Head Louse SEM Image

This is a scanning electron micrograph of a head louse (plural: lice).  The eggs, known as nits, can be very hard to kill and can spread an infestation easily. 

Our special 10000ppm high level quat strips are used to measure the strength of Barbicide to ensure they eggs are killed.
