If you’ve left out fruit too long, you’ve probably dealt with small insects fluttering over them. Your first instinct might be to shoo away these pesky creatures. But you’ll notice, they’re quite persistent. Regardless of how often you chase the fruit flies out, they’ll always find their way back to your fruit basket. Your frustration is completely understandable. But we come equipped with solutions. 

Let’s begin with what these insects are, their life cycle, and how they differ from the common house fly. Later, we suggest some of our favorite products keep the fruit flies at bay.

Fruit fly eggs on the wall

Any nook in your kitchen is the ideal place for an insect to breed. The corner provides the right temperature and humidity to harbor new life. Additionally, there are always enough crumbs for the bugs to feed on. But you’re sorely mistaken if you think that leaves the other areas of your house safe from the sheepishly moving fruit flies. 

If you’ve noticed more than usual disturbance on your bedroom wall, we might know who’s to blame. Fruit flies aren’t as quick as houseflies. They tend to make more calculated moves. But their presence in any room might indicate a bigger issue at hand. Fruit flies are attracted to nourishment. They fly towards any place that reeks of ripe fruit and vegetables. While a wall may not exactly be the place where you’d expect the lingering remains of decaying fruit, it’s where you’ll find your adversary. Any spilled drink or morsels of food intrigues these pesky creatures. But more than that, it’s the cracks in the walls that they seek. After they’ve been fed, they seek a place of rest along your walls. Like fruit bats hanging from tree trunks, the fruit flies like to stick around your walls and ceiling.

What can I use to get rid of fruit flies?

Are you tired of your fruit being the target of fruit flies? Have you had enough of the buzzing and the shooing? If so, we’re here to help. We understand it isn’t easy to get rid of such a vast population of insects, but we have a few ways that are sure to hit the bull’s eye.

Here’s all you need to follow:

Maintain cleanliness

Instead of running towards harsh chemicals right away, we’d like to divert your attention toward a much simpler solution. While it may seem like generic advice, ensuring cleanliness is a foolproof plan against any insect. The next time you’re sweeping the floors, make sure to reach into every nook and cranny.

Additionally, maintain a practice of cleaning your fridge every few days. Just because you’ve placed a fruit or vegetable in the fridge doesn’t mean it won’t go bad. Therefore, do a deep cleaning of your refrigerator every other week and throw out any piece that looks rotten.

Sticky tape

If you have no other trick up your sleeve, it’s time to seek the help of DIY gods. Unlike preparing a swan out of origami paper, this DIY is pretty straightforward. Grab a roll of scotch tape and cut medium-sized pieces. Roll the tape, so it’s sticky on all sides. Now, stick the piece onto a wall and wait for the flies to fall into your trap.

Install an electric insect killer

With technology on your side, there’s no battle you can’t win. All you need to do is use the right device at the right time. And there’s no better time to use an electric killing machine than the present. Typically, the insect killer comes equipped with a UV light that attracts the fruit flies towards it. And once they’re close enough to the grid, electric current fries them to bits. It might seem like a harsh end, but this method requires minimum effort from your end.

How to catch fruit flies with an apple cider vinegar trap

fruit flies

When approaching an opponent that has an unfair advantage over you, you can’t be reckless. Before you attack, you need to come up with a strategy that’s guaranteed to work. At the same time, a fruit fly may not seem like too dangerous an opponent. But their ability to reproduce at such an exponential rate makes them ruthless predators.

Begin your attack by luring the flies with a bowl of apple cider vinegar. The vinegar’s scent is like the odor of rotting fruit. As expected, the fruit flies will confuse the vinegar for a potential food source and rush toward it. But before that happens, make sure you’ve lined the bowl with plastic wrap. Afterward, poke a few holes so that they have a way to get inside the bowl but none to escape. Within a few hours, you’ll have a bowl filled with hundreds of fruit flies lying dead in the fermented liquid.

Do fruit flies turn into flies?

A fruit fly may not lead a very eventful life. But within a few weeks, it develops into its adult form. However, it’s often confused with the common house fly due to its appearance. We’re here to ensure these are different creatures with their development cycles. 

