Er....a 'i metre long gecko' is either a monitor lizard or a baby crocodile,😀

It was likely some sort of lizard. It was huge. And it hated the insect spray I liberally doused it with. It sort of passed out. I then removed it from our bedroom ceiling eve, where it was making a real nuisance of itself. 

i had the same problem a few years ago in a rental house. this is how i solved it:

near the spot where the gecko was hiding in the ceiling, there was a terrace with a built-in lamp. i removed the lamp and closed the opening at first. when it got dark, i opened it again and set up a bright light outside. the light attracted insects, and the gecko hunts insects. around midnight, i closed the opening again. i repeated this process for several days until the gecko stopped returning to the ceiling. maybe this method is worth a try for you too. good luck!
