Thermacell offers a range of portable mosquito and flea repellents that use cartridges soaked in active d-alethrin .A synthetic equivalent of the ingredient found in chrysanthemums, which is used by flowers to protect against pests. Unlike the substance Deet, alethrin is a natural substance and is therefore completely safe for humans and animals.Thermacell MR300 is also safe for allergy sufferers, odourless and environmentally neutral. Tests carried out confirm Thermacell's effectiveness at 96%, which means it is without doubt the most effective repeller using alethrin.ActionThe device works like a tourist gas stove. A replaceable gas cartridge is used to feed the heating element. The heat generated heats the d-alethrin cartridge.
