A fable from another era about mothballs Loose mothballs often get eaten by wild birds (which have no sense of smell) with very unhealthy results. I recommend a cluster of 6 or 8 mothballs however, bundled up in something like an old sock, to repel certain wild animals and loose dogs (which is a subject in itself). It’s NO LONGER a responsible recommendation to scatter mothballs on the ground. This is no longer suggested by researchers, or any knowledgeable or environmentally-aware person.
