Shanghai mosquito repellent ring mosquito repellent stickers are all "unlicensed" products with myths

When it came one year to "fight mosquitoes", compared with traditional mosquito repellents, mosquito coils, and toilet water, a new type of mosquito repellent bracelets and mosquito repellent stickers that can be worn on the hands or on clothes began to become popular
.
Most of these products claim that the ingredients are non-toxic, pure and natural, and have a significant mosquito repellent effect
.
Is this really true? According to the national "Pesticide Management Regulations", mosquito repellent and anti-mosquito products are included in the scope of pesticide management, and pesticide registration certificate number, pesticide production approval document number and product standard number must be obtained before they can be marketed, and relevant information must be marked on the packaging
.
However, the reporter visited the supermarket in Shanghai and found that there was no pesticide registration certificate number on the product packaging of the mosquito repellent ring and the mosquito repellent patch, and there was a potential risk when used
.
Mosquito repellent rings and mosquito repellent patches are selling well Yesterday, the reporter visited a number of supermarkets to investigate the mosquito repellent rings and mosquito repellent patches sold in the market
.
In the Carrefour supermarket on Xietu Road in Xuhui District, the reporter saw an anti-mosquito bracelet called "Shiyingbao", which claimed to be rich in plant anti-mosquito essence, but there was no specific ingredient description on the product label
.
There is also a mosquito repellent stick with the brand, stated on the packaging component is "nano lemon oil, citronella nano essential oil, lavender essential oil nano variety of plant extracts"
.
According to the clerk, with the increase of mosquitoes in summer, these two products have entered the peak sales season
.
In the Lingyun store of the Wal-Mart Supermarket on Laohumin Road, the reporter saw a "Mine Bear" brand mosquito repellent patch, a pack of 30 pieces priced at 24.
9 yuan
.
The package says "Using natural anti-mosquito plant extracts combined with polymer nanotechnology", and it also states the words "No DEET"
.
Mosquito repellent rings and mosquito repellent stickers are also hot-selling products on the Internet.
The reporter searched Taobao using "mosquito repellent rings" as a key word.
A total of nearly 400 products were found, with prices ranging from a few cents to a few hundred yuan
.
Some online stores have sold more than 10,000 pieces
.
The product being sold is "unlicensed" listed in the pesticide registration database of the China Pesticide Information Network.
The reporter entered "mosquito" in the field of prevention and control.
No entries for mosquito repellent stickers and mosquito repellent rings were found in 1788 pieces of registration information.

.
The reporter entered the brands and manufacturers found in each supermarket one by one, and found that these products were all "unlicensed" on the market, without indicating any necessary numbers (pesticide registration certificate number, pesticide production approval document number and product standard number)
.
It is reported that the Shanghai Municipal Bureau of Quality Supervision has conducted risk monitoring on mosquito repellent rings and mosquito repellent patch products on the market and collected 30 batches of samples
.
After testing, it was found that none of the 30 batches of mosquito repellent rings and mosquito repellent patch samples had been registered for pesticides.
Among them, mosquito repellent esters were detected in 4 batches of samples, which is a chemical ingredient with certain toxicity
.
The mosquito repellent effect is not so magical.
The reporter found that in order to let consumers buy with confidence, some manufacturers claim that the products are 100% plant ingredients, "purely natural and non-toxic", and they will also specifically indicate "not free from avoidance" on the product packaging.
Chemical ingredients such as mosquito amine"
.
In this regard, Zhou Wenjing, a traditional Chinese medicine pharmacist at Liqun Hospital in Putuo District, said that according to the theory of traditional Chinese medicine, the principle of plant mosquito repellent is to use a certain type of natural aroma that it volatilizes.
This kind of smell is very disliked by mosquitoes.
Purpose
.
"Theoretically, aromatic plants that can volatilize this scent can indeed play a certain role in repelling mosquitoes, but the effect is related to the concentration and distance of the odor.
As time goes on, the odor will become lighter and lighter.
The mosquito repellent effect is getting lower and lower
.
The so-called natural mosquito repellent ring and mosquito repellent patch will contain such plant ingredients, but often these products have been in circulation for a long time, and many odors are volatilized.
The mosquito repellent effect is not so
magical.
" As for essential oils, there is also no "magical power" as advertised
.
Plant essential oils can affect mosquitoes in different ways by acting on their internal systems and play a repellent effect
.
However, essential oils are extremely volatile, and the concentration of essential oils should not be too high, otherwise it will cause harm to the human body
.
Therefore, using the fragrance of essential oils to repel mosquitoes does not have much effect
