, in the form of an infestation by spiders called false black widows, has forced a school in Britain to close a week before Halloween.
The Dean Academy, a secondary school in southwest England's Gloucestershire, said it was closing to get rid of the false widow spiders. The spiders are commonly mistaken for their relative, the black widow spider, whose bite can be fatal.
The school said no one has been bitten by the spider but local health authorities have advised it to close for the day to deal with the infestation, according to The Associated Press.

Experts say the Steodata nobilis, a species of the false widow, are becoming more common in the U.K. and are the most dangerous of the 12 species of biting spiders known in Britain.
But they stress that spider bites are rare in Britain, and in most cases the symptoms are mild. The spider's bite may sting, swell up or cause discomfort like a wasp sting, but has not been known to cause deaths.
"They're not aggressive spiders, they don't seek out humans," said David Lalloo, a professor at the Liverpool School of Tropical Medicine.
