Dose response curves of flea mortality for flumethrin or imidacloprid or a 1: 1.85 combination of flumethrin and imidacloprid. The dose response curves show mean % mortality after 24 hours contact against Ctenocephalides felis on glass vial surfaces treated with different doses of flumethrin, imidacloprid or a 1: 1.85 combination of flumethrin and imidacloprid (mean data from 2 separate trials; curves including 95% confidence interval as dashed lines calculated with SigmaPlot for Windows 11.0 (Build 11.0.0.75, ^© 2008 Systat Software, Inc.).
