Rodent repellents are chemicals which by taste or odour or possibly by both will prevent animal from feeding or gnawing. Such substances may be used in protecting an area from rodent infestation or in protecting packaged food, packing materials, electric cables, and other important vulnerable materials. Mature and healthy house rat, Rattus rattus of both sexes, was exposed to 5, 10, and 20% eucalyptus oil applied as spray in laboratory pens in bichoice tests. Each concentration was applied through three different modes of application, that is, daily, once, and alternatively in a week. Repellent effect of the oil was assessed based on food consumption from treated and untreated sides for four days. In overall, food consumption was significantly (P < 0.0001) low from treatment side compared to the untreated side indicating significant repellent effect of the oil at all the three concentrations tested. Repellent effect of the oil was, however, not found to differ significantly between the two sexes. Percent repellency in both male and female rats was apparently more with daily application of 5 and 10% eucalyptus oil. Present studies reveal the potential of eucalyptus oil in repelling away R. rattus; however, further studies may be conducted to enhance the persistence of repellent effect for longer period of time.
灭鼠剂是一类化学物质，它们通过味道或气味，或者可能两者兼具，来阻止动物取食或啃咬。这类物质可用于保护某一区域免受啮齿动物侵扰，或用于保护包装食品、包装材料、电缆及其他重要的易损材料。在实验室围栏的双选试验中，将成年健康的褐家鼠（Rattus rattus）雌雄个体暴露于以喷雾形式施加的5%、10%和20%桉叶油环境中。每种浓度通过三种不同的施加方式进行处理，即每日一次、一次性施加以及每周交替施加。基于四天内处理侧和未处理侧的食物消耗量来评估桉叶油的驱避效果。总体而言，与未处理侧相比，处理侧的食物消耗量显著较低（P < 0.0001），表明在所测试的所有三种浓度下，桉叶油均具有显著的驱避效果。然而，未发现桉叶油的驱避效果在两性之间存在显著差异。对于雄性和雌性大鼠，每日施用5%和10%桉叶油时，驱避率显然更高。目前的研究揭示了桉叶油对褐家鼠的驱避潜力；然而，可能需要进一步开展研究以延长驱避效果的持续时间。
