Mosquito-repellent incense is a common method to repel mosquitoes. The main component of mosquito-repellent incense is insecticide, generally pyrethroids, which is less toxic. However, some mosquito-repellent incense uses organochlorine pesticides, organophosphorus pesticides and carbamate pesticides. Although this mosquito-repellent incense increases the mosquito repellent effect, it is much more toxic. In addition, the smoke of mosquito-repellent incense will make the baby feel uncomfortable, even smokeless mosquito-repellent incense will inevitably have smoke. Under normal circumstances, mosquito-repellent incense should not be used indoors, because the respiratory system of infants and young children has not been fully developed and the skin absorption capacity is strong.

The principle of electric mosquito-repellent incense is to inhale pesticides into paper and evaporate pyrethrins through hot air. Although pyrethrins are less toxic and safer, electric mosquito-repellent incense has a strong killing effect on microorganisms, so families with infants should try not to use it. If you use electric mosquito-repellent incense in your baby's room, try to put it in a well-ventilated place and don't use it for a long time.

The types of pesticides should be changed frequently to avoid mosquito resistance.

6, anti-mosquito liquid

Mosquito repellent is the most commonly used outdoor mosquito repellent. The main component of mosquito repellent is DEET, and its odor can directly act on the tactile organs and chemoreceptors of mosquitoes to drive them away.

Mosquitoes are afraid of the smell of mosquito repellent, so the stronger the smell, the better. In general, the concentration of anti-mosquito liquid is less than 50%, which has no side effects on adults. But if there are children at home, the concentration should be less than 10%, or not at all.

Using mosquito repellent can better prevent mosquito bites. Apply a little mosquito repellent to your skin. When a mosquito approaches you, it will disturb its senses and lose its ability to bite. Light-colored clothes can also prevent several kinds of mosquitoes from attacking. Installing mosquito repellent curtains on windows can also repel mosquitoes.

For the baby, try it on the inside of the baby's upper arm before use (the skin here is the most delicate and sensitive), and then use it in a large area after confirming that there is no adverse reaction.

In addition: put several boxes of open cooling oil and wind oil essence in the bedroom; Eating garlic, taking vitamin B 1 orally (but not taking it in large quantities for a long time) or dropping a few drops of vitamin B solution in the bath can also prevent mosquitoes; Wearing light-colored clothes in summer can reduce mosquito bites. Installing orange light bulbs indoors can produce good mosquito repellent effect, because mosquitoes are afraid of orange light. Rub the dried Folium Artemisiae Argyi into rope shape, light it and put it indoors. Smoke can repel mosquitoes. Burning dry tea leaves can drive away mosquitoes. Put 35 ml of sugar water or beer in an empty wine bottle on the table or in a place with many mosquitoes indoors. When mosquitoes smell sweet wine, they will inject it into the bottle and stick it to death.

Remember: as long as you can accumulate a little water-in a beer bottle or a broken tire, countless mosquitoes may grow in a week.
