Mosquito bites not only make people feel red, swollen and itchy, but more importantly, mosquitoes themselves are one of the most common pathogen carriers. In addition to sucking blood, they may also spread some infectious diseases with serious consequences. From traditional malaria, Japanese encephalitis, dengue fever, and yellow fever, to the frightening Zika virus in recent years, all “mosquito-borne infectious diseases” are transmitted through mosquitoes.
More and more anti-mosquito repellent products appear around us. Each claims to be amazing, but how effective is it to repel mosquitoes? You can’t tell the difference by looking at advertisements. We have analyzed and interpreted many products in principle before. This year we decided to experience and test the effects of these products personally through empirical methods.
After several months of contact, we finally completed a series of tests for mosquito repellent products with the help of the Entomological Museum of the Shanghai Institute of Plant Biology, Chinese Academy of Sciences. Today’s is about the most popular mosquito repellent rings, mosquito repellent buttons, and mosquito repellent patches in the past two years.
▲Insect Museum of Shanghai Institute of Plant Biology, Chinese Academy of Sciences.
Explain: Our conclusion is that all mosquito repellent rings, buckles and stickers have no good mosquito repellent effect, and it is not limited to the product brands tested this time. However, the recent habit is not to hide product and brand names, but please don’t think that similar products from other brands will be better.
We chose to test three products this time: PARA’ KITO mosquito repellent bracelet from France, Heguangtang mosquito repellent patch from Japan and domestic mosquito repellent buckle.
One of the reasons why mosquito repellent bracelets are flooded in China is that my country currently does not have national standards for mosquito repellent bracelets. In order to evaluate the mosquito repellent effect of these products, we refer to the national standards for mosquito repellents, that is, put your hand into a sarong full of hundreds of mosquitoes and see if the mosquitoes will avoid it. If the mosquito falls on the hand, it is a failure.
▲Mosquito cage for experiment
The test results may exceed the expectations of users of these products. Let’s see what happened:
/// Palo mosquito repellent bracelet
When we took the mosquito repellent bracelet and reached into the mosquito cage, we can see that the mosquitoes hesitated at first, but it didn’t take long for the mosquitoes to land on the hand, and some mosquitoes stopped on the side of the bracelet.
In order to better show the mosquito repellent range of the bracelet, we put both hands in, and we can see the right hand with the bracelet. There are relatively few mosquitoes, but the left hand a few centimeters away is already covered with mosquitoes.
/// Heguangtang Mosquito Repellent Patch
Mosquitoes crawled around the sticks as soon as the hand was put in, and there were all on the fingers of the wrists, and the palms were covered with mosquitoes.
/// Run this mosquito repellent button
Put the mosquito repellent buckle in your palm, and the mosquitoes are not shy, even some mosquitoes stop on the mosquito repellent to rest.
Let’s take a look at the real effects of these three products in the video recorded on site. Everyone should understand the so-called mosquito repellent effect of these products: If you want to use them to repel mosquitoes, you may need to cover the whole body to be useful.
Analysis of test results
Why are these products that claim to have miraculous mosquito repellent effects so vulnerable in actual tests? Let’s explain the reasons in detail below:
All natural mosquito repellent = not much use
These bracelets and similar mosquito repellent products basically have one thing in common, that is, they promote themselves as “deet-free, all-natural mosquito repellent”. This is their biggest gimmick, but this statement is tantamount to claiming to be invalid.
Like the threatening marketing methods popular in many industries, the most popular way to make money in the mosquito repellent product industry is to intimidate users, saying that DEET is not good in DEET, and it is “deet-free” and is pure natural. How much better.
DEET is one of the most effective and safest mosquito-repellent and anti-mosquito ingredients recognized by various health, epidemic prevention, and medical authorities around the world. It is far better than the so-called pure natural mosquito-repellent ingredients of these products. These “DEET-free” products are nothing more than stigmatizing a normal and safe ingredient, and then selling their own products of inferior quality and more useless at a high price. We have analyzed this in the previous article (click to read: All-natural mosquito repellent products to see their true colors), so I won’t say too much.
Because I’m very curious how these manufacturers can say bad things about DEET, we asked the US official website of the recently popular mosquito repellent bracelet PARA’ KITO in the email, and asked them what they claim to be “DEET-free”. Reason, the answer made us almost choked to death:
“About DEET, we suggest you go online and search for it yourself…”
