You know the struggle. You find the perfect place for your hummingbird feeder, you know the one, right outside the kitchen window, and the next time you look, there are ants on, in, and around your hummingbird feeder.
Once they are inside the feeder, they will die and cause mold and fungus to grow in the food. It’s not healthy for the birds and besides, who wants to keep killing ants?
Ants have to find a way to crawl on to the feeder in the first place, so if you can keep them from reaching the feeder, you’ll solve your problem. Enter, the ant moat.
This cool invention is simply a small reservoir for water that prevents the ants from crawling down the string that hangs your hummingbird feeder.
The moat is hung between the feeder and the hook it hangs on. Ants can not cross the water and thus they never reach the feeder. Just make sure you keep water in it.The birds may also drink out of this for fresh water, so keep an eye on it too, and change the water when needed.
I am pretty sure that you can build one yourself (out of an old liter soda bottle). But if you want to buy one already made, check this link out
