The delivery was fast. The fly bait is brought easily as stickers on the windows. I find them very inconspicuous, they covered me no longer to actually. The bait is absolutely deadly for flies. After they ate it, it takes less than half a minute more, until they fall to the ground (whether small or big flies, they must then only return together;) The only (big) disadvantage - and therefore also a point deduction - is that apparently no attractants are included. This means that the fly must happen to land on or run over it ... drawn to it, they are not. And until that happens, the Filegen buzz just merrily around and make the window dirty.
