Fruit flies reproduce with such zeal that the sight of one in the kitchen should raise the alarm bells. Without control they can quickly become a real nuisance. This glass Fruit Fly Trap can be hung or placed on a flat surface. It has a durable glass stopper on the top and an entrance underneath. Place a small amount of apple cider vinegar inside the trap - the CO2 it gives off tricks the flies by simulating the rotten fruit they crave. The trap is 14cm (5.5") tall by 10.25 (4") in diameter.
