flies

worldwide, posing a threat to humans and animals because they carry and spread diseases. Common diseases spread by

flies

in the UK are; Salmonella and E Coil. These are carried on their legs and small hairs on their body, so when they land of your food it is transferred onto that surface waiting for you to take a bite. They breed and mature very quickly so a small

tend to be around food and waste.
