8 Common Places Where Flies Lay Eggs

Where do flies lay eggs? Flies are one of the most common insects on earth, and they can be found in nearly every corner of the globe. While they come in many different colors and sizes, all flies share one common trait, they lay eggs.

When flies lay eggs this can be a cause for concern, as these eggs can quickly hatch and turn into a fly infestation. When this happens, it can be difficult to get rid of the flies, as they will continue to lay more eggs.

As a result, flies can end up taking over your home or business, contaminating food, and even spreading diseases along the way.

To prevent this from happening, it is important to understand where flies lay their eggs so that you can take steps to prevent them from breeding in your place.

So, below are eight of the most common places where flies lay eggs.

  1. Rotting Meat
  2. In Moist Soil
  3. Animal Nests
  4. Liquid Substances
  5. Feces, Animal Waste
  6. Bottom Of garbage Bins
  7. Dead Decaying Corpses
  8. Over Rip Fruits & Vegetables

8 Common Places Where Flies Lay Eggs

1. Rotting Meat

One of the most common places that flies lay eggs is on rotting meat. This is because flies are attracted to the smell of decaying flesh, and they will lay their eggs in any meat that they can find.

If you have meat that’s starting to go off it’s important to get rid of it as soon as possible. If you do find that flies have already laid their eggs on some of the meat, then it’s important to throw it away immediately.

However, before you do its recommended that you place the meat in a plastic bag first, as this will keep the smell away and hopefully stop any flies from laying eggs on it.

2. In Moist Soil

Flies are attracted to soil for a variety of reasons. The most important factor is that soil provides a perfect environment for fly eggs to hatch. The warm temperatures and high humidity levels allow fly larvae to develop quickly.

Soil also protects fly eggs from predators and the elements and contains a wealth of nutrients that help fly larvae to grow and develop into adult flies.

In addition, flies will also lay eggs in the soil of earthwarms are present, this is so the tiny larvae will also burrow into the soil to look for earthworms to feed on.

3. Animal Nests

Flies are attracted to animal nests for a variety of reasons. The warmth and moisture of the nest provide ideal conditions for the fly eggs to develop. In addition, the feces and other waste products found in animal nests are an ideal food source for fly larvae.

Animal nests are also located in areas that are sheltered from the elements, providing protection from wind, rain, and predators.

As a result, it is not surprising that flies frequently lay their eggs in animal nests. By taking advantage of these ideal conditions, flies are able to increase their chances of survival and reproduction.

4. Liquid Substances

Flies are also drawn to liquid substances. This is because it’s an easy way for the fly larvae to get the nutrients they need to survive especially if they are sweetened.

When flies lay their eggs in liquid substances they are essentially creating a safe haven for their offspring. This strategy helps to ensure that the next generation of flies will be strong and healthy.

In addition, laying eggs in liquid substances helps to keep the flies hidden from view, making it more difficult for predators to find them. So its important to clean up any spill and make sure you rinse out any containers.

The most common type of liquid substances are:

  • Standing Water
  • Fruit Juice
  • Yogurt
  • Syrup
  • Milk

5. Feces, Animal Waste

Amimal feces are always on a flies menu as it smells extremely delicious to flies. Now this may sound gross but feces accally contains a lot of decomposing organic matter and nutriants.

This provides an ideal environment for fly larvae as they feed on decaying organic matter. Also, the high moisture content of feces helps to keep fly larvae hydrated as they grow and develop.

The warmth of the sun also helps to speed up the decomposition process, making it even more attractive to flies. This could explain why you see more flies around feces in the summer months.

6. Bottom Of Garbage Bins

Most of us have experienced the pesky presence of flies near garbage bins and while it may look like they are festing they’re actually there to lay eggs. As it turns out that flies are attracted to the odor of rotting food which provides an ideal food source for fly larva.

Garbage bins are often located in warm and sunny areas, which provides an ideal environment for fly larvae to grow and develop.

The warm temperatures and ample food supply make garbage bins a perfect breeding ground for fly larvae. So be sure to clean your garbage bins regularly to prevent flies from laying eggs in them.

7. Dead Decaying Corpses

Flies are one of the most ubiquitous insects on the planet, and they are known for their unsanitary habits. One of the most repulsive things about flies is that they lay their eggs in dead decaying corpses.

This ensures that their larvae have a ready food source when they hatch. Unfortunately, this also means that flies can spread disease if the carcass is infected with bacteria or viruses.

If you find a fly-infested carcass in a field or on your property, it’s important to have it removed as soon as possible. Otherwise, you risk the flies laying eggs and contaminating the area.

8. Over Ripe Fruits & Vegetables

Another common breeding ground for flies is over ripe fruits and vegetables. As fruits and vegetables start to rot, they release a sweet smell that attracts flies.

