An insecticidal shampoo for killing and repelling flies, and for the treatment of lice infestations in horses. Directions: Thoroughly saturate the coat with one-part Dermoline Shampoo in ten parts of warm water. Pour Dermoline Shampoo as required over the back of the animal. Rub into a good lather with a soft brush adding more water as necessary. When clean, rinse thoroughly and dry. Take care to prevent the shampoo from entering the eyes or coming into contact with mucous membranes, by smearing petroleum jelly around these areas. In cases of lice infestation use at least 1 litre of shampoo per horse and ensure that all parts of the body are shampooed. Leave in contact for at least 10 minutes before rinsing off. Repeat 10–14 days later. The stable, blankets and grooming equipment etc. should also be treated with a suitable insecticide to avoid reinfestation.
