How not to kill the mouse in my house? I live with my mother in her house. There have been a mouse for a few months, living in the ceiling of my bedroom, and since a few weeks, it has been a nuisance for it scratches something, day and night, to the point of preventing me to sleep, even when wearing ear plugs. 

The mouse does not seem to understand that it is not alone in the house and that it causes distress. I remember that There were mice long before and the rat poison was successful, until another mouse set in. They always find their way in, and always end up breeding and making a noisy mess.

I cannot access the ''thermal material''  which is between the ceiling of my bedroom and the  attic, because the attic has been covered up by some thermal blanket to better protect the house  thermally.

I do not wish to kill the mouse with some  rat poison per se. but I  also fear that the mouse could chew some wires, electrical and telephonic, which pass above the ceiling and causing damage to the house. I also fear that the mouse breeds leading to even more mice, especially if I end up killing them.

There are cats in the neighbourhood, and it is not clear to whom they belong, but they clearly did not catch the mouse thus far. I cannot get a cat myself, since there is no place and no means to sustain having a cat. I do not know the path to the garden that the mouse takes to leave the house, because there are plants and small trees preventing me to watch the ground and weed.

Is there another solution than killing it in disposing some rat poison, in order to stop the noises and be assured that the house will not be damaged ?
"Without wisdom, effort, restraint of the senses, without giving up everything, I see no well-being for beings."
  
  -- The Buddha (SN 2.17)


You can't have your cake and eat it too, unfortunately. The truth is the truth whether it is convenient or not. In this case, there are some fairly important truths that you have to consider when trying to decide what to do.

First is the truth that being a nuisance is a far lesser evil than murder in cold-blood... the mouse has the moral higher ground over the mouse-trapper. 

Second is the truth that you don't want to be murdered yourself; knowing this, how can you contemplate it for a fellow being?


  All tremble at violence; life is dear to all. 
  Putting oneself in the place of another, 
  one should not kill nor cause another to kill.
  
  -- The Buddha (Dhp. 130)


Third is the truth that killing makes you a killer; it changes the direction of your life in a significant way that will have potentially far-reaching consequences, far beyond feeling a little guilty for a little while. There are karmically significant mind-states involved in killing that may not be evident to you until you actually kill. Once you've begun to kill, you start to desensitize yourself to killing; it gets easier and easier, and your mind becomes further and further sullied. 

Fourth is the truth that the reason you can't sleep has little to do with the mouse and much to do with your own state of mind. In fact, lack of sleep itself isn't really the problem either; if your mind is clear, you can stay awake all night and not suffer harmful consequences.

My advice is first, to come to terms with your mind's reaction to noise that keeps you from finding peace; reminding yourself "hearing, hearing" is a good way to keep yourself objective and alert.


  “In that case, Bāhiya, you should train yourself thus:
  In what is seen there will be only what is seen,
  in what is heard there will be only what is heard,
  in what is sensed there will be only what is sensed,
  in what is cognized there will be only what is cognized.
  In this way, Bāhiya, you should train yourself.
  
  And since for you, Bāhiya, in what is seen there will be only what is seen,
  in what is heard there will be only what is heard,
  in what is sensed there will be only what is sensed,
  in what is cognized there will be only what is cognized,
  therefore, Bāhiya, you will not come to be because that;
  and since, Bāhiya, you will not come to be because that, therefore, Bāhiya, you will not be in regards to that;
  and since, Bāhiya, you will not be in regards to that, therefore, Bāhiya, you
  will not be here or hereafter or in between the two - just this is the end of suffering.”
  
  -- The Buddha (Ud. 10)


Second, consider whether it is your duty as a householder to take care of the mouse, or whether you can just as well leave it be. Unless it is destroying insulation or wiring, I don't think there is a compelling reason to remove a mouse; a rat, maybe... Either way, there are many ways of relocating a mouse humanly.

In regards to cats, if you in any way encourage a cat to catch and kill a mouse, well, it's not categorically different from killing it yourself...
