Rodenticidal soft bait compositions are provided which consist of a mixture, in the form of a paste, comprising vegetable flour, a fat which is not completely liquid at a temperature of 35℃ and at least one rodenticidally-active substance. The vegetable flour is present in the mixture in an amount of at least 60%, preferably 62 to 78%, by weight based on the total weight of the mixture. The weight ratio of the vegetable flour to fat in the mixture is 4:1 to 8:1, preferably 5:1 to 7.5:1. The soft bait compositions are extremely palatable to rodents such that rodents are encouraged to consume a sufficient amount to deliver a lethal dose of rodenticide in a single sitting. Also provided is a method for manufacturing the soft bait composition of the invention.本發明提供由呈糊劑形式之包含植物粉、在35℃的溫度下不完全為液態的脂及至少一種滅鼠活性物質之混合物組成的滅鼠軟餌組合物。植物粉係以基於混合物總重量計至少60重量%、較佳62至78重量%的量存於混合物中。混合物中植物粉相對脂之重量比為4：1至8：1，較佳係5：1至7.5：1。該軟餌組合物對於嚙齒動物而言極其可口，以促使嚙齒動物一口氣攝取足以輸送致死劑量滅鼠劑的量。本發明亦提供一種製造本發明之軟餌組合物的方法。
