The Dengue Defender uses the scent of Vitamin B1 and Vanilla to disorientate and effectively repel mosquitoes.

Its key natural ingredients – Vitamin B1 and Vanilla – ensure that the spray is safe for the whole family, including pregnant or breastfeeding mothers, babies, children, elderly and pets. It has a pleasant sweet smell and is even safe to be consumed if sprayed accidentally into the mouth.

The spray is light and non-greasy, gentle on sensitive skin and moisturising. Unlike other common insect repellents, it is eco-friendly and does not contain alcohol, oil, DEET or toxic ingredients.
