I have tried making a sweeter feed mix 2 to 1 sugar water, in an another feeder and attracting the bees away, from the 4 to one hummingbird mix, (didn’t work) the bees just used both feeders, I tried spraying the bees and the feeder with soap and water, it chased the bees away for about 5 min but the soap migrates into the syrup and is not as attractive to the birds, The bees still come.
