Yeah Netting off is the only solution or getting your neighbours to stop spraying pig and chicken slurry on their land, which incidently is illegal, if they spray manure it has to be turned into the soil immediately which non of them do of course!! ::)

Hmm I done some research on this illegal spraying of manure and slurry, I could bore you with it complexities but suffice to say the European Legislation is complex affects different locations in different ways requires certain good practices to be employed when local conditions and balances are met.

To say manure has to be turned into the soil immediately would be correct in only a small occurences when local conditions , climate, time of year , soil type, chemical compostion of soil would pose risk to health and flora/fauna and water contamination.

The EU regulations focus on reducing over fertilzation, correct safe storage of slurry/manure and its best application to prevent pollution to flora fauna and water table contamination, therefore as we all know there is a law for just about everything in the EU but its loaded with caveats

They emphasis is on education of farmers getting the balance right for sustainable farming and helping the farmers avoid costly civil proceedings  when the storage and spreading of slurry and manure  goes wrong and has environmental repercussions .

So I very much doubt  that our Spanish Farmers are breaking EU laws.  :)

By the way during my research it became very apparent that the Lawmakers  were working closely with farmers to get this right as there has been a European if not worldwide return to utilising manure and slurry as it is a lot cheaper than man made fertilizer . Bringing  technoglogy together with manure and slurry isnt as simple as you would think ;D

PS I didnt find any mention of flies in the papers I researched
