The south west is on high alert for risk of blowfly.

Real-time updates on blowfly risk are produced via an ongoing collaboration between Elanco and NADIS (National Animal Disease Information Service).

They show risk levels as 'High' across much of the UK, including the south west.

Richard Wall, Professor of Zoology (Ectoparasite Specialist) and compiler of the Blowfly Risk Alerts said: "As we know, hot and humid weather creates ideal conditions for strike. Fortunately, the fly population is still relatively small because of the cool conditions in May. That will now start to change quickly.

Strike risk will rise throughout July, spreading across the whole country. In particular, lambs and ewes that remain unsheared will be in jeopardy. We're entering the highest period of risk for blowfly. Being vigilant and prepared is essential."
