Do Flies Poop on Your Food?

If you think of flies as disgusting little pests, you might worry about their proximity to your food while you’re not watching it being prepared in the kitchen. What does a fly do when it lands on your food? Do flies lay eggs on your food? Do flies poop on your food? In this article, we’ll help answer these questions and more.


If you thought flies only landed on your food to lay eggs, you are mistaken. While they do use their ovipositor to deposit their eggs in meat, a fly will also land on your food just for the fun of it. What does a fly do when it lands on your food? It might just be looking for something to eat, but it could also be urinating or depositing fecal matter onto your meal. Gross!

What do flies eat?

What does a fly do when it lands on your food? Well, it’s not going to poop. In fact, flies are attracted to the smell of fresh food and they’re not too discriminating – they’ll land anywhere there’s some kind of tasty-looking morsel (besides your food). They might even land in your glass of water or wine.

 What do flies eat when they land? They’ll either sip out of whatever it is (e.g., water or wine) or take a few little sips and then fly off to something else that smells better. If a fly stays for more than 30 seconds, you should probably start thinking about how you’re going to get rid of it. However, if one walks around your food for a while, don’t panic: it might be looking for an entrance point – like its mouth! So if you notice a fly walking around your food but not eating any of it, it’s just getting ready to poop.

How do they digest their food?

Flies have a particular type of gut called the hindgut, which is also known as the proctodeum. This is where digested food goes after it has been eaten. In this part of the gut, there are microbes which break down food into nutrients and amino acids that can be absorbed by the fly. There are also symbiotic bacteria in this part of the gut that can provide nutrients to the fly.

 Unfortunately, flies are not very hygienic animals, and they don’t always avoid defecating while they’re eating. They will usually leave a pile of their own droppings right next to their food source. Since food is in liquid form when it goes through the hindgut, it’s usually pretty easy for droppings to accidentally end up in a fly’s mouth during feeding and be swallowed. However, flies don’t always intentionally eat their own poop—sometimes droppings will just fall into an open fly’s mouth or even land on its body after it has already eaten some other food.

Where does the poop go?

If you’ve ever seen a fly land and then jump off of your sandwich, you might be curious as to where that fly poop might have gone. Well, if the fly has pooped on your food, it will either go down onto the surface of the food or it could potentially get into your mouth when you take a bite.

The most important thing to do in this scenario is to make sure that any remaining food is cleaned off of the affected area before eating it. In other words, pick up all crumbs and wipe them away with a napkin or paper towel. If there’s visible poop anywhere on the surface of the food (even in tiny specks), it should be wiped away with wet napkins or paper towels before being consumed.

Are there any benefits to having flies around?

It’s a common misconception that flies are attracted to food. In reality, they’re attracted to the smell of decomposing organic matter, which means they could be hovering over your food because something in your kitchen is rotting. But while they may not land on your plate, they will leave behind their poop or larvae, which can lead to food poisoning.

If you’re constantly having problems with flies and you don’t have anything rotting in your house, then it’s likely that there’s a larger issue at hand. Problems with pests like flies are often caused by leaky pipes or windowsills where crumbs are building up and attracting the insects. If this is the case for you, then it might be time to call in an exterminator.

Are there any dangers in having flies around?

No one wants to think about the possibility of flies, bugs, and other insects crawling around their food. But if you don’t want to be paranoid about it, here are a few things to keep in mind.

First off, there’s nothing stopping you from cooking your food before it hits the table and there’s a chance of contamination. Secondly, flies have evolved to be attracted to meat so they’re not going out of their way to find what they’re looking for. And thirdly, while they do have some disease-carrying capabilities such as salmonella and E. coli, most bacteria is killed when exposed to high temperatures that would cook your food anyways.


So, do flies poop on your food? It’s true: they do. And it’s gross. The next time you see a fly buzzing around your sandwich or snack, remember that you might be about to take a big bite of poop. But don’t let that deter you from eating outside—just put down a layer of tinfoil before you start feasting!