The flies then lay their eggs on the surface of the fruit or vegetable, where the larvae can feast on the rotting flesh when they hatch.

However, the fruit need to be well past its date for it to be attractive to a file! So, If you have overripe fruit in your home, it’s best to throw it away rather than let it attract flies.

How Many Eggs Can Flies Lay At A Time?

Flies are notorious for their ability to lay large numbers of eggs. In fact, a female fly can lay up to 500 eggs in her lifetime. The eggs are laid in batches of about 75 to 150 at a time, and each batch hatches within 24 hours.

When conditions are favorable, a single female fly can lay to an entire generation of flies eggs in just two weeks. This high reproductive rate is one of the reasons why flies are such a nuisance.

How Often Do Flies Lay Eggs?

Flies typically lay five or six batches of eggs during their lifetime. However, the number of eggs laid each day depends on the species of fly and the availability of food. For example, a housefly will lay more eggs when there is ample food available than when food is scarce.

On the other hand, a blow fly will only lay a few eggs at a time because its larvae need large amounts of fresh meat to survive. As such, the blow fly will only lay eggs when it finds a suitable carcass for its young.

How Long Do Their Eggs Take To Hatch?

Once the fly has found a good spot, she will lay her eggs on or near a good food source. The eggs are very small and white, and they hatch within 24-48 hours.

The resulting larvae, commonly known as maggots, spend the next 8-10 days feeding on the food source. After they have finished feeding, they pupate, and the cycle repeats itself.

From egg to adult, the entire process takes about 3 weeks. Under ideal conditions, a single fly can theoretically generate an infinite number of offspring.

However, in the real world population growth is limited by factors such as predation and competition for food.

Nevertheless, flies are extremely successful, and their ability to rapidly reproduce has allowed them to thrive in almost every corner of the globe.

How Can You Tell If A Fly Is About To Lay Eggs?

If you find a lone fly buzzing around your fruit bowl or countertop, there’s a good chance it’s about to lay eggs. Female flies are attracted to warm, moist environments where food is readily available – both ideal conditions for the hatching and development of fly larvae.

If a fly is spending more time circling the same spot then that’s a good sign that it’s getting ready to lay eggs. The fly will also start to spend more time in dark, enclosed spaces, as this provides a safe place for the eggs to hatch.

In addition, the fly may also become more aggressive, as it is trying to protect itseggs from potential predators. 

To lay their eggs, female flies will often land on a piece of fruit or other organic matter and use their sharp abdomens to pierce the surface and deposit their eggs just below the surface.

  • Circling The Same Spot
  • Fly Is More Aggressive
  • Spending More time In Enclosed Spaces

If you suspect that a fly has laid eggs in your home, be sure to dispose of any potential food sources right away to prevent the larvae from hatching and developing into adult flies.

How Can You Prevent Flies From Laying Eggs?

Anyone who has ever dealt with a fly infestation knows how annoying and persistent these pests can be. Not only are they a nuisance, but hard to get rid of. Fortunately, there are a few things you can do to prevent these pesky insects from laying eggs in the first place.

Keep Your Home And Kitchen Clean

To prevent flies from laying eggs in your home, it is important to keep both your home and kitchen clean. This means regularly sweeping and mopping your floors, washing dishes right away, cleaning up spills immediately, and taking out the garbage on a regular basis.

You should also make sure to empty any indoor trash cans often and keep them clean. If you have pets, be sure to clean up their food and water bowls regularly as well.

Keep Fruits And Vegetables In The Fridge

Keeping your fruits and vegetables in the fridge will not only make them last longer but will also help to prevent flies from laying eggs on them.

Fruit flies, in particular, are attracted to ripe fruits and vegetables, so it is important to keep them stored away in a cool, dark place. If you have any produce that is starting to go bad, be sure to throw it away right away as well.

Use Fly Traps Or Insecticides

If you have a fly problem that you can’t seem to get under control, you may want to consider using fly traps or insecticides. These products can be found at most hardware stores and can be very effective at getting rid of flies.

One way to stop flies from laying eggs is to use sticky traps. These traps are coated with a substance that is attractive to flies, and the fly becomes stuck when it lands on the trap.

However, if you decided to use pesticides, be sure to read the label carefully and follow all directions.

Wash Your Garbage Bin When Needed

If you have an outdoor garbage bin, it is important to wash it out with soap and water when needed. This will help to prevent flies from being attracted to the bin and laying their eggs there.

You should also make sure to keep your garbage can lid closed as much as possible to further deter flies. Most bin nover days have a lid but if you have an older one, you may want to consider getting a upgrade.


As you can see, there are a few things you can do to prevent flies from laying eggs in your home. By keeping your house clean, using a fly trap, and decluttering often, you can help reduce the risk of an infestation.

However, if you do find flies in your home, be sure to take action right away to prevent them from multiplying.
