Summary
Over eleven hundred range cattle were treated with insecticide-impregnated ear tags and observed for horn fly control. Tagging rates compared were herds with one or two tags on each cow, two tags on part of the cows, one tag on half the cows, one tag on each calf (none on the cows) and fenvalerate versus permethrin as the insecticide in the tags. Results from all herds studied showed reductions of 90 to 100% for horn flues after 60 days of treatment for as long as 125 days.
