It’s hot and rainy in summer, so how to repel mosquitoes has become the trouble of many citizens. At present, all kinds of mosquito repellent products are popular in the market. Among them, mosquito repellent bracelets, mosquito repellent liquid, "toilet water for mopping the floor" and other products are called "physical mosquito repellent" and "non-toxic", and some "online celebrity" products even claim that there must be no mosquitoes within 200 meters. Are these mosquito repellent products really effective? Recently, the reporter visited the investigation and bought a variety of mosquito repellent products for testing.

Market: Online and offline mosquito repellent products sell well in summer.

There are many mosquitoes in summer, and the public’s demand for mosquito repellent products has increased. Recently, the reporter visited some supermarkets and found that mosquito repellent products such as mosquito repellent incense and toilet water are selling well. In the Nanning exchange, various brands of mosquito repellent products are neatly placed in the daily necessities sales area. Many shopkeepers said that traditional mosquito-repellent incense, mosquito-repellent incense tablets and electric mosquito-repellent incense liquid were generally welcomed by the public. Among them, the most popular one is electric mosquito repellent incense. "A bottle of 6 yuan’s electric mosquito repellent incense can be used for one month, and you can use it as soon as you press the key." A female shopkeeper said that the sales of electric mosquito-repellent incense liquid are hot recently, and the sales volume in the store is more than 100 bottles a month.

Traditional mosquito-repellent incense is popular with the public.

In many supermarkets, such as Wal-Mart’s Jiangyu Century Plaza Store, all kinds of mosquito repellent products are placed in a conspicuous position, and the price ranges from several yuan to hundreds of yuan, which has become the most popular commodity at present. In addition to the common traditional mosquito-repellent incense, anti-mosquito spray, mosquito-repellent incense tablets and electric mosquito liquid, there are also LED vertical electric mosquito swatter (mosquito killer+electric mosquito swatter in one), various types of mosquito killer and smokeless and odorless mosquito repellent products available to children, which are rich in variety.

In the supermarket, products such as electric mosquito swatter, mosquito-repellent incense and insect repellent spray are placed in a conspicuous position.

On the Internet, in order to attract consumers, the slogans of various mosquito repellent products are "louder" than one. "Second mosquito repellent, 0 alcohol, no mosquito repellent, postage refund." "There must be no mosquitoes within 200 meters, and babies and pregnant women can use it." "40 years without mosquitoes, 40 years to protect." "It can kill 70,000 poisonous mosquitoes a day." ….. The reporter found that mosquito repellent products such as mosquito repellent spray, powerful mosquito killer, and household ultrasonic mosquito repellent sell best.

Citizen: Some pay attention to the effect and some pay attention to safety.

Mr. Chen, who is buying electric mosquito-repellent incense, said that his family lives on the second floor. In summer, there are more mosquitoes and mosquito-repellent incense is used faster. This summer, he has come to the supermarket for the second time to buy mosquito-repellent incense. "I have used many mosquito repellent products for so many years, and I think the traditional mosquito repellent incense is the most effective."

Compared with male consumers, female consumers pay more attention to the safety of products. Considering that there are infants at home, many mothers do not choose chemical products such as electric mosquito-repellent incense, but use physical methods such as mosquito nets and electric mosquito swatter to prevent mosquitoes. "My family generally doesn’t use mosquito-repellent incense, and it relies on electric mosquito swatter to repel mosquitoes." Ms. Yang, a citizen, said that the traditional mosquito-repellent incense is heavy and smoky. This kind of mosquito-repellent incense usually contains pyrethrin, an insecticide. Although pyrethroid has low toxicity, and there is no evidence that this kind of products will have adverse effects on human body, it may also cause irritation to respiratory tract if it is used by a baby for a long time.

Ms. Huang, a supermarket employee, said that citizens with children and the elderly at home pay more attention to the safety of mosquito repellent products when choosing them. Therefore, compared with ordinary mosquito repellent products, mosquito repellent products with simple components for children and odorless electric mosquito liquid are more popular.

