Definitions

  • the present invention relates to rodenticidal bait systems consisting of an active ingredient-containing bait material and a packaging material matched thereto in the form of a ready-to-use bait.
  • indanedione derivatives and 4-hydroxycoumarins lower the prothrombin level in the blood. They cause rodents to die from internal bleeding.
  • rodenticidal compositions cf. for example DE 2 506 769; JP 48 023 942; CH 481 580; Tammes, PML et al., Acta Physiol. Pharmacol. Neer. J4, p. 423- 433 (1967); Paposci, L. Supplements
  • the rodenticidal active ingredient is either mixed with additives that rodents like to take (various cereals, sugar, oil, etc.) or added as a scattering powder in inorganic auxiliaries (talc, chalk, Ti0 2 powder, etc.).
  • the baits produced by this method have the disadvantage that their effect and attractiveness compared to the rodents decreases sharply over time.
  • the decrease in effectiveness and attractiveness is due not only to the chemical degradation of the active ingredients, but also to the degradation of the feed materials added.
  • the attractiveness of the bait can be maintained by combining the active ingredient with polymers such as e.g. Ethyl cellulose, polyoxyethylene glycols, hydroxypropyl methyl cellulose etc. coated (see e.g. DE 2 647 722 and CA 1 079 630).

  • This method has the disadvantage that only the active ingredient, but not the additives which are attractive for rodents, are protected from aging. For this
  • baits that contain rodenticides and hydrogenated oils or fats lead to contamination because the oils or fats partially dissolve the active ingredient and adhere very well to substrates such as plastics, carpets, paper, cardboard, wood, etc.
  • the present invention relates to a novel bait system which is characterized by its long attractiveness even in moist locations and easy to handle and, moreover, does not lead to contamination.
