Waspinator - Europe's best selling Wasp deterrent.How do Waspinators work? Waspinator creates a large wasp free zone without killing wasps and without disturbing the insect world in your garden. No mess or chemicals to clear up, no traps, no maintenance, and no dead wasps. Scientifically proven and based on an age-old remedy Waspinator acts as a decoy just like a scarcrow and naturally repels wasps by mimicking an enemy wasp nest. Why do Waspinators work? Wasps are very territorial, if a wasp goes too near another colony's nest, the nest's defenders will attack it and chase it away. Consequently wasps instinctively know to stay well away from nests that aren't their own. Leave it out all season and they will stay away-they think the garden is another colony's territory. Waspinator is designed to look like an enemy nest : the colour, shape and size mimic a wasps nest. The horizontal striations make it look fibrous and layered to the wasp, just like a real nest. Contains 2 Waspinators.
