Posted by Muzi On 08 Jul, 2020

House flies are an insect that is most often considered as harmless due to it being small in size, however, these tiny insects can spread more illness than any other pest.

According to the World Health Organization, house flies can spread approximately 65 various diseases. They not only contaminate the food and surfaces within your home and office but they also are the main reason for your employee's sicknesses.

As a business affected by flies, you can expect a decline in your staff's health and drastic contamination of your food items and products, all of which will only lead to a bad brand reputation and a lawsuit.

How to Identify House Flies?

House flies are grey and around ¼ inch in length. The most dominant trait in a house fly is their reddish and large eyes. Another physical characteristic is the dark broad stripes that are visible in the middle section of their body.

However, house flies are usually easily distinguished from other flies by the fact that they do not bite due to their unique mouthparts that are used to suck in any liquid. The only type of flies that are likely to bite humans is a horsefly, stable fly, deerfly or blackfly.

Why You Can't Swat a Fly?

Flesh flyAlmost every human has tried to swat a fly at least once in their lifetime and has failed.

Although it doesn't look that hard, it is quite difficult to do so especially due to their eyes, speed and body hair. They can fly at 5 mph that can increase to up to 15 mph when they sense a threat.

It is also their heightened ability to sense the fluctuation in airflow due to their body hair and eyes that allow them to easily escape before getting swatted with a newspaper or other object. Therefore, it is near to impossible to swat a fly.

Which Diseases do They Carry?
