hello Gurpal, once they are in its near on impossible to get them out. try rat poison at the entrance and remove all water from your surroundings because once they have taken the bait it makes them very thirsty and they will come out to drink - if there is no water they will find it difficult to survive. also you can use high pitch sonic noise boxes, available on the internet. the pitch is very high which the humans cant hear but animals cant stand and move away. buy a few and place them around the house where you think they are. you could also get a big cat.
