jen, you are going to be fighting an uphill battle, and many retailers sell this stuff. i am with iddee, the red let's us know it's in the hives.....lesser of two evils. we feed sugar syrup similar to the mix in hummer food, good to know the hummer food is in there with the red color in it.....also, folks that feed hummers are not going to stop feeding hummingbirds. i use sugar syrup to feed hummers, many do instead of the mix, i don't color it. what would you rather have?
we can't stop the bees from visiting a hummer feeder in dearths, and we can't stop folks from feeding the hummers.......just a thought for you....