Fruit flies don’t transform into house flies. They grow from one phase to another, starting from an egg and ending as an adult fruit fly.  

Fruit vs. house fly

house fly up close

Unless you’re an entomologist, we don’t expect you to know the difference between a fruit fly and a house fly. To some of you, they might as well be the same creatures. It may seem like they’re the same insect at different stages of life. There’s a noticeable difference in size, which makes the previous assumption slightly more believable. However, we’re here to educate you on how a fruit fly differs from a regular fly. We assure you they’re not the same insect, even if they look the part. Here’s how fruit flies differ from house flies:


As long as both the insects are in the air and only in your peripheral vision, they’ll appear the same. But on closer inspection, you’ll realize multiple easily noticeable differences in their shape and form. House flies tend to be darker, whereas fruit flies appear more tan-ish. The pattern of rings around their bodies varies as well. For instance, the house fly has gray stripes all over its face. However, the fruit fly has black rings along the body’s width. 

Additionally, the shape of the two is slightly different as well. House flies are oval with a more rounded outline. However, fruit flies tend to have an elongated oval shape with a thinner outline. You may even notice that fruit flies tend to fly rather drunkenly, which might be because they have a single pair of wings. Alternatively, houseflies have two sets of wings.  


When a house fly hovers over your head, a single glance is enough to conclude its identity. However, you may have to steal a second look with a fruit fly. While many features make a house fly distinct from other insects, their size is one of the most prominent reasons. A typical house fly ranges anywhere from 1/8th to 1/4th of an inch. But when it comes to a fruit fly, you’re unlikely to find anything bigger than 1/8th of an inch.  


Now that the difference between the two insects is much more evident, we’d like to move forward with all the similarities shared by the two. We admit that you weren’t entirely wrong to confuse the two. They do share a common group. Here are all the similarities you may find between a fruit fly and a house fly:

Class and order

Your confusion between the two bugs isn’t completely unwarranted. After all, they belong to the same class. Both fruit flies and house flies fall under the class of ‘Insects.’ As a result, they share certain common characteristics. For instance, both insects have multiple pairs of legs and an exoskeleton that protects their internal organs against damage.  

Furthermore, they belong to the same order as ‘Diptera.’ All creatures under this order have at least one pair of wings, a large head, and compound eyes. 

Health risk

No one is better when it comes to the health risks posed by these creatures. Both insects carry harmful germs that are bound to leave you ill. Since they circle rotting foods, they pick up multiple bacteria and other germs, including E. Coli, salmonella, and listeria.

house fly

You will likely suffer from food poisoning if you consume food infected by these pathogens. In extreme cases, severe water loss, diarrhea, and fever may put you in the hospital. Therefore, ensure your food is safe from all pathogen-carrying insects.

Life cycle

An insect’s life may not be as eventful as ours, but they go through different phases of development just as we do. The cycle begins once the female fruit fly lays an egg. No more than a day later, the egg hatches into a larva.

Life cycle
Instar stage 1Lasts 24 hours
Instar stage 2Lasts 48 hours
Instar stage 3Lasts 48 hours
Pupa formationSkin darkens and gets harder.

Here begins the strenuous process of becoming a fruit fly. The larva undergoes three molting stages known as an instar. Right after hatching, the first instar begins. It lasts about a day and takes the form of a tiny worm. Soon after the first instar, the worm grows in size. It maintains the same shape and structure, but the second instar larva is considerably bigger. Lastly, the larva undergoes two-day development into a third instar larva. Similar to the second instar larva, it maintains its worm-like shape but grows in size. 

After the molting stages have concluded, preparation begins for pupal formation. About 120 hours after the egg laying, a pupa forms. During this stage, the larval skin darkens and transforms into a much harder surface. Essentially, the exoskeleton is formed. Furthermore, the pigmentation of the yes and wings become more apparent. Around day 11, the adult fruit fly emerges from the pupa. This process is known as eclosion, marking the end of a fruit fly’s development.     


