Maggots come from flies, but how do they turn into one? Today, you will learn about the life cycle of maggots and flies.
So, do maggots turn into flies? Yes, maggots turn into flies. Flies lay eggs that turn into maggots. Eventually, the maggots will become adult flies. Once they reach adult stage, they can repeat the cycle all over again.
Maggots have a pretty simple life cycle — from eggs laid by adult flies, they turn into maggots.
As maggots, their parent often leave them with food they can consume as soon as they hatch.
That explains why you can find maggots on spoiled food, rotten fruits, decaying carcasses or even animal wastes.
Maggots need to eat as much as they can from the moment they hatch. They will store the energy they gain from food to prepare for the next stage of their life cycle.
When they have enough energy, they maggots will not seek a dark, hidden place where they can enter their pupation stage.
This is the stage where they will turn into cocoons, the protective layer keeps them safe and hidden from potential predators.
It will take a few days before they can fully transform into an adult fly, but that is basically how maggots turn into flies.
Since we are already at the talk of how maggots turn into flies, let’s discuss everything else in their life cycle.
How maggots turn into flies
There are only “three” stages from the life cycle of flies or maggots. Most of these stages have already been covered up, but here are the full details.
- Larvae stage
- Staying as a larvae
- Preparing for pupation
- Pupation stage
- Slow transformation
- Adult fly stage
- Repeat the cycle
Larvae stage
Before entering the pupation stage, maggots actually undergo through multiple molting periods which is necessary to attain new forms before taking on a “new level” which is becoming a pupa.
How long maggots stay as larvae
Maggots stay in their larvae stage for as long as five to ten days.
When the maggot is born, their first priority is eating in
order to store as much energy as possible to get ready for pupation, the stage
where they transform into adult flies from pupa.
Normally, maggots need to eat for three to five days but it can be longer than
that if they are having difficulty finding food. It happens when they are born
in a place where the food is not enough for hundreds of maggots.
Where maggots go to enter pupation
Once the maggot has already stored enough energy to enter the pupation stage, they will now look for a dark, secluded place that can secure their safety. Usually, a maggot pupa can be found underneath garbage bins or dark unattended corners.
Pupation stage
After finding a safe place away from predators, the maggot will enter and begin the pupation stage after four days. They will then begin their transformation slowly and the process usually takes up to ten days.
What is the life cycle of flies?
As soon as the pupation stage ends, the maggots turned larvae turned pupa can now become adult flies.
Adult fly
When the pupation stage ends, the once maggot is now an adult fly that is also ready to lay its own eggs within two days. This will allow their kind to repeat the same process over and over again, keeping their kind going as the world continues to revolve.
Gestation period
Now that the maggots have become adult flies, they are not able to lay their own eggs. A fly stays pregnant for only 24 hours and the egg also hatches after another 24 hours which makes it easy for flies to keep their numbers up.
Repeating the same process, the adult fly will lay its egg on places where the maggots can easily feed off. Usually, they prefer to lay the eggs on decaying corpses because it provides enough food for hundreds of maggots and lasts for days.
Laying eggs
Most fly eggs are laid in almost any warm, moist material
that will provide food for the larvae (maggots).
The average female fly can lay up to fix or six batches of 75 to 100 eggs and
it normally hatches after 12 to 24 hours. The egg is usually colored gray and
the size is around 4 to 7.5 millimeters long.
What is the life expectancy of maggots and flies?
The life expectancy of the average flies is just about 28
days; some can reach around 30 days for some cases. Without food and water, a
fly can last up to two to three days.
As for maggots, without food, they can also last up to two to three days but
they will die without reaching even reaching the pupation stage.
Most of the time, once a maggot enters the pupation stage, they are expected to
live out the rest of their adult fly’s life expectancy.
What attracts maggots and flies
Since we’re already on the topic about flies and maggots, let’s mention the things they do, what they are attracted to and what they eat. Again, flies lay their eggs on decaying corpses or rotting food so there’s enough food for the maggots to consume once they hatch from the eggs.
Animals like flies and maggots prioritize their
survivability most of the time. There must be a reason why flies keep coming to
your yard.
They must find ways to live and to keep their race going. In other words, they
are attracted to those factors for the sake of surviving the world. It was all
about food, water, shelter and breeding.
Here’s a list of things that attracts flies and maggots.
- Garbage
- Flies usually find food inside garbage bins. They consume food such as fermented fruits, spoiled meat, overripe fruits and vegetables. This is why we must keep the garbage lid closed and shut off properly in order to avoid making flies swarm over the bin.
- Feces
- Flies, almost all kinds of them, consume feces from nearly any kind of animal. This is also the reason why they carry so many bacteria and develop various transmittable diseases.
- Plants
- Certain plants such as mint, sunflowers and daises attract flies for consumption purposes. Flies may also drink from plants and lay their eggs on plants. Sometimes, they just simply land on plants to rest for a while.
- Carcasses
- Consuming carcasses is another way for these flies to fill their stomachs and they also lay their eggs on carcasses so that once the egg hatches, the larvae will have something to feed on the moment they are born.
- Liquid substances
- Spilled soda and juices from fruits can be very inviting for these flies. Not only are they able to hydrate themselves through these consumable liquids, they are also satisfied by the sweet flavor it contains.
- Unattended food
- It is true that they still come near unattended food but without human intervention, they can feast on the food without worry of getting caught by human traps and other animals too. They are opportunistic and therefore, they will take what they can.
- Warm temperatures
- Like other animals and insects, flies are also quite weak against the cold. They thrive better under warm temperatures and thus will seek places that are warm to keep their bodies functioning under normal circumstances.
In the winter, they suspend the activities in their bodies in a way that allows them to survive but some of them usually lay their eggs on winter so the larvae can hatch by spring.
- Like other animals and insects, flies are also quite weak against the cold. They thrive better under warm temperatures and thus will seek places that are warm to keep their bodies functioning under normal circumstances.
- Light sources
- Flies have a natural attraction towards light because of positive phototaxis, the locomotive movement that occurs when a living being moves closer or further away from a light source. This is because most whole organisms benefit from receiving light through photosynthesis.
- Other flies or insects
- The presence of your own kind is a good sign to take that you are welcome at that place. When one fly sees another or even a similar insect, it will make it seem as if they are safe around that area.
Some will also intentionally seek companionship from other flies in order to breed.
- The presence of your own kind is a good sign to take that you are welcome at that place. When one fly sees another or even a similar insect, it will make it seem as if they are safe around that area.
- Unkempt rooms
- An unkempt room near your yard is more likely to have unattended food, unnoticed carcasses or feces of small animals that could have been lurking around the room unknowingly and can be a safe resting place for the flies including their eggs if they are about to lay their eggs.

Are maggots dangerous?
Yes, maggots can be dangerous for your health. They carry numerous bacteria and may develop transmittable diseases. Contact with a maggot can lead to low allergic reactions to high fever attacks.
It can cause diarrhea and symptoms similar to food poisoning such as vomiting and feeling nauseous can also be observed. There is one common infection known that is mainly caused by the maggots, that is “Myiasis”.
Do maggots come out at night?
Maggots can come out anytime, but you would suspect they only come out at night because their eggs cannot be easily seen. Flies lay their eggs and it hatches after 24 hours, so if many of them laid eggs in the morning, there’s a chance they’d show up in the next morning.
