Why Use Repellents?

Bites from mosquitoes and other insects, as well as ticks (which officially are arthropods, not insects), are more than just annoying. They can lead to lasting health issues and can even result in death. Through proper use of DEET-based repellents, you and your loved ones can enjoy outdoor activities more comfortably. Perhaps more importantly, you’ll help reduce the risk of getting Lyme disease, West Nile virus and a host of other serious illnesses spread by these pests.
