Yes, I did. And I’m not ashamed of it.
This is what the ground looked like under the capillary box that I grew tomatoes in last year (and weeds this year, since I didn’t actually plant anything in it this year…). Or rather, this is what it looked like under the capillary box after I had poured two litres of boiling water over the ground, so these will be dead slug eggs.
That would be the mother/father of the eggs I killed off. I do kill all kinds of slug eggs, but I don’t mind having a small population of leopard slugs in my garden. For one things they are significantly more stylish than the killer slugs, and secondly they also have a knack for hunting down other slugs and kill them. (And they don’t breed in the same ridiculously prolific fashion as the killer slugs…)
It IS a pest in some ways, but all things considered it’s good to have them in the garden since they are preferable to other slugs and will keep them at bay, at least to some extent.
NOTE: This is only true in areas where the Iberian slug, i.e. the KILLER slug, has invaded, so Northern mainland Europe. Had I gardened on the British Isles, for example, I’d have killed it on sight!
(Also, according to wikipedia, they are rather clever little fellows: “Limax maximus is capable of associative learning, specifically classical conditioning, because it is capable of aversion learning and other types of learning.”)
And now enough of this; I finished digging out the unnamed flower bed in the lawn last night, so now it’s time to find some compost and dig in so I can get some stuff planted in there!
