I made this one using an instant noodle container and an Aqua Spike. I used my Dremel to drill a hole for the spike, to hold the roof up. The dremel helped me to add a bit of artistic flair by engraving the roof. It reads: 'The Drunken Slug Inn. Snails welcome.' and the 'S' in slug is a slug :)
Like the Mark I it seems to be most attractive to slugs rather than snails. So how do we deal with snails?
My housemate planted some cyclamens. She would usually scatter snail pellets around new plants like these but it hasn't been necessary. I had read that coffee grounds can be an effective snail deterrent so we've been scattering that closely around these new plants instead. Additionally, the grounds are a good soil conditioner. We would usually broadcast the grounds over the mulch. It feels good to use gentle, organic pest control that won't linger in the foodchain.
