Well, that's not how the term is generally used. But, if you prefer, evidence-based data as opposed to anecdote, which is what you are providing. I have traveled and lived in third world countries for many years too, and have not been bitten by bed bugs. And I *didn't* use essential oils *or* pesticides. Doesn't prove anything but luck. We could, however look at Dengue and Malaria rates in places where DEET and other repellents are not available. Or - if you want to go there - deaths from cholera, measles, gastroenteritis and a multitude of other diseases where there is little access to antibiotics and/or vaccines. Until these "manmade" "chemical" measures were developed, about a third of children died before their third year of life. Natural = better is a ridiculous notion. Arsenic, lead, poison oak and rattlesnake venom are natural. I was an epidemiologist and worked as a clinical researcher for many years. There are safeguards to be sure that many studies are not biased by corporate profit motive. It's not hard to find them.
All that being said, even permethrin don't prove to be that effective against bedbugs in clinical trials. In many areas (I don't know about Spain), they have developed resistance to most repellents. Which brings us back to the importance of inspecting any bed and surroundings before you lie down.
Clinical studies usually have to disclose any conflict of interest. Here is one of a number of studies I found on essential oils and bedbugs: file:///C:/Users/PC/Downloads/insects-05-00849.pdf (if you can't open that, do a search on "Efficacy of an Essential Oil-Based Pesticide for Controlling Bed Bug (Cimex lectularius) Infestations in Apartment Buildings")
We obviously come from different backgrounds and have different sensibilities and perspectives. You say you were an epidemiologist; I was an engineer that worked in renewable energy. I grow up on the north coast of California in the 60s, in a time of much debate--about a good many things. I remember (though certainly not in great detail) the debate about DDT and how it was linked to the demise of the California Condor. DDT was outlawed. There is still, I suppose, an argument that DDT is a good thing because it kills all matter of pests, including those pesky mosquitos (little bastards). But at what cost. And who gained at the peril of the condor (and fought to save their gravy train as long as they could). Indeed, humans may have been, may be safer, from mosquitos in a world that uses DDT. But, again, at what cost. And, what eventual cost to human life. Many consider humans top of the heap. But when everything else has died away there is no heap and we come tumbling down, much like the condor.
On another recent thread on much this same subject, a gentleman that said he was retired from the pharma business, substantiated much of my perspective that people are "gullible" and big money is spent to profit from that notion. Just say'n.
I think I'll start a new thread called "The Sky is Blue" and see how much contention that derives. Of course, the sky is blue, many will say. And many others will say, "not at night" or, "not if it's cloudy." Of course, these are true, but it doesn't detract from the initial statement that the sky is blue.
I stand behind my intent in these "bug" topics (and will continue to use natural and toxic-free formulas): There are options and people are free to perform their own due diligence, filter as they see fit, and approach preparation for their travels accordingly.
Cheers,
