What is blowfly strike?
Blowfly is the primary external parasite that typically affects sheep during late spring and summer. Due to changing weather patterns, the blowfly season has become increasingly unpredictable and prolonged. Blowflies are drawn to lay their eggs on soiled or damaged areas (wounds) on the sheep, as well as on carcasses. Thus, effective blowfly control focuses on minimizing breeding opportunities by:
- Managing deadstock: remove deadstock as quickly as possible, and keep deadstock covered while waiting for collection.
- Managing flock health: minimise faecal soiling through good worm control and fleece management, and through treating wounds, including foot infections.
- Using a preventative treatment early in the season: prevent established blowfly strike in the flock to protect the sheep and to prevent those first waves of flies from breeding. Doing this will massively reduce blowfly numbers, and strike risk, later in the season.
