Here's another picture of the spider above. It's blurry because I was in the process of fleeing* after being startled when it suddenly jerked into action, perhaps annoyed at being documented.

As my wife sensibly says, "What do you think they'll do with you once they 'take you down'?" Keep me on tap to feed their bloodthirsty brood, of course.
Last night there was another 'big one', as she put it, who made an appearance after I'd turned in. My alternate theory is they want to

In place of a glass and a piece of cardboard we have a spider catcher, a mini-vacuum cleaner which can serve as a teleportation device to the outside world where they grow fat on ramblers and big enough that they can't fit back through the door. It can also be used as a sabre in case they're too hefty to be beamed up.
