I’m going to link to an older post but it is useful. It is about 10 thrifty ways to keep mosquitoes away. I don’t know what’s the mosquitoes scene in your area but if you live in a place with lots of mosquitoes (as we do) you either have to sleep inside your mosquitoes-net or use all kinds of unhealthy mosquito repellents. The solutions mentioned in the link are great, but here’s a quick tip to keep mosquitoes at bay: put a few tablets of camphor in a cup of water and place it in the room. Mosquitoes will go away.
