The Thermacell Mosquito Repellent system is fast becoming the first choice for those in the know when it comes to finding an effective and reliable portable insect repeller.This innovative system - used successfully for years by the US Military - utilises a vaporised active ingredient which is dispersed into the air and provides lasting protection against 98% of mosquitos and other airborne blood-sucking insects including the Scottish midge, creating a protection zone of over twenty square metres around the device.The active ingredient is non-allergenic and harmless to pets and other animals when used as directed, and makes an effective alternative to messy lotions and creams.Completely portable with no cables or cords, the device is powered by butane gas cartridges, and, as no open flame is required to vaporise the pesticide, it is completely safe to use in any outdoor setting.Recognized by leading entomologists, outdoor enthusiasts and even the U.S. Department of Defence, the Thermacell Mosquito Repellent system represents a huge leap forward in insect repellent technology.
