If you are having
difficulty with bees visiting the
hummingbird feeder here’s one suggestion,

Make the sugar solution 1 part white sugar to five parts
purified water simmered/cooled in other words 1-5 ratio instead of the
usual  1 part white sugar to 4 parts
purified water simmered.  Bees won’t be
attracted but the hummingbirds will still drink it.

Remember this is not their food source.  The flowers and bugs around your yard provide
that.  This is a little extra treat.

Also remember not to use pesticides in your
yard.  Only use non toxic solutions for
some  bug control.  Otherwise you can have a balanced yard, if you
let the birds, lizards and nature do what they know best.
