Curious about why wasps are attracted to light bulbs?
Join the discussion to explore this fascinating behavior and share your insights!
Why do wasps like light bulbs? I’ve noticed them buzzing around my porch light all the time. Does anyone know why?
I think it’s because wasps are attracted to light in the same way that moths and other insects are. It’s probably an instinctual behavior.
That’s interesting! I also wonder if the heat from the light bulbs plays a role. Maybe they’re attracted to the warmth as well?
Yeah, many nocturnal insects navigate by using the moonlight, so artificial lights like bulbs can confuse them. Wasps might just be following the same instinct, even if they’re not nocturnal.
Another theory I’ve read is that some insects are attracted to the UV light emitted by bulbs. Not all bulbs emit UV light, but the ones that do might draw in more insects, including wasps.
Has anyone noticed if certain types of light bulbs attract wasps more than others? Like LED versus incandescent?
That’s a good question. I think LEDs are supposed to attract fewer insects overall because they emit less UV light. But I haven’t tested it personally.
I’ve swapped out my incandescent bulbs for LEDs and noticed a significant reduction in insects. But, yeah, an occasional wasp still comes around, especially if there’s another attractant like food nearby.
That’s correct! LEDs are generally less attractive to insects. However, some people still report seeing wasps around LED lights. It could be due to other factors like the color temperature of the light.
I’ve heard that wasps are more active around lights because they hunt other insects that are also attracted to the light. Any truth to that?
Yes, wasps are opportunistic feeders. If there’s a concentration of insects around a light, the wasps will likely be there too, taking advantage of the situation.
That makes sense to me! I’ve seen wasps preying on smaller insects around my garden lights. Maybe they’re just following their food source.
There’s definitely some logic there. Wasps are predators, so if they see other bugs around a light, they might stick around to catch an easy meal.
@wLaurie You’re probably right about the light attracting smaller insects first. The wasps are basically just following their food source.
I’ve noticed the same thing on my porch. The wasps seem to hover right around the bulb, especially in summer evenings. Makes me think they’re just chasing heat and the smaller bugs.
I replaced my regular bulb with a yellow “bug light” and honestly saw fewer wasps hanging around. Not 100% gone, but it helped.
Anyone else tried switching to LEDs? I heard they don’t give off as much UV, so fewer bugs (and wasps) get drawn in.
That’s exactly what I was curious about. I’ve been considering LEDs for the backyard since regular bulbs are like magnets.
I tested citronella candles near my light fixture. They didn’t keep the wasps away entirely but seemed to reduce how long they stayed.
