Fire ants are horrible. My chickens try and stay out of their way. I use the poultry garden dust too. Chewy and tractor supply both carry the vaults. Amazon does also.Ahhhhhh, finally someone who deals with my very problem! ANTS!!!!! I HATE them and they are my nemesis! And more specifically, FIRE ANTS! Everyone talks about PESTS, but no one ever lists ants as one of them.
I have a brand new, large Grandpas Feeder (the expensive treadle feeder) sitting in its box. It took all of FIVE minutes for the ants to find the feed. All my chicken feeders are hanging, just because of the ants. Of course they gather on the ground under the feeders, but I dust underneath them once a week with Garden and Poultry Dust which kills the ants in minutes...and keeps working.
Now to the containers you mentioned. I have never seen nor heard of them. They look like very sturdy, hard plastic. Ants can chew through most anything, but these look like it’d be dang near impossible for them to chew through. And the plastic looks opaque which would keep light out. Awesome! Thanks for posting about these little storage solutions.
