Bikini Waxes Wiping Out Pubic Lice

Pubic lice have plagued mankind for thousands of years, but the itchy pests are now facing a enemy that threatens to wipe them out: bikini waxing.

Also known as crab lice, the tiny insects lay their eggs on pubic hair. But as Brazilian waxes and other hair-removal procedures become more common among men and women, the bugs' breeding cycle is interrupted, and populations are now plunging as low as bikini briefs themselves.

The main sexual health clinic in Sydney, Australia, hasn't seen a woman with an infestation of pubic lice since 2008, reports Bloomberg, and cases among men have fallen 80 percent in the past decade.

A 2011 study published in the journal Sex Roles revealed that 80 percent of college-age men and women in the United States have removed some or all of their pubic hair.

The popularity of bikini waxing exploded after it was given exposure on television shows like "Sex and the City," Bloomberg reports. Men are signing up for extensive hair-removal treatments like one called the "Sunga" that costs $90 and removes all pubic hair, including on the scrotum, according to the Daily Mail.

Pubic lice are a different species from head lice, and evidence suggests humans caught pubic lice from gorillas some 3 million years ago (no not from human-gorilla sex, but rather from sleeping in their nests or eating apes), according to a 2007 report detailed in the journal BMC Biology. Because a lice infestation is easily treated with insecticidal soaps, and because they don't spread any diseases, public health organizations keep few records of infestation rates, Bloomberg reports.
