Product Description
WSD SPURT is a treatment for body lice of sheep.

Type of Preparation
WSD SPURT is a pour-on formulation for topical use containing 25g/L cypermethrin- a synthetic pyrethroid insecticideand a scourable dye.

Sheep and Lambs:
Control of biting lice (Bovicola ovis) in sheep off-shears
Milking Sheep: Do NOT use in sheep producing milk for human consumption

Always refer to the label. Applied at a dose rate of 1ml/5Kg body weight. The correct dose for the weight range of sheep
should be applied as a single continuous strip 20-40cm in length down the middle of the back within 24 hours of
It is recommended that treated sheep be held together in the yards for 2 hours after treatments and not be let straight
out of the race into the paddock.

Advice On Use
- WSD SPURT is applied undiluted.
- It must not be stored in any container other than the original including overnight. Do not leave WSD SPURT containers
uncovered or in direct sunlight.
- It is critical that sheep be cleanly shorn without residual clumps or tufts of wool and WSD SPURT must be applied
less than 24 hours after shearing to ensure effectiveness.
- Correct application is critical and it should not be applied as a single spot or to sheep which are wet.
- Light to moderate rainfall soon after application should not reduce efficacy.
- A clean muster and single shearing with immediate correct treatment of every animal is ideal for achieving effective
control of lice.
- Lambs at foot cannot be treated, and therefore it is recommended that ewes due to lamb within 6 weeks or ewes with
lambs at foot should not be treated with WSD SPURT.
- If a split shearing is inevitable it is critical that treated and untreated sheep be kept separate.
- The repeated use of any synthetic pyrethroid is likely to result in the emergence of resistance in sheep lice. It is
therefore recommended to regularly alternate treatment with a dip such as WSD FLOCKMASTER MKII.
- Resistance to synthetic pyrethroids is present in some populations of sheep lice, and treatment failures may be due to
resistant lice being present.
