As light-emitting diode (LED) insect light traps (ILTs) become increasingly prevalent, there’s a common misconception regarding their effectiveness compared to traditional fluorescent ILTs. While it’s true that LED ILTs are not as visually bright as their fluorescent counterparts, this does not diminish their efficacy in filth fly monitoring or control. The key lies in understanding the spectrum of light emitted.

LED ILTs are specifically designed to emit light within the spectrum that is most attractive to filth flies. Although this narrow range may appear less bright to human eyes, it is highly appealing to flies.
