Body lice and so called "ticks" or keds are the most serious of the external parasites which infest sheep in Western Australia, and unless they are controlled by systematic dipping, these pests can be the cause of considerable financial loss to flocl owners. The sheep body louse (Damalinaia ovis), which is able to propagate under hot and dry conditions, has a wide distribution and occurs in both the agricultural and pastoral areas. The so-called tick or ked (Melophogus ovinus), has a much more restricted distribution and is confined to the higher rainall areas of the South-West proportion of the State.
