Yates Home Pest Indoor Fruit Fly trap comes with 2 traps and a lure. It lures & kills drosophila melanogaster (commonly known as vinegar flies or indoor fruit flies) that are often spotted near fruit bowls, indoor bins and kitchen sinks. It does NOT control QLD or Mediterranean outdoor fruit flies, fungas gnats or common household flies. It uses a food-based, pesticide-free liquid lure that lasts up to 45 days. Trapped flies can’t escape to continue breeding.