Test: Many "online celebrity" products are not worthy of the name.

There are many kinds of mosquito repellent products, and what is the effect? From June 5 to 10, the reporter bought a variety of mosquito repellent products for testing, including plant essential oil stickers, mosquito repellent bracelets, plant fragrance wax tablets, ten generations of mosquito repellent incense kings and other products. On the whole, the test results show that the traditional mosquito-repellent incense and electric mosquito-repellent incense liquid are effective, and the anti-mosquito effects of many online celebrity products are not worthy of the name.

Mosquito repellent products participating in the experiment

Plant repellent mosquito repellent products, such as mosquito repellent bracelets, mosquito repellent stickers, mosquito repellent buckles, etc., are emerging mosquito repellent products in recent years. Most of them contact with the body with pure plant ingredients as their selling points, and their sales targets are also special people such as infants, pregnant women and the infirm. The reporter will hang a piece of plant fragrance wax made of soybean wax, beeswax, spices and dried flowers and fruits on the wall, and you can smell the flavor of spices when you are close to a few centimeters. However, the wax sheet hung on the wall for two days, and the measured effect was very poor, which could not effectively repel mosquitoes. However, the plant essential oil paste and the plant essential oil paste bracelet made of plants such as natural citronella essential oil are attached to clothes and worn on hands respectively, which has a certain mosquito repellent effect, but there are still "red envelopes" bitten by mosquitoes on the arms.

A plant repellent recommended by a well-known online celebrity claims to be safe, reliable and environmentally friendly. It is suitable for indoor and outdoor use and can cover 50 meters in Fiona Fang. The reporter placed two boxes of this product on the balcony on the second floor according to the instructions, but mosquitoes were flying around from time to time within two hours, and two mosquitoes were biting his legs.

During the test, the reporter found that the traditional mosquito-repellent incense and electric mosquito-repellent incense liquid have better mosquito repellent effect. Ms. Zhou, a citizen, said that in recent years, her family bought electric mosquito repellent liquid to repel mosquitoes in summer. When it was plugged in for one night, it was basically not disturbed by mosquitoes when sleeping, and it had no taste. It was no problem to use a bottle for one week.

Reminder: Consumers should read the instructions when purchasing mosquito repellent products.

Mosquito repellent products are one of the daily necessities that citizens buy in summer. What needs to be reminded is that when buying mosquito repellent products, don’t blindly follow the trend, you need to read the description of the products clearly, and children or the elderly at home should pay attention to buying safe and reliable mosquito repellent products. Many "online celebrity mosquito repellent products" are advertised with natural ingredients such as plants and herbs, without corresponding registration, and often without toxicological test and efficacy test, so there are safety risks and uncertainty of mosquito repellent effect.

According to the Opinions on the Identification of Mosquito-repellent and Mosquito-repellent Products issued by the General Office of the Ministry of Agriculture and Rural Affairs in September 2021. If the label and instructions of the product indicate that the product has the function of preventing mosquitoes and repelling mosquitoes, the product belongs to the category of pesticides, regardless of whether the effective components are chemical components or plant-derived components, and should be managed according to the law. According to Article 2 of the Regulations on Pesticide Management and the Opinions of the General Office of the Ministry of Agriculture and Rural Affairs on the Identification of Mosquito-proof and Mosquito-repellent Products, all mosquito-repellent products that are not marked with "Three Certificates of Pesticide" on the label are non-compliant products, and consumers should not buy them.

In addition, the staff of 12315 reminded the general public that when purchasing mosquito repellent products, it is necessary to select products produced by regular manufacturers, check whether the product packaging has the pesticide registration number, and check the content of various mosquito repellents in the product ingredients. The vast number of supermarkets and relevant store operators should strictly control the access of the products they sell. If the labels and instructions of the products indicate that the products have mosquito and mosquito repellent functions, the products should obtain pesticide registration certificates according to law.
