Abstract

Effectiveness of four cabbage baits was tested on Belding (Spermophilus beldingi) or Townsend (S. townsendi) ground squirrels. Ground squirrel activity reduction and number of above ground deaths/ 100 lb. bait applied were as follows: 0.00625% sodium monofluoroacetate - 94 1/2%, 2-1/3; 0.29% strychnine alkaloid - 86%, 17; 0.19% strychnine alkaloid - 73 1/2%, 10. A 0.8% zinc phosphide bait was not well accepted; activity was reduced 39%. Two cottontail rabbits (Sylvilagus nuttalli) and one badger (Taxidea taxus) were found dead in treatment fields after treatment.
