The common housefly is one of the more annoying insects we have to deal with. Not only can they be a real party-pooper (more on that later) at an outdoor picnic, but they always find a way to sneak into our homes and bother us indoors, too. Often we find ourselves batting them away from our food. But what actually happens when a fly lands on our food? The answer is, well, difficult to stomach.
What Happens When A Fly Lands On Your Food
We’ve all been there. You’re attempting to enjoy patio season when a fly keeps on buzzing by your food. Everyone leaves unattended food at a barbecue only to come back to find it covered in insects. You’re trying to enjoy a bowl of popcorn while you watch a movie at night and a fly keeps five-bombing your head.
Most of us will just swat the pest away and continue eating. After all, it’s just a tiny fly, right? It wasn’t on the food very long, so how bad could it be? Well, we’re here to inform you that the answer is worse than you think. In fact, it’s really quite gross.
If you have a weak stomach and want to keep living in blissful ignorance, we suggest you stop reading here. Otherwise, these are exactly the reasons why you may want to consider integrating more fly protection at your next picnic and avoid eating food that they come in contact with.
Flies are very small, so it’s hard to get a look at their faces. If you assumed that this tiny insect eats with a regular mouth, you are unfortunately incorrect. Flies don’t have teeth. Instead, they have a tiny suction-tube-like trunk that they use to slurp food up. The issue is that not all food they like to eat – which is mostly everything – is a liquid. (1)
In order to eat solid foods, they need to turn them into a liquid format. They do this by vomiting up saliva onto it. This saliva turns the solid food into a liquid which they can then suck through their trunk. When you eat food that flies have been on, you’re getting an extra seasoning that you didn’t ask for – Fly vomit.
