Store valuables in your basement
We’d like to emphasize that hiding your stuff in freezers, inside of books, or in other creative places you saw on TV or movies won’t help you much. Burglars have seen those movies, too, and they usually check those places first. If you have a basement, consider storing your valuables down there.
Nobody wants to into basements. They’re dark, humid, and possibly infested with rats or other kinds of vermin. Plus, there are probably multiple hiding places down there, like old boxes and paint cans. Also, don’t booby trap your basement. Injuring the potential burglar might land you in jail.
