We present a search for B0 decays to charmless final states involving an η meson, a charged pion, and a second charged pion or kaon. The data sample corresponds to 383×106 BB̅ pairs collected with the BABAR detector operating at the PEP-II asymmetric-energy B factory at SLAC. We find no significant signals and determine the following 90% C.L. upper limits: B(B0a0-π+B(a0-ηπ-)<3.1×10-6, B(B0a0-K+B(a0-ηπ-)<1.9×10-6, B(B0a0(1450)-π+B(a0(1450)-ηπ-)<2.3×10-6, B(B0a0(1450)-K+B(a0(1450)-ηπ-)<3.1×10-6, B(B0ηρ0)<1.5×10-6, and B(B0ηf0(980))×B(f0(980)→π+π-)<0.4×10-6.
