How to Get Rid of Grass Flies - Pest Control & Treatment

Trying to enjoy a meal while being bothered by a fly is the worst possible situation. Even though these pests reproduce quickly, one or two flies aren't always a problem. A small infestation of flies can grow into a sizable one very quickly. To assist you in preventing and eliminating flies that are buzzing around your home, we have gathered information.

Why is My Lawn Full of Flies?

Only in environments that are conducive to life do flies persist. This means that there is likely to be food around, and since flies often feed and also reside on decomposing organic matter, this can be a result of your lawn containing one or more of the following:

1. Overgrown Grass

Overgrown grass has nothing to do with food, but flies prefer it because they can breed there. Your yard will quickly turn into a fly hotspot if there is a lot of overgrown grass and decaying material there.

2. Standing Water

Standing water frequently serves as food and serves as another fly breeding ground. In actuality, this typically occurs when there is a puddle in the yard or when the soil is saturated with water following a significant downpour.

Small decorative pools are sometimes built, and while they undoubtedly add a nice touch to the yard, they are a nightmare to deal with when it comes to flies.

3. Compost Bins and Rubbish

By far, the most effective way to draw flies is through decomposing matter. So even if you compost in your yard for the most logical of reasons, flies will still perceive it as food.

Some individuals throw food scraps into their yards when it comes to actual trash. Flies can detect this and won't turn down a meal.

4. Animal Faeces

A lot of people use animal waste as organic fertilizer. Animal manure is great to fly food, and while it is undoubtedly effective, you will undoubtedly draw a swarm to your yard. Modern fertilizers are specially treated to prevent this issue.

Pet waste is an additional issue with animal excrement. If you have a dog (or dogs), it's likely that they relieve themselves in the yard. Flies will undoubtedly be drawn to anything left behind.

5. Outdoor Cooking

Whether it is cooked or not, flies will consume human food. A barbecue will undoubtedly draw flies (and other animals as well), and you can expect them to bother you while you're cooking as well as your guests while they're eating.

Additionally, a dirty grill left outside after the party is over will make an excellent fly bait. To prevent any unwelcome infestations, make sure to clean it up and store it neatly in advance of the next time it's needed.

6. Organic Fertilizers

Synthetic fertilizers have been processed so that they begin releasing nutrients as soon as they contact the soil, which is the main distinction between them and organic fertilizers.

Organic fertilizers do not undergo the same processing as conventional fertilizers, and their onset of breakdown and nutrient release can be delayed. Fly attractors include the more "organic" smell that is frequently present in organic feeds.

How to Get Rid of Flies on My Grass Naturally

There are a few things you can do to discourage flies from coming into your yard and to get rid of them from your lawn, even though it's nearly impossible to keep them out.

1. Mow Your Lawn Regularly

The space between grass blades will remain wide if you frequently mow your lawn. As a result, flies won't have a place to hide and raise their young.

Aerating your lawn twice a year will also aid in preventing flies. Aeration increases lawn growth and has the added benefit of accelerating water drainage. As a result, there is a much lower chance of standing water amassing, which can certainly draw flies to your yard.

2. Cut Back and Tidy Overgrown Areas

If there's a particularly wild area in your yard, make sure to keep it as tidy as possible. Flies thrive in tall grass and bushes.

3. Empty and Replace Stagnant Water

Make sure to regularly clean the water in your pool if you have one in your backyard. The majority of water purification products contain natural insect repellents that will keep flies away. Alternately, periodically swap out the old water for fresh.

I advise emptying and cleaning the pool in advance of your next use if you won't be using it for a while, such as if you're away from home or won't be using it in the winter.

4. Secure Lids on Compost Bins and Rubbish

It can be difficult to keep flies away from compost piles. Some people keep open compost areas where they are completely helpless against flies. Utilizing closed compost bins is an alternative.

Flies, however, frequently invade even closed compost bins because they can squeeze through the smallest of openings.

It is best to pack trash as tightly as you can when moving it. The smell that is released by anything that is decaying inside can be reduced by properly closing trash bags and securing lids.

5. Clear Pet Poop Regularly

To prevent attracting unwelcome flies, I advise routinely cleaning up after your pets when it comes to droppings from animals. Use poop bags and throw away the contents in frequently emptied trash cans.

