Shaving your legs to deter ticks

People shave their legs for a variety of reasons: to look younger, to look less like men, to show off tattoos, to show off muscle definition, to improve athletic performance, to facilitate post-accident wound cleaning (cyclists), and, apparently, to get a pleasurable sensory overload when wearing clothing. But can shaving also protect you from ticks?

I became curious this week after watching this dog tick (Dermacentor variabilis) crawl up my leg:

Here are some reasons why I think shaving would protect from ticks:

  1. Ticks can grip hair, so if you are hairless they can’t climb as fast.
  2. If you have hairless legs you can most likely better feel them crawling up your leg.
  3. When you remove all your leg hair you are removing a lot of sensory distractions caused by wind (experiment on swimmers) and thus you can zero in on things crawling on you.
  4. Without hair, small ticks are much easier to spot. Also easier for others to spot, in case people are ogling your legs.

No experiments on this topic have been done, but I found three relevant snippets on the internet:

  • “One thing that helps is shaving your legs. Not a foolproof way but I would say it reduces them critters by 80%, maybe more. I noticed that when my wife and I were out and she had none, I had around 14 that day.” source
  • “As an experiment I shaved my legs before riding point to point at lbl with KRS and a few others. It was tick season. After 40+ miles of riding I had 1 tick on my sock. Along the way KRS pulled OVER 15 ticks. We rode the same route at the same pace. I’ve kept the hair off ever since.”  source
  • “I’d say its mostly impractical. Although, I know many trail runners (including myself sometimes in the summer) do it to prevent ticks from attaching.” source

One experiment that needs to be done is to count the numbers of ticks on a group of people out for a walk, some of whom shave. But at least in the United States, that would break down to men versus women, and males smell worse than women and thus might attract more ticks, regardless of hirsuteness. And men are usually larger, so there’s the surface area thing that goes against guys, too. So it would be far better to recruit a group of hairy-legged people and ask them to shave just one leg, then march around a field known to have ticks. An ideal group for this experiment might be a men’s swim team right before the season begins. I.e., they all have hairy legs but will likely shave them for the season … so they won’t care. Would be crazy photogenic and fun. Plus great team-building exercise. Would get the college on the evening news I’m sure.

A simpler design might be to just have a motivated group of people (perhaps students in a field ecology course?) conduct tick races on shaved vs unshaved legs. You just need to start them on the ankles and have participants hold still while the ticks make their ascents. That would be equally photogenic and fun, I think.

If somebody does go ahead and conducts this experiment, the next step would be get the CDC to add a shaving recommendation to their tick page. The reaction to that would be really entertaining.
