What if there are many mosquitoes in the corridor? It's not good to spray mosquito-repellent incense. Even if you kill all the mosquitoes and they are everywhere two days later, how can you kill them?

After cleaning, mosquitoes will come at you, because they don't necessarily come from your side. One is to deal with them. The other is to see if there are any light waves (light blue light) that attract mosquitoes in your building, and if there are, replace them. The two schemes are to install electric shock lamps to trap mosquitoes, which will make a sound similar to police electric batons. Second, if you are afraid of noise, choose a mosquito trap lamp (but there will also be a slight fan)
