The sucking louse Haemodipsus ventricosus can affect domestic rabbits, and it usually found in breeding establishments, especially if husbandry standards are poor.[1] It is a large louse 1.5-2.5 mm in length and can be transmitted by direct contact.[1]

Lice are known to be vectors for tularemia and commonly affects wild rabbits.[2] There is discussion whether or not lice can act as a mechanical vector for myxomatosis.[3]

The entire life cycle of the louse takes 2-3 weeks depending on environment conditions.[1] The organism and eggs can be seen by the naked eye.[4]

Symptoms

Rabbit lice are commonly located down the spine, on the rump area and down the sides of the rabbit.[3]

Clinical signs include the following:[3]

  • intense scratching and irritation
  • thinning of the fur
  • bald patches

In very young rabbits, anaemia may also present in advanced infestations.[3]

Treatment

  • Ivermectin injections are the treatment of choice, again at 7-10 day intervals for 3-5 treatments.[1][3][2]
  • Selamectin (Revolution, Paradyne, & Stronghold).[2][5]
  • Imidacloprid.[3]