In the world of an insect, everything is fast-paced. Within 11 to 12 days, a fruit fly grows from an egg to an adult. And in about 8 to 10 hours, the female adult fruit fly is ready to reproduce. Additionally, the female can lay up to 500 eggs in a mating season. Therefore, you need to contain any such situation before it gets out of hand.   

Where do they come from?

The fruit fly can claim any surface with enough moisture and decay as its home. However, an infestation begins only after an adult fruit fly comes in contact with the rotting organic matter. Either the fruit you brought home was already infested with fruit flies, or you might’ve left a window open. 

Once the fruit fly gets to the fruit, they wait for the decay to settle so they can lay eggs.   

Where do they lay eggs?

The plan of action begins by moving closer to the target. For a fruit fly, the target is decaying organic matter. But that’s not all! Fruit flies can build a population even within drains, garbage disposals, and trash cans. They’re good to go as long as they have a layer of moisture atop fermenting material.  

How to get rid of gnats and fruit flies forever.

Seeing a butterfly flutter its wings inches away from your fingertips is magical. It is fascinating to see a ladybird finding its way out of a grass field. But when it comes to flies, all magic disappears into thin air. If you’re tired of finding ways to get rid of gnats and fruit flies every other week, we might have a few permanent solutions for you. 

Here’s all you need to do to ensure you don’t have to suffer through another episode: 

Keep everything squeaky clean.

The easiest way to eliminate an insect problem is to make your environment inhospitable. Before browsing for expensive traps and chemical solutions, consider a far simpler option. 

Fruit flies and gnats are pesky creatures that are attracted to decaying matter. So all you need to do to get rid of them is ensure all your countertops, nooks, and crannies are squeaky clean. Pay extra attention to your kitchen or store room, as both spots provide the ideal temperature and nutrition for expansive growth.  

Treat with apple cider vinegar.

Vinegar produces the same effect when fermenting fruit and gives off a tangy odor. You can lure fruit flies into a homemade trap with vinegar and plastic wrap. All you need to do is pour apple cider vinegar into a bowl and cover it with plastic wrap. 

Once the bowl is secured, poke tiny holes in the plastic wrap. You can use a toothpick to make the perfect size holes. When the insects come looking for rot in the owl, they’ll be trapped inside, and you can pour the liquid down the drain.  

Get rid of decay

No plan of action is as effective as directly targeting the source. Since fruit flies and gnats look for rotting fruits and vegetables, throw it all out. Keep a regular check on the fresh produce in the fridge. Low temperature may slow down the decay process, but it never completely prevents it.  

Recipe for a homemade repellent

Once the problem gets too out of hand, it’s time to play offense. Prepare a vinegar and soap solution to spray directly onto the pesky creatures. The vinegar attracts the flies toward the solution, and the soap takes them out.  

What do they eat?

Fruit flies don’t have a proper mouth structure to bite and chew. Therefore, they can’t bite into solid foods. As a result, they largely rely on fluids to complete their dietary requirements. Using their straw-like trunks, they suck on juices surrounding decaying material. 

But they adopt a different approach to feeding on solid foods. Fruit flies regurgitate their saliva onto the solid food. The enzymes break down the food particles until it’s completely liquefied. After this, the flies slurp it as they would any other fluid. 

How do they find food?

Insects are not known for their hunting and gathering abilities. They seldom go out in search of food with spears in their hands. However, they do have a sharp sense of smell. Since fruit flies gravitate towards the scent of rot and decay, their antennae are actively looking for any such components. Typically, ammonia or nitrogen-based chemical compounds give food a rotten smell.   

How fast do fruit flies reproduce?

From the point an egg is laid to a fully developed adult, less than two weeks go by. In the meanwhile, an adult female can lay up to 500 eggs. Given their short lifespan, you wouldn’t think they would reproduce at such an astonishing rate.

Do flies throw up when they land?

The animal world is cut-throat, where a predator seeks out its prey for days before finally pouncing on the opportunity to devour it whole. Despite what goes on in the African jungles or the deep sea, insects can be just as ruthless. They might not be vicious to attack, but they have certain qualities that make you want to maintain a safe distance. For instance, did you know they eat their vomit? 

