The BIO Band collar is a natural product made with essential oils and neem extract, which provides repellent properties against fleas, ticks and mosquitoes. It is a waterproof and repellent collar, specially designed to protect dogs from insect bites and infestations, including mosquitoes, ticks, fleas, lice and sand flies. The collar is effective for 3 months. However, it is specially formulated to repel insects and prevent bites by ectoparasites, so some ticks may remain attached to the animal. It is not deactivated by water or humidity and does not affect the animals sense of smell. The BIO Band collar contains Margosa extract (Neem oil), known for its insect repellent properties, and Lavender oil, which provides a pleasant fragrance while having repellent properties. Thanks to its manufacturing process, this necklace ensures a continuous release of Margosa and Lavender extract. Instructions The collar can be used on puppies over 3 months of age. Place the collar loosely around the animals neck, leaving enough space for two fingers to fit between the neck and the collar. Any excess length should be trimmed. For adolescent and growing animals, check from time to time that the collar is maintaining the correct slack. The collar should be applied before infestation and replaced every 3 months. It will take two days for it to reach optimal effectiveness. Ingredients composition Neem extract (CAS no. 84696-25-3) 20 g/L, lavender oil (CAS no. 91722-69-9) 15 g/L. Classification: Biocide.
