Field trials of bromadiolone against infestations of warfarin-resistant Rattus norvegicus

Abstract

Baiting with 0·005% bromadiolone in medium oatmeal or soaked wheat completely controlled infestations of warfarin-resistant rats on farms when surplus amounts of the poisoned baits were maintained until rats ceased to feed on them. The speed with which control was achieved was the same as with other anticoagulants that have been tested in this way. Poison baiting with 0·005% bromadiolone for only 1, 4 or 7 days achieved respectively about 49, 77 and 81% control of similar farm rat infestations. © 1981, Cambridge University Press.
