Flies, those pesky insects that always seem to be buzzing around, are known to be attracted to certain types of light. As a gardening and landscaping expert, I have come across this issue many times, especially when it comes to outdoor lighting. It is fascinating to learn about the specific wavelengths of light that flies find most attractive.
In the literature, it has been extensively documented that flies and other insects are particularly drawn to light in the ultraviolet (UV) range. This phenomenon has been studied for decades, with researchers trying to understand why flies are so strongly attracted to certain wavelengths of light. One such study conducted by Hollingsworth and colleagues in 1968 confirmed this attraction to UV light.
However, it was Thimijan and Pickens in 1973 who made a significant discovery regarding the specific wavelengths that are most attractive to house flies, scientifically known as Musca domestica L. Their research revealed that flies are particularly drawn to light wavelengths between 310 and 370 nm.
This finding has important implications for anyone dealing with flies, whether it be in a garden, backyard, or even indoors. Understanding the specific wavelengths that attract flies can help us in designing effective lighting strategies to minimize their presence and nuisance.
When it comes to outdoor lighting, it is important to be mindful of the types of bulbs we choose. While many traditional incandescent bulbs emit a broad spectrum of light, including UV wavelengths, newer energy-efficient options like LED bulbs can be more selective in the wavelengths they emit. Opting for LED bulbs that do not emit significant amounts of UV light can potentially reduce the attraction of flies to the area.
In my personal experience, I have found that adjusting the lighting around outdoor seating areas can make a noticeable difference in the number of flies buzzing around. By avoiding UV-emitting bulbs and opting for warm white or yellowish light, which is less attractive to flies, I have been able to create a more enjoyable outdoor environment for myself and my clients.
It is also worth mentioning that the intensity of light can play a role in fly attraction. Bright lights, especially those that emit UV wavelengths, tend to be more appealing to flies. Therefore, using lower-intensity lighting options can also help in reducing fly populations in specific areas.
Flies are attracted to light in the ultraviolet range, with wavelengths between 310 and 370 nm being the most appealing to house flies. Understanding this attraction can be beneficial when designing lighting strategies to minimize fly presence. Opting for LED bulbs that do not emit significant amounts of UV light and using lower-intensity lighting options can help create a more fly-free outdoor environment. So, next time you find yourself bothered by flies, consider adjusting your lighting to deter these pesky insects.
