well I have it in the vegie garden that has the lettuce, tomatoes, basil and ummm, trying to think of what I planted in there yesterday... and differently to last year in that particular patch, I don't have any flying anything's hanging around so maybe it does work... and for a couple of bucks it's probably worth a shot.. I had that many flying insects and butterfly's around my vegies last year it became ridiculous, I tried EVERYTHING and nothing worked... heard Jamie Oliver's (I LOVE HIM) gardener saying he gets the 'hoover' out, shakes the plants and then hoovers the fliers...lol
