A Chinese man invented an anti-mosquito device by attaching a net to a fan and placing a UV light behind it. The mosquitoes are drawn to the light and then get sucked into the net
I'd say bug zappers do the same thing with less electrical needs, but with this you can carry the bag over to your annoying neighbors house and empty it into an open window.
The UV light probably doesn't do much to attract mosquitoes. The big thing is that mosquitoes have given up strong and fast flight for stealthy quiet flight. They really struggle to get around in even a light breeze, which means they're only a problem when there's no wind. This is just an air filter that pulls in the mosquitoes and catches them in a net.
Not new, not catching mosquitos. You can buy UV-lights that will electrically kill the fly or gnat that will fly into it. Same as with this selfmade device shown here it won't catch any mosquitos tho since, as another user already pointed out, those aren't attracted to light, UV or otherwise. Mosquitos are attracted to body heat, sweat, and CO2. Self-built or not, in both cases the device can become problematic for the environment if left outdoors killing flight insects for hours (illegal here)
I mean, the essence of the article kind of backs it up - that day biters are only weakly attracted, but it's an attraction to a wide range of light, not just UV, and the attraction is much less than most insects -- and that conversely, night biters actively avoid it.
I made a similar setup, with the fan sitting over a bucket of fresh water instead of a UV light. It definitely catches mosquitos. Caught much more when I provided a source of CO2 or sat behind the fan myself, but it definitely caught a shit ton of mosquitos looking to lay eggs in the water.
20 years ago I saw a vid of a guy in some swamp state who placed a bigass fan + thin net over his dog kennel. He was getting a *wheelbarrow* of mosquitos every few days to make compost...
If you are claiming light deflects/repels mosquitos, I believe we can disprove that theory in fifteen minutes on any well-lit southern back porch or patio. In five, camping by a lake, with multiple camping lanterns.
Nah you put them in an opaque jar, then leave the jar on a kitchen bench in your workplace or drop it under the chair of someone you don't like if there is anyone.
emphasis on *most* attracted. I'm *most* attracted to the shares of the weekly RHM, but that doesn't mean I'm gonna scroll past dumps on every other day of the week.
CO2 gradients at range, and some species, like most flying insects, are also attracted attracted to UV, but more weakly than most insects. The night-biters tend to be repelled by UV.
They are also attracted by radiant heat, which the motor may produce, but that is an effective lure only at very close range. Most chemical signals that would lure a diverse crowd of mosquitos are all airborne, and would be disrupted by a fan.
It's more likely that the place has a fuck ton of mosquitoes and the fan is just sucking them up. To be a true experiment there should be a control bag with nothing, and one with just a fan, and one with just a light, to see what truly attracts and captures the most mosquitos.
How does a light capture a mosquito? They can only be drawn to it but aren't inclined to stay. And a fan without a net similarly won't capture them. The only two required components are the fan and net with light, and a fan and net without a light, and they should be close enough that they share the same pool of air that contains the mosquitos so it's not location-based either. But not so close that the control benefits from light. Probably should set up pairs of these in multiple locations too.
Controls aren't meant to be a successful experiment, they're meant to control for factors that aren't obvious. Like, maybe the bag itself is an attractant somehow, and you don't know it until you just hang a bare bag and notice that a percentage of your catches aren't because you put a light on it.
It boggles my mind that you're saying "it COULD work!" while there is literally a giant bag of mosquitoes in the vid. Are you implying that they ran around and grabbed individual mosquitoes and shoved them in the bag for this vid?
Heat is just the excitation of particles, making them move faster. IR radiation is one form of radiation, that is both emitted by hot objects, and can heat up objects. "IR heat" is non-standard. One view would be that it's the heat that's caused by IR radiation, although an alternate view could be its the IR radiation coming from things with heat (i.e. excited particles, elevated temperature).
“Heat” is energy contained in vibrating atoms. All objects have heat, and radiate photons, particles of light, based on how much. More heat = more energy = higher-energy photons = higher frequency. We perceive different frequencies as different colors; red is the lowest we can see, violet is highest. There are frequencies above (ultraviolet) and below (infrared) that we can’t see. Roughly “warm” objects, e.g. mammal body heat, are not hot enough for red light, and so radiate infrared.
IR is "infrared radiation", photons (particles of light) that are in a frequency band below that of visible red light.
Heat is the vibration of molecules.
And you can heat up materials (gas, liquids, solids) via IR light. They absorb the IR photons, and start to vibrate more. They will give off IR photons as they cool down.

Turn the fan on oscillate and point it at where you are. Mosquitoes can barely fly in a little wind.
Mosquito dunks (Bti). Adults waste their eggs in a bucket of water that will kill them before hatching.
Dragonfly pond. Dragonflies have a greater hunting success rate than perhaps any other animal known, at nearly 100%. And they nosh mosquitoes.

And flies. Livestock farmers are learning to disperse dragonfly eggs on the farms to reduce fly populations and it works really, really well.

But where there's IR light there's IR radiation and IR heat right?
imguronefive
IR light *is* IR radiation. Light (UV, visible, IR) is radiation. As are radio waves, gamma rays, x-rays, etc., they are all radiation.
IR heating is when materials absorb IR, and get warmer.
