For more than a month now I have been using 50% Jiffy cornbread mix with 50% baking soda and a small handful of sugar mixed in, as recommended by a farmer who told me how to control rats. “Rats can’t burp a fart,” he said. I have scooped up 6 rats so far—2 dead and 4 barely alive. I have not seen a rat, either. But I know they are eating the mix because I see the excrement. Let them. They’ll die. I don’t like killing anything but I had to do something. The hens have half a garage and a run. I put the mix in the half of garage they cannot get to. It isn’t the greatest thing for your dog or cat to eat but it is NOT poison, and if an animal eats a dead rat, the ingested mix won’t kill the animal. I can’t think of a better way to do this. I still spray coop twice a week with a peppermint mix spray. It just smells so good! Photo: those are my barn cats. They find rats and mice distasteful and will stick to the occasional butterfly.
