So….many Hummingbird feeders are a massive ant magnet. Once infested with ants the little birds will not drink.
The trick is..one has to devise a way stop this theft.
A few years ago….I built an exotic.. ..ant mote from stainless steel that didn’t work. The next day or two I happened to touch up something with a paint can….wait what..here is my mote
I got a good piece of solid wire..just bigger than paperclip diameter. I drilled a tiny hole through bottom of cup middle. I then inserted the wire through the hole and bent a hook on each end.. Once that’s done ..I use hardware store epoxy to glue it in place.
Once set..set it up..fill the mote with water…really pisses off the ants.
As a bonus….other birds drink the water..
As a note ..I did see the other day..some have come up with this idea….maybe from my old FB post and sell it as an option.
