Maggots in a trash can are some of the most disgusting creatures. Do you know how long does it take for maggots to grow in the garbage? Let’s discuss this because next time you are leaving for a holiday, you don’t want to return to see the ugly dustbin crawling with maggots.

These white and creamy squirmy things will fill your mind with a distaste for the whole day. Fly such as houseflies, blowflies, and cheese flies lay their eggs in the contaminated area, which converts into larvae, known as maggots. Some sickening information about them will make you reluctant to use them.

How many eggs can fly lay in garbage?

Female flies can lay up to 500 eggs throughout their entire lifetime, although the lifespan of common houseflies is between 15 and 30 days. Do not wait for them to die. According to the suitable environment for their not-so-cute baby maggots, they can infest their eggs anywhere they find appropriate.


These house flies are attracted to rotten waste, leftover foods, animal dunks, and other bacterial surfaces and lay their eggs in chunks of hundreds. They hatch from the climatic heat in the next 9 to 20 hours and start feeding on what they were laid to grow and reach the next cycle of their lives.

The life cycle of maggots

To understand maggots’ nature and life cycle, we need to look into their life cycle. This will give more light to the life patterns of these creatures, which will help in tackling them.

Flies lay eggs that hatch and larvae emerge from them after twenty days. They feed on dead flesh and meat. Then they move to the next stage of their life cycle, the prepupa, where, after feeding the appropriate amount, they convert into the hard brown shell from which, later on, the adult fly emerges.

This completes the lifecycle. For these creatures to live and multiply, protein is important. It is found in the dead bodies of living beings. The garbage can is the most convenient contaminated spot to lay life in eggs.

Infestation of Maggots in the Garbage

Methane gas produced by microorganisms that break down waste material attracts flies, which are drawn to the gas.

Infestation of maggots

Larvae require a supply of protein, such as leftover meat, in order to develop into healthy maggots, and garbage can be the best source of this protein as well as the finest place for them to do so because rubbish can sometimes contain remnants of food that people throw away.

As we know, larvae feed upon the waste material inside of the garbage can and can be a threat to hygiene if not put into check.

How long does it take for maggots to grow in the garbage? 

Maggots are the first stage of houseflies, and it takes them a while to fully grow into adults after moving through all the life cycle stages.


As we know this unbearable fact, flies lay up to 500 eggs in their entire lifetime, which is about 30 days, but in between, they produce eggs and infest them in the dustbins. Now it is a question of how much time it takes to hatch eggs into fully grown larvae or maggots.

Fly eggs often take about 9 hours to as much as 20 hours to hatch in a warm climate, but if the temperature is 99 degrees Fahrenheit or above, fly eggs can hatch in less than 8 hours.

After continuously feeding on the surroundings, larvae convert into pupae in thirty to forty hours, and pupae manifest into adult flies in 2 to 3 days under the hot climatic temperature.

Prevention of maggots 

I will tell you one interesting story that will shiver your spine with disgust. In 1863, the civil war battle of Gettysberg left uncountable dead bodies of soldiers behind. It is considered the most deadly battle of the civil war and still shivers people’s hearts in rage because of the outcome of that war.

The Gettysburg battle was so severe that a proper funeral was just another wishful thought for the martyrs; their bodies were left in the warzone for days, even weeks, but it was a big feast for some creature that was called Maggot. In between those eras, flies flew like huge clouds and laid eggs inside rotten bodies, which multiplied their population like nothing.

After the war was over, scientists started taking an interest in the creature. As humans, we made solutions to problems and found many ways to harvest them and suck out the advantages for human health advancement.

But the maggots we find in our neighborhood, trash cans, and other waste surfaces are not only dangerous for our health, but these small maggots stick to the domestic pet’s livestock and eat healthy tissue and infect them with viruses and bacterial infections.

Use trash bags: 

In order to prevent flies from laying their eggs in your garbage, you should use trash bags.

Even if eggs are infested in your garbage, they will be unable to escape from the trash bag, and the bin will remain clean until the next time garbage trucks arrive, hand them the garbage bag, and they will be impressed by your sparkling and clean trash can.

Do not dispose of food: 

First and foremost, there should be no food wastage. Freeze the spoiled disposable food and directly give it to the garbage collector when they arrive. Doing this will outrun the fuel for the maggots in the bin and probably die.

How to remove maggots from the garbage?

Get ready with a pair of gloves in your hands because it’s going to get dirty. There is no doubt that maggots are creepy and ugly, but they do not harm you until they get inside of your skin. So do not fear and focus on the following points that I am going to mention to get rid of these squirmy maggots.


The easiest and most effective way to scrape out those little maggots from your dustbin. There are various insecticides on the market that will work on the maggots as they are not especially immune to any kind of chemical.

So any kind of insect-killing chemical will work effectively. Neonicotinoids and Nitroguanidine are two examples of insecticides that can kill maggots in an instance.

Boiling water:

This is the primitive method to destroy insects, specifically maggots, but this method has its own disadvantages.

If boiling water is not poured into all the spots of maggots, then there is a chance that many maggots will still be alive there. The more places there are, the less effective this method will be. So make sure that the bin is empty and the boiling water is poured equally.


Bleach can kill maggots. Bleach contains chemicals such as sodium hypochlorite and sodium chloride (salt), which are harsh on insects and effective in killing them. Take a scoop of bleach and dilute it with one cup of water and pour it on the maggot surface. Rinse it with extra water and let it dry.

Salt, water, lime, or vinegar: 

These four ingredients are solely capable of rinsing the maggots out of their bodies by using them at the effective point of the maggot surface, two to three times to make sure that you have got every last one.

Diatomaceous earth: 

This is a powdered substance that is highly corrosive because it contains tiny silica substances that are highly deadly for exoskeleton creatures.

Maggots are exoskeleton creatures, and if they were sprinkled with this substance, they would die a painful death. When diatomaceous touches insects’ skin, it is destroyed like thousands of tiny blades and razors were thrown at them. 

According to the medical procedures, maggots can cause many diseases indirectly, which can be fatal to anyone, from humans to animals. A large population of these insects increases the risk of myiasis (infestation of maggots into the living tissue).

Can Maggots cause Disease in Human?

According to the various case studies, humans are also not immune to myiasis and can become host to these small maggots.

However, from time to time, various studies on larvae have helped doctors to understand them and tend to their use as a way to improve medical procedures and tactics. Maggots are specially sterilized to be used medically.

They eat the unwanted tissue with bacteria from the patient’s body and prevent the spread of infection to healthy tissues. These are used in various medicine-making procedures, which have improved the quality of the medicinal industry.
