I know that when you think of bug repellents, you think of a spray. When I set out to make a bug repellent that would be effective for the entire family, there was one issue that kept coming up. Just because bug repellent is safe for your skin, it doesn't mean it should end up in your lungs. Young children cannot effectively hold their breath to prevent aerosolized products from ending up in their lungs. The solution was to create a solid bug repellent.
