The ants were invading my hummingbird feeder!
So I did a little research and found that I needed to add an ant moat. The ants crawl up the pole but can't get to the feeder because there trapped by the water! GENIUS.
A little craftiness and a hot glue gun does the trick.
Use an aerosol can lid. Drill a little hole and take some wire or a coat hanger. Use the hot glue to attach the wire and close up the hole so the water does not drip out.
Now the hummingbirds don't have to share with the ants only the bees.
