"Safety" salt will kill the soil organisms and contaminate the water table.
The
various critters passing by would not likely find it tasty and wouldn't
take very
much - if they did, it would kill them as well. Salts are better soil
sterilants than
they are herbicides. They are not a good answer.
I think your best answer would be buried construction paper as a mulch.
