If a bee enters your home, it's a sign that you will soon have a visitor. If you kill the bee, you will have bad luck, or the visitor will be unpleasant.
Bees have often been regarded as wise and even holy insects, having foreknowledge as well as knowledge of many secret matters.. If a bee flies into the house it is a sign of great good luck, or of the arrival of a stranger; however, the luck will only hold if the bee is allowed to either stay or to fly out of the house of its own accord. A bee landing on someone's hand is believed to foretell money to come, while if the bee settles on someone's head it means that person will rise to greatness. They were once considered to deliberately sting those who swore in front of them, and also to attack an adulterer or unchaste person; it was once held to be a sure sign that a girl was a virgin if she could walk through a swarm of bees without being stung.
