How to evict a roommate that is not on the lease?

Question Details:

I need to get rid of my roommate. I never put him on the lease and he hasn't paid a dime in the 5 months I've allowed him to stay with me. I could totally get evicted for having a roommate not on my lease but I live in a ghetto trailer park, so the landlords are pretty lax. I'm hoping to get him out ASAP, as in sooner than 30 days. My general hope is that he has absolutely no right to be here and I can tell him to get out at my leisure and I'd be in the right. Important Notice
