The Mosquito patch is amazing it is a little sticker that you pop on to your skin, shirt, stroller etc - it is safe for all ages and the best part is it contains no DEET and because it is a little sticker that there is no messy residue and no yucky feeling. While at the cottage in Northern Quebec my cottage was surrounded by millions of black flies that were making it inside through the screen door and through the little gap above and below the door - we were under attack! I applied two stickers to the door frame and the bugs left us alone. Anytime we are out and about with our babies we pop the stickers on the strollers and the babies remain bug bite free - Love this product!
