It would be so cool to find the origins of these beliefs. Are you going to research into that? Many of the old wives tales I grew up with was used to instill discipline, like not leaving a drawer open because you will call death into the family if you do. Who will ever leave a drawer open after that?
Others that stays with you forever:
* A bee in the house before twelve means good luck, but bad luck after.
*You are supposed to invert a piece of clothiing at noon if you put it on the wrong way round in the morning.
*If you kill a frog it's going to rain.
*If you come home after midnight you should enter with your back so the ghosts think you are going out and don't follow you in (don't know what self respecting ghost will fall for that one, but we did it anyway).
In the book The Secret Life of Bees, the main characters stand-in mother tells her that "Bees only swarm before death." She says this because the girl is seeing a swarm of bees in her room every night.
Many of these superstitions, for all intensive purposes, no longer have any origin - there are many that were popularized by books or cinema. A good bet though is that many of them came about due to old beliefs about certain animals and insects, as well as due to books that became popular and then died out quickly.
