Snails away, already the third summer

The remedy is excellent. I use it already the third summer. If screw (the first year masses, from the second year less and now in the third year almost none more) emerge there in the evening to nibble something from the slug pellets and the next morning is resting in the bed.
To what extent it affects negatively to other animal, I can only write from observation: My hedgehogs are all the year still busy road, just at the sparrows, titmice or blackbirds. The number of lounging in the garden cat was not so much, but I guess more the effect of the 200m distant main road.
