I have two. M'aiq, once spawned, will remain in that area until he's respawned elsewhere. So, if you want him out, you'll need to respawn him in another part of Skyrim. Find a random encounter spot where M'aiq is known to appear (e.g. the path leading from Whiterun to Riverwood alongside the river and behind Honningbrew Meadery), and keep revisiting that spot until M'aiq turns up.
If you just want him out of your house but don't mind him on your property, try inching him towards a door by getting in his face and making him back up. Once both you and he are near a door, engage in conversation with him, and quickly exit through the doorway as he's talking to you. He should follow you out.
