Coopers Maverick | Sheep Lice & Worm Treatment
Treat sheep lice and worms in one handling event.
Learn how Coopers Maverick combines lice treatment and abamectin-sensitive worm control in one rainfast pour-on application.
Product Overview
Coopers Maverick is an off-shears pour-on treatment designed to control sheep lice and abamectin-sensitive gastrointestinal worms in a single application. Applied within 24 hours of shearing, Maverick reduces labour, simplifies chemical management, and minimises additional sheep handling.
Unlike standard lice-only pour-ons, Maverick combines lice treatment and worm control in one pass through the shed, helping producers reduce handling stress and save time during shearing operations.
Why Producers Choose Coopers Maverick
Combined Lice and Worm Treatment
Maverick combines abamectin pour-on lice control with treatment of abamectin-sensitive gastrointestinal worms in one application.
This allows producers to:
- Reduce handling time
- Eliminate a second handler pass
- Simplify NVD record keeping
- Reduce labour costs
- Minimise sheep stress during shearing
The Case for Combining Lice and Worm Treatment
| WITHOUT MAVERICK | WITH MAVERICK |
|---|---|
| Two separate products to buy, store and account for on the NVD | One product, one storage location, one NVD entry |
| Two separate shed events or handler passes | Single handler pass |
| Additional labour costs from second handling | Significant labour savings |
| Higher combined treatment costs | Often cheaper than separate treatments |
| Increased sheep stress from extra handling | Reduced handling stress |
When Maverick Is the Right Choice
1. You Already Drench at Shearing
If abamectin is part of your worm rotation program, Maverick replaces both your lice product and worm drench in a single pour-on treatment.
2. Large Commercial Sheep Operations
For larger mobs, removing a second handler pass can save substantial labour during shearing events.
3. Simplified Chemical Management
Maverick reduces the number of products that need to be ordered, stored, and tracked.
4. Levamisole or Benzimidazole Resistant Worms
Maverick treats abamectin-sensitive worm strains, including some resistant to levamisole and benzimidazoles.
5. Rainfast Lice Treatment
The water-based rainfast formulation maintains treatment efficacy even if rain follows application.
6. Suitable for Adult Sheep and Weaners
Approved for sheep over 6 weeks of age and at least 10 kg liveweight.
Critical Application Requirement
Maverick MUST Be Applied Within 24 Hours of Shearing
This is the most important requirement when using Maverick.
Unlike many other lice treatments that allow up to 7 days post-shearing, Maverick depends on application before wool regrowth begins.
If treatment is delayed beyond 24 hours after shearing, lice control efficacy may be compromised.
