Why do they sit on your food?

Flies are immensely attracted to trash. We, humans, are known to produce large amounts of trash every day. This is what brings these flies in our environment. Once they come into the vicinity of our houses, the distinction between trash and our edibles is not very well known to them.

It is usually seen that flies mistake our food as trash and sit on them. There is a common misconception that flies are looking for rest on our food. They are certainly not; they are either looking to eat your food, contaminate it or impregnate it.

Eating our food:

Flies don’t just sit and take a mouth full bite of our food. This is not how their anatomy works. Their way of eating includes slurping, spitting as well as vomiting. So when they are sitting on your food trying to eat it, they are basically vomiting and spitting everything out and then slurping on it.

Nasty, right? The house fly usually fills its belly by sponging up the liquids on the surface of your food with their mouthparts. It then vomits this liquid mixed with enzymes and sponges it up again. This is their process of consuming food. Since flies are quite fond of rotting food and other items; they carry loads of bacteria on their feet and mouths. Even if a fly is not eating your food, it is either contaminating with deadly bacteria or laying eggs in your food. This is what flies do when they stay on our foods.

But be warned: fly sprays can be slightly toxic to household pets and fish, and should be used in a well-ventilated room.

  • Fly Trap:

Flytraps can be bought online or easily made at home. The easiest and most common one is the inverted bottle trap. Simply cut off the top of a plastic soda bottle, then invert the top and tape it to the edges of the bottle, and leave some sugary syrup or sweet nectary fruits in the bottle. Overnight, flies will be attracted, but they won’t be able to get out, and will likely get trapped. Throw the bottle away after use.
