AiM-A VetCaps are softgel capsules containing abamectin parasiticide for control of horn flies in beef and non-lactating dairy cattle over 600 lbs. VetCaps are fired from a VetGun (sold separately) at a range of 15' - 30' away. Capsules burst upon contact with the animal to deliver insecticide in a similar way to pour-on products. Simply aim, shoot, and treat. Each AiM-A VetCap contains 10 ml of abamectin. Apply one VetCap per animal over 600 lbs. When tested, VetCaps provided effective horn fly control for 4 weeks. Cattle are easily treated while milling around or feeding, without added stress or labor. Allows one person to easily apply insecticide from horseback, pickup, ATV, or while on foot. Saves time and puts you in control of when and where you treat your cattle. AiM-A VetCaps offer effective in-season control when rotated with AiM-L VetCaps. Typical in-season rotation includes the use of AiM-L when flies begin to appear, followed by AiM-A when flies reach approximately 200 flies per animal, followed by AiM-L four weeks later. Within any 12 month period, do not treat any animal with this product more than once, or with any other product containing abamectin, including abamectin insecticide ear tags.
