Penny Pincher’s Slug Solution Myth Busted?

Heard of a solution to our slug problem:  surround your prized plants with a circle of pennies to keep the slugs away.  For pennies you can keep those slimy suckers at bay!  Worth a try.  The thought is that slugs get a “shock” when they touch the copper and dislike it so they find greener pastures.  The result?

Corporate slug?

Maybe wheat pennies will work better. Maybe a trip to the local “Rent-a-Duck”?  Maybe some well placed slug pellets!
