LSU Research shows FIPRONIL AND IMIDACLOPRID does not work.
The research results provided a threshold concentration of imidacloprid that significantly reduces the toxicity of fipronil. Even 2.3 ppm (15 ppm in the solution) imidacloprid reduced the efficacy of fipronil. The termite survival numbers in the treatment of 100 ppm fipronil plus 15 ppm imidacloprid were significantly higher than in the treatment with lower imidacloprid concentrations (100 ppm fipronil plus 5 ppm imidacloprid and fipronil alone) at 48 hours. Both fipronil (under registered name Termidor«) and imidacloprid (under registered name Premise«) are widely used in the termite control market. The results indicate that the efficacy of Termidor« may be affected by the presence of Premise« in the field. http://etd.lsu.edu/docs/available/etd-07072010-144721/unrestricted/LUO_thesis.pdf
