Mosquitoes can be a pain in the "you know what". You certainly can put on some repellent such as Off! or burn a citronella candle. Both will work.
However, wouldn't you like some natural insect repellent for your entire yard? Well look no further.
The five plants shown in the picture each give off their own unique
scent which can throw off the sensory perception of mosquitoes ... i.e.
they can't find you.
Sure this isn't 100% fail proof, but it will help, and you will also get a really nice looking landscape in the process.
