The Bodi-Tek Bug Zapper could not be simpler to use. Powered by one AA 1.5v battery, the unit transmits a small charge, which is harmless to the user, to the comb’s teeth. When passed through the hair this charge electrocutes the head lice as they come into contact with the comb’s teeth. This generally kills them outright or causes such damage that they die shortly afterwards. Suitable for adults and children, the Bodi-Tek Bug Zapper provides an easy, clean and effective method of treating head lice.
