Treating weaner and finisher accomodation

We run a 280 sow farrow to finish unit in North Yorkshire. This will be our 4th year of using Biofly. We started to see a rapid increase in the fly population in one of our weaner sheds which we struggled to keep under control with more conventional chemical products.


This brought with it the usual challenges of health and welfare of the pigs, pen hygiene and working conditions for the people working in this building. The pens in this building are frequently washed and disinfected, however, this can be time consuming when they are covered in fly muck.



Once we established a population of Biofly in this building, the flies all but disappeared and we have continued with the same protocol each year which has kept the flies well under control. This has coincided with an improvement in the health of the pigs in this building over the last 2 or 3 years.


We have since introduced Biofly into our finisher accommodation as well which, in a matter of weeks, rapidly brought under control the fly population which was starting to get out of hand. These pens are washed out less frequently, so the fly muck was even more of a challenge when it came to washing out. It’s amazing how much time has been saved washing now that there is significantly less fly muck. A much cleaner pen is also better for animal health and welfare. Less time washing means we can focus more on other areas of the farm.


Biological fly control is very easy and simple in comparison with using chemical control. I would certainly recommend it to anyone that is having fly problems on their farm if you want to save time and improve animal health and welfare.
