WHICH MAY DRIVE OFF OR KILL SLUGS & SNAILS
Please note that the receipes included in this section are for historical interest only. It is in the U.K. to use any unlicensed pesticide.
- Aluminium sulphate spray or powder. Kills by absorbing water from the slime producing organs. Relies on chance contact with slugs. Not always effective. Best on warm humid evenings. Effective if reapplied every few days. Relatively safe to wildlife & pets. Can damage young plant foliage or even large lettuce - especially in dry weather.
- "Skipper soup": Included weeds, lawn mowings, kitchen waste & plenty of orange peel, mixed 50:50 with water. Was fermented 3 to 8 weeks until bubbled & smelled. Watered generously on ground - not over plants. Immediately killed slugs only, including keel slugs in ground. Applied around potatoes in August.
- Extract of fir tree seeds - strongly diluted.
- "Doc Abrahams No 3 spray": 3oz garlic chopped, soaked 24 hours in 2 teaspoons liquid paraffin. 1 pint (500ml) water & ¾oz liquid soap added. Mixed well& filtered. Stored in a non-metallic container.
- Dead slugs & snails left for a few days in water to ferment.
- Dead slugs & snails ground up & diluted with water - potentised homeopathic spray - sprinkled over garden.
- Extract of ragwort.
- Thin fermented bread dough poured on the ground - kills when eaten.
- Dried couch grass - lightly sprinkled - toxic to slugs.
- Metaldehyde & methiocarb baits ("Slug pellets"). Few slugs are killed outright. Many 'doped' slugs are easy picking for predators and therefore poison Nature's slug controllers. Slugs also absorb other pesticides. They significantly reduce the number of ground beetles (a major predator). They poison directly or indirectly birds, cats, dogs, hedgehogs, rodents, worms, insects. Predators concentrate the poisons in their bodies. Their loss can make the slug problem worse. Pets can become addicted to metaldehyde - the symptom is loss of control of the rear legs.
- Copper sulphate, bordeaux mixture, alum. They cause copper poisoning of the land in the long term.
- Salt. This is poisonous to most crops and the land.
