Invader!!

You know that post, way back in my first months here in El Paso, the one about the mosquito in my room? Well, tonight I saw a cockroach skittering into the corner of my room. A cockroach!

If it were only a mouse, I've trapped those before, I'd know what to do. But what do I do with a cockroach? At the moment it is hiding under the mattress, so for tonight I'll just have to pretend it doesn't exist and try to sleep.

So what do I do to get rid of a roach? How can I trap it? Any ideas?
