Consumers can choose among several lighting options including tradtional incandescent, compact fluorescent (CFL) and light emitting diode (LED). What is the best choice for your insect trap? What is the best for your porch? A group of Dutch Scientists* compared light trap catches using white LED and white CFL lights of similar quality. The CFL trap caught 3 times more insects than the LED. The conclusions: Use CFLs in your light trap. Use an LED for your porch light or other light when the goal is avoiding nocturnal insects.
Q. Why did the moth go to the psychiatrist’s office?
