Abstract

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.
