Mosquitoes aren’t attracted to lights, this claims it products CO2 to attract mosquito. Every video I’ve watched on youtube that wasn’t a sale pitch stated they almost never find mosquitoes dead in it.
https://mosquitoreviews.com/mosquito-traps/dynatrap/ also states that they find the CO2 claim to be questionable at best. Amazon reviews pretty much state the same thing. All the 1 star reviews state that it kills everything but mosquitoes and the few that it does seem to catch seem to fly away when you go to dump the trap.
It is not water proof and requires you to provide protection from the elements. It must be 5 to 6 feet off the ground to function properly, so you will need a large hanger that also is located in an area with a plug and overhand to prevent rain from getting in.
I hate mosquitoes but it seems fogging treatments and deet sprays are really the only effective way of controlling the mosquitoes population.
So, basically a $90 moth trap.
If you buy this, remember to buy UV bulbs too. They last about 6 months according to the manual and cost $15 to replace via Amazon.
Quote from Mosquitoereviews’s Website on the claim this emits CO2 to attract:
However, when the University of Wisconsin tried to measure the amount of carbon dioxide emitted, they reported that they detected none at all. One reviewer pointed out that the TiO2 surface would need coated with a source of carbon, like dust or dead bugs, in order for the process to make carbon dioxide. See the review here (scroll down to Dr. Marsteller’s comment). The reviewer also commented that the fan would draw in and disperse the carbon dioxide. Actually, that sounds like a benefit, since it would send out signals to mosquitoes farther away, and they would follow the vapor trail to its source. The source would be where the air exits, not up by the ventilation holes, but it would still be close. The big question, though, is whether the trap produces any, or enough, CO2 to make a difference.
The claim that a combination of TiO2 and ultraviolet light produce carbon dioxide is legitimate, since some air cleaners are based on the idea. They use it to remove organic pollutants from the air, and they’ve been tested to work. Their source of carbon is the dust and pollutants, which they turn into carbon dioxide, so a mosquito trap hung outdoors may draw in enough organic dust from the air to work. If the University of Wisconsin tested the trap in a very clean environment, that may explain the complete lack of CO2 emissions. However, even with a source of carbon, there’s still no assurance it produces enough carbon dioxide to be even noticeable to mosquitoes.
