Please make sure you do not have any still water around you. Wear long sleeves and mosquito repellant around dawn and dusk when they most likely like to feed - or stay home. Get a decent mosquito repellant - DEET is the most effective repellant but do not use high percentages for extended periods of time unless absolutely necessary.

Get a mosquito repellant or magnet and put it far away from your home or living areas.
