Blowflies
Prevention of blowfly strike:

Bodyweight Dose Doses per litre
Up to 25 kg* 20 ml 50
25–40 kg 30 ml 33
Over 40 kg 40 ml 25

*Do not administer to animals of less than 12.5kg bodyweight at the blowfly prevention dose.
Apply as a fan-spray to the surface of the fleece on the back and hindquarters of the sheep using a recommended Crovect applicator gun fitted with a fan spray nozzle. Half the dose should be applied on the shoulders, back and flanks and half to the rump. The distance between the nozzle and the fleece should be approximately 20 cm. Each dose will require 2 or 3 sweeps to apply. THE PRODUCT WILL PREVENT BLOWFLY STRIKE ONLY ON AREAS COVERED BY SPRAY. One application will give 6–8 weeks protection. Re-treat as required.
Treatment of Blowfly Strike
Apply directly to all the affected parts at the rate of 2.5 ml per 100–150 cm2 (roughly the size of a hand). The T-bar nozzle should be used. Most strikes will require 5–10 ml. Ensure that all affected parts are treated. A single application is sufficient to ensure that larvae are expelled and killed within a few hours.

This product contains a blue dye to aid in the identification of treated animals. The colour is temporary and will fade from the fleece within 48 hours of application.
 

 

Contra-indications, warnings, etc

Not to be used in lambs less than 1 week old.
Avoid treating very young lambs if the weather is unseasonably hot.
For the prevention of blowfly strike; do not administer to animals of less than 12.5kg bodyweight.
Take care not to apply in the sheep's eyes. This precaution should be observed particularly when treating breeds with little wool on their heads. 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 by the smell of the tail area.
Operator Warnings
WEAR EYE PROTECTION, PROTECTIVE CLOTHING, RUBBER GLOVES AND BOOTS when applying the product.
WEAR A DUST MASK when applying as a fan-spray for the prevention of blowfly strike.
WASH SPLASHES from skin and eyes immediately. If irritation persists seek medical advice immediately.
DO NOT EAT, DRINK OR SMOKE when using the product.
WASH HANDS AND EXPOSED SKIN before eating, drinking or smoking and after work.
USE IN A WELL-VENTILATED AREA.

Further information

Crovect must be applied only with the recommended applicator gun as the product may have a detrimental effect on certain components of conventional dosing guns. Full operating and maintenance instructions, including details on the use of nozzles, are supplied with each applicator gun. Maintain applicator gun carefully to ensure accurate dosage.
Blowflies are attracted by dirty, damp wool or open wounds. The most common site for flystrike is the rump, due to soiling caused by diarrhoea and urine staining. The efficacy of Crovect is reduced in the presence of soiled and dirty wool. Therefore sheep must be crutched (dagged) regularly and appropriate worm control measures employed.
