Horse Lice, Mite & Parasite Treatments

Horse Lice & Mite Treatments — Identify Fast, Treat Thoroughly, Prevent Reinfestation.

External parasites are more common in horses than many owners realise — particularly during the winter months when horses are stabled more frequently and in closer contact with one another. Lice and mites cause intense itching, coat damage, skin irritation, and in heavy infestations can lead to significant hair loss and secondary skin infections. Early identification and prompt, thorough treatment are essential to bring an infestation under control and prevent it spreading through a yard.

Common External Parasites in Horses

• Biting lice (Damalinia equi) – Feed on skin debris and cause intense itching, particularly around the mane, tail, and flanks; visible to the naked eye as small, pale insects moving through the coat
• Sucking lice (Haematopinus asini) – Feed on blood and are most commonly found around the forelock, mane, and lower legs; cause more severe irritation than biting lice
• Chorioptic mites – The cause of mange in horses; typically affect the lower legs and pasterns, causing intense itching, stamping, and crusty, thickened skin — particularly common in feathered breeds

Treatment & Prevention

• Topical insecticidal washes & sprays – Applied directly to the coat and skin to kill active lice and mites; repeat treatment is usually required after 10–14 days to catch newly hatched eggs
• Dusting powders – Effective for treating lice in the mane and tail where liquid treatments are harder to apply thoroughly
• Environmental treatment – Rugs, headcollars, and stable fittings should be treated or replaced to prevent reinfestation from contaminated equipment
