This frightening photograph shows a clutter of Huntsman spiders crawling out of a wall socket near a homeowner's bed.
The man saw the little arachnids scurry up and around the wall of his home after they entered out of the crevices of the plug.
These freshly-hatched Huntsmans can grow to the size of a human hand.
Writing on social media, people shared their horror. One person said: "Sounds chilling."
Another posted: "That's the stuff of nightmares to me."
A third stated: "I shuddered looking at the photo."
The image was taken this week at an address in New South Wales' Central Coast in Australia, home to species because it likes the warm climate.
Scott Johnson, the moderator for the Australian Spider Identification online page, insists an army of arachnids like this is a godsend for any house.
"When they emerge, they'll only be around for a week and a half for the most before they disperse," the expert told Yahoo News Australia.
"They are great pest controllers, they'll eat all the mozzies and cockroaches... some people call them 'wall puppies'.
"Spiders like a dry environment for their egg sac ... they'll look for a nice dry spot, hopefully out of the way, and they usually end up inside away from the weather."
It takes an egg sac full of little spiders 30 to 60 days to hatch but can take longer in the winter months.
About 60 to 100 spiders can hatch at the same time.
Aussie Huntsmans belong to the Family Sparassidae and are famed as being the hairy so-called 'tarantulas' on house walls that terrify people by scuttling out from behind curtains.
Many huntsman spiders have rather flattened bodies adapted for living in narrow spaces under loose bark or rock crevices.
