Olfactory lures are important pest control tools, being widely used to attract animals to detection devices, traps, and poisons. For small mammals, like commensal rodents, almost all lures are foods. For invertebrates, however, semiochemical lures predominate and have done so for decades. Semiochemical lures overcome the inherent limitations of food-based lures, such as their perishability and inconsistent odour properties, and poor performance when foods are abundant. They can also provide benefits like low cost, ease of handling, and in-field longevity. Semiochemical lures for rodents would be a major advance, like that achieved for invertebrate monitoring and control, but their discovery has been constrained by the complexity of the challenge. Our research group is the first to achieve animal response-guided semiochemical lure discovery. We statistically integrated rapid field-based bioassays with scent chemical profiling and partial least squares regression to identify and test a suite of new single- and multi-compound rat lures. Field trials identified a tetrad and dyad mixture as the best performing lures, with an attraction rate of 0.61 and 0.60, respectively, compared to an attraction rate of 0.55 for the peanut butter standard. In total, 17 compound-based lures performed statistically as well as the peanut butter standard. We are currently working with an industry partner to encapsulate the lures as consumable, cost-effective pest-control products. Semiochemical lures will be particularly useful for multi-kill traps, toxic bait delivery devices, and remote monitoring devices that could operate for long periods without intervention. These devices offer substantial control program cost reductions but require long-life lures to realise their full potential
