To make your own, just put four cups of water and one cup of sugar in a saucepan. Bring to a boil for two minutes, then let cool before filling your feeder. This recipe makes more than my feeder holds, so I just put the extra in the fridge until it is time to refill.
The hummingbirds are attracted to red on the feeder. If you don't have any red on your feeder, just tie a red bow on it, and they will come.
Readers, do you have any hummingbirds?
