Why Do I Have So Many Flies in My Yard?

The summer is here, and with it comes a lot of flies in your yard. But why are there so many? You might have more than you think!

So why do I have so many flies in my yard? There can be a variety of reasons why you have so many flies in your yard. Flies are common in our yards, and they’re just looking for food. If you see many flies, make sure your compost is getting hot enough, or that something is rotting nearby. It’s also good to remove any standing water from the yard or house, likely attracting more flies.

There are over 100 types of flies that can be found in the US alone, but the most common ones are fruit or vinegar flies. They’re attracted to rotting food or decomposing matter like manure and compost piles. These creatures find what they need when they feed on these organic substances and move around from place to place looking for new sources of food.

Let’s continue on to find out more.

So why do I have flies in my yard?

Due to what we feed the flies that are outside, many people have many flies in their yards and gardens. Even adult flies must eat very little for their size because they ingest so much. They blow into everything, which is why when you open your trash can lid, all of a sudden, there are millions of them around. There will be a high concentration of flies near any rotting food or compost piles since there is plenty for them to eat if you have them available.

There is no need to worry about this increased density, though, because most flies do not cause anything more than general annoyance usually alleviated by your steadfast squoosh-squoosh-killin’ technique as you reduce them one at a time with direct contact between your hand and their little fly head.

If you have too many in your yard, all you need to do is start cleaning up after yourself more often by putting your food scraps into a compost pile instead of the trash can or bag that they go into now. If you accidentally leave something out overnight, like a banana peel or bread crust, then you will have a lot more flies than usual. If you have a compost pile, put the banana peel in there instead of just throwing it away. If you do not have a composter, then this is why there are so many flies in your yard right now and why you need to buy one as soon as possible.

A few other things that can cause a large fly population in your yard are if you have standing water, such as in a dog bowl, birdbath, or rain barrel. If it’s not cleaned out every few days, then this will also attract additional flies that will be blown into the nearby area by the wind due to their slow movement and inability to maneuver effectively.

If you have many flies in your yard, there is no need to worry because they do not hurt anything and will likely disperse with warmer air temperatures. Just use some of the advice listed here, and you should be good to go!

Is it common to have so many flies in my yard?

It is not necessarily normal to have a great number of house flies around your home or yard at any given time, but it can be common if you live in an area that has standing water or you feed them too much. Some people have and use compost piles, which will attract flies as well.

A few things to note are that there are several different types of flies worldwide with varying characteristics, but unless you know your fly type, it’s probably best to call them all just “flies.” All flies do not bite (although many do) nor transmit any diseases to humans, so you do not have to worry about getting any illnesses from them. Most are just annoying because they like the warmer environment of your house or will try to eat some of the food that you leave on your countertop or open.

Flies in your yard can mean a few different things:

  • If you live near a river or lake, you may have flies attracted to the water, as many species do.
  • If there is a large amount of rotting food around or near your house, this will attract flies, which will be carried away wherever the wind goes.
  • Some areas become more prone to fly populations because their trash cans may not all be covered or because some people do not compost and throw away their food scraps.
  • If there is standing water on your property in a birdbath, dog bowl, rain barrel, etc., it will likely be visited by many different species of fly, which will then blow into your house due to the wind.
  • In general, you may have just noticed a few flies and have no idea why.

Do they harm anything besides my patience?

No, most flies hate people, do not harm anything, and will usually move away when the weather warms up. They only become an issue if there’s a large amount of them… try following the advice outlined above, and these flies should go away soon enough!

How to get rid of flies

Luckily, there is not a great deal of work you need to do to get rid of flies from your yard for the most part. The key thing to remember is that they are looking for food, and if you give them none, they will move on to another yard.

You can put a lid over your trash cans, so the flies do not come into contact with open bags of garbage or food waste. You can also feed your dogs inside instead of outside until you get rid of flies in your yard, and make sure their bowls are clean when they finish eating (remember, flies gather around stuff like this). Put your compost inside if you have one, and make sure that your house is clean inside and no food or dishes are left out overnight.

You could also do some landscaping to ensure the wind does not repel flies right into your home as well, although this may take more time than people would like depending on how large of an area they need to cover. You can also get a fly swatter and take care of any flies you encounter on your property, although if there are a lot, don’t stress yourself out.

They may be very annoying, but if you REALLY want to get rid of flies, it is best to leave them alone unless they start feeding on the food you eat or drink. If you compost, cover up your pile for a while until the flies are gone, but do not put your food scraps in there.

If you have standing water near your home, you should also take away or clean it as it will be visited by swarms of flies that will then fly into your house and make their way to other parts of the city due to the lack of obstacles to get in their way.

How to quickly kill flies

If you’re looking for a quick and effective way to kill flies, there are a few options available. One popular choice is commercial scented fly strips, which use powerful chemicals and flies HATE them. Another option is to simply swat flies dead, although this can be messy and isn’t always effective. Finally, fly baits are also available that contain poison that will kill off the flies within a few minutes. Whichever method you choose, make sure to take precautions to protect yourself from the chemicals or poisons used to kill the flies.

Other tips for keeping house flies out of your yard

Below are a few more tips for managing a fly-in-yard situation…

Watch out for the female flies

The average female fly can lay eggs. And lots of them. In fact. she can lay between 500 and 2,000 eggs in her lifetime, which explains why they can be such a problem when you have flies in your yard. In addition, the female housefly generally lays eggs in decaying organic matter, such as garbage or animal feces. As a result, their larvae often hatch in unsanitary conditions and are exposed to various diseases.

Female flies also have a shorter lifespan than male flies, which means they spend less time feeding and more time reproducing. Consequently, they are more likely to transmit diseases to humans and animals. In summary, the female fly is a major problem when you have flies in your yard because she can lay hundreds of eggs and transmit diseases.

Be mindful of what flies eat

Flies might be small, but they can sure pack away a lot of food. In fact, flies consume about three times their body weight every day! So what do flies feed on? Unfortunately, both flies and their larva are happy to feed on a wide variety of things – from dog droppings to dead backyard birds. And as any garbage can tell you, flies also love food scraps. So if you’re trying to avoid flies, it’s important to be mindful of what they’re eating. Otherwise, you might just end up with a house full of them!

Sometimes it’s easier to just repel flies

Let’s face it, flies are a pain. They’re always buzzing around, landing on your food, and generally just being annoying. But there are times when you can’t just kill them or chase them away. If you’re trying to prevent flies from bothering you, there are a few things you can do to deter them. First, try an oscillating fan. The moving air will keep them away from you. If that doesn’t work, you can try hanging up fly strips or using a fly trap. And if all else fails, you can always try wearing a fly swatter as a hat. It’s not the most stylish option, but it will definitely prevent flies from landing on your head!


The key thing to remember is that they are looking for food, and if you give them none, they will move on to another yard. In general, there isn’t much work to be done to remove flies from your property.

To prevent the fly population from growing larger than it needs to be, make sure your compost pile has a lid over it so that flies do not come into contact with open bags of garbage or food waste inside. You can also feed your dogs inside instead of outside until you get rid of the flies and make sure their bowls are clean when they finish eating.

Put all fruit scraps into an indoor composter like Easy Digester, which will increase temperatures within the container and attract more flies. Fly swatters, fly traps, and other methods will not be very effective if there are hundreds or thousands of flies in your yard because they will continue to come back from nearby areas. They may also reappear if you do not take care of the source why they were there in the first place.

If you have standing water near your home, take it away or clean it because swarms of flies will visit it and fly into your house, where they’ll seek out other portions of the city due to the absence of barriers to entry.
