This trap does catch some small flying bugs, but not the bitting flys as what is marketed for. I bought 2 of these, put one in front of my house and the other in the backyard. The front one hasn’t caught any bugs whatsoever, and I counted 8 bugs total in the backyard trap so far. I hanged the traps about 2 to 3 weeks ago, so I would have expected to see more bugs in it by now Needless to say, a bunch of horseflies still harass me every day every time I walk outside. I don’t normally like to give bad reviews cause every situation is different, but I gotta be honest.
