Hit the jar on your palm to knock the bees to the bottom for a moment. Quickly open the lid, insert empty toilet paper roll, and replace lid. Place the jar of bees in a cupboard or dark, undisturbed place. In a day or so your bees will be calmer for you to retrieve them from the jar. Find a place near a sunlit window.
Bees go there when they get loose.
If the bees are too active, just let a few go to the window and retrieve them at your leisure. With your tweezers, grasp a bee by the head or thorax. Have the honeybee sting you, perhaps on your knee or forearm. Wait approximately fifteen or twenty minutes. Should you encounter difficulty breathing in that time, use your bee sting kit.
