I recently took a bit of gamble on ebay and bought a Photocatalytic mosquito trap. I was a bit sceptical of these actually working, but to my surprise it does. These traps work by doing a couple of things:
- A photocatalytic reaction the produces carbon monoxide (an attractant)
- A UV light that also attracts the mosquitos
- A fan that sucks them in and then dehyrdates them.
These operate on the principle of Titanium Dioxide (TiO2) creating carbon dioxide when exposed to ultra violet light. Interestingly, the process of creating CO2 happens when the reactive electrons given off, combine with VOCs in the air, so essentially you're purifying your air as well as killing the mosquitos. Theres is then a large fan in the base of the unit that sucks the bugs in an keeps them in the bottom containtment area, where they gradually dry out and die, so no zapping sound or fried bug smell. So far its been quite selective in what it catches, only attracting moths, mosquitos, and other small leaf eating bugs, even after running it during the day.
So far we've been averaging ten or so mosquitos a night (I've only ever seen one or two a day in the past in our backyard)
So if you're unsure of these and are wondering if they work, they do!
