First of all, did you know that the scientific word for ear wax is “cerumen”? Learn something new every day.
I’m sure we’ve all had ear wax encounters. Sci has often wondered, if she let her ear wax build up enough, if she could make a candle out of it like that Shrek guy.
Unfortunately, I always got too grossed out by myself before ear wax levels ever got close to candle level. But what if there was a good use for earwax? What if…you could use it for insect repellent?

I’m sure we all know about malaria, yellow fever, and other insect-borne diseases. Malaria alone accounts for 250 million cases annually and 1 million deaths. There are lots of things that one can do to try and stay safe, including insect netting, controlling mosquito spread, etc. The cheapest and easiest is…insect repellent. Unfortunately a lot of insect repellents that are the most effective contain things like DEET, which isn’t biodegradable, and which also can’t be used on children under 3. Children under 3 can still get malaria, and so it’d be really good to find an insect repellent that was a little safer.
Apparently ear wax has a bitter taste, but is also a fungicide, antibasterial AND an insect repellent! (Tell that to all the bugs that have flown in my ear while I’m running. I’d like to think it’s by accident). It has both lipid (fatty), and non-lipid portions, which means that it is partially waterproof (another plus). So this paper says: why not try and make an insect repellent from ear wax!
To Sci, this seems like a pretty cool idea. Think of the possibilities!! In these tough economic times, you could sell your earwax! There could be charity drives for earwax. Ear wax is a continuously renewable resource, and completely biodegradeable. Of course, no one has ever actually tested to see if ear wax is in fact a bug repellent. I say we do it. I need some hardy soul out there willing to store up their ear wax, rub it on their body, and let me know if it works! Living in marshy environments a plus, excessive ear wax production would be an unanticipated bonus. I would like the see the data in five months’ time, which will give you the whole summer to have multiple tests. Any takers?
