The Fruit Fly Trap from Zero In kills fruit flies without using hazardous chemicals. The product is hygienic and can be safely used near fruit, vegetables and open wine bottles to provide up to 30 days of continuous and discrete control. Fruit flies are drawn down into the non-toxic trap solution, where there is no escape. Just pour the solution provided into the trap and place in the worst affected area. For severe infestations, or protection of a large area, use more than one trap.
