Crovect Product Information

Target activity of Crovect

Crovect delivers wide ectoparasite treatment and control in sheep: 

  • treats tick infestation with a persistent efficacy of 10 weeks (the majority of ticks killed within 3 hours)
  • treats and controls headflies 
  • kills biting lice
  • prevents blowfly strike for 6-8 weeks
  • treats sheep struck by flystrike by killing the damaging second and third stage maggots 

Special precautions for use in animals

Crovect minimises mothering-up problems after treatment. However, care must be taken not to apply the product right to the lamb’s tail, as a ewe recognises a young lamb party by the smell of the tail area.

Blowflies are attracted by dirty, damp wool or open wounds. The most common site for fly strike is the rump due to soiling caused by diarrhoea and urine staining. The efficacy of Crovect is reduced in the presence of soiled or dirty wool. Therefore, sheep must be crutched (dagged) regularly and appropriate worm control measures employed.

Take care not to apply product in the sheep’s eyes. This precaution should be observed particularly when treating breeds with little wool on their heads.

For external use only.

Special precautions to be taken by the person administering Crovect to animals

Make sure when attaching the Crovect Pour On gun onto the container that the coiled retainer is secured onto the cap and the applicator.

Wear eye protection, protective clothing, rubber gloves and boots when applying the product.

Wear a disposable face mask when applying as a fan-spray for the prevention of blowfly strike.

Cypermethrin can be skin sensitising and eye irritating. In a few instances, operators may experience a mild tingling sensation of the skin when using the product. Wash splashes from skin immediately and thoroughly with plenty of clean water. If irritation persists, seek medical advice immediately. If product splashes into the eyes, flush thoroughly with water for 10-15 minutes and seek medical advice immediately.

Remove contaminated clothing immediately and wash exposed skin with plenty of clean water.

Do not eat, drink or smoke whilst using the product.

Wash hands and exposed skin before eating, drinking or smoking and after working with recently treated sheep.

Use in a well-ventilated area and avoid inhaling the vapour.

Other precautions

As a precautionary measure, sheep must be kept away from watercourses for at least one hour following treatment.
