The first cases of blowfly strike in 2019 have been reported in several locations in the UK.
Glamorgan saw the first reported case, with several more reports coming in from Somerset, Lincolnshire, Dorset and Caernarfonshire.
Kate Heller, technical vet at Elanco, says: “Blowfly seasonhas arrived, with multiple reports in quick succession.”
She adds it is import not to ignore the issue, with the cost of blowfly strike outweighing the costs of protection.
She says monitoring alone is not ‘an effective strategy’.
“By the time symptoms show themselves it is often too late.
“It is easy to overlook even one struck sheep and blowfly strike can cause huge damage in very little time.
“Additionally, using protection early reduces risk later in the season by ensuring a much lower fly count as the season progresses.”
When farmers are looking at treatment options, Ms Heller says they should look for the longest protection with an insect growth regulator which binds to the fleece.
