Bee stings are usually not hard to remove. Take a rigid card (for example a credit card,) and gently scrape along the skin opposite to the direction it entered until it comes out. Don't try to take it out with tweezers because you may crack the stinger causing more "poison" to get into the bloodstream and you may leave fragments of the stinger in the skin. Generally, the "poison" is not actually poisonous unless the person is allergic to bee stings.
There is a superstition of if a bee is in the home and stings it was due to the person swearing in front of the bee. This was believed because bees were considered to be divine messengers.
