![]() Application should be within 4-6 weeks of shearing, when wool length retains the chemical for the claimed protection period on the label. Both have a dual action for flystrike and lice. Jetting or pour-ons with a T-bar applicator along the backline and around the breech, preferably with a dual action (fly and lice) combination product.Įxamples of these are Unlock™ Combination, a saturation/jetting product and Unlock™ Pour-On, a backline/breech application. Best practice to prevent flystrike is by saturation methods. Tell-tale signs of flystruck sheep are biting, twisting and irritation from early larval attack, indicating the need to check the whole mob and use a flystrike dressing treatment on affected sheep after cleaning up the struck areas with a shearing handpiece. Shearing, crutching and/or dagging lambs, two-tooths and ewes in the early summer months alleviates the risk of flystrike. This is compounded by the attraction of more flies and sheep not previously treated with a flystrike preventative, dying a painful death. The larvae develop by moulting, with each larval stage aggressively damaging the skin layer and penetrating the tissue. Unchecked, these strikes occur with up to 200 eggs deposited by just one female fly. ![]() Initial strikes mainly occur in the following areas - shoulder strike from the wool grease odour and bacterial action at the skin level, or dag/urine strike around the base of the tail. After mating, females are attracted to the odour of greasy sheep wool, green dags or urine odour on breech wool. Warmer temperatures bring a new generation of flies. ![]() Timing of treatment and correct product application plays an important part in preventing or reducing the damage that flystrike causes and stress to flock owners. Best practice for flystrike prevention and lice controlīy late April, flystrike is likely to occur in most unprotected breeds and classes of sheep.
