Blowfly Watch
The Blowfly watch in conjunction with Elanco predicts the emergence of blowflies based on Met Office Data. This can help to predict risk of clinical cases and help treatment timings.
The blowfly population is likely now to be at its seasonal maximum in the UK. When very dry conditions dominate, the strike risk is lower because blowfly eggs need a high humidity to hatch. However, as rain becomes more likely and widespread towards the end of summer, the strike risk will increase substantially. The risk is further elevated by regrowth of ewe fleeces and because some of the strike prevention products that were applied early in the year will now be approaching the end of their period of residual protection. As a result, considerable care is required to manage strike as we approach autumn.
