There's an old saying to do with black holes..."A black hole has no hair", meaning theirs nothing a black hole has or radiates which can be easily detectable, apart from it's gravity.

However, a black hole not only has hair (Hawking....Hawking Radiation), but they do evaporate. Only for a stellar mass hole it takes on the order of 10^66 years to evaporate to the stage where it becomes unstable and explodes with the force of a billion H bombs
