You could try staying awake to spite the cricket. It might give up and go somewhere else.

Perhaps introduce it to a nice lady-cricket (outside the house of course) coz after all, he's only trying to find a mate.

Make your own personal noise to make the cricket jealous.

A while ago I read that the noise crickets make is designed (but not by something intelligent) to be particulary hard to track down to aviod predators ( and to confuse people trying to kill them with bugspray), perhaps it's not in the wall.

If it definately is, smash a hole in the wall or down. Then you can get the cricket.

Hope those ideas help.
