Oh, my! For as long as man has taken to the woods, he has searched and searched for that magic “formula” that will keep biting insects away. For as long as man has searched for the secret there have been too-numerous-to-count “wives tales” formulas that “really do work”.

Take for example the blog I posted back in March about the use of Listerine mouth wash as an insect repellent. There have been over 30 comments from people who swear by it and those who will laugh in your face should you mention it.

The things that man has tried to beat off the swarming mosquitoes, black flies, chiggers, etc. could leave the most knowledgeable research scientist scratching his head. Some of those concocted formulas could kill or repel bigger things than tiny insects I’m sure but our quest remains undaunted. The search must go on.

One of the best known killers of insects, DDT – Dichloro-Diphenyl-Trichloroethane – is banned from use here in the U.S. Growing up in rural Maine in the 50s and 60s, my small home town budgeted money each year in order to hire a spray plane to criss-cross the village air space spraying DDT to kill unwanted bugs. I can honestly say it worked. It was a rare occasion to be playing baseball on the town’s Little League field and find a biting insect. Of course there were no songbirds and the like either but we didn’t get bitten.

Some of my growing up buddies and I laugh even today as we relive the days when the spray plane arrived so we could run outside, look up toward the clouds and wait to feel the mist of DDT fall gently on our faces. All that and there’s nothing wrong with me….wrong with me……wrong with me……wrong with me……wrong with me……

Sorry, I don’t know what happened.

Later came the development of DEET – N,N-Diethyl-meta-toluamide. DEET has been used for several years now as a repellent, whereas DDT was a kill-em-dead-on-contact pesticide. DEET has been relatively effective but isn’t recommended to be used on your skin, especially on kids.

DEET seemed to work best on mosquitoes to repel them but scientists really didn’t know why until recently a study seemed to indicate that it makes human scent “invisible” to those biting, vicious and hungry insects. With that to work on, could it be that someday someone will discover a different “chemical” that will even be more effective than DEET with no residual side affects – unlike what has happened to me?

Black Bear Blog reader “jes” sent me an email yesterday with a link to a National Public Radio story about just such a thing. You can read or listen to it for yourself but here’s an interesting tidbit from the story.

“And we’re finding lots of interesting things that look nothing like DEET that are much more potent, at least in the lab,”

Is it really that simple? Could it be that once someone seemingly discovers how DEET works, researchers have been able to “model” other things that will work as good or better? If so, why has it taken so long?

Kelli Miller Staci for WebMD has a bit more information on the work done by researchers at the University of Florida on insect repellents. The article goes a bit further than that of NPR in actually telling us what these “magic” chemicals are that work better than DEET.

Alan Katritzky of the University of Florida and colleagues used artificial neural networking software to predict how certain compounds called N-acylpiperidines would keep mosquitoes from feeding on human flesh. N-acylpiperidines are related to the active ingredient in pepper. The researchers identified 23 strong candidates, which they expected to be as effective as DEET.

So, there you have it. The newest information on how to repel insects. Simply douse yourself in pepper and head outdoors. Maybe not so fast. I think there might be more to this.

What I do find interesting though is that “under laboratory conditions” DEET is said to be able to repel mosquitoes for an average of 17.5 days and these new pepper-based ingredients will last up to 73 days. I can tell you from experience that DEET products in the “deep woods” will not repel mosquitoes for 17.5 days. Perhaps 17.5 minutes before the next dose needs administering.

And do we really want to repel those dastardly bugs anyway? Don’t those biting, unrelenting insects work as a repellent of their own? I had a short exchange of emails with the same reader, “jes” and he brought up an interesting question or two.

But I wonder if “the bugs” (especially in FL) don’t determine two important aspects: one how long or if we spend any time at all in the woods, hunting, etc. and how comfortable we are there. And two, how many woods will be left for wildlife if the bugs are gone…(it seems to slow development), in FL, at least!

Never fear “jes”! There just might be protection for those biting insects and their natural human repellent might just be able to do the trick. Many of you might recall last October I told you about the U.S. Fish and Wildlife Service issuing the “Draft Mosquito Management Plan“.

I didn’t read anything in that plan that would call for the control of insect repellents, only pesticides but you can be sure that in this day of animal rights extremists and their undaunting affection with the courts, they will find a way to stop us humans from repelling biting insects.

The good news in all this seems to be that there may be hope on the horizon that we can get relief from biting insects with something that may not be as harmful as DEET. I would suppose that for those with allergies to pepper, you’ll need to hope for something else.

AAHHH CHEEEEEEWWWW!
