Most fly species feed by being sick onto a food source and then sucking up the saliva liquid that they have vomited up. This inturn contaminates the food source with bacterias from the flies feet and stomach. This can be the cause of deadly diseases such as food poisoning, typhoid, cholera and dysentery. Hygiene is key when it comes to fly species and in food premises or heavily affected areas there are many preventative precautions that we can put in place to combat fly activity.

A single bluebottle can lay up to 600 eggs which are capable of developing into maggots in 48 hours and mature bluebottles in one week. Like other fly species blue bottles are found on rotting food, animal and human waste matter, dustbin areas and dead carcasses.

They then move off of these areas where they will carry their bacteria when they land on food sources. Cluster flies can be found in very large numbers when they fly to high roof spaces and higher rooms in houses in autumn to hibernate. They then re-emerge in spring to lay their eggs. These flies can cause considerable distress due to their large numbers and characteristic smell as well as their lazy flight patterns around a property.
