I’m using old pennies in an attempt to keep slugs and snails out of my hives, because apparently they don’t like the taste of copper.
I could spend $25 at my local hardware store for 15 feet of something called “Copper Mesh Fence Barrier” (at $1.67 per foot) to keep the slimy guys out of my hives. Or I can use up 24 cents in pennies per hive to do the same thing. Will it work? I don’t know. It seems the snails can still slink right up the sides of the hives, but I’m guessing most of them get in through the bottom entrance. I’ll update this post as soon as I find clear evidence that does or doesn’t work.
