Flexolt

Flexolt is the new oral lice treatment that gives farmers the flexibility to treat lice when it suits them. This is a product that changes everything.

Oral lice treatment for sheep and lambs*

Flexolt contains the novel active for sheep lice control, fluralaner, which works systemically via oral administration. Simple and effective lice control starts from the inside.

Treat lice in any length of wool

Effective lice control is no longer linked to shearing. Flexolt is effective for unshorn lambs*, short wool, long wool, off-shears and up to 7 days off-shears.

Flexible lice control when it suits you

Flexolt lets you choose when it suits you to treat for lice and allows you to adapt to common challenges to simplify lice control.

*Lambs from 6kg body weight.

Lambs at foot

Lambs* can be treated to ensure a complete program for the flock.

*Lambs from 6kg body weight.

Rainfall delays

Oral lice control is unaffected by rain, so rain events don’t have to dictate the timing of treatment.

Cold weather

Sheep can be treated without cold weather exposure issues common with dipping or jetting.

Poor Shearing

Treatment is not affected by poor shearing that can impact external application.

Long wool outbreaks

Incursion can be treated as soon as lice are noticed at mob level.

Introducing new stock

Purchased sheep can be treated off the truck regardless of wool length*

*Rehydrate sheep after transport before treatment. Sheep will need to be quarantined for a period following treatment.

Split shearing

All sheep on property can be treated at the same time – regardless of differing wool length.

Application Guidelines

• Determine the correct dosage for animals based on weight.
• Dose the mob to the heaviest animal by body weight in each group
• Drafting into two or more lines may be appropriate, to avoid excessive overdosing.
• It is recommended that as sheep are treated, they are marked (with a crayon) so any untreated sheep can be identified and treated.
• Most commonly available drench applicators will be suitable – ensure they are clean and working well and calibrate before use.

• Use a 10mm tube between the backpack and applicator to ensure optimal refill time.
• Rainfall before or after oral treatment will not affect lice control
• Rinse applicator and tubing with water at the end of each day used