Unlike larger animals, insects lack teeth. As a result of that, they can’t chew or bite food. They’ve to rely solely on their trunk-like nose to slurp fluids. But not all the food they want to consume is liquid. Therefore, evolution provided them with an advantage. Whenever they want to consume solid food, they regurgitate saliva on it. The enzymes in the saliva break down the food, liquefying it. Once the food has completely turned into liquid, the flies slurp it all up!  

Can fruit flies bite?

With insects like mosquitoes circling the block, anyone is warranted to become concerned about insect bites. However, some bugs are all bark and no bite. Fortunately, fruit flies only become a cause of concern when you ingest contaminated food. You don’t have to worry about the flies piercing your skin with a sharp needle-like mouths to suck out blood. Biting is a territory that belongs entirely to a separate group of insects. 

However, irritation and rash are a few common symptoms of a fruit fly interaction. But that’s largely to blame on the multiple germs and larvae a fruit fly carries.    

fruit fly really close

Are fruit flies attracted to light?

How flies make their way to any decaying organic matter is always a mystery. Within moments of the decay, the fruit flies hover over the crime site. As it turns out, they’re attracted to a particular odor emitted by the rotting food. All insects have an in-built sensory system to track food sources far better than any large predator. However, not all insects need to gravitate toward the odor of decay. Certain insects are drawn toward the light, while others may run after particular colors. 

But when it comes to fruit flies, light or photosensitivity barely plays a role. Their primary instinct is to follow their nose and look for any decaying food source nearby. But recent research has observed that even fruit flies show a slight preference towards certain lights. For instance, they tend to fly toward green lights in the morning and late afternoon. These periods represent when the flies are most active. Alternatively, they seek out red light when it’s time to slow down.    


What happens if you eat fly eggs?

Do you like your eggs sunny side up or in an omelet? Whatever your preference is, we doubt you ever want to try insects eggs. More specifically, you’re most likely not on the hunt for fly eggs. However, there’s a chance you might consume some by accident. After all, they’re so small, and there’s no way to tell where they’re with the naked eye. So the bigger thing to consider is what happens after you digest them.

 Fortunately, our bodies are designed to be ruthless toward any unwanted guests. You’ve probably already ingested fly eggs multiple times without realizing it, and the chances are you’ve had to face no consequence. The stomach acid gets rid of any substance that could cause harm. Essentially, the eggs become another source of protein for your body. 

However, there are a few times when things don’t work out so smoothly. You might have to pay a hefty price if the eggs or larvae survive the gastrointestinal tract by some sheer bad luck. Typically, it results in intestinal myiasis. As scary as it sounds, most patients rarely show any symptoms. However, some may experience diarrhea, vomiting, and abdominal pain. 

What’s the lifespan of a fruit fly & how long do they live?

Unlike other animals, insects tend to have a pretty short-lived life. Following the trend of its class, the fruit fly lives no longer than 50 days under optimal conditions. However, they may only survive a week if the temperature gets too hot.  

Why are flies so hard to kill?

You’ve probably noticed that flies have sharp reflexes. You might only think about swatting a fly; somehow, they sense the movement and make a run. The clear reflexes are a result of their superior vision. They have up to 6000 mini lenses in each eye, which slows down real-life movement to an extent. Therefore, they have more time to analyze your activity and make an escape accordingly.  

Are fruit flies harmful & can they make you sick?

On their own, fruit flies tend to be not as harmful. But they’re disease-carrying insects, which makes them a threat. Since they surround rotten foods, they pick up bacteria like E. Coli, salmonella, and listeria. Ingesting any food touched by a fruit fly carries the risk of food poisoning or bacterial infection. Such food may also contain larvae that trigger allergic reactions or intestinal myiasis.   

Does bleach kill fruit flies?

Since they are attracted to any rotten or decaying organic matter, getting rid of the source also ensures their removal. Pouring bleach down a clogged drain helps eliminate the decaying matter, and the low pH kills any insects hovering over it.
