Infused with citronella oil, these bracelets repels mosquitos. Citronella works naturally to mask the scents of carbon dioxide and lactic acid that mosquitos are attracted to. You can wear these bracelets on your wrist, ankle, or belt loop. You can even hang them around your yard, camp, or tent and on your stroller or backpack during a walk or hike. The mosquito repellent bracelet is made of silicone. Your logo and color are welcome.
