Bromethalin is a unique highly potent rodenticide exhibiting a mode of action different from anticoagulant rodenticides. Bromethalin provides a lethal dose to rodents in a single feeding with death generally delayed two to three days. Rodents do not discriminate against bromethalin bait; therefore, excellent bait acceptance is achieved with no prebaiting. Field studies have shown bromethalin bait to be highly efficacious against Norway rats and house mice under a variety of field conditions. Laboratory and field trial data indicate bromethalin is effective against known anticoagulant–resistant rodent populations. Toxicological data indicate bromethalin bait is relatively safe to nontarget species as well as to the environment.
