In the title compound, C(19)H(14)Cl(2)F(3)N(5)O(2), which shows insecticidal activity, the dihedral angle between the pyrazole and pyridine rings is 68.15 (16)°. In the crystal structure, the mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds and an intra-molecular N-H⋯O inter-action also occurs. The F atoms of the -CF(3) group are disordered over two sets of sites in a 0.800 (8):0.200 (8) ratio.
