VetGunTM Applicator


Product Information

VetGun is the only approved delivery system for treating external parasites on cattle using AiM-L™ and/or AiM-A Abamectin™ VetCaps — scientifically developed capsules filled with a measured dose of insecticide.

AiM-L and AiM-A VetCaps can be used to deliver a "one-two punch" for in-season horn fly control – working to combat horn fly resistance.

Along with its simple and accurate operation, VetGun is built to last. It’s exceptional engineering, manufacturing and quality of materials are underscored by an exceptional Lifetime Warranty. Should any part fail or become defective due to manufacturer materials or workmanship, Huvepharma will repair or replace at its discretion free of charge. Conditions apply.

AiM-L VetCap 10 mL capsules contain lambda-cyhalothrin (a pyrethroid), an Environmental Protection Agency (EPA)-registered insecticide proven effective for control of horn flies, and lice on beef cattle weighing over 600 lbs.

AiM-A VetCap 10 mL capsules contain abamectin (a macrocyclic lactone in the avermectin family), an Environmental Protection Agency (EPA)-registered insecticide for effective treatment of horn flies on beef cattle and non-lactating dairy cattle weighing over 600 lbs.

The AiM-L and AiM-A VetCaps are specifically engineered to withstand transportation and handling, yet burst upon contact with the animal. Used properly, VetCaps deliver a consistent and accurate dose of insecticide to each animal.

Storage and Handling:

Please note storage and handling requirements for VetCaps as they are sensitive to prolonged cold temperatures and humidity. Store VetCaps in conditions where relative humidity is kept between 30% and 50% and temperatures are maintained between 50 F-80°F.

Dosage and Administration


Use AiM-L and AiM-A VetCaps exclusively with a VetGun and in accordance with use directions and treatment method recommendations.

  • Apply when animal is between 15 and 30 feet distance from the user.
  • Do not apply treatment when bystanders are within 30 feet of the animal.
  • Do not apply to any animals in or within 10 feet of bodies of water. AIM VetCaps are designed for use only with the VetGun that carries the VetCap registered label. Using any other application device or method could be unsafe, ineffective and/or cause harm or injury.


Apply a VetCap to the upper two-thirds side of the animal's body, anywhere between the front shoulders and six inches ahead of the base of the tail. Apply one VetCap per animal.


Treatment for horn flies with AiM-L can be repeated as needed, but not more than once every two weeks and do not apply more often than four times within any six-month period. For optimal lice control, an initial application followed by a second treatment two weeks later is recommended. It is recommended that AiM-A be applied once in the season to help break the cycle of horn fly resistance.

Producers should plan VetCap applications to horn fly populations causing economic damage &mdash generally when numbers approach 200 per animal. By minimizing the time horn flies are exposed to each insecticide, and by rotating chemical classes, parasites have less time to develop their defenses.



1 VetCap (10mL) for cattle over 600 pounds. Apply one VetCap per animal.
