A horrified family have come up against a very stubborn colony of spiders which appear to have laid claim to their backyard.

Denise and Sean Torkington from Hervey Bay in Queensland were shocked to discover that what they originally thought was a patch of dew beneath their children's trampoline, was actually a gigantic cobweb.

'We thought it was dew to start with from the kitchen window but when we saw it again in the afternoon we needed a closer look and realised it was a spider's web,' Mrs Torkington said.

Having lived at their Piabla property for six years, the 'strange phenomenon' was the first they'd ever seen.

Even after Mr Torkington tried to remove the determined arachnids himself, they came back with startling force.

'My husband kicked it away hoping they would move on but they rebuilt it overnight and it was grown everyday since.'

Mrs Torkington turned to a Facebook gardening group on Tuesday night for advice, but left group members stumped and sarcastically encouraging the family to 'burn everything and run'.

She said the neighbours were completely foreign to the freakish occurrence as well.

An arachnophobe herself, Mrs Torkington was terrified to discover what she thought to be baby spiders and eggs within the web.

'This is the thing nightmares are made of,' she said.

The family are enlisting a professional pest removal service to hopefully keep the impostors away from their yard permanently.

'I'm hoping they don't come back that would be a nightmare.'
