How Do Citronella Candles Work For Flies?
WouterCitronella candles work by emitting a scent that is toxic to flies and other insects. Generally, these candles are effective within a three-foot radius, but they are ineffective when used in larger areas. To use citronella candles effectively, it is important to follow the manufacturers’ instructions, such as lighting the candles outdoors in well-ventilated areas. Some citronella candles contain chemicals that may be harmful to children and the elderly, so you should read the label before using the candles.
In recent studies, citronella candles were shown to have a significant effect on reducing the numbers of biting and sand flies. A single candle reduced the number of sand flies by 15.4% when placed in a 3.3-foot radius. The candles are widely available in retail stores and online. Citronella candles are also known to be effective against mosquitoes, but their effectiveness is limited.
The citronella scent is not the same for all kinds of flies, but it does make it harder for them to feed. When insects don’t have food to feed on, they become less active. Citronella candles and sprays only work if they are burned, so it is best to reapply them every few hours.
Citronella incense is also an effective way to repel flies. Many brands have a special formula that includes citronella oil as the main ingredient. The only downside is that the scent is only released while the candle is burning. Citronella incense also contains other plant-based ingredients that are not toxic.
