Very powerful and effective, the UV fluorescent bulbs have the well-known advantages (attract all insects) and disadvantages (reduced lifespan, requires great caution in exposure, especially to the eyes)

By turning off the lights, you know that they will not approach you and all insects automatically go into the device...
What can I tell you, we're talking about insect genocide.
First, second, and third day, it's literally WAR, and on the fourth day, PEACE☮️, there was nothing left...

It makes a bit more noise than I would like...
I would choose one with fewer watts and lower noise only if I knew it was equally effective, as I use it outdoors and some with fewer watts than what I had read in other reviews are not as effective.
