Selectivity of Ferafeed paste bait treated with a rodent repellent a cage trial

Abstract

FeraFeed is a nontoxic prefeed paste bait used in conjunction with Feratox cyanide capsules for the control of possums The selectivity of a formulation of FeraFeed containing a rodent repellent was tested in a cage trial with Norway rats and possums Rats were strongly discouraged from eating the material and yet readily consumed nontreated FeraFeed paste while possums were not deterred Incorporation of the repellent should therefore improve the costeffectiveness of using FeraFeed/Feratox in possum control Additionally use of FeraFeed/Feratox for monitoring possum populations may be improved by the reduced interference by rats
