I have a small group of honey bees all over the hummingbird feeder ..?

Honey Bees are harmless and won't attack unless directly threatened as by stinging they are in effect killing themselves.

I would leave them alone.. they will move themselves and with the colder whether coming they won't be around much longer anyway. By disturbing them you are likely to just cause them harm. If you don't want them there I just wouldn't fill up your feeder until you get back.

You should just reassure your house-sitter they're harmless and not to do near them.

I have had that hindrance additionally. Before you set the feeder out or while you blank it, spray Pam or equivalent liquid oil round openings. This does now not damage birds however maintains insects away. You will must do that at any time when you wash and fill up feeder.

Purchase a bee guard for you feeder.
