They may enjoy it more than you’d like to think about.
@ the OP: The thief isn’t necessarily someone who lives in your building. People invite guests into apartment buildings all the time, and even if you are uninvited it’s not that hard to get into most apartment buildings. If you are coming up to the door at the same time as someone else is entering or leaving, just about anyone will hold the door open for you instead of closing it in your face and forcing you to prove you are authorized to access the premises.
Something liquid, foul smelling and or very staining might be a treat too. Preferably non toxic.

A dye pack could be easily made from a ziplock baggie and secured in such a way to pop open the baggie when box is opened. A little experimenting with water and duct tape could make for a lovely bit of low grade minor terrorism as well as possible identification of the theif.
Did you ever hear of Bee-Go? Of course, that’s kind of a nuclear option, as it may result in the evacuation of the entire apartment building. The stuff is FOUL. :eek:
It’s a shame you can’t trust your neighbors. I lived on the top floor of an apartment building during my senior year in college. The foyer was shared by three rooms total, which housed somewhere around ten people. Packages were delivered and sat in an area where literally anyone could take them if they wanted. Fortunately, my flatmates were all trustworthy and left them be. I ordered many hundreds of dollars worth of books and clothes and never had a problem. Sorry this wasn’t the case for you and fuck the thief in the arse!
