Is a mosquito coil to repel mosquitoes or to kill mosquitoes Mosquito coils to repel mosquitoes or k

1. Principle: Mosquito coils with a long history are the earliest insecticides used, and similar mosquito repellent sticks made of traditional Chinese medicine appeared in the Southern Song Dynasty thousands of years ago. Mosquito coils use high-temperature combustion to slowly release insecticides into the air, and the mosquito repellent effect is greater than the mosquito killing effect.

2. Disadvantages: There is also a study that mosquito coils synthesized from wood chips, rice bran, etc., will produce a substance after ignition and oxidation, which may lead to cancer.

3. Suggestion: Experts suggest that mosquito coils are best used outdoors, such as around the home, at the door or in areas with air circulation. In the evening, before dark, the mosquito coil has the best effect on mosquito repellent.

Electric mosquito coils. It's mosquito killing. The use of electric liquid mosquito coils is a room of 10 to 15 square meters, and when the space is too large, the electric liquid mosquito coils cannot play a good role in killing mosquitoes.

When used in a closed and poorly ventilated room, attention should be paid to timely ventilation to reduce the amount of inhalation. Do not use electric liquid mosquito coils and electric mosquito coils for more than 8 hours. The elderly, the sick, and those with allergies should use mosquito nets or other physical methods to prevent mosquitoes.

The principle of electric mosquito coils is to combine insecticides (pyrethroids.

Inhalation of the paper and the use of hot gas to evaporate the insecticide, the general effect can be maintained for 6 8 hours.

The disadvantage is that the effect is good when first used, and there may be a risk of "excess", but after 4 to 5 hours, the insecticide volatilizes completely, the efficacy becomes poor, and the anti-mosquito effect becomes weaker.

The liquid electric mosquito coil that uses the capillary principle to continuously heat and release insecticide substances can just make up for the shortcomings of the electric mosquito coil. Liquid electric mosquito coils can be used continuously for a long time, about 60 days, and can even be released at regular intervals.

There is a lack of empirical evidence for the number of effective mosquito control days claimed by various manufacturers.

In addition, according to the report made by health research, in addition to the release of chemicals such as Yalenin and toluene, there are many unknown and harmful compounds in the electric mosquito coil. If used in a closed room, it may cause severe allergies, such as a sore throat.

Nasal congestion, headache.

Wait. Therefore, it is recommended that when using electric mosquito coils, air circulation should be maintained.

Mosquito coils repel mosquitoes, the main ingredient is mosquito repellent vanilla, which contains the chemical component of pyrethroid resin, and mosquitoes will run away or fall unconscious when they encounter this smell. Mosquito coils are a type of mosquito repellent in which the smoke emitted by a lit drug can drive mosquitoes away or smoke them. Mosquito coils in China have a very long history, and the traditional mosquito coils are divided into two types: incense sticks and incense.

The smoke burned by mosquito coils contains four types of substances that are harmful to humans, namely ultrafine particles-soot (particulate matter smaller than microns in diameter), polycyclic aromatic hydrocarbons, carbonyl compounds (such as formaldehyde and acetaldehyde) and benzene. At the same time, in addition to these four obvious harmful substances, there are also a large number of organic fillers, adhesives, dyes and other additives in mosquito coils, so that mosquito coils can be smoldered without flames.
