Provides effective horn fly control for beef cattle and non lactating dairy cattle with 10 mL gelatin capsules containing abamectin, an EPA approved systemic insecticide. Designed exclusively for use with the VetGun system, each capsule is built to withstand handling and transport while bursting on contact to deliver the treatment quickly and effectively. One capsule treats cattle weighing 600 to 1200 pounds, allowing for convenient, low stress application from a distance. AiM A capsules can also be rotated with AiM L capsules as part of an in season resistance management program to help maintain effective horn fly control.
