Query: had many flies, did not even catch ONE...

I had an infestation in my house ! Every day at noon flies in the hundreds enetered through the kitchen window and a black cloud of buzz-buzz hovered over my sink. I obviously kept the windows shut, but a handful of flies still managed to get in. I put up this trap, and not even ONE fly got caught in it... Very disappointing :(
