cluster flies

 “If you followed a fly for a day you wouldn’t eat for a week” is favourite saying of staff at Cleankill Pest Control.

There are more than 110,000 species of flies with the largest being around 6cms long and the smallest only around 0.15mm long. Some are more bothersome than others – depending on the season – and some carry more germs than others.

If staff in top-floor offices are complaining about flies – or your loft space is overrun with insects – it’s probably cluster flies.
