I suspect it is snails that cause most damage in my garden – by now the hostas have filigree leaves. In hot dry weather large numbers aestivate (rest in a state of dormancy) in the shelter of walls or under stones. I confess I crush them without compunction. I also destroy the clusters of pearl-like eggs under leaf-litter in the flower beds.
Large slugs provide a useful recycling service by eating decaying plant material. Small slugs do most damage. I protect choice plants with copper rings and the mulch of Strulch that I applied in the spring also seemed to be a useful slug deterrent. I was not impressed by the effect of fleece pellets. Gravel and egg-shells may make some difference. We encourage birds, newts, toads which keep down the population of both slugs and snails. I have not seen a hedgehog in years (eaten by the growing population of badgers?). Even ground beetles eat slugs. Biological control with nematodes would be expensive in a large area. I have slug-collected on damp evenings and cut them in half with scissors or dropped them into a strong salt solution, but in the end, on occasion, I somewhat guiltily do resort to poison starting with the organic pellets containing ferric phosphate before progressing to metaldehyde.
Have your say!
