I finally found a way to keep ants off my hummingbird feeder! I tried baking soda---they still crossed through it. I tried corn starch, which from what I read, they eat it then die. I highly recommend this type of feeder, but any feeder with a moat will do:
The top of this feeder is separate from the rest of the feeder. I tried just water, but that didn’t phase the ants…they simply “swam” to the edge, then proceeded to steal food.
50% water, 50% rubbing alcohol! Since I’ve kept this top filled with this mixture, I have had no ants crawling all over the feeder as they did before, and only have dead ants floating around in this mixture. It works, yay!
