How long would it take for the Mortein Rat Kill to degrade if it is buried in the backyard? Would it affect the soil or plant life in any way?
The chemical is not harmful to plants and, if used as directed it should not be hazardous to wildlife, domestic animals and man. The active ingredient in Mortein Rat Kill is brodifacoum. Because it is quite stable at room temperature, it is important that unused portions are disposed off carefully. You should dispose of empty containers and unused and untaken baits by burying in an approved dump.
