How to get rid of Hornets at my Hummingbird feeders?

I had the same issue a few days ago. I had just put fresh nectar in the feeder and the yellow jackets showed up in droves. Around dusk they settled down, so I hosed off all around the feeder, then moved the feeder to a different spot. I hosed off the area again, then moved the feeder back. This seems to have solved the problem.

They are eating the sweet so wash the holes and guards so no sweetness on them and then fill them less full. Hummers have ability to get long tongue into liquid but no long tongue on insects. This may be all you need.

You might try handing a commercial Hornet trap in a different part of your yard, such as, "W.H.Y. by Rescue" found at Walmart. I used a kit successfully years ago, which was a bag that was filled with a foul smelling substance that would trap them inside the bag (place this away from and upwind from your home, very stinky!). Seems they are attracted to stuff that smells like rotting flesh. Also, you might try a more friendly approach, by saturating cotton balls or sponges with peppermint oil and hang/place them around your yard and by the roofs eves, I don't know if this will bother the hummingbirds or not. I have used a round japanese paper lantern or a brown paper ball shape that mimics hornets nests, hang that in a near by tree or from your roofs eve, being territorial, hornets/wasps will be discouraged from traspassing on another hive's turf. Good luck.

put traps with bacon in them up. Get rid of them this year and get the traps out early next year and you might get the queen. The others will leave looking for her. Also a yellow sticker thing. Hang one up and that gets a lot too.

I would make a recycled bottle wasp/hornet trap .... https://www.youtube.com/watch?v=B2VOjRwJUMI when you join the top of the bottle to the bottom, you can poke 3 small holes on the sides and put twine through them to make a hanger.
