The Dispersal of Fumigant Gases in Warrens of the European Rabbit, Oryctolagus cuniculus (L.)

Abstract

Comparative data are presented on the dispersal in rabbit warrens of four fumigant gases: chloropicrin, phosphine, hydrocyanic acid gas and carbon monoxide in exhaust gases from petrol engines. Investigations of the characteristics which affect their performance as warren fumigants are described. Factors affecting the success of warren fumigation are discussed.
