I've managed to catch four of the bastards this afternoon. Not too far from my computer is an open box of saltines, with about half a package left inside of it. The mice make a lot of noise getting through the plastic, and the box is long and smooth enough that I've been able to turn it up-right and close it before they've been able to get out.

Right now, the four of them are running into the walls of an old cooler that I haven't used in years. I'm not sure what I'm going to do with them yet. If I caught the infestation early enough, and don't find very many more, I might take them to the country. If there are many more, I'm going to kill them mercilessly and place their heads on spikes as a warning to the others...

The house next door had some mice problems awhile ago. I'm guessing that mine were refugees.