6. Plant Scented and Aromatic Plants

Ironically, many insects are naturally repelled by things that smell good to us. The most widely used plants as natural fly repellents are those with strong aromas, like lavender, sage, and rosemary.

I advise growing these kinds of plants both in the ground and in attractive pots throughout your yard. In addition to keeping flies away, they also look great, smell great, and serve a culinary function.

7. Make a Homemade Fly Tray

The best fly traps have a mechanism for drawing in flies, keeping them trapped or restrained so they can't escape on their own, and attracting flies.

You can purchase these in most home improvement stores, but you can also make your own version that is easier, less expensive, and just as effective.

Simply fill a bottle with beer, sugar water, honey, or a combination of these ingredients. The sweet scent will draw most insects, including flies, who will then become trapped inside due to their inability to escape.

8. Burn Citronella Candles

When lit in the evening, when these pests are most active, citronella candles can help keep mosquitoes and flies away from your patio area.

For a few hours, the citronella odor will help keep pests away from your outdoor dining table, but it won't permanently deter flies from your yard.

9. Encourage Predators

Keeping natural fly predators nearby is a very effective way to keep flies out of your yard. Birds, frogs, lizards, spiders, and frogs are the most prevalent predators of wild flies.

Frogs and lizards are excellent fly hunters, so you shouldn't shoo them away if you see them. Spiders, on the other hand, are less effective in your yard (compared to inside your home where they can catch flies in their webs).

As many bird species only eat insects, however, birds are the masters of insect hunting. Avoid luring them to your yard by providing an excessive amount of bird food, as this will encourage them to ignore the flies in favor of your food.

Other Methods of Removing Flies from Lawns

In case none of the suggestions from the above list work, here are a few more.

1. Using Insecticides

If applied correctly, insecticides can be very effective. Always read the manufacturer's instructions and check with your local environmental agency if you intend to use insecticides to treat a fly infestation on your own. Many locations have very strict regulations regarding the use of insecticides.

If in doubt, I advise calling in the pros and double-checking their license information to make sure they are authorized to apply insecticides in your yard.

2. Hanging Fly Traps

The best way to get rid of flies is to hang sticky fly traps; since they have an alluring scent, flies can't ignore them. You may hang them from tree limbs if it doesn't detract from the yard's natural beauty.

Can Flies Be Beneficial?

It may surprise you to learn that some fly species are beneficial to gardens. For instance, long-legged flies are insect predators that frequently consume aphids and other small insect larvae, protecting your plants from tiny pests.

Another helpful fly species are hoverflies. Because of their yellow and black markings, they resemble wasps, but they aren't harmful to people or animals. While they also consume aphids and other common insect pests, these flies are pollinators.


Fly populations are always drawn to locations with access to food and suitable breeding grounds. In actuality, these areas are typically overgrown with a lot of animal waste and other naturally decomposing material, which provides flies with a great source of food.

You must keep your yard neat and the grass cut short to reduce the number of flies there. To prevent stagnation, areas with standing water should be cleaned up or entirely drained. Adding natural predators and insecticides should also help keep flies away.

Eliminating anything that might attract flies to eat is the best way to keep them out of the yard. If they lack a reliable food source, flies are very unlikely to colonize an area.


Do Flies Lay Eggs on Grass?

The eggs of some parasitic flies, like cluster flies, are frequently laid on the lawn. House flies generally lay their eggs in moist areas where decay is present, such as trash, feces or grass and garden waste. According to Colorado State University, they will specifically search for an area with a lot of earthworms where their larvae will feed once they hatch.

Do Fly Damage Plants?

Despite the fact that they prefer foods with more calories, like meat, they will eat plants and can certainly harm them. In fact, fly infestations can harm a plant so badly that it is unable to flower again.

How to Get Rid of Lawn Gnats

Between waterings, give the lawn and garden beds more time to completely dry out. Wherever you see gnat swarms, hang gnat traps, and replace the fly paper often. Gnats and other bugs can be kept out of your outdoor spaces by using torches with an electric or flame source. On plants that gnats like, use commercial or homemade gnat spray.

How to Get Rid of Grass Flies Naturally

Cayenne pepper is an excellent natural fly repellent and also deters many other insects. Spray a misting bottle filled with a mixture of one cup of water and one teaspoon of cayenne pepper wherever you see flies. Lemongrass, peppermint, eucalyptus, camphor, and cinnamon are additional all-natural fly deterrents.
