In my household, the Pioneer Rule is always in effect: if you don't work, you don't eat. Seriously. There is always some way to contribute.
In your op you say this person (or is it more than one?) was originally going to stay three weeks. If you explicitly agreed to three weeks, I'd say try to stick it out for that 21 days but make it clear that day 22 was not up for negotiation. Being asked to try, you've tried and it's isn't working for you. No harm, no foul, the situation just didn't work out. If there was never any specific timeline established, I would establish one. It is your right as one of the contributing members of the household. If you're feeling generous, 14 days should be sufficient.
On the other hand, if you're pissed off that your home has been infested by slacker/s, you might also consider pulling on your butt-kicking boots and putting them to work. That's what I would do. Honestly, if it were me, I would already be soaking in a hot tub working out the knots I had gotten in my legs by kicking his/her/their sorry ass/es up and down both sides of my street to make damn sure s/he understood that such triflin'-ass ways were not welcome in any part of my house, my life, my any-dam-thing! And then I would have a "frank and open" discussion with my lover on how these situations can best be avoided in the future. But maybe that's just me . . .
Nope, definitely NOT just you.
Years ago, when I was still with my boys' father, my brother and his family needed a place to stay. We had a trailer so we let them stay in it for a specified amount of time. The time came and went & they were still there. I finally had to tell him they had a week to find somewhere else to stay. He was NOT happy with me but I did what I needed to do for my own, and my family's, sanity and peace of mind!
Once my limits have been reached that's it. There is no more Miss Nice. The biotch comes out to play.
