AiM-L VetCaps®

AiM-L VetCap is a scientifically developed gelatin capsule containing an Environmental Protection Agency (EPA)- approved topical insecticide proven effective for control of horn flies and lice on cattle. The AiM-L VetCaps are specifically engineered to withstand transportation and handling, yet burst upon contact with the animal. AiM-L VetCaps contain 10 mL of lambda cyhalothrin encased in a specialized capsule to be used exclusively with the VetGun.

The VetGun

The VetGun is the only approved delivery system for the AiM-L VetCaps. It’s simple to operate, accurate and reliable. The VetGun is designed and manufactured with the highest standards and materials to consistently deliver each VetCap to the target animal and is supported by an exceptional service guarantee.


  • The AiM-L VetCap system reduced horn fly numbers by more than 90 percent in a 40-day trial.1
  • A single VetCap dose applied to one side only, effectively controlled horn flies on both sides of the animal and reduced horn flies below the accepted economic threshold of horn fly infestations.1
  • VetGun delivery was demonstrated effective for remote delivery of insecticide to control horn flies.1
  • When tested in cattle on Texas ranches, AiM-L VetCaps provided very effective horn fly control (>98 percent) for four weeks after treatment.2
