Mosquitan Pets Mosquito Patches. The safe anti-mosquito solution for your pet. Part of the new Mosquitan Pets range, these anti-mosquito patches provide a safe and natural anti-mosquito solution for your pet. Each patch contains a small cushion plaster filled with microcapsules of essential oils of Eucalyptus citriodora, Pelargonium graveolens (Geranium) and Tea Tree. You simply place the adhesive patch onto your pet’s collar or bed and squeeze. Once squeezed each patch lasts for up to six hours. Designed especially with cats and dogs in mind, the patches are DEET-free, well-tolerated and safe. The essential oils are contained within a non-permeable adhesive layer that prevents them from coming into direct contact with your pet’s skin or fur. One patch covers an area of one cubic metre.
