Those little fuckers will destroy yr garden if you let them.
You can leave beer out in a cooking pot and they'll climb the walls then drown in it - but I don't drink and don't want to buy beer
Sooooo you can capture 4 or 5 of them, cut them in half and impale them on skewers and line your garden Vlad-like and that will, I shit you not, scare the rest from coming in.
Unfortunately, slug eggs are super fucking tiny and are just left random-where in the soil, so there's nothing short of nuking the ground that we can do to get rid of them...so the staking continues.
As someone who is from Or*n, rofl. My parents even have a story about their dog from when I was a baby freaking out about a banana slug while we were camping.
