Lice Infestation in Horses



Clipping of the coat is the best first step in treating lice in horses. This is because the longer the coat is, the more welcoming it is to lice--this is a great way to discourage them from migrating to and breeding on your horse. The thicker the coat the larger the numbers of lice; this is why the winter months are a better time for them to breed in large numbers.


The lice should be treated every two weeks as the life cycle is so short; treatment any less frequent can give the lice ample time to regrow in numbers and become an issue once again. An insecticidal medication may be the best method of treatment; a type of lice killing powder may also be used to dust the horse’s coat and kill the parasites as well.


Living and Management


Keeping the horse clipped when possible is a good way to slow down lice. It is also important to make sure that the treatment is administered often enough until the lice are eradicated.
