Mouse Trap

I bought mouse trap yesterday. There is one big mouse constantly coming in to our home every night. I am scared because it is very dirty. They are living in the drainage canals and come inside the house roaming around to look for food while we are asleep. I am scared because it is a carrier of so many kinds of micro organisms contaminating our kitchen, the other appliance and specially our kitchen utensils. These microorganisms are the cause of different diseases.
Before i 'll go to my bed tonight i will ready the trap with three heads of dried fish to attract him.
Ha! ha! ha! intelligent mouse! I will make it sure that this is your last night!!!!
