Pestene Powder is an effective topical treatment for the control of lice, mites and fleas in poultry, dogs, cats, horses, calves and goats. It is produced from Derris dust which is considered a natural pesticide. It is to be applied weekly (or as required) directly on the affected animal, and also their bedding and environment. Sprinkle Pestene liberally through the coat or feathers and work thoroughly into skin. Pestene is not to be used on puppies and kitten under the age of three months, and use only as directed on the label.
