The Fruit Fly Trap captures adult fruit flies, also known as vinegar flies. The trap works by intercepting flying insects in search of food in your home. Fruit flies occur almost everywhere, and are attracted by human foods, especially over-ripe fruit, fermenting products or decaying fruits and vegetables. Flies lay eggs that hatch into larvae. In the summer, new flies emerge after 8 to 10 days. Trapping the flies, along with proper composting or disposal of wastes, will effectively reduce the numbers of flies present. Long-term use of the Fruit Fly Trap will reduce troubling infestations without the use of toxic chemicals. Effective, Safe, Easy to Use! Non-Toxic, Environmentally Friendly! Comes with 3 traps. Replace every 3 months or sooner. Reg. Price $4.99
