The pestNOmore® Housefly Trap is scientifically designed to attract and capture irritating houseflies. Houseflies are more than a nuisance; it has been scientifically determined they cause a health risk to you and your family by transmitting disease-causing organisms and parasites. Like all Green Earth Products', this trap is scientifically designed on insect behavior and contains no poisons or toxins of any kind. It is safe near children and pets, and is easy to use. The Housefly trap will last for 3 months or when it is full of flies or dust, whichever comes first.
