With The Bar-B-Q Season,

soon about to start,

here is a tip that might keep a few uninvited guests away, entomologists suggest changing your outdoor incandescent light bulbs with LED ones, might help keep some of the bugs away, however, make sure you have the right colour: 

Bugs are most drawn to the blue end of the colour spectrum and ultraviolet light in particular. “Incandescent lights have a much broader spectrum of colours that are generated along with much more heat generated, both of which are attractive to many insects,” Webb explains so looking at LEDs, which “do not output much UV light,” Matts says, so it’s possible that switching your bulbs may make a difference. The wavelengths in typical LED household lights “are simply not the wavelengths that are most attractive to insects,” Webb adds, in one study made in 2016, researchers compared different types of light bulbs between July and September in open grassland around sunset (to ensure there was nothing else attracting the bugs). They collected insects in custom-made traps, and found that the worst option for outdoor lighting was traditional incandescent bulbs, which attracted the most bugs. LEDs on the other hand—both “cool‐white” and “warm‐white”—were the least attractive to insects, yellow-hued light bulbs are worth trying, too. “Yellow lights—and red lights—do not attract insect’s as much as regular white lights,” Russell says, image from super bright leds, which also explores the effects of LED lights on insects.
