Lice and horn flies can cause severe irritation, skin damage and allergic responses in your cattle, which can affect weight gain. Animals can damage equipment and buildings by rubbing and scratching against them. If not controlled, lice can cause anemia, lower milk production and poor feed efficiency2.
How to Apply*
Apply the required amount of solution from a graduated device directly along the top of the back and top of the head of the animal.
The dose applied depends on the weight of each animal (see table below).

Integrated Pest Management (IPM)
When resistance is possible, rotation is critical. Pests can develop reduced susceptibility to an active ingredient over time. To help prevent this, consider rotating to a product from a different chemical class.
