Works mosquito repellent
Biogent's mosquito blog
I am in the duty-free area of an airport in Sweden after a very exhausting five-hour flight. My ex-wife always wanted to go there with me to go on vacation. I have always been able to successfully defend myself against her and enforce holidays in the south. However, it is a little harder to defend yourself against a business trip and since it is about intensifying teamwork, I accepted the trip. This saved me from four suitcases, various toys and cuddly blankets for the children and I was able to push my hand luggage trolley past the long line of the baggage carousel.
In order to follow the modern age of the north, I also saved the flight tickets and travel documents on my mobile phone. Not only do I save a few trees, but I also have to carry less paperwork around with me and thus save a lot of space in my luggage.
The first thing that catches my eye here at the airport are mosquito sprays in all shapes and sizes. You can usually find snacks, drinks and money changing machines at airports. But mosquito repellent? I did not expect this to be the case. Almost every shop has mosquito repellants, cooling after-bite gel and the like in the shop window. But here, too, I remain true to my motto of this business trip: Carry as little baggage as possible around with you. So for the next few days I will be using an app that promises to keep pests away from me with ultrasound through the cellphone speakers.
When I arrive at the hotel, I sort my clothes, download a mosquito repellent app and activate it. I'm under time pressure because I already have the first appointment with my team. We want to get in the mood for the next days together at the hotel bar. At these prices you can expect an excellent beer, unfortunately I'm already disappointed, because the Swedish beer is nowhere near the Bavarian beer. When it is already midnight, I go to bed and expect a bad headache the next morning. But it's not the headache that plagues me the next day. It's the countless mosquito bites! I'm pretty sure that I turned on the app yesterday and my cell phone is also saying that the app is active.
New day, new app, new luck. But I don't survive the next evening at the bar unscathed either and the next day before breakfast I find myself in a pharmacy where I buy myself a cortisone cream. This time, however, I may be to blame for the pain myself, as I had the cell phone in my pocket and the supposedly mosquito-repelling ultrasound sound might not be broadcast as well. Nevertheless, I decide to stay in my hotel room this evening to allow my skin to relax. So much for my resolution. After the third colleague asks if I am going to eat, I start the fight in a nearby restaurant with app number 3 switched on.
Mosquito repellent app number 3 is even said to have been scientifically tested and is rated 5 out of 5 stars. Nothing can go wrong this time! But even today luck is not on my side. The peanuts at the bar actually taste dry and old here too, and the beer gets worse and worse with every open bottle. The unbelievable happens shortly after midnight: I have my cell phone on the table and was just about to read a message. Then I noticed a mosquito that was floating around my cell phone - and actually landed in the middle of the screen! The "Mosquito Blocker" for € 2.95 is of course in operation.
Back in beautiful Bavaria, I got to the bottom of it all a little closer. Why do I have so many mosquito bites when the apps are supposedly scientifically tested? I find answers to this very quickly:
- There is no scientific evidence that “sound” in the high-frequency range scares off mosquitoes. On the contrary, there is even a study that shows that the bite rate of yellow fever mosquitoes (Aedes aegypti) is increased by commercially available ultrasound mosquito repellers!
- In addition, some of the cell phone speakers are not even able to generate sounds in the ultrasonic range.
If that doesn't convince you, you have to watch this video from the Biogents contract research laboratory! Here you can see what happens when you hold a cell phone in a cage with mosquitoes with the anti-mosquito app turned on:
Next time, I'll do better research before I'm too modern again, and I'll go back to the tried and tested methods when traveling. A good mosquito repellent doesn't necessarily smell good, but it works!
