We present a search for B decays to charmless final states involving charged or
neutral a0 mesons. The data sample corresponds to 89 million BBbar 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: BR(B0 -> a0-pi+) < 5.1x10{-6}, BR(B0 -> a0-K+)
< 2.1x10{-6}, BR(B- -> a0-K0bar) < 3.9x10{-6}, BR(B+ -> a00pi+) < 5.8x10{-6},
BR(B+ -> a00K+) < 2.5x10{-6}, and BR(B0 -> a00K0) < 7.8x10{-6}, where in all
cases BR indicates the product of branching fractions for B -> a0X and
a0 -> etapi, where X indicates K or pi.
