WSD Closantel Sheep Drench 5L | Sustained-Action Worm & Fluke Control - Shop Online

What Farmco Recommends It For:

Farmco recommends WSD Closantel 5L for Australian sheep and lamb producers tackling Barber’s Pole Worm, Liver Fluke, and Nasal Bot infestations across their flocks. It’s ideal for spring drenching programs and broader parasite management strategies on stations and family farms alike.

Why It’s a Farmco Favourite:

This trusted Aussie-made anthelmintic delivers sustained four-week protection against re-infestation while controlling both mature and immature parasite stages — making it a reliable cornerstone of any flock health plan.

Targeted Parasite Control for Aussie Flocks

WSD Closantel 5L tackles three of the most damaging parasites threatening Australian sheep production: Haemonchus contortus (Barber’s Pole Worm), Fasciola hepatica (Liver Fluke from six weeks), and Oestrus ovis (Nasal Bot). Containing 37.5 g/L closantel from the salicylanilide and substituted phenol family, it delivers narrow-spectrum precision with broad-flock benefits.

Four Weeks of Sustained Protection

After dosing, WSD Closantel keeps working — providing four weeks of sustained action against Barber’s Pole Worm re-infestation. It controls both mature and immature stages of Liver Fluke and clears all stages of Nasal Bots, helping reduce production losses and protect liver health right through the season.

Easy Oral Drenching, Trusted Aussie Quality

Manufactured locally by WSD Agribusiness in Western Australia, this 5L pack dispenses at 1 mL per 5 kg bodyweight through standard drenching equipment. Pair it with WSD Levamisole or WSD Combination in a rotational program to slow resistance and keep your flock thriving season after season.
