Plagues of flies?????

we are planning to emigrate from the uk to Spain but are concerned about horror stories of plagues of flies. How true are they? where should we consider buying/avoiding. We seem to like the Murcia region and as we are 60 and a little disabled we would like views (mountain rather than sea) we want to avoid Brits eating egg and chips, but rather assimilate with Spanish way of life.

about one hour from RMU???

thanks for your advice
