An efficient sample treatment (recoveries between 82% and 95%) involving a solid phase extraction with a polymeric sorbent has been recommended, and no matrix effect was observed. Chromatographic analysis (4 min) was performed in reverse phase mode by using a fused-core column (Kinetex® EVO C18) with acetonitrile and ammonium formate as the mobile phase components, which was applied in isocratic elution mode. Method was validated according to the current European legislation. Not only was it selective, but it also displayed a wide linear range, good precision (relative standard deviation values lower than 9%) and sensitivity (low limits of detection (spinetoram J, 0.1–0.3 μg/kg; spinetoram L, 0.1–0.2 μg/kg) and quantification (spinetoram J, 0.3–1.2 μg/kg; spinetoram L, 0.4–0.7 μg/kg). Several honey samples were analyzed with this method and no spinetoram residues were found above the limits of detection. eng Attribution-NonCommercial-NoDerivatives 4.0 Internacional Development and
