Wasps are repelled naturally. The ultra-fine spray mist signals to wasps "Caution - cool rainwater," triggering their instinctive natural reaction: they flee! The spray mist covers an area of approximately 1 m². Unlike conventional spray bottles or cans, the ultra-fine mist prevents the watering down and sogginess of your food. It operates with pure water. Recommendation: distilled water to prevent nozzle clogging.
