I don’t know? Last time I had that trouble I ended up dragging him by his legs out of my apartment.

I might try the I want to take a bath now. Or do you want to go for a quick walk with me?

I usually tell my guests before they arrive that I need to do something soon, and only have a limited time.

Change into your pyjamas.
Start brooming the floor.

If they don’t get hints, just say you have to kick them out because you need to get ready for an appointment (could be a zoom with your family if they have the chutzpah to ask you what the appointment is). Or, if it’s late, just say it’s past your bedtime and you need to get up in the morning, or simply that you are getting tired.

My brother falls asleep on the couch – but he does that if you’re a guest in his house or he’s a guest in your house!

Some very good tips here. https://www.youtube.com/watch?v=RBj4iUeh5Qc

You tell them flat out. “You gotta go now”. We very rarely have guests we want to get rid of. Such folks usually don’t get in to begin with. And once you’re in, we don’t usually care if you stay. Whoever falls asleep first gets a blanket tossed over them. The wife always turns in early, but is prone to pass out in her big recliner after particularly busy days. Our guests and relatives know the drill.

Just say, “I have a lot to do to get ready for tomorrow and I’m too tired to do it all…....” This works every time.

“I think there’s going to be a black-out.”

Stands up. Goes down the basement. Turns main power off.

I yawn, stretch, and start looking restless – look around, seem distracted, massage my neck, etc. Anything to appear tired.

Straightforwardly but tactfully: “Well, it’s been great seeing you…”

(Pause to let them say “Yeah, I’ve got to be going.”)

Continue if necessary: ”...but it’s about time for me to say good-night.”

If they don’t take the hint, that means you can worry less about tact.

I open my mouth and speak. Time to go.

My Father would just tell people, “Alright, Get the hell out of here. I’ve got things to do.”

I pick them up by their belt and shirt collar and give them the bum’s rush.
