You can spray Pistal directly on adult sheep for 4 to 5 seconds from a 30 to 40 cm distance. It is recommended to spray lambs only for a very short while, or to spray the product on a piece of cloth before applying it to their coat. We also recommend treating the stables. Keep the space closed off for about 15 minutes and make sure to air it out thoroughly afterwards.
If the sheep are once again infected with flies or other insects, treatment with Pistal can be repeated.
