You just let lots of spiders gather in there, and have them fight one another, like a tiny arachnid thunderdome. It's a most entertaining way to spend an evening.
The downside of this is that you may end up with one super-tough spider, that can't be killed without the aid of explosives.
Wouldn't I also be a bit smelly from the lack of showers/baths?
(The last one I saw in there was mega huge, but my cat made short work of it.)
