The best way to prevent flies moving from house to house is to treat all houses before the populations start to increase.
Since good fly control is a vital element in controlling potential fungal disease, those farms that drag their feet with control measures could face more problems at a later stage.
Nemasys M is a natural fly control agent which is the most effective and the most popular product of its type on the market in the UK and Ireland. Being a natural product there are many advantages over conventional chemical products including competitive pricing.
