Are gnats the same as fruit flies? I hate gnats... (So does Riley, mostly because the word, 'gnat!' is accompanied by a loud, smacking sound. Riley does not approve of loud, smacking sounds.)
Picked up some of those clear, sticky traps you can put on a window (one side has a thin strip of adhesive, the other side is completely sticky and supposedly treated with pheromones to attract the little dears). Caught quite a few - which creeps me out...
