CLiK™ Spray-On Sheep Blowfly Treatment (dicyclanil)

Put the worry of blowfly strike behind you

CLiK™ Spray-On has long been the mainstay fly control product for Australian sheep producers, providing season-long protection against fly strike for 18-24 weeks.  CLiK™ Spray-On has the unique added benefit of Rain Lock™, the result of formulation technology that allows the active to resist wash out offering peace of mind for sheep producers, even in the face of wet weather.*

CLiK™ Spray-On is registered for the protection of sheep, either off-shears or with any length wool, against fly strike (caused by dicyclanil-susceptible strains of blowflies (Lucilia cuprina)) for 18 to 24 weeks. It is also registered for the protection of mulesing and marking wounds on sheep against fly strike (caused by dicyclanil-susceptible strains of blowflies (Lucilia cuprina)) during the wound healing process. CLiK™ offers the following key benefits:

  • Season long protection against flystrike for 18-24 weeks on all breeds of sheep with any length wool
  • Potent insect growth regulator that breaks the life cycle of the blowfly before any damage occurs
  • Rain Lock™ formulation technology that enables CLiK™ to bind strongly to wool fibres to resist washout 
  • Convenient ready to use spray on formulation

The Hidden Costs of Flystrike

The prevention and control of blowfly strike caused by Lucilia cuprina is a vital component of sheep husbandry and welfare in Australia. Flystrike is estimated to cost the Australian sheep industry a reported $173 million per annum.1 Historically, it has been estimated that some 3 million sheep died each year as a consequence of flystrike.2 While mortality is a significant cost and worry for sheep producers; there are other less obvious impacts of flystrike. These include reduced sheep fertility, lost meat and wool production, damage to skins, and the cost of chemicals and labour for treating struck sheep. Strategic preventative treatment of sheep early in the season has been proven to reduce fly population build-up3 and consequently reduce the impact of blowfly strike on productivity. CLiK™ is ideally suited for this purpose.4

Important Safety Information

Prior to use, please consult the product label for complete instructions. May irritate the eyes and skin. Avoid contact with eyes and skin. When opening the container and using the product, wear elbow-length rubber gloves. Wash hands after use. After treatment, wait until sheep are dry before rehandling.

Withholding Periods

MILK: DO NOT USE on sheep that are producing or may in the future produce milk that may be used or processed for human consumption.

WOOL: DO NOT USE less than 3 months before shearing or fibre collection.

Use of this product may result in wool residues that may not comply with European Union environmental quality standards. Wool treated with this product may contain detectable residues; adequate treatment records should be kept and made available, if requested by wool buyers.

MEAT: DO NOT USE less than 28 days before slaughter for human consumption.

Export Slaughter Interval

DO NOT USE less than 9 weeks before slaughter for export.

Directions For Use

DO NOT re-treat animals for a minimum of 9 weeks after last treatment.

DO NOT dilute.

DO NOT mix with any other product.

DO NOT apply during gusty or windy weather as spray drift may reduce the period of protection. It is good agricultural practice for mulesing/marking to be carried out at times of minimal fly activity. Reduced efficacy may occur in sheep affected with dermatophilosis. Significant soiling with dags, mud, dust or urine may reduce efficacy. Where significant dags are present, a light crutching is indicated prior to treatment. Protection period may be reduced if sheep scour heavily following application.
