The "No Flies Zone" from Inventorpreneurs of Tulsa, Okla., is a sneeze-guard encasement for outdoor buffets that uses forced air to keep pests away. The air-wall barrier is designed to create sufficient air pressure to keep flies, wasps, bees and other flying insects away but will not affect food presentation. The system is available in both pre-fabricated sizes and custom sizes, suitable for service and prep areas. The units are easy to break down and transport; lighting for nighttime events is optional.
