An Aerial Method of Dispensing Ground Squirrel Bait

Abstract

A need for improving and updating rodent-control methodology prompted this study of the use of aircraft for baiting destructive populations of ground squirrels. Both spot and strip baiting by air were effective when applied in narrow swaths at a rate of 6 lb/swath acre. The aerial technique of dispersing bait gave good control when the ground squirrel population was foraging extensively for seed. The bait need be applied to only a fraction of the ground surface of squirrel-infested rangeland.
