Directions For Use

It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Application is prohibited directly into sewers or drains, or to any area like a gutter where drainage to sewers, storm drains, water bodies, or aquatic habitat can occur. Do not allow the product to enter any drain during or after application. Ready to Use: Dilution is not necessary. This product may be used with automatic dosing systems.

Beef Cattle, Cows and Calves

Lice*, Horn Flies

Apply product down the backline at the rate of 10 mL (1/3 fl oz) per head for cattle weighing less than 600 lb. or at a rate of 15 mL (1/2 fl oz) per head for cattle weighing more than 600 lb.

Repeat as necessary but, do not apply more than once every two weeks and do not apply more often than four times within any six month period.

*For reduction of sucking lice, two treatments at a 14-day interval are recommended.

Note: Exile® Ultra Pour-On is not effective in controlling cattle grubs. This product may be applied to cattle at any time during the year and not have host-parasite reactions, associated with grub treatment products, occur. Use Exile® Ultra Pour-On in an IPM (integrated pest management) system which may involve repeat treatments and the use of other pest control practices. Continued exposure of horn flies to a single class of insecticide (e.g. pyrethroids or organophosphates) may lead to the development of resistance to that class of insecticide. In order to reduce the possibility of horn flies developing resistance, it is important to rotate, on a seasonal basis, the class of insecticide used and/or the method of horn fly control. For advice concerning current control practices with relation to specific local conditions, consult resources in resistance management programs and your Cooperative Agricultural Extension Service.
