One of the last things people want to discover in their home is a massive group of spiders in a forgotten crevice. Although we've often been told that spiders are good for a happy home, there's something about a whole army of them that makes that lesson very easy to forget.
I'll gladly say that I'm someone who actually likes spiders, but even I won't pretend that I'd be happy to discover a bunch of them wriggling out of a hole in the wall at once.
And yet, that's essentially what a conservation group in Australia had on their hands in a place they least expected to find them.
