I have honey bees and hummers. The solution that has worked for me is to use a bee feeder close to Hummer feeder. These can be found at bee supply stores or online. Instead of the recommenced 4 to 1 Hummer mix, the bee feeder uses a 50/50 mix more suited to honey bees and yellow jackets. The design of bee feeder only accommodate insects, thus draws the pest from the Hummer feeders, also water cup or barrier holding water prevents ants from crawling to Hummer feeders.
