Work Smarter, Not Harder

AiM-L™ VetCaps

AiM-L™ VetCaps are scientifically developed gelatin capsules designed to be used exclusively with the VetGun™. Each 10 mL capsule contains lambda-cyhalothrin (a pyrethroid), an Environmental Protection Agency-registered topical insecticide proven effective for control of horn flies, and lice on beef cattle.

As a topical insecticide, users can expect a quick knock-down of horn fly and lice populations as they come in contact with AiM-L on the skin and provides 3-6 weeks of horn fly control.

AiM-L VetCaps are engineered to withstand transportation and handling, yet burst upon contact with the animal.

Horn fly treatments with AiM-L VetCaps can be rotated with AiM-A Abamectin™ VetCaps as part of an effective resistance management program.

Use VetGun to control horn flies on your cattle where and when you need it.


Read the product label for full instructions, handling, warnings and precautions.

Step 2: Treat with AiM-A when flies approach approximately 200/animal 

Step 3: Treat with AiM-L four weeks after AiM-A treatment

Step 4: Treat with AiM-A when flies approach approximately 200/animal

During winter and early spring, treat with 2x AiM-L, two weeks apart to control lice.
