How To Keep Flies Off Your Trees

Flies buzzing around your trees can be not only annoying but also damaging to the health of your beloved plants. While chemical insecticides are an option, many people prefer natural and eco-friendly ways to keep flies at bay.

Keep flies off your trees by planting fly-repelling herbs, using natural fly traps, and maintaining a clean garden. Apply citrus and eucalyptus scents strategically and reapply every 3 to 5 days as needed based on weather and fly activity.

In this article, we will explore various techniques and scents that can help you effectively deter flies from your trees, ensuring a pest-free and thriving garden.

What Naturally Keeps Flies Away?

Flies can become quite an annoyance, especially when they’re most active during the warm months. To naturally prevent flies from becoming a problem for your trees and garden, consider the following effective methods:

Planting Fly-Repelling Herbs

An aesthetically pleasing and environmentally friendly solution is to plant herbs with natural fly-repelling properties around your trees.

Herbs like basil, mint, and lavender not only add beauty to your garden but also emit fragrances that most flies find unpleasant. When strategically placed, these herbs act as a natural deterrent.

For example, basil releases a potent aroma that flies dislike, making it a smart choice for planting near your trees or outdoor sitting areas.

In a similar fashion, mint’s refreshing scent and lavender’s calming fragrance create an environment that flies prefer to avoid.

Employing Natural Fly Traps

Another effective approach to managing flies without resorting to chemical solutions is to use homemade fly traps. These traps are straightforward to assemble and highly efficient in attracting and capturing flies.

To create a natural fly trap, take a container or jar and fill it with apple cider vinegar—a substance that flies find irresistible.

Cover the container’s top with plastic wrap, ensuring it’s tightly sealed. To enhance its effectiveness, perforate the plastic wrap with small holes.

Flies will be drawn to the vinegar’s scent but will find themselves trapped within the container, unable to escape. This method is both eco-friendly and practical for reducing fly populations around your trees.

Maintaining a Clean Garden

Flies are naturally drawn to decaying organic matter, which emphasizes the importance of maintaining a clean garden.

Regularly attending to your garden by promptly removing fallen leaves, fruits, and pet waste is essential in discouraging fly breeding. Flies lay their eggs in decomposing organic materials, so a tidy garden eliminates potential breeding sites.

Remember to consistently empty and clean your trash bins, as they can also serve as magnets for flies. By upholding garden cleanliness as a routine, you not only deter flies but also create a healthier environment for your trees and plants.

By incorporating a combination of planting fly-repelling herbs, employing natural fly traps, and maintaining a clean garden, you can significantly diminish fly issues around your trees.

These natural methods not only effectively repel flies but also contribute to a greener and more enjoyable outdoor space.

What Scents Do Flies Hate?

Flies have a remarkable aversion to specific scents, which can be harnessed to effectively keep them away from your trees and garden.

Citrus Scents

Citrus scents, such as those found in lemon and orange, are known to be highly effective fly repellents. You can employ these scents to create a natural fly barrier. 

One simple method is to save citrus peels, like those from oranges or lemons, and place them strategically around your garden. In a similar method, you can use citrus essential oils.

We can spray a few drops of lemon or orange essential oil mixed with water on and around your trees. The refreshing citrus aroma not only enhances the ambiance of your garden but also deters flies from gathering.

Eucalyptus Oil

Eucalyptus oil possesses a robust and distinct scent that flies find repulsive. To use it as a fly deterrent, mix a few drops of eucalyptus oil with water and create a spray solution.

Thoroughly apply this solution on and around your trees. The sharp fragrance of eucalyptus will effectively deter flies from settling in your garden.

Moreover, eucalyptus oil is renowned for its numerous other benefits, making it a versatile addition to your fly control arsenal.


Peppermint oil, with its refreshing and minty aroma, can also be a potent tool in your battle against flies. Dilute peppermint oil with water and apply it by spraying the solution on the leaves of your trees and the surrounding areas.

This creates an environment that flies find unwelcome, helping to keep them at bay. The crisp scent of peppermint not only repels flies but also adds a refreshing touch to your outdoor space.

By utilizing these natural scents that flies hate, you can create a fly-resistant environment for your trees and garden.

Combine these scents into your pest control strategy not only effectively keeps flies away but also adds pleasant fragrances to your outdoor sanctuary.

Where to Use These Scents to Keep Flies Away

Effectively deploying fly-repelling scents in the right locations can significantly boost their efficacy in keeping flies at bay. Here’s how and where to strategically use these scents to create a more fly-resistant environment:

Around Tree Bases

One of the most crucial areas to apply these scents is around the base of your trees. Flies tend to congregate near trees, attracted by the organic matter and foliage.

By generously applying scents and repellents at the tree bases, you create a protective barrier that discourages flies from settling in this area.

This not only safeguards your trees but also prevents flies from using them as a breeding ground.

Outdoor Seating Areas

If you have outdoor seating areas, it’s essential to ensure they remain fly-free for your comfort and enjoyment. To achieve this, consider spraying or using scents strategically around these areas.

The inviting scent will not only deter flies but also provide you and your guests with a pleasant and relaxing space.

Whether it’s a patio, garden bench, or picnic area, incorporating fly-repelling scents ensures a peaceful outdoor experience.

Near Trash Bins

Flies are naturally drawn to trash bins, as they often contain food scraps and other enticing odors. To prevent flies from swarming around your trash bins, place scents and repellents nearby.

This additional measure acts as a deterrent, reducing the likelihood of flies infiltrating your waste disposal areas. By keeping flies away from your trash bins, you maintain cleanliness and minimize potential fly breeding sites.

By strategically using these fly-repelling scents around your trees, outdoor seating areas, and near trash bins, you create a comprehensive defense against flies.

This ensures a more enjoyable and pest-free outdoor environment for you, your trees, and your guests.

How Often Should I Reapply Scents and Repellents?

Maintaining the consistent effectiveness of scents and repellents in repelling flies involves careful consideration of various factors, including weather conditions and fly activity levels.

Here’s a more detailed explanation of when and how often to reapply these essential components of your fly control strategy:

Weather Conditions

Weather plays a pivotal role in the longevity of scents and repellents, affecting how often you need to reapply them:

Rain: After heavy rainfall, scents and repellents can become diluted or washed away. It’s advisable to reapply them promptly to maintain protection against flies.

Wind: Strong winds can disperse scents, reducing their effectiveness. If you live in a windy area, consider using more concentrated solutions or physical barriers to prevent rapid dissipation.

Temperature: High temperatures can cause scents to evaporate more quickly. In hot climates, be prepared to reapply scents and repellents more frequently to counteract this.

Fly Activity Levels

Monitoring the level of fly activity in your garden is crucial for determining reapplication frequency:

Time of Day: Flies are typically most active during the warmest parts of the day, such as mid-morning and early evening. During these times, be vigilant and ready to reapply scents if necessary.

Seasonal Changes: Fly activity often increases during the warmer months. In spring and summer, consider more frequent applications to effectively keep flies at bay.

Garden Inspection

Regularly inspect your garden for signs of fly activity. Pay particular attention to areas where flies tend to congregate, such as tree bases, outdoor seating, and trash bins.

If you notice an uptick in fly presence or activity, it’s a clear signal that it’s time to reapply your chosen scents and repellents.

Time Schedule: To create a practical schedule for reapplication, consider checking your garden for fly activity and the condition of scents and repellents every three to five days during the fly-prone season. Adjust this schedule based on the factors mentioned above.

By staying vigilant and adapting your fly control strategy to weather conditions and fly activity levels, you can effectively manage the reapplication of scents and repellents to maintain a fly-free garden.
