incognito spray provides 100% efficacy against all mosquitoes and most biting insects. Or in other words if you use it properly you will not get bitten! The active ingredient in every incognito spray, eucalyptus maculata citriodora, has been rigorously tested under extreme conditions by the London School of Hygiene and Tropical Medicine on African mosquitoes and found to be as effective in the short-term as the worlds most deadly insecticide! Yet incognito is certified as 100% natural and can be used by all the family over 6 months of age. It has a fresh and very pleasant aroma unlike any other repellent. It is traded fairly and carries the Vegan Society logo on every bottle.
