CLiK POUR-ON is a water-based, ready-to-use, pour-on formulation, containing 5% w/v dicyclanil.


Prevention of blowfly strike due to Lucilia sericata on sheep.
Prevention of blowfly strike due to Wohlfahrtia magnifica on sheep.

Dosage and administration

For external use only.
CLiK is applied according to the following recommendations:

Sheep weight (kg) Total volume/ sheep (ml) No. doses per 2.2L pack No. doses per 5L pack
10-20 20 110 250
21-30 25 88 200
31-50 30 73 166
>50 35 62 142

(Guide dose volumes correspond to 0.6 - 2 ml (30 - 100 mg dicyclanil) per kg bodyweight.)
Shake the container well before use.
CLiK must be applied with a manual or automatic dosing gun (e.g. Novartis Pour-on gun), with a spray nozzle, which will ensure the correct spreading of the product on the fleece. Best results will be achieved by holding the gun approximately 45 cm from the sheep during application. Apply as a fan spray along the spine of the animal in a band at least 10 cm wide from the middle of the shoulders and in an arc around the crutch and tail. Half the dose should be applied along the spine with the remainder over the tail and crutch area.
CLiK is administered once, before predicted Wohlfahrtia fly activity, or before or at the beginning of Lucillia fly activity. CLiK will protect against blowfly strike caused by Wohlfahrtia or Lucillia flies for 16 weeks. In individual cases, a strike may occur earlier; therefore, it is good practice to check animals regularly for blowfly strike.
Do not shear sheep in the 3 months after treatment.
Special Precautions for use in animals
The product is best applied before an anticipated blowfly challenge, or when a blowfly challenge is identified on or in the vicinity of the farm. Established strikes may require a separate treatment with a knockdown insecticide.
It is recommended that animals with dirty back-ends are dagged prior to application. If dagging or crutching is undertaken in the weeks following application, these animals should be re-treated, otherwise protection could be lost.
Do not apply during heavy rainfall, or when such conditions are expected, as the resulting wash-out may reduce the protection period.
The use of CLiK has harmful effects on dung flies.
Treated sheep must be kept away from watercourses for at least one hour after treatment. There is a serious risk to aquatic life if this advice is not followed.

I have been using this for my sheep for 4 years now and never had a case of flystrike. I use it in the late Spring and again in Autumn. Really trust that this works.
