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.
As we progress into Autumn, predicting the remaining blowfly strike risk gets considerably more difficult because of local variations in weather. Blowflies need temperature above 11°C to lay eggs but will die following exposure to lower temperatures – especially frost. At this time of year, daytime temperature are often warm enough for strikes but night time temperatures can be low enough to kill remaining flies. So, the sharp change in temperatures we have seen in September over most of the country means that the risk is now certainly considerably lower – but cannot yet be totally ignored as some strikes could potentially occur on warmer autumn days going into October.
