- Head lice are a lousy (forgive the pun) affliction that were once treated by completely shaving the victim's head and applying nasty chemicals to the scalp in order to do away with the blood-sucking pests. It was messy and it often took a ridiculously long time to expel the vermin; in the meantime, patient zero (usually an innocent child in elementary school) became a social pariah shunned by the neighborhood's parents and their easily impressionable offspring. Thanks to the technology of a little machine called the Lousebuster, however, lice infestations may now be easily and quickly eradicated wherever they may strike. Here's how the Lousebuster kills head lice without chemicals.
