Mosquito repellent principle:
Plants with mosquito repellent effect generally have a special smell. The behavior of insects is the result of the recognition and integration of various receptors, including sense of smell, by the central nervous system of insects. The blood-sucking behavior of blood-sucking insects is a complex process. Repellent mainly acts on the olfactory receptor of insect antenna, which affects the insect's feeling of host odor, thus preventing people from being bitten or attacked by insects.
Plant essential oil is a secondary substance in plants. These substances are chemical substances that resist insect feeding during the long-term co-evolution of plants and insects, and have many biological activities such as contact killing, stomach toxicity, avoidance, antifeedant and growth inhibition. Compared with chemical mosquito repellent, plant mosquito repellent has the advantages of fast degradation, less residue and low toxicity to human body.

Other mosquito repellent methods:
1, perfume bath
Use less soap to bathe the baby. Because mosquitoes like nectar, if you use perfume, cosmetics, cream and other items with floral fragrance, mosquitoes will smell the fragrance. However, not all perfumes will attract mosquitoes. For example, sandalwood-flavored baby mosquito repellent perfume can repel mosquitoes.
Step 2 eat delicious vegetables
Give the baby more vegetables. Some vegetables contain odors that mosquitoes don't like, such as vegetables containing carotene, garlic and other spicy vegetables. After the baby eats them, mosquitoes will stay away from him. Mosquitoes don't like the smell of garlic secreted by human body.
Step 3 wear light clothes
Let the baby wear light clothes. Aedes mosquitoes (also known as spotted mosquitoes) like to park on black clothes. Mosquito bites have a lot to do with the color of clothes people wear. If you wear dark blue or brown clothes, you will be more vulnerable to mosquito bites.
