Look around your yard or apartment grounds and find a plant, with flowers, that has bees feeding. Then set a shallow dish in the plant with 'bee food.' As time goes by, it might take several days, the bees will start feeding on the bee food you put in the dish. Now, you can slowly move your 'feeding station' to a more convenient location so you can keep it supplied with bee food. I like to move mine to my front porch. There, it is out of the winter weather and easy for me to keep supplied with bee food.
Now, to make bee food. Place equal parts of sugar and water, 1 cup to 1 cup of water, in a pot and boil for about 1 minute. This will drive off all the nasty stuff your water company puts in your water to make it 'healthy' for you to drink. The bees will love it. I put in a little red food coloring to help attract the bees.
If this works for you as it has worked for me, be prepared to use up to 10# of sugar a week because these little suckers can suck up the sugar water. Pictures attached. It is a lot of fun to watch them, they will not sting and will let you watch them and get very close to their feeding.
Enjoy and let me know if you try this, the bees and our food source will thank you.
