Precautionary Statements


Exile Pour-On Caution

Harmful if swallowed, absorbed through the skin. Causes moderate eye irritation. Avoid contact with skin, eyes or clothing. Remove contaminated clothing and wash before re-use. Wash thoroughly with soap and water after handling and before eating, drinking, chewing gum, or using tobacco. Wear rubber or nonpermeable protective gloves when applying this product. Data indicates this product to be a contact allergenic. Do not apply product to the face of cattle.

Environmental Hazards: This pesticide is extremely toxic to fish. Use with care when applying in areas adjacent to any body of water. Apply this product only as specified on the label.

To protect the environment, do not allow pesticide to enter or run off into storm drains, drainage ditches, gutters or surface waters. Applying this product in calm weather when rain is not predicted for the next 24 hours will help to ensure that wind or rain does not blow or wash pesticide off the treatment area.

Physical or Chemical Hazards: Do not store near heat or open flame.

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.

Restrictions: Do not apply to lactating or dry dairy cows, or to the face of beef cattle, cows or calves. Exile® Pour-On is not recommended for use on veal calves.




Beef Cattle, Cows and Calves

Lice*, Horn Flies

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