I plant flowers in my perennial beds specifically to feed the hummingbird families that come back summer after summer, but I also like to hang hummingbird feeders in the front and in the back of the house. I discovered this clever Ant Moat at Lee Valley Tools that solved my problem of unintentionally feeding the nearby ant colonies:
No matter where you hang your feeder, the ants cannot get to it as long as you keep the umbrella full of water! No more ants in the sugar-water reservoir, no more ants crawling up the pole or the walls of the house to get to the feeder…nada!
UPDATE: Not only do our Ant Moats keep the Hummingbird feeders ant-free, but they provide the small birds in the neighbourhood a perfect place for a drink or a quick bath! An unintended but enjoyable dual function 🙂
Dissolve the sugar in the boiling water.Add the boric acid and stir until dissolved.
Take any pint-sized plastic container and cut small holes into the sides at the bottom to allow ants access to crawl inside.Dip cotton balls into the solution, and place inside the container.Seal the container with the lid, and place the container on a pathway that the ants are using.
The ants will eat the solution, and take it back to the other ants in the nest, where it will “build up” and eventually destroy the nest.The solution can be refrigerated and stored for a couple of weeks if it is carefully labelled.
