Query: Very large fly trap

It seems to work pretty well as I have some small flies in the trap. Though, keep in mind that the those fly ribbons basically do the same job at much cheaper. The advantage to this is that it works as night since it is lit as well. Keep in mind this thing is pretty large so there is not hiding this thing and you better make sure you have enough clearance for it. It is pretty bright as well so I would not put it anywhere that you need it to be darkened (i.e. living room or bedroom). Overall, happy withe the product.
