Summer is coming and there will be more mosquitoes. Although there are fewer mosquitoes in the city now than in the past, it is still annoying when a mosquito flies over your ear while you're trying to sleep. I usually burn mosquito coils, but they smell bad, and if they can make mosquitoes dizzy, they probably aren't good for people either. This summer, you can try making a DIY mosquito trap, which is said to be very effective. More importantly, it's very environmentally friendly.
