This was a new one for me. I do remember talking about it though in old RP.
One of my hubby's ex co-workers collects coffee cans, drills holes in the
plastic caps and then put moth balls in the cans. She then set the cans on
the outskirts of her property. Apparently this works. I've never heard of
it before. ~ jan
