Mosquitoes are a real nuisance. They not only bite, causing an itching bump, but also have the potential to spread dangerous diseases like Malaria, and West Nile Virus. If hiking, be sure to slap on insect repellent to reduce the likelihood of being bitten. At home, overturn unused flowerpots and remove possible areas of stagnant water to reduce the breeding of mosquitoes. Using candles or potpourri that are infused with citronella oil while outside or planting a citronella shrub is also a good option.
