Brodifacoum, like most anticoagulant poisons, has the advantage that one of its first effects is dehydration, forcing the rodent to move away from human habitation in search of water. As a result there is less chance that homeowners will encounter a dead rat inside their property. In any case, dehydrated bodies also dry out more readily, possibly leaving an odorless, carcass.
