Does my horse have lice infestation?

Lice are flat-bodied, tiny insects that can grow to be 2 - 4 millimeters long when fully developed, making them difficult to identify in the early stages of infestation. They eat the waste that the skin produces as well as physiological fluids. They live in numerous places of the horse's body, from the coat to the mane and tail, and breed in the thick coats that horses grow during the colder winter months. Haematopinus asini (H asini), the horse sucking louse, and Damalinia equi (D equi), the horse biting louse, can both infest horses and donkeys. Both species have a global distribution.

Common conclusions

Your horse doesn't show signs of lice infestation.

Your horse show few common signs of lice infestation. Look for the presence of lice. The hair should be parted, and the skin and proximal portion of the coat examined with the aid of light if indoors. The hair of large animals should be parted on the face, neck, ears, topline, dewlap, escutcheon, tail base, and tail switch. If the lice are present, consult with your veterinarian to give you a treatment plan. The lice should be treated every two weeks as their life cycle is short. Treatment any less frequently 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.
