how do i set a booby trap to find out if someone has been in my house?
i gave my neibors my keys and i think they made coppies and have been coming in my house while im not here. things have gone missing, i want to know how i can set a trap that will enable me to be certain that they have been in the house, and that its not really just me loosing things. i want the traps to be set up in a way that i will know for a fact someone has been in my house, i have one idea already i have ties a lot of my hairs together and tapes them accross the hallway and i will see if when i get back home it is busted. please help me with this, i dont want to go to the owner of the building, or to the athoriteis with out knowing for a fact, and i am unable to get a video camera to record while i am gone.
