Of five commercial plant extracts (citronella, garlic oil, neem extract, pine oil, and pyrethrum), citronella was found to be effective in deterring the infestation of cartons containing muesli and wheat germ by red flour beetles. The chemical components were applied as part of a coating on the carton board. In an experimental set up that accelerates infestation over a 2 week period, citronella-treated cartons (0.2 g/m2 of carton board) reduced beetle infestation to approximately 50% of the level observed in control cartons. Evidence was provided to indicate that an insect repellent effect persists for at least 16 weeks. Additional work on the controlled release of the insect repellent would be required to prolong the effect.
在五种商用植物提取物（香茅、大蒜油、印楝提取物、松油和除虫菊）中，发现香茅能有效阻止赤拟谷盗对装有谷物片和小麦胚芽的纸箱的侵扰。化学成分作为纸箱板涂层的一部分使用。在一个为期2周加速侵扰的实验装置中，用香茅处理过的纸箱（每平方米纸箱板0.2克）将甲虫侵扰率降低至对照纸箱中观察到的水平的约50%。有证据表明驱虫效果至少持续16周。若要延长效果，还需要对驱虫剂的控释进行更多研究。
