Device for catching snails and means for use in such a device

The invention concerns means for catching snails (4), preferably so-called killer snails (4). The means comprises forming a hollow between sides which are formed by plates (2). The plates are at least one outer side provided with hair- or scale-like barbs. Over the assembled sides there is placed a corresponding closed surface which on at least the inner side correspondingly is provided with hair- or scale-like barbs. Between the two surfaces is formed a passage allowing the snails to pass in one direction but hermetically closes off the passage of the snail in the other direction. The snails are lured into the passage via a bait placed in the centre of the trap. The bait comprises particles, e.g. liposomes having an outer shell made of a material which is resistant to the weather and attractive to snails, together with a core which is narcotising or killing snails.
