Living in the south, mosquitos are a huge problem. These stickers come in a pouch that makes it easy to get to. I applied 2, one on my arm and one on my ankle . I was able to work on my plants and crafts all evening without having to swat at mosquitos all night. They seem to work great on me. I applied one on my granddaughter but didn't work as well. She still had less bites than usual so they did help. I am outside every night and will continue to use these. I recommend this product. We need all the protection from these deadly mosquitos so use these. I feel protected.
