The results showed that in the no-choice feeding tests in the laboratory, 100% of the animals died in all experimental groups and zero in the control groups. Time to death did not differ significantly between vertox pellet and vertox block bait in either test/feeding regime. However, with vertox past, a relatively longer time to death was observed. The three baits were therefore tested under field conditions on mouse populations and showed the following efficacy in terms of mouse mortality after three weeks: 83.33% with vertox pellets; 72% with vertox block and 95.33% with vertox past. The results obtained highlighted the good efficacy of the three brodifacoum-based baits in heterogeneous (resistant or not) mouse populations.

However, an additional study is needed with the same anticoagulants only on resistant rodent populations.
