Terrifying moment a pest controller finds huge huntsman spider and hundreds of her babies in Australia

It could be a scene in a horror film: you're trapped in a dark, confined space where hundreds of spiders are scrambling in all directions.

But it's all in a day's work for pest controller Noel Parminter, who stumbled upon a harrowing huntsman family in the roof of a Kholo home in Queensland, the Daily Mail reported.

Footage of the nasty surprise shows the mammoth mother spider keeping a close watch over her hatchlings as they clamber out of their nest.

The Queensland veteran said it was the biggest arachnid he had encountered in his 16-year-career, estimating she measured in at about 20cm.

"If spiders make you squeamish, don't press play ... you have been warned!" he wrote on Facebook.

But it seems many didn't heed his advice, with commenters vowing they would rather burn down their house than face the eight-legged intruders.

"There's no way. I'd just burn the place down. Now I'll have nightmares.

"Omg that makes me want to vomit!! That's like some seriously scary spider movie s**t!" wrote another.

The bite of a huntsman isn't dangerous to humans - it's their fearsome appearance, and knack for crawling out of car dashboards, that's the real concern.
