Shaving your legs to deter ticks

Leave a reply

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.

Instragramming invasive species in Hawai’i

Leave a reply

During my recent trip to Hawai’i I got to wondering how conservation organizations use Instagram to educate the public about invasive species. A quick search pulled up several groups that seem involved, at least occasionally, and I’ll list here just in case you want to follow them (# followers in parentheses):

hawaii-invasive-species-instagramPart of my reason for wasting time on the above was because when I posted a photograph of an introduced frog, I wasn’t sure if anyone on Instagram might care. Potentially, there might be a group or two that might want to be mentioned, in the off chance that a species hadn’t been noticed at that particular location. Not being a native (I was a baby when I lived there), I had no idea which groups to tag, though, so all I did was add some hashtags for the species name as well as #invasive #introduced #nonnative … with the hope that somebody might find it useful someday (unlikely). But the process got me wondering how groups use Instagram to get the word out on how to control invasives. Here are some thoughts on how to do it, with apologies to the groups who are already doing it:

  1. To build buzz about your organization and its goals, repost images of others that show the species you are trying to control. People love to have their images reposted or their accounts mentioned. You can find these images by following people (duh), or by searching Google for Instagram photos with particular keywords (e.g., site:instagram.com coqui kauai). The routine is just this: ask them if it would be OK to be reposted/featured … and then give them credit by including Instagram handle (i.e., don’t just give the photographer’s name).
  2. If you don’t want to feature other people’s images, at least patrol other people’s posts that relate to invasive species, endemics, restoration, etc. For example, if somebody posts an adorable photograph of a small frog and says, “Love this little guy; going to send to my uncle on Kauai for his birthday!” … you can urge them not to do that. Or, when somebody posts about clearing invasives from property, you can say thanks (and perhaps invite them to a volunteer day if you’re group is local). And it’s not just people making posts about invasives … many companies are active in promoting pono and have thousands of active followers (@southmauispearfishing, e.g., has *dozens* of posts about invasive roi and what to do about them). The more you interact by favoriting and commenting, the more people on a particular island will see your organization’s work as important and worth supporting.
  3. If your organization has volunteer work days, add an “Instagram name” column to your sign-in sheet. Then mention each person when you post photos from the event (you should do that!). People love to be publicly thanked. Example. Another example.
  4. In your bio and in your posts, remind folks to tag their own images with #invasive #hawaii (or whatever) and species name so that the posts can help educate their followers. Example. Example. You can also dream up custom hashtags such as #hawaiiinvasive if you want (that’s from @kauaiisc, by the way).
  5. When you make presentations about invasives at local schools, show your Instragram handle at start and end. Young adults increasingly don’t care about your web site, your twitter feed, or your phone number but you might get them to follow on Instagram.
  6. Award prizes to people reporting or posting certain kinds of images. People love contests. For example, send some swag to person who posts best selfie with gold dust day gecko (example).
  7. If you have a Facebook page, add a tab for your Instagram feed. It’s easy. You should also automatically add your Instagram posts to your timeline.
  8. If you include a phone number in your bio for reporting a particular species, include an area code in case clueless tourists see call to action. Repeat this number in posts, too … because somebody might not bother to visit your actual home page.
  9. Check Instagram regularly to see whether anyone has posted an image of a species of special concern. For example, you can run a search for “site:instagram.com snake hawaii” to patrol for snake sightings (the search results are mainly Hawaiian shirts with snakes). There used to be several ways to automate such Instagram searches and receive emails … but Instagram blocked them.
  10. If your organization doesn’t have an Instagram account, fix that.
