Kerb EX is an insect repellent specially developed for horses.

KerbEX Spezial is a pure oil against black flies. It should be applied very thinly to the affected areas of skin.

When applying to the auricle, care must be taken to ensure that the amount applied is sufficient to provide protection but does not come into contact with the eardrum.

Applying it every 3-4 days should be sufficient.
