How Do Scented Candles Work When Repelling Flies?


Scented candles work as a means of repelling flies by utilizing specific fragrances that flies find unpleasant or overwhelming.

The process of repelling flies with scented smoke and candles can be explained as follows:

Masking Attractive Scents

This disorientation can discourage flies from remaining in the vicinity of burn candles and drive them away.

Repelling Scents

Some scents have inherent properties that flies find repulsive or irritating. These scents can act as natural, fly traps or repellents, causing flies to avoid the area altogether. When scented plants or candles release these specific fragrances, they create a barrier that flies are reluctant to cross, effectively keeping the flies away from them away.

How to Use Scented Candles Effectively

Scented candles not only create a cozy and inviting atmosphere but also offer various benefits, including their ability to repel flies and other unwanted insects. To make the most of scented candles and maximize their effectiveness, follow these simple tips:

1. Choose the Right Scents

Select scented candles with fragrances known for repelling flies. Citronella, eucalyptus, peppermint, lavender, and lemongrass are popular choices. These scents are unpleasant to flies and help keep them away.

2. Position the Candles Strategically

Place the scented candles in areas where flies are commonly found or where you want to create a fly-free zone. Focus on entry points such as windows, doors, and outdoor seating areas. By positioning the candles near these areas, you can create a barrier that flies are less likely to cross.

3. Consider Candle Type and Size

Choose the right candle type and size based on your needs and preferences. Jar candles, pillar candles, and votives all work effectively. Consider the size of the area you want to protect from flies. For larger spaces, opt for multiple candles or larger-sized candles to increase the coverage.

4. Protect Candles from Wind

Strong winds can diminish the effectiveness of scented candles. To prevent the wind from blowing out the flame or dispersing the scent too quickly, use candle holders or lanterns that provide wind protection. This will help the candles burn evenly and release the scents consistently.

5. Trim the Wick

Before lighting the candles, trim the wick to about a quarter of an inch. A shorter wick ensures a clean and steady burn, allowing the candle to release its scent more efficiently. Trimming the wick also helps prevent soot buildup and prolongs the candle’s lifespan.

6. Burn the Candles for an Adequate Time

For scented candles to effectively repel flies, they need time to release the fragrance into the surrounding area. Plan to burn the candles for a minimum of one to two hours at a time. This duration allows the scent to disperse and create a stronger deterrent effect against flies.

7. Use Multiple Candles for Larger Areas

If you have a spacious room or an outdoor patio, consider using multiple scented candles placed strategically throughout the area. This approach ensures better coverage and helps maintain a consistent scent barrier against flies.

8. Practice Safety Precautions

Always prioritize safety when using scented candles:

  • Never leave lit candles unattended.
  • Keep candles out of the reach of children and pets.
  • Place candles on heat-resistant surfaces.
  • Extinguish candles before leaving the room or going to sleep.

Candle Quality and Scent Concentration


The quality of the scented candles plays a significant role in their effectiveness against flies. Furthermore, higher-quality candles made with natural ingredients and essential oils tend to have a stronger and longer-lasting scent. Additionally, these candles often contain a higher concentration of the repellent fragrance, allowing them to repel flies for an extended period.

Burning Time

The burning time of scented candles is another crucial factor to consider. As the candle burns, it releases the fragrance into the surrounding area. Additionally, the longer the candle burns, the more time the scent has to disperse and create a deterrent effect against flies.

Scented Candles to Keep Flies Away: Candle Size

The size of the scented candle can also impact how long it repels flies. Larger candles generally have a longer burning time, providing extended protection against flies. Additionally, if you have a larger space to cover, consider using bigger candles or multiple candles strategically placed to ensure adequate coverage.

Scented Candles to Keep Flies Away: Environmental Factors

Environmental conditions can affect how long scented candles repel flies. Factors such as air circulation, temperature, and the presence of other strong odors in the environment can influence the efficacy of the scents emitted by the candles. Additionally, in open spaces with strong wind currents, the scent from the candles may disperse more quickly, reducing the repellent effect on flies.

Scented Candles to Keep Flies Away: Duration of Repellency

Taking into account the factors mentioned above, scented candles can generally repel flies for several hours.

The duration of repellency can vary from candle to candle, but on average, you can expect scented candles to provide a few hours of fly protection. Additionally, it’s important to note that the effectiveness may gradually decrease as the scent dissipates over time.

To maintain a fly-free environment, it is advisable to relight the candles as needed or replace them with fresh ones to ensure a consistent release of the fly-repellent scent.
