Description

WSD Closantel Sheep Drench

WSD Closantel Sheep Drench is a targeted treatment for internal parasites in sheep and lambs, offering sustained protection against barber’s pole worm, liver fluke, and nasal bot. With Closantel as the active ingredient, this drench provides extended control over parasite reinfestation, helping reduce production losses and support animal health. If you’re dealing with pale gums, bottle-jaw, or low stamina in your flock, this product may help address the underlying causes of anaemia in livestock caused by parasite burdens like Haemonchus contortus.

Why choose WSD Closantel?

• Long-acting protection – Offers up to 4 weeks of control against barber’s pole worm reinfestation.
• Controls multiple parasites – Active against Haemonchus contortus (barber’s pole worm), Fasciola hepatica (liver fluke), and Oestrus ovis (nasal bot).
• Supports strategic worm management – Ideal during known outbreaks or as part of a seasonal parasite control program.
• Complementary to pasture rotation – Especially effective when combined with paddock spelling and other preventative strategies.

How does it work?

Closantel is a medium spectrum anthelmintic that disrupts parasite energy metabolism, killing both immature and mature stages. This makes it particularly useful in the management of barber’s pole worm infestations, which are known for their rapid blood-feeding and high risk of anaemia and death if untreated.
