Some insects like cockroaches are actually repelled by light. But then on the other hand, we have moths who are always attracted to light. So what’s the science behind a moths attraction to light?
There’s a common phrase that says like a moth to a flame, but why moths are so attracted to light still remains a mystery to us. Here are some theories of why moths could be attracted to light.
Using Light To Navigate 
Some moths actually migrate, and the sky at night can give them a clue to which way they’re meant to go. But because there’s so much artificial light around, it throws off the moths navigational system and they get very confused.
Moths use the light from distant objects to navigate around. So artificial lights confuse them and they become continually drawn towards them.
This theory seems to make sense, but there are a few flaws with it. Remember that artificial light has been around for thousands of years in the form of fire. So wouldn’t natural selection have weeded out this behaviour of moths, to increase their chances of survival? Some scientists have completely debunked this theory, and think there are other reasons why a moth is attracted to light. 
Attraction To Infrared Spectrum 
The infrared spectrum emitted by candle light has been shown to be the same as the one emitted by female moth’s pheromones. This means when a male moth sees candle light, they may be mistaking it for a female to mate with and dive straight into the flame.
This theory is also flawed, because the moths are actually more attracted to the ultraviolet radiations in artificial light.
So all in all, the reason why moths are so attracted to light still remains a mystery. If you or someone you know is having a problem with a moth infestation in the London area, call in Catch-it Pest Control today for moth fumigation services.
