@samstonhill, Outstanding!! Just a thought, I know this works for snails but am not sure about Slugs.. Try sprinkling a little bit of water mixed with table salt around the border of your planting area. Snails simply dry out due to dehydration after a bit, but I do not know what will happen with Slugs. Be careful to not get the salt water on your plants as this kind of kills them to.

Good Luck and I love the updates!!
