Have had a light mosquito season this year, but this has picked up whatever came at it.  Cleaning is easier than any similar item I have had.  Undo a couple screws and wipe it down.  Easy to put back together.  Snags plenty of moths too, won't miss them much.  I have tried several similar devices and this has been the most effective and easiest to clean so far.  It has lasted through one summer so far, hoping it will keep going for some time.  Has kept my back yard pretty clear of the pests since I installed it, and that is saying something.  Usually get bit 2 or 3 times walking to my car.
