Small bugs in the summer Midges and gnats suck blood, do mosquito coils work? How to exterminate

Mosquito coils may be limited in their repellent effect on midges and gnats. Here are some things you can try to get rid of these little bugs:

1.Clear breeding grounds: Midges and gnats often breed in wetlands, rice paddies, sinkholes, or places overgrown with vegetation. Their populations can be effectively controlled by removing garbage, draining stagnant water, pruning vegetation, etc., and reducing their breeding grounds.

2.Use mosquito nets: Installing mosquito nets on the doors and windows of your home or workplace can keep midges and gnats out of the room. Make sure the screen is not broken or defective to ensure it is completely closed.

3.Use mosquito nets: When midge and gnat populations cannot be controlled outdoors, such as camping or outdoor activities, the use of mosquito nets can provide effective protection. Mosquito nets should be tightly woven to prevent midges and gnats from entering.

4.Use insect repellent: Using insect repellent can help stop the bites of midges and gnats. Choose a mosquito repellent product that contains a mosquito repellent ingredient, such as DEET or ICARIDIN. Use properly according to product instructions.

5.Use mosquito coils or electric mosquito swatters: Burning mosquito coils or using electric mosquito swatters can temporarily repel midges and gnats. Pay attention to safety when using and follow the product instructions.

6.Seek professional help: If midge and gnat problems persist and are out of control, consider seeking help from a professional pest control service. Professional exterminators can take more effective control measures to eradicate midges and gnats.

In conclusion, the method of repelling and eradicating midges and gnats needs to be selected according to the specific environment and situation. Methods such as clearing breeding sites, using mosquito nets, nets, mosquito repellents, mosquito coils or electric mosquito swatters can be tried, but if the problem is serious, consider seeking professional help.

There is no absolute effect on these bugs. It is best to do a good job of hygiene, keep it dry and ventilated, disinfect or expose all kinds of cloth supplies, and if you want to completely remove and eliminate it, you may have to close the room and kill it strongly. Pay attention to the food and people and animals are far away, and then open the doors and windows to ventilate when the time is almost up, and the smell is almost evacuated before people can come back.

Apply the insecticide directly, first close the room, spray a little, insecticide, spray and the like, and then the person leaves, comes back in half an hour, opens the doors and windows, and for several nights in a row, these bugs will be gone.

Can kill other bugs.

Insecticidal principle: The main component of mosquito coil liquid is called pyrethroids, and some chloroform, benzene, ether, etc. will be added as solvents.

Pyrethrum is a special family of plants in the Asteraceae family, and is called pyrethrum because its stamen is rich in an insecticidal active substance called pyrethroid or pyrethroid, which has a significant insecticidal effect.

The characteristic of pyrethrin insecticide is that it is neurotoxic, once it is touched by pests, it will quickly embed itself in the nervous system of pests, quickly knock down and kill pests, but its characteristic will not work on the nervous system of humans and mammals, nor will it remain in the body of mammals.

It also has broad-spectrum insecticidal properties, and because of the complex insecticidal mechanism, it is not easy to develop resistance, and it is easy to quickly decompose into water and carbon dioxide in the natural environment, without leaving any toxic substances.

It has a quick killing effect on general small insects and arthropods, but has no obvious effect on beetles and molluscs.

Yes, because it is harmful to people, it is also useful for some other insects.

The principle of electric mosquito coil is to inhale the insecticide (pyrethroid essence) into the paper, and use the hot gas to evaporate the insecticide, and the general effect can be maintained for 6 8 hours. The disadvantage is that the efficacy is good when first used, and there may be a risk of excess, but after 4 or 5 hours, the insecticide volatilizes and becomes less effective, 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.

In the summer, mosquitoes are in abundance again. Mosquito killers, mosquito repellent lamps, all kinds of mosquito coils ......The annual human-mosquito war has started again. In the mosquito control used by people, all the drugs are added, while killing mosquitoes, there is more or less damage to human health, especially mosquito coils, which are more toxic, and you must pay attention to them in the process of use, don't smoke yourself.

Here are a few tips from health experts for the public to use mosquito coils:

First, the use of mosquito coils should be moderate, and try not to use them when they can not be used; Leave the mosquito coil for an hour or two immediately after it is lit, and after smoking the mosquitoes, you should open the doors and windows (close the screens) and ventilate them adequately before entering.

2. Because the brains of infants and young children have not yet developed perfectly, families with pregnant women and infants are strictly prohibited from using mosquito coils and other insecticides, and screen doors and windows can be installed to prevent mosquitoes.

3. When purchasing mosquito coils, the first choice is pyrethrum (made) mosquito coils, followed by low-toxicity pyrethroid mosquito coils such as methrin or cyanoester bromide, and mosquito coils made of organochlorine and organophosphorus insecticides are not purchased and used.

4. Do not buy mosquito coils and mosquito tablets that are not marked with insecticidal active ingredients.

From the perspective of the principle of mosquito control, mosquito coils are also an insecticide. When used, the mosquito coil is lit (or heated) and these insecticides are emitted, which will smoke the mosquitoes down and smoke them to death. Therefore, there is no mosquito coil that is absolutely non-toxic to humans and animals.

Hu Ji, a senior engineer at the Guangdong Provincial Institute of Entomology, said that the insecticides in mosquito coils can not only cause acute poisoning, but also chronic poisoning. Even if it is a slightly toxic insecticide, it is more harmful to humans and animals, and the chronic toxic harm is even more fatal! It is comprehensively evaluated by a series of biological tests such as carcinogenicity, teratogenicity, mutagenicity, delayed neurotoxicity and reproduction, which shows that the chronic toxicity of pesticides is more harmful and complex to humans.

Therefore, do not assume that everything will be fine without acute poisoning symptoms such as dizziness and vomiting, as the effects on the human body sometimes take a long time to be revealed.

According to reports, even if ethroids such as allethrin and cypermethrin are unanimously recognized as safe in all countries in the world, the latest environmental toxicology tests have also confirmed that it has obvious toxicity to the body's nervous system, and long-term exposure will cause dizziness, headache and other neurological symptoms.

Mosquito repellent is mainly composed of the following 4 substances:

》Pyrethroids, solvents, stabilizers, flavors (selective) - pyrethroids are a class of broad-spectrum insecticides that can control a variety of pests, and their insecticidal virulence is 10 100 times higher than that of older generation insecticides such as organochlorine, organophosphorus, and carbamate. Pyrethroids have a strong contact killing effect on insects, and some varieties have both stomach toxicity or fumigation effects, but none have systemic effects. Its mechanism of action is to disturb the normal physiology of insect nerves, causing them to die from excitement, spasm to paralysis.

Due to the small dosage and low concentration, pyrethroid is safer for humans and animals and has little pollution to the environment. Its disadvantages are mainly high toxicity to fish, and it is also harmful to some beneficial insects, and long-term repeated use will also lead to pests developing resistance.

》Pyrethroid** - pyrethroid.

Its roots, stems, leaves, flowers, etc. all contain poisonous insect substances, which is the raw material for extracting pyrethroids, and is a good raw material for preparing various insecticides. Mosquito coils made of pyrethrum leaves can kill mosquitoes and flies, and have special effects on bed bugs, lice and fleas.

= Therefore, mosquito coil liquid may also kill insects other than mosquitoes.
