I am having problems with the yellow jackets and ants. Feeder hanfing in the front from an awning had about 100 or more dead ants in it. One in back hanging from soffit had about 100 or more dead bees in it and the bees cover the top, where the holes are and run the hummingbirds away. I hope this weekend with cooler temps will keep the bees away. The Hummingbirds will leave here next month as our days will be getting shorter. I didn't have this problem for couple of years, now they are back. Don't use any poisins as you will kill the hummingbirds also. I live in a rural area too.
