|Toxin||Single or multi feed?||Advantages||Disadvantages||CSL required?||Antidote|
|Brodifacoum||Single||Useful for controlling low numbers of possums. ||High risk of secondary poisoning. Builds up in the environment. Can build up in feral game meat and livestock with inappropriate use.||No||Yes|
|Cholecalciferol||Multi||Low risk of secondary poisoning. Can be used on all densities.||Acute toxin, requires multiple feeds. Can be more expensive than other options.||No||No|
|Feratox (encapsulated cyanide)||Single depending on possum numbers||Effective knockdown tool.||Acute, fast acting toxin. Builds up in the environment.||Yes||Yes|
|Pindone||Multi||Can also be effective on rats.||First generation. Possums have to eat a significant amount to consume a lethal dose. Medium risk of secondary poisoning.||No||Yes|
(diphacinone + cholecalciferol)
