Sheep producers need to be vigilant about being alert for fly strike after the recent heavy rainfall and floods.

Regular inspections of all mobs is vital.

In Victoria, scouring and dags are the major risk factors for breech strike and there have been a large number of reports of dirty sheep.

Simple management tools to help prevent breech strike include controlling worm burdens by monitoring faecal egg counts and drenching as needed. Crutching and timely shearing can also significantly reduce the likelihood of strike.

Body strike is most likely to occur when sheep have fleece rot or dermatitis. Belly strike is more likely to occur in sheep with footrot. 

Fly strike prevention is always better than a cure for fly strike. In addition to standard management tools, preventative chemical treatment may be considered to help protect sheep.

Wool and meat withholding periods must also be adhered to and considered.
