1. Soap water: First prepare a bowl of water and a bar of soap. Soak the soap in water again and let it dissolve in water. Then continue to pour 2 spoonfuls of sugar into the bowl and stir well. Finally, put it in a place where mosquitoes often go out to completely eliminate mosquitoes. Because sugar is a sweet food, it can attract mosquitoes to feed. Secondly, soapy water is alkaline and mosquitoes' stomachs are acidic, so soapy water can kill mosquitoes.

2, plastic bags to repel mosquitoes: first prepare a bag of water. Put a few more coins in the water. Finally, just hang the plastic bag on the doors and windows. Because the light will be refracted when it shines into the plastic bag, and the coin can diffuse the light, and the mosquito's eyes will escape when they are exposed to strong light, so hanging the plastic bag in the window can play a mosquito repellent effect.
