Often, the most effective strategy is employing toxicant\u2010laced baits, which also must be designed to specifically attract and be preferred by the targeted species for optimal species\u2010specific effectiveness. However, traditional methods for measuring bait preference are either noncomparative, meaning that most animals only ever taste one bait, or suffer from methodological or conceptual limitations. Here we demonstrate the value of direct comparison food preference assays using the invasive and pest ant\n                      <jats:italic>Linepithema humile<\/jats:italic>\n                      (Mayr, 1868) as a model.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      We compare the food preference sensitivity of noncomparative (one visit to a food source) and sequential comparative (visiting one type of food then another) assays at detecting low levels of aversive quinine in sucrose solution. We then introduce and test a novel dual\u2010choice feeder method for simultaneous comparative evaluation of bait preferences, testing its effectiveness in discerning between foods with varying quinine or sucrose levels. The nonsequential assay could not detect aversion to 1.25\u2009m\n                      <jats:sc>m<\/jats:sc>\n                      quinine in 1\u2009\n                      <jats:sc>m<\/jats:sc>\n                      sucrose, yet the sequential comparative approach detected aversion to quinine levels as low as 0.94\u2009m\n                      <jats:sc>m<\/jats:sc>\n                      .

This innovative approach offers a promising tool for rapid and sensitive testing of bait solutions, contributing to the development of targeted control strategies.
