Aircraft as a means of baiting ground squirrels


Development of techniques to apply ground squirrel bait by aerial application has been under way during the past three years, with 150,000 acres of rangeland treated in San Luis Obispo County, CA, during 1966. The types of suitable aircraft and application equipment are discussed, as are application techniques. Using crimped oat groats treated with sodium fluoroacetate (Compound 1080) at concentrations of 0.056 - 0.113%, efficacy has been good to excellent (90% or greater). Advantages of aerial application and the use of sodium fluoroacetate are discussed.
