The preferred food items of the slugs Laevicaulis alte and the snails Achatina fulica were used to prepare 'poison baits' by injecting the pesticides 'Rogor' and 'Nuvan' to kill these mollusc pests. The 'poison baits' prepared with Trichosanthes dioica and Lycopersicum esculentum were accepted by 100% individuals of both the species irrespective of the pesticides used. In all cases the slug and snail individuals died within a considerable length of time following consumption of the bait. The importance of using 'poison bait' lies not only with the sure success in killing the pests but also with the 'safe use' of toxic materials in order to avoid environmental hazards.
