Hi ! I have read somewhere that the most effective way of killing slugs was to use nematodes, that we do find here in France, but also that lack of snails and slugs meant that they disappeared altogether through sheer lack of food. I find this hard to believe since they reappear now and then gobbling up a snail they have done in. Do they hibernate slowing down their metabolism to a minimum ? Has anyone actually tried caffeine, iron phosphate and compared the results in terms of efficiency ? I have been looking for an organic, environment friendly way of keeping slugs down. however apart from letting a bunch of bantams hens loose onto the garden whilst I was clearing the ground ready for seeding I have not found anything really successful. I am reluctant to use slug pellets ( methyl aldehyde ). Kindly submit your suggestions, the slug population is particularly strong this year : Wettest spring for 34 years here in the Toulouse area.
