Winter housing brings with it many challenges for animal health, including the control of external parasites, namely lice and mites. Last week, I spoke to a number of farmers who already have seen their stock beginning to look itchy.
There seems to be some evidence across the world that lice and mites are now also showing signs of resistance to modern treatments. Talking to Irish vets this could also be the case. However, with different mites and lice responding differently to various treatments, we need to be careful with our next steps.
