Ultra Boss Pour-On Insecticide is a ready-to-use topical insecticide formulated for the control of external parasites in livestock. It is labeled for use on beef and dairy cattle, calves, sheep, goats and horses, providing broad-spectrum control of lice, horn flies and face flies, and aiding in the control of horse flies, stable flies, mosquitoes, black flies and ticks.

The formulation contains 5% permethrin and 5% piperonyl butoxide, a synergized combination designed to enhance insecticidal activity. Permethrin delivers fast-acting control of parasites, while piperonyl butoxide helps improve overall effectiveness by supporting the activity of the active ingredient.

Designed as a low-volume pour-on, allowing for efficient application along the backline of the animal. This supports ease of use and reduces labor during treatment, making it practical for herd-level parasite control programs.

When used as directed, Ultra Boss provides extended control of horn flies for up to 8 weeks, along with season-long control of lice with a single application under appropriate conditions. This extended activity supports reduced treatment frequency and helps maintain animal comfort and performance during periods of high insect pressure.

Commonly incorporated into integrated pest management programs, where consistent parasite control is essential to maintaining herd health and minimizing production losses associated with external parasites.
